Spur Gears

TOP>Spur GearsWhat is a spur gear ?

Spur gears are the most easily visualized common gears that transmit motion between two parallel shafts. Because of their shape, they are classified as a type of cylindrical gears. Since the tooth surfaces of the gears are parallel to the axes of the mounted shafts, there is no thrust force generated in the axial direction. Also, because of the ease of production, these gears can be made to a high degree of precision. On the other hJasa Hobbing and, spur gears have a disadvantage in that they easily make noise. Generally speaking, when two spur gears are in mesh, the gear with more teeth is called the “gear” and the one with the smaller number of teeth is called the “pinion”.

The unit to indicate the sizes of spur gears is commonly stated, as specified by ISO, to be “module”. In recent years, it is usual to set the pressure angle to 20 degrees. In commercial machinery, it is most common to use a portion of an involute curve as the tooth profile.

Even though not limited to spur gears, profile shifted gears are used when it is necessary to adjust the center distance slightly or to strengthen the gear teeth. They are produced by adjusting the distance between the gear cutting tool called the hobbing tool and the gear in the production stage. When the shift is positive, the bending strength of the gear increases, while a negative shift slightly reduces the center distance. The backlash is the play between the teeth when two gears are meshed and is needed for the smooth rotation of gears. When the backlash is too large, it leads to increased vibration and noise while the backlash that is too small leads to tooth failure due to the lack of lubrication.

All KHK spur gears have an involute tooth shape. In other words, they are involute gears using part of the involute curve as their tooth forms. Looking generally, the involute shape is the most wide-spread gear tooth form due to, among other reasons, the ability to absorb small center distance errors, easily made production tools simplify manufacturing, thick roots of the teeth make it strong, etc. Tooth shape is often described as a specification in drawing of a spur gear as indicated by the height of teeth. In addition to standard full depth teeth, extended addendum and stub tooth profiles exist.

Mesin Hobbing

Hobbing merupakan mesin proses untuk membuat roda gigi , splines , & sprockets di mesin hobbing, yg adalah jenis khusus mesin penggilingan . The Jasa Hobbing teeth or splines are progressively cut inJasa Hobbing to the workpiece by a series of cuts made by a cutting tool called a hob . Gigi atau splines secara progresif pangkas menjadi benda kerja menggunakan serangkaian luka yg dibuat oleh pahat yang diklaim sebuah kompor. Comparedto other gear forming processes it is relatively inexpensive but stillquite accurate, thus it is used for a broad range of parts andquantities. [ 1 ]Dibandingkan dengan proses alat-alat lainnya membangun relatif murahtapi masih relatif seksama, sehingga dipakai buat banyak sekali suku cadangdan kuantitas. [1] It is the most widely used gear cutting process for creating spur and helical gears [ 2 ] and more gears are cut by hobbing than any other process since it is relatively quick and inexpensive. [ tiga ] Ini adalah proses gigi yg paling poly dipakai buat menciptakan pemotongan memacu & roda gigi heliks [2] dan roda gigi lebih dipotong sang hobbing daripada proses lainnya lantaran relatif cepat dan murah. [tiga]Proses

Hobbing uses a hobbing machine with two skew spindles , one mounted with a blank workpiece and the other with the hob. Hobbing menggunakan mesin hobbing menggunakan 2 condong spindle , satu terpasang dengan benda kerja kosong & yang lainnya menggunakan kompor. The angle between the hob’s spindle and the workpiece’s spindle varies, depending on the type of product being produced. Sudut antara poros kompor & poros benda kerja yg bervariasi, tergantung pada jenis produk yang didapatkan. For example, if a spur gear is being produced, then the hob is angled equal to the helix angleof the hob; if a helical gear is being produced then the angle must beincreased by the same amount as the helix angle of the helical gear. [ 4 ]The two shafts are rotated at a proportional ratio, which determinesthe number of teeth on the blank; for example, if the gear ratio is 40:1the hob rotates 40 times to each turn of the blank, which produces 40teeth in the blank. Sebagai contoh, bila gigi pacu yg diproduksi, maka kompor tadi siku sama menggunakan sudut heliksdari kompor, apabila gigi heliks yg diproduksi kemudian sudut harusditingkatkan dengan jumlah yang sama menjadi sudut heliks dalam gigiheliks . [4]Dua poros yang diputar dalam rasio proporsional, yang memilih jumlahgigi dalam kosong, misalnya, jika rasio gigi merupakan 40:1 kompor berputar40 kali buat setiap pergantian kosong, yg menghasilkan 40 gigi dalamkosong. Notethat the previous example only holds true for a single threaded hob; ifthe hob has multiple threads then the speed ratio must be multiplied bythe number of threads on the hob. [ 5 ] The hob is then fed up into workpiece until the correct tooth depth is obtained.Perhatikan bahwa model sebelumnya hanya berlaku buat kompor berulirtunggal;. apabila kompor memiliki beberapa thread maka rasio kecepatanharus dikalikan menggunakan jumlah thread pada atas kompor [lima] kompor tersebut kemudian muak ke benda kerja sampai sahih kedalaman gigi diperoleh. Finally the hob is fed into the workpiece parallel to the blank’s axis of rotation. [ 4 ] Akhirnya kompor dimasukkan ke dalam paralel benda kerja dengan sumbu kosong dari rotasi. [4] Up to five teeth can be cut into the workpiece at the same time. [ 3 ] Oftentimes multiple gears are cut at the same time. [ 5 ] Sampai menggunakan 5 gigi bisa dipotong sebagai benda kerja dalam saat yang sama. [3] Sering kali beberapa roda gigi dipotong dalam ketika yg sama. [lima] For larger gears the blank is usually gashed to the rough shape to make hobbing easier. Untuk gigi yang lebih besarkosong umumnya gashed menggunakan bentuk kasar buat membuat hobbing lebih gampang.Peralatan

Modern hobbing machines, also known as hobbers, are fully automated machines that come in many sizes, because theyneed to be able to produce anything from tiny instrument gears up to Jasa Hobbing 10ft (3.0 m) diameter marine gears. Mesin hobbing modern, pula dikenal menjadi hobbers,merupakan mesin otomatis sepenuhnya yang tiba pada aneka macam berukuran,karena mereka harus sanggup buat membentuk sesuatu menurut gigi instrumenkecil sampai 10 ft (tiga,0 m) roda gigi diameter bahari. Each gear hobbing machine typically consists of a chuck and tailstock , to hold the workpiece or a spindle, a spindle on which the hob is mounted, and a drive motor. [ 3 ] Setiap mesin hobbing gigi umumnya terdiri berdasarkan chuck dan tailstock , buat memegang benda kerja atau gelendong, sebuah spindle yg kompor telah terpasang, & motor drive.

Untuk profil gigi yangmerupakan sukar teoritis, rak dasar lurus-sisi, dengan sisi miring padasudut tekanan berdasarkan bentuk gigi, dengan rata atas & bawah. The necessary addendum correctionto allow the use of small-numbered pinions can either be obtained bysuitable modification of this rack to a cycloidal form at the tips, orby hobbing at other than the theoretical pitch circle diameter. Yang diperlukan koreksi tambahanuntuk memungkinkan penggunaan kepaknya kecil bernomor baik dapatdiperoleh menggunakan modifikasi sesuai dari rak ini buat bentuk cycloidaldi ujung, atau dengan hobbing pada lain menurut diameter lingkaran lapanganteoritis. Since the gear ratiobetween hob and blank is fixed, the resulting gear will have thecorrect pitch on the pitch circle, but the tooth thickness will not beequal to the space width. Karena rasio roda gigiantara kompor & kosong adalah permanen, gigi yg dihasilkan akanmemiliki nada yang benar pada bundar pitch, namun ketebalan gigitidak akan sama dengan lebar ruang. Hobbing machines are characterised by the largest module or pitch diameter it can generate. Mesin hobbing dicirikan oleh terbesar modul atau diameter lapangan bisa membuat. Forexample, a 10 in (250 mm) capacity machine can generate gears with a 10in pitch diameter and usually a maximum of a 10 in face width.Sebagai contoh, mesin kapasitas 10 di (250 mm) dapat membentuk gigidengan diameter 10 pitch & umumnya maksimum 10 lebar paras. Most hobbing machines are vertical hobbers, which means the blank is mounted vertically. Mesin hobbing Kebanyakan hobbers vertikal, yang berarti kosong dipasang secara vertikal. Horizontal hobbing machines are usually used for cutting longer workpieces; ie cutting splines on the end of a shaft. [ 6 ] Mesin hobbing horizontal umumnya digunakan buat memotong benda kerja lagi;.

Chemical Machining: Working Principle, Application & Advantages

In this post, you learn what is chemical machining and why it is used. Also chemical machining working principle, processes, advantages and applications.Chemical Machining

What is the chemical machining?

Chemical machining is the material removal process for the production of desired shapes and dimensions. It is done by selective or overall removal of material by a controlled chemical attack with acids or alkalies.

The metal is slowly converted into metallic salt by chemical reaction and is finally removed in this form. Areas Jasa Machining Medan from where the material is not to be removed are protected by an etching resistant material, known as ‘maskant or ‘resist’.

Almost all the materials, from metals to ceramics, can be chemically machined. The component to be machined is first cleaned in trichloroethylene vapour or in a solution of mild alkaline solution at 80 to 90 °C, followed by washing in clean water.

One of the roughest methods is to coat the component all over by spraying or dipping. This removes dust and oil. The cleaning ensures good adhesion of the coating or masking agent.

After cleaning the component is dried and coated with the maskant material which may be cut and peel, photoresist or screen-print, type. Finally, the metal is removed by etching.

The chemical machining working principle is chemical etching. The part of the workpiece whose material is to be removed is exposed to a chemical known as enchant. The enchantment removes the metal from the chemical attack. The method of making contact of material by the enchant is masking.Chemical Machining Process

The process can be applied to different types of operations such as milling, blanking, and engraving. The different chemical machining processes can be classified as:Chemical millingChemical blankingChemical engraving

Chemical machining for some special purposes can also be achieved by using a jet of reactive gas, e.g., chlorine on the machining zone. This is known as Gaseous Chemical Machining or Hot Chlorine Machining and can be used for deburring of metal parts.Chemical Milling

Chemical milling sometimes called Chem milling or contour machining or etching. It is used to produce shapes by selective or overall removal of metal parts from relatively large surface areas.

The main purpose is to achieve shallow but complex profiles, reduction in weight by removing unwanted material from the surface as in the skin of an aircraft. The components are cleaned and degreased by immersion in trichloroethylene vapour. Or some alternative chemical cleaner followed by washing in clean water.

The component is then coated with a cut and peel maskant by brushing, dipping or spraying (up to 0.dua mm). This can be a suitable fluid with a neoprene base. Or some alternative plastics solution impervious to the action of the etching agent (permitting etching depths up to 10 mm).

When this has dried, by mild heating otherwise, the desired shape to be processed on the work material is cut on the maskant with a scribing knife and the unmachined portions of the maskant are peeled away. Usually, a template is used to portray. The desired machining shape within tolerance.

The parts are then dipped completely into a tank of chemicals which will dissolve (etch) away from the exposed metal. After etching to the required depth, and washing to remove all traces of the etchant, the entire masking is stripped from the component and their surfaces are anodised or treated with a temporary protective agent as necessary.Chemical Blanking

Chemical blanking, chem-blanking, photo forming, photofabrication or photo etching is a variation of chemical milling. In this process, the material is completely removed from several areas by chemical action. The process is used chiefly on their sheets and foils. Almost any metal can be worked by this process, however, it is not recommended for material thinner than 2 mm.

The workpiece is cleaned, degreased and pickled by acid or alkalis. The cleaned metal is dried and photoresist material is applied to the workpiece by dipping, whirl coating or spraying. It is then dried and cured. The method of photography has been used to produce etchant resistant images in photoresist materials.

This type of maskant is sensitive to light of a particular frequency, normally ultraviolet light, and not to room light. This surface is now exposed to the light through the negative i.e., a photographic plate of the required Jasa Machining design, just as in developing pictures. After exposure, the image is developed. The unexposed portions are separated out during the developing process showing the bare metal.

The used metal is next placed into a machine which sprays it with a chemical etchant, or it is drawn into the solution. The etching solution may be hydrofluoric acid (for titanium), or one of several other chemicals. After 1 to 15 min, the unwanted metal has been eaten away, and the finished part is ready for immediate rinsing to remove the etchant.

Printed circuit cards, other engraving operations and blanking of intricate designs can be suitably made by chemical blanking by using photoresist maskants.Very thin metal (0.005 mm) can be well etched.High accuracy of the order of +0.015 mm can be maintained.High production rate can be met by using an automatic photographic technique.Application of Chemical MachiningCHM has been applied in a number of usages where the depth of metal removal is crucial to a few microns, and the tolerances are close. The surface finish obtained in the process is in the range of 0.5 to 2 microns. Besides, it removes metal from a portion of the entire surface of formed or irregularly shaped parts such as forgings, castings, extrusions or formed wrought stock. One of the major applications of chemical machining is in the manufacture of burr-free, intricate stampings. Advantages and Disadvantages of Chemical MachiningThe advantages are that this process does not distort the workpiece, does not produce burrs, and can easily be used on the most difficult-to-machine materials. However, the process is slow, and thus it is not usually used to produce large quantities or to machine material thicker than dua mm. Some small parts are made 10 to 100 at a time on a single plate, which speeds up production.

That’s it. Thanks for reading if you Jasa Machining Medan have any questions about “chemical machining” ask in the comments. If you found this post helpful then please share with your friends.

Mikron Tool


The era of the founders and pioneers

Maschinenfabrik Mikron AG was founded in the Swiss town of Biel in 1908. In the first half of the last century, Mikron played a key role in the industrialization of the Swiss watchmaking industry with Jasa Hobbing its gear-cutting machines and tools.

1908On April 20, the watch manufacturer Karl Lüthy established Maschinenfabrik Mikron AG in Biel/Bienne by taking over Henri Hauser’s mechanical workshop, which had a staff of 35. As the first Managing Director of his factory, he chose Marc Woiblet.

1909Woiblet called in William Dubois, a gifted technician and designer, to assist him. Both men shared a passion for the watchmaking industry and precision engineering. Entirely in keeping with the Swiss tradition of watchmaking, they dedicated themselves heart and soul to precision.

1912 Mikron presented its first gear hobbing machine and the first hob for cycloid tooth forms – pioneering achievements indeed.

1921Mikron launched the first universal gear cutting machine on the market. For the first time, this product enabled the firm to tap a broad-based class of customers, including some outside the watchmaking industry.

1935The then Managing Director, Marc Woiblet, became Chairman of the Board and William Dubois was appointed as the new Managing Director one year later. The ensuing period saw the continued development of machines and tools.

1938Mikron introduced its first pension plan for employees.

1954William Dubois died and the technical development within the firm was “orphaned” and the era of the founders and pioneers was drawing to a close.

1956In a period of economic upturn, Mikron established a significant expansion of production capacity.

1958A deep recession began. Despite great privations, Mikron had survived two world wars and the intervening economic crises unscathed, so it would also be able to pass this new acid test.


Expansion and diversification

From 1960 onwards, Mikron gradually expanded its activities into new areas, such as milling machines, plastic components, and machining systems.

1961Mikron launched an extensive development programme lasting several years and encompassing every area of the firm, with the advent of new technical developments, expanded production capacity and a modernized organization. This was the start of an era of expansion and diversification.

1961The new established Mikron Holding AG acquired Maschinenfabrik Mikron AG as its first subsidiary.

1962On January 1, Mikron acquired Haesler SA of Boudry, Switzerland, the producer of transfer machines. In the same year Mikron stopped producing bench lathes, ébauche machines and milling machines, and invested in an electro-erosion department to manufacture milling cutters and, later on, injection molds.

1963Mikron took over J. Goulder & Sons Ltd. of Huddersfield, UK, a manufacturer of gear testing machines which was renamed Goulder Mikron. The same year saw the establishment of the company’s own pension fund in which white- and blue-collar employees were given equal status in all respects. The reorganization of the pension scheme also led to the introduction of monthly pay for all employees.

1965The first series-produced transfer machine contoh was manufactured.

1966Mikron resumed its traditional manufacture of milling machines with the launch of a new generation of universal tool milling machines.

1970As metal gearwheels were replaced by plastic versions, the firm opened its Plastics Department and began producing plastic parts. The preceding years had seen increasingly frequent requests from major customers for finished injection-molded parts instead of the injection molds that the firm supplied.

1976The primary assembly system based on the rotary indexing technology is launched: the Polyfactor™.

1977Marked the launch of Mikron’s first assembly machine, as a reaction to the increasing automation of industry in general and declining sales in the watchmaking industry.

1978Mikron US Corporation was established as a sales company at South Norwalk, CT/USA. Four years later, it relocated to Monroe, CT/USA and became a production facility.

1983Mikron became a 100% public corporation with the public placement of the majority package of registered shares by the Gasser family.

1986 – 1996

In 1986 Mikron acquired Albe SA of Agno, Switzerland, together with its sales branch in Tokyo, Japan. This was a step towards strategic growth which made Mikron the world’s most important manufacturer of machining systems in a specific application area.

1986Mikron acquired Albe SA of Agno, Switzerland, together with its sales branch in Tokyo, Japan. This was a step towards strategic growth which made Mikron the world’s most important manufacturer of machining systems in a specific application area.

1986Mikron started operations with a strategic partner (today Swisstec) in China.

1987Marked the start of a focused reorientation of the Machining and Assembly Systems division that was to last several years: the range was streamlined, new developments were pushed forward and the production of machining systems was concentrated in Agno.

1988Manufacturing of the Multifactor™ machining systems moved from Mikron SA Boudry, Switzerland, to Agno. Launch of the PM-30 rotary indexing machine.

1989Saw the market launch of Mikron’s first machining centre, in cooperation with Beaver Engineering Group plc, of the UK. The same year marked the start of an extensive three-year investment programme intended to enable Mikron to exploit its potential in view of forthcoming changes.

1990 Establishment of Mikron GmbH Rottweil (Germany) as a sales and service company. Launch of the Multistar™ LX-24 machining system for the writing instrument industry.

1990On June 27 an attempted hostile takeover by a group of shareholders headed by the financier Werner Fleischmann was warded off at an Extraordinary General Meeting, bringing a nine-month defensive campaign to an end.

1991 Mikron SA Agno concentrated its activities on the transfer machine field. Creation of the Machining Technology Division. Launch of the Multistar™ CX-24 machining system.

1992 Launch of the Multistar™ LX-24 machining system for industrial applications beyond the writing instrument industry.

1993 Launch of the Multistep™ machining system.

1994Development of the linear assembly solution Flexifactor™, a concept based on the standard Flexcell™ cell.

1995Following the economic crisis between 1991 and 1993 the Millling Machines division was Jasa Hobbing about to enter into a strategic alliance. The other three divisions were in very good shape.

Lima Reasons To Keep Machining Coolant Clean

Dirty metalworkJasa Machining ing fluid can cause a host of problems for your CNC machining operation and can be harmful to machinists—if not cared for properly. Here are the top reasons for keeping your coolant and filters clean and maintained—with advice on how to manage it. Jasa Machining Medan

Most machinists would agree that a properly mixed, high-quality cutting fluid does smell quite pleasant. But if it is not maintained or cleaned, after awhile, cutting fluid can stink. Give it a couple of Jasa Machining Medan weeks of neglect and the Monday morning stench is enough to make even the most olfactory-challenged machinist yearn for the weekend. If the assault on your nose isn’t bad enough, however, rancid coolant is hard on other things too, starting with your health—and can negatively affect tool and machine life, finishes and a host of other key metalworking processes and parts.

Here are a few pointers you should keep in mind if you’re to optimize productivity while protecting the shop’s most important assets: its workers.Machining Coolant Can Cause Rashes and Dermatitis

To be fair, even freshly mixed cutting fluids contain a host of chemical additives such as biocides, emulsifiers, corrosion inhibitors, anti-foaming agents and more, any of which can cause skin irritation, rashes and dermatitis. When cutting fluid is neglected, the concentration of these chemicals may reach unsafe conditions. Also, an improperly maintained machine tool sump becomes a perfect breeding ground for microbes.

“At low concentrations bacteria can grow unimpeded in the sump and cause pH of the coolant to drop and cause rust,” says John Treese, director of global pelatihan at Master Fluid Solutions. “Low concentration [of fluid] can grow bacteria that can aggravate skin issues including simple cuts and scratches. High concentration adds too much chemical that can do the same.”

Aside from creating noxious odors and degrading coolant, these microorganisms—when combined with tiny skin abrasions—can hasten the chance of infection. “Microabrasions,” as they are known in the industry, happen when extremely fine chips and swarf reside in dirty coolant, not so much the larger chips we see flying off the workpiece during the cutting process, explains Jim Brumgard, an application engineer in Castrol’s industrial division.

“Of course, big chips can cause cuts, but that type of cut usually requires first aid,”  says Brumgard. “The skin abrasions occur when there is coolant splashed onto the skin and then the operator wipes away the dirty coolant … These often microscopic tiny fines will cause the scratches as the towel or rag is wiping them across the skin.” 

They are usually recognized as irritated skin, but what has happened is these tiny cuts have allowed the coolant to cause even more irritation due to broken skin. Bottom line: The dirty coolant has become abrasive to the skin and leaves it more susceptible to irritation, Brumgard asserts. 

That’s why coolant should be treated with respect. Wash hands regularly with a mild, nonabrasive soap. Use a moisturizer to create a protective skin barrier that slows the absorption of chemical additives. Wear thin nitrile gloves if practical (though never wear heavy gloves around machinery). Keep clothing clean and dry. And avoid using solvents to clean parts, as these eliminate the natural oils on our skin, leaving it unprotected.

Understanding The Elements: The Coordination Of Materials, Coatings And Geometry

Process Insights

Key To High-Speed Aluminum Machining

Technological developments such as the Makino MAG-Series machines have made tooling vendors rethink the core concepts of their tooling designs. To get the most out of any state-of-the-art machine technology, it is penting to apply the right tooling and programming concepts.

The primary tooling concerns when machining aluminum are: minimizing the tendency of aluminum to stick to the tool cutting edges; ensuring there is good chip evacuation from the cutting edge; and ensuring the core strength of the tool is sufficient to withstand the cutting forces without breaking.

Materials, coatings and geometry are the three elements in tool design that interrelate to minimize these concerns. If these three elements do not work together, successful high-speed milling is not possible. It is imperative to understand all three of these elements in order to be successful in the high-speed machining of aluminum.

Minimizing the Built-Up Edge

When machining aluminum, one of the major failure modes of cutting tools is the material being machined adheres to the tool cutting Jasa Machining Medan edge. This condition rapidly degrades the cutting ability of the tool. The built-up edge that is generated by the adhering aluminum dulls the tool so it can no longer cut through the material. Tool material selection and tool coating selection are the two primary techniques used by tool designers to reduce the occurrence of the built-up edge.

Two different carbide materials used in high-speed machining tools are sub-micron grain and course grain. Sub-micron grain carbide material has generally been accepted as the preferred material of choice because it is very hard and Jasa Machining maintains a sharp cutting edge. When machining aluminum at very high speeds, however, this conventional wisdom is incorrect.

The sub-micron grain carbide material requires a high cobalt concentration to achieve the fine grain structure and the material’s strength properties. Cobalt reacts with aluminum at elevated temperatures, which causes the aluminum to chemically bond to the exposed cobalt of the tool material. Once the aluminum starts to adhere to the tool, it quickly forms a built-up edge on the tool rendering it ineffective.

The secret is to find the right balance of cobalt to provide adequate material strength, while minimizing the exposed cobalt in the tool for aluminum adherence during the cutting process. This balance is achieved using coarse-grained carbide that provides a tool of sufficient hardness so as to not dull quickly when machining aluminum while minimizing adherence.

Tool Coatings

The second tool design element that must be considered when trying to minimize the built-up edge is the tool coating. Tool coating choices include TiN, TiCN, TiAIN, AlTiN, chrome nitrides, zirconium nitrides, diamond and diamond-like coatings (DLC). With so many choices, aerospace milling shops need to know which one works best in an aluminum high-speed machining application.

The Physical Vapor Deposition (PVD) coating application process on TiN, TiCN, TiAIN, and AlTiN tools makes them unsuitable for an aluminum application. The PVD coating process creates two modes for aluminum to bond to the tool—the surface roughness and the chemical reactivity between the aluminum and the tool coating.

The PVD process results in a surface that is rougher than the substrate material to which it is applied. The surface “peaks and valleys” created by this process causes aluminum to rapidly collect in the valleys on the tool. In addition, the PVD coating is chemically reactive to the aluminum due to its metallic crystal and ionic crystal features. A TiAIN coating actually contains aluminum, which easily bonds with a cutting surface of the same material. The surface roughness and chemical reactivity attributes will cause the tool and work piece to stick together, thus creating the built-up edge.

In testing performed by OSG Tap and Die, it was discovered that when machining aluminum at very high speeds, the performance of an uncoated coarse-grained carbide tool was superior to that of one coated with Tin, Ticn, TiAlN, or ALTiN.

This testing does not mean that all tool coatings will reduce the tool performance. The diamond and DLC coatings result in a very smooth chemically inert surface. These coatings have been found to significantly improve tool life when cutting aluminum materials.

The diamond coatings were found to be the best performing coatings, but there is a considerable cost related to this type of coating. The DLC coatings provide the best cost for performance value, adding about 20 percent to 25 percent to the total tool cost. But, this coating extends the tool life significantly as compared to an uncoated coarse-grained carbide tool.


The rule of thumb for high-speed aluminum machining tooling designs is to maximize space for chip evacuation. This is because aluminum is a very soft material, and the feedrate is usually increased which creates more and bigger chips.

The Makino MAG-Series aerospace milling machines, such as the MAG4, require an additional consideration for tool geometry—tool strength. The MAG-Series machines with their powerful 80-HP spindles will snap the tools if they are not designed with sufficient core strength.

On previous technology, the number of flutes on the tool had to be increased to provide the proper chip load at speeds required to achieve high quality cuts in aluminum. With the 30,000-RPM and the 80-HP spindle technology, the number of tool flutes must be reduced and the core strength of the tool increased.

The high RPM capability of the spindle will ensure the proper chip load and the strong core tool strength. This enables the entire 80-HP to cut metal without fear of tool breakage. In detailed testing outlined later, it was discovered that a two-flute tool provided the best geometry for chip evacuation and tool strength.

In general, sharp cutting edges should always be used to avoid aluminum Jasa Machining Medan elongation. A sharp cutting edge will create high shearing and also high surface clearance, creating a better surface finish and minimizing chatter or surface vibration. The issue is that it is possible to achieve a sharper cutting edge with the fine-grained carbide material than the coarse grained material. But due to aluminum adherence to the fine-grained material, it is not possible to maintain that edge for very long.

The coarse grained material appears to be the best compromise. It is a strong material that can have a reasonable cutting edge. Test results show it is able to achieve a very long tool life with good surface finish. The maintenance of the cutting edge is improved using an oil mist coolant through the tool. Misting gradually cools down the tools, eliminating thermal shock problems.

The helix angle is an additional tool geometry consideration. Traditionally when machining aluminum a tool with a high helix angle has been used. A high helix angle lifts the chip away from the part more quickly, but increases the friction and heat generated as a result of the cutting action. A high helix angle is typically used on a tool with a higher number of flutes to quickly evacuate the chip from the part.

When machining aluminum at very high speeds the heat created by the increased friction may cause the chips to weld to the tool. In addition, a cutting surface with a high helix angle will chip more rapidly than a tool with a low helix angle.

A tool design that utilizes only two flutes enables both a low helix angle and sufficient chip evacuation area. This is the approach that has proven to be the most successful in extensive testing performed by OSG when developing the new tooling line, the MAX AL.

Tale of the Test

OSG has extensively tested the new tooling line, MAX AL on the Makino MAG4, which was developed and tested concurrently with the release of the MAG4. The MAX AL tool is designed for higher spindle speeds and a higher feedrate.

OSG created a corner radius, two-flute design with a K-grade or course-grain carbide. This creates high rigidity and a thick core without sacrificing chip capacity. And it works under the most severe conditions.

This tool achieved impressive performance with respect to metal removal rate and tool life cutting of a wing rib part. The wing rib has general dimensions of 2000 mm-x 500 mm x 2000 mm. A 0.750-inch diameter MAX AL tool with through-coolant mist was used at 21,500 rpm and a feedrate of 394 inches per minute (ipm), and a .68-inch depth of cut, 90 percent of the tool diameter.
