Compare the fast steel with pulverous a lot of taller metal through using cutting rate, can improve manufacturing efficiency 30% above: Material of a kind of new-style cutting rolling mill is had already taller be able to bear or endure lukewarm ability, do not lose its tenacity again at the same time, because this can satisfy the requirement of this respect. In current economy prosperity and the environment that demand increases fall, competitive pressure is increased ceaselessly, because this need optimizes pull current Cheng further. Place of research and development of new technology of company of LMT of no less than makes clear, accurate tool is acting an important role in this respect. This company continues on the foundation of compound cutting material research and development gives new generation monomer to roll milling cutter. Had this kind of cutting tool, the user can improve existing manufacturing efficiency again 30% above, carry the technological process that optimizes gear cutting further at the same time, continue to hold the competitive dominant position of the enterprise for a long time. Material of this kind of new-style cutting rolling mill is called Speedcore. The core feature of this material rolling mill is to have taller be able to bear or endure lukewarm ability. The high-speed steel that makes with pulverous metal (PM-HSS) photograph comparing, the cutting rate when material of this kind of cutting is rolling mill can rise greatly most 50% . This kind rolls milling cutter to deserve to wait for efficient coating with such as LMT Nanosphere with what Speedcore is a foundation, can bring greater manufacturing benefit for the user. The profit that higher cutting rate brings to the user is self-evident, because the user can be on existing manufacturing facilities,this is treatment is compared before more components. Had new-style cutting stuff, LMT Fette company can continue to advance its to work in the equipment system research and development of gear cutting respect. Rolling respect of milling cutter system, besides coating and cutting material, still the technical project according to user demand and service project also not allow to ignore, safeguard in the whole world of Germany, United States and Chinese and other places for example with coating network. Higher cutting rate and longer cutting journey are the dominant position of the foundation that rolls milling cutter to be able to see from first test result with new-style cutting material. First-run test supports next undertaking by what LMT company is in Magdeburg university. In experiment process, speedcore rolls milling cutter to be able to achieve hard metal almost completely to roll the capacity limits that milling cutter place withholds. In the test of tornado milling cutter that does on actual part, when cutting speed achieves 350m/min, cutting journey still can achieve 7m above, and edge carries a phenomenon without overheat. To it contrary, a PM-HSS rolls milling cutter to encounter below the cutting speed of 280m/min its heat up load limit, the journey shortened apparently about 3m. The experiment of university of graph 1 Magdeburg to LMT Speedcore material: Below 350m/min cutting speed, cutting journey still can achieve 7m above to real work character, these experiments make clear: Insert tine journey in the light of 10m, the user can raise cutting rate at least 30% , and won't affect manufacturing security issue. The actual check test and verify that follow-up of no less than does is solid, this kind of character also matters to the economic benefits of the enterprise directly. Use modulus 2.

5 rolled steel make gear and tine number is for 28 tine and facewidth 37.

The user of 5mm is OK raise cutting rate on existing technology base 30% . Nextpage pursues the 2 bases that reached 30% higher cutting rate to roll milling cutter in real test are new-style cutting material. This kind of material is mixed by cobaltic, molybdenum not carbonaceous steel is formed. Combination of this kind of material is below the premise that does not affect material tenacity, can make the heat-resisting function of cutting material than the PM-HSS base material at the tradition more remarkable rise. To this, heat treatment flow is crucial. The heat treatment that groovy PM-HSS cutting material issues in the first 1200 ℃ is changed by austenite in flow. Right now, the carbonization metal of tall alloy is decomposed namely. To avoid grain excessive growth, need to cool material to 500 ℃ then the following. Gets material organization structure is the martensite, primary carbide that did not decompose, grain limit carbide and odd austenite material. Be changed to make the constituent structure divide evenly of material qualitative and reduce the content of odd austenite material, have temper for many times to HSS material. Through choosing temper temperature, decide sub hardness, in order to achieve the application characteristics that place needs in the future. The biggest use temperature also is by limitation under about 500 ℃ . In follow-up coating work, this temperature limit also must not be exceeded. Graph the small structure of 3 PM-HSS material: The martensite steel after temper, the hardness that handles cutting material through the sub sclerosis of carbide phase is moved to 65~68HRC limits new-style cutting material needs to accept heat treatment twice only. Begin temper process directly after austenite is changed. Cutting material undertakes separate out sclerosis through building accept rice structure, namely the metal is compound process. The hardness of cutting material can is in by set 65~68HRC limits. In safeguard a respect, material of this kind of cutting also has an advantage. When hard metal rolls milling cutter to be broken away from in coating, the cobaltic component inside is by the danger of separate out, cause cutting tool to become thereby 1000 sore 100 aperture; And Speedcore cutting data won't appear when coating is broken away from problem, very easy also by repair. The small structure of material of graph 4 Speedcore: The martensite steel after temper, through the metal the hardness of the material of cutting of sub and sclerotic processing of complex phase is moved to 65~68HRC limits new-style cutting material needs to accept heat treatment twice only. Begin temper process directly after austenite is changed. Cutting material undertakes separate out sclerosis through building accept rice structure, namely the metal is compound process. The hardness of cutting material can is in by set 65~68HRC limits. In safeguard a respect, material of this kind of cutting also has an advantage. When hard metal rolls milling cutter to be broken away from in coating, the cobaltic component inside is by the danger of separate out, cause cutting tool to become thereby 1000 sore 100 aperture; And Speedcore cutting data won't appear when coating is broken away from problem, very easy also by repair. The place on put together is narrated, new-style cutting material still has other dominant position, it can improve LMT cutting tool and the process capability of system rolling mill further. Because the thermal stability of material is better now, because this also can raise such as milling cutter,making the temperature when coating is handled. Such, coating also can accord with the need that uses an occasion individually more. This enterprise values LMT-Fette new material to roll the market opportunity of milling cutter quite. In the future, the one form of characters or letters that will 30% above are a foundation with this rolls city of milling cutter face and will replace PM-HSS to roll milling cutter stage by stage.
