Head of ball of Impact Miracle special coating establishs milling cutter set is 3 water chestnut of Japanese the head of ball of high-powered whole type that company of tool of hard alloy of comprehensive data group develops stands milling cutter, the article is as follows to brief introduction of its cutting function. The characteristic that head of special coating ball stands milling cutter (1) coating material is special coating is will original be used at tall hardness treatment (Al, ti, si) the structure of single crystal photograph of N coating undertakes accept rice class changes crystallization imperceptibly, make its hardness achieves Hv3700, begin oxidation temperature to raise 1300 ℃ , improved its wear-resisting and heat-resisting performance substantially, reduced coefficient of friction of its high temperature at the same time, treatment precision and exterior surface roughness also were obtained rise significantly. (2) coating of hard alloy base material is great to improving function of cutting tool life, but to different workpiece material and treatment status, to develop coating property adequately, the performance that improves cutting tool base material is crucial. From this kind the viewpoint sets out, company of 3 water chestnut developed the hard alloy base material that suits to be mixed to machine condition by treatment material, for example: Head of ball of VF-2SB double blade stood milling cutter to use wear-resisting function to exceed fine grained hard alloy exceedingly goodly; VF-2SDB is puissant model head of double blade ball stood milling cutter to use what can improve performance of the blade that fight collapse considerably to exceed fine grained hard alloy. (3) head of ball of Shuang Ren of VF-2SB of ① of cutting blade appearance stands milling cutter: This is function of a kind of wear-resisting exceedingly good, fit stuff of milling tall hardness establish milling cutter, cutting blade appearance used the part before losing, r precision is ± 5 μ M, external diameter precision 10 μ of 0 ～ M, precision of petiole external diameter amounts to H5. Because used the special coating with wear-resisting and heat-resisting superior performance, because this can maintain very tall treatment precision for long. ② VF-2SDB is puissant model head of double blade ball stands milling cutter: In late pattern antrum, big feed, big in cutting function of deep, wear-resisting to ask very tall mould is machined, the treatment condition such as parameter of contrail of motion of treatment appearance, cutting tool, cutting is changing ceaselessly, the cutting treatment difficulty that should realize stability is very great, also can appear sometimes the case that cannot develop coating property adequately. VF-2SDB establishs the cutting part of milling cutter to be ball head appearance, cut work easily, used can reduce blade of cutting of form of new-style to cutting tool percussive S, the circle outside arriving from ball head center was used what can raise sex of the blade that fight collapse considerably is new-style blade of cutting of the horn before losing. Besides VF-2SB, VF-2SDB, still VF-2XLB Shuang Ren grows neck ball head to establish milling cutter and VF-2SSB hot pressing to cooperate short handle model head of Shuang Ren weak point ball stands milling cutter. The cutting property that head of special coating ball stands milling cutter (1) the high-speed steel of powder of milling of cutting function ① that head of ball of VF-2SB Shuang Ren stands milling cutter is right SKD11 mould steel (hardness is HRC60 about) treatment of high speed milling is increasingly practical already change. But, when the pulverous high-speed steel that exceeds HRC65 to hardness undertakes milling is machined, cutting tool life is very brief, treatment efficiency is very low, because this can use electric spark treatment only mostly. The VF-2SB that uses R1 establishs milling cutter milling to process ASP60 pulverous high-speed steel (HRC69) when (cutting condition: Rotate speed: 8000r/min, speed of the biggest cutting: 18m/min, feed speed: 1260mm/min (0.

08mm/ ages) , arrange mill, air is cold) , the scathing condition that obtains blade of the cutting when 50m when cutting length is knowable, VF-2SB establishs the cutting blade wear extent of milling cutter to be less than the 1/2 of original product of company of 3 water chestnut. From the point of treatment result, as a result of the exceeds fine grained hard alloy result of the function of special coating and new development, raised VF-2SB to establish the wear-resisting property of milling cutter substantially, make its can be competent the milling treatment of the pulverous high-speed steel that hardness exceeds HRC65. Mould of STAVAX of ② milling treatment establishs milling cutter to process the STAVAX data with the commonly used model that note model with the VF-2SB of R3 (HRC52) (cutting condition: Rotate speed: 18000r/min, speed of the biggest cutting: 148m/min, feed speed: 3600mm/min (0.

1mm/ ages) , cutting tool is dangerous extend length: 25mm, arrange mill, air is cold) , when the injury of blade of the cutting when cutting length achieves 340m the state makes clear, with company of 3 water chestnut the cutting tool photograph of company of original product etc is compared, the wear extent of VF-2SB is reduced considerably, can manage R precision and cutting property for long. In recent years, the medium hardness with tall, abrade short time notes requirement treatment precision the treatment of model model is increasing, head of special coating ball stands milling cutter to be able to produce remarkable treatment result. (2) VF-2SDB is puissant model the cutting function of the milling of antrum of late pattern of cutting function ① that head of Shuang Ren ball stands milling cutter is in mould manufacturing industry, plan time to shorten, reduce finished cost, use direct milling to machine means increasingly popular. But in the milling treatment in complex form mould (especially the treatment of late pattern antrum) , change of bear of cutting of susceptive of point of a knife is big, produce collapse blade easily, cutting tool life is not stable, because cutting tool is dangerous,this basically is extend length (long way compares L/D) big, because place of point of a knife decreases quick result to answer, make blade of sharp change, cutting contacts feed speed to length increases and produce high frequency vibration to cause. With R5 (φ 10) VF-2SDB establishs former some of milling cutter and company of 3 water chestnut to be the same as norms cutting tool, in low speed of point of a knife feed, big cut SKD61 of the milling below deep condition (HRC52) when (cutting condition: Rotate speed: 6000r/min, speed of the biggest cutting: 188m/min, feed speed: 500mm/min (0.

042mm/ ages) , cutting tool is dangerous extend length: 70mm, arrange mill, air is cold) , the contrast that fights collapse blade function by cutting tool experiments to be able to see as a result, of original product A most advanced with original product B outside round part produced bigger burst blade; And blade of cutting of the horn before because used S form to lose,VF-2SDB establishs milling cutter and can raise those who fight collapse blade sex to exceed matrix of fine grained hard alloy, did not produce collapse blade. This shows, VF-2SDB fights collapse blade function to exceedingly good, life grows and be stabilized, it is the advanced cutting tool that applies to milling of late pattern antrum. ② big feed (efficient) the cutting function of milling machines efficiency to raise a pattern, can use commonly small the treatment method that cuts deep, big feed. But in be being machined actually, because machine appearance, cutting tool to machine the problem such as orbit, also produce the situation of the treatment effect that because of collapse blade short of hopes constantly. The VF-2SDB ball head that uses R3 stands SKD61 of milling of milling cutter high speed, big feed (HRC52) when (cutting condition: Rotate speed: 12000r/min, speed of the biggest cutting: 226m/min, feed speed: 4500mm/min (Shuang Ren: 0.

18mm/ tine; 3 blade: 0.

12mm/ ages) , cutting tool is dangerous extend length: 35mm, arrange mill, air is cold) , trial work is actual mould, by cut deep figure knowable, overall cutting blade (complete R) all participate in cutting of late pattern antrum. Test result makes clear, of A of other company product outside round place produced collapse damage, the central place of product B produced collapse blade, and VF-2SDB establishs milling cutter to did not produce collapse damage, stabilize treatment the big feed that realized late pattern antrum, macrobian life, efficiently, high.
