In recent years, in to raising a pattern precision is mixed shorten below the situation with the increasingly strict requirement of delivery cycle, raise the treatment precision, necessity that reduces grinding workload as far as possible thorough already popular feeling. For this, the user is badly in need of the milling cutting tool of high accuracy, high quality, macrobian life. Companies of 3 tool of Kobe of water chestnut material developed CBN-2XLB CBN to grow neck ball head to establish milling cutter and VC-2PSB-P high accuracy ball head stands milling cutter. Head of ball of long neck of 1 CBN-2XLB CBN stands milling cutter people hope CBN establishs milling cutter to have two great performance: Although can be machined,① can machine original cutting tool steadily but the tall hardness data with cutting tool short life. 2005, the coating hard alloy that this company unripe produce and sale made work to be able to machine the tall hardness material of HRC60 above, life to exceed original cutting tool establishs milling cutter. But the CBN with user need longer life establishs milling cutter. ② can long mill machines essence of life to wait for material from hard steel. When using small diameter to establish mill of milling cutter essence to machine especially, because cutting tool diameter is lesser, cutting length lengthens, establish milling cutter treatment to often need to use a few cutting tool with original hard alloy. Be aimed at these performance demands, developed CBN-2XLB CBN to grow neck ball head to establish milling cutter. (1) the cutter hub material that CBN-2XLB of milling cutter characteristic CBN grows neck ball head to establish milling cutter is hard alloy, knife clip and cutting blade part are CBN material. Because establish mill treatment to belong to interrupted cutting, should choose the CBN stuff with good performance of high strenth, puissant interrupted cutting. To win high grade precision work face, the platoon bit of part of point of a knife is crucial. The point of a knife of this milling cutter is had enough the big chamfer that hold bit, generation is bitten because of cutting bits and won't injure the circumstance that machines a face; Overall cutting blade is used lose edge, improved cutting blade intensity and performance of the blade that fight collapse; R precision achieves ± 5 μ M, blade of ball head cutting and outside the join of round cutting blade does not have mark glossily, can realize high accuracy milling; The join of CBN and cutter hub uses crimp means, the basis machines need, but unlimited aleatoric lengthen is cervical and the following length. (2) the CBN that example of steel of treatment SKD11 mould inspected to use head of ball of CBN of CBN-2XLB long neck to establish steel of tall hardness of milling cutter, original treatment to establish company of milling cutter etc to produce with coating hard alloy establishs milling cutter to process hard steel of SKD11 temper by dipping in water (HRC60) the cutting tool when wears away parallel case (rotate speed: 20000r/min; Feed speed: 1700mm/min; Cutting fluid: Oily mist) . CBN-2XLB establishs the cutting length of milling cutter to amount to 800m; Coating hard alloy establishs the cutting length of milling cutter to be 200m; Other company CBN establishs the cutting length of milling cutter to be 500m. Coating hard alloy reachs service life because of wearing away; Because blade of cutting blade collapse reachs service life,other company CBN establishs milling cutter. The cutting length that CBN-2XLB establishs milling cutter is 4 times what coating hard alloy establishs milling cutter, it is other company CBN 1 what establish milling cutter.

6 times, but its wear away very small still, held good cutting position. The performance of the blade that fight collapse that because CBN-2XLB establishs milling cutter,establishs milling cutter than other company CBN is good, the wearability that establishs milling cutter than hard alloy at the same time is good, because this is in,treatment shows superior performance when tall hardness material. (3) treatment NAK80 uses CBN-2XLB quite from the finish machining face of hard steel model establish milling cutter and hard alloy to establish milling cutter to machine NAK80 from hard steel when (rotate speed: 40000r/min; Feed speed: 4000mm/min; Cutting fluid: Oily mist) , the treatment circumstance after milling length achieves 2000m makes clear, with milling SKD11 (HRC60) when photograph comparing, two kinds establish milling cutter wear away difference is reduced somewhat, the milling length that this demonstrates to hard alloy establishs milling cutter also can achieve 2000m above. In light of the treatment range pattern after Dan Congxi cuts 2000m, the is equivalent to cutting blade feed knife mark that CBN-2XLB establishs milling cutter is very clear, and the mark of treatment face knife that hard alloy establishs milling cutter is unsharpness, still produced cutting to squeeze even crack. This shows, CBN-2XLB because have superior wear-resisting performance, wait in treatment NAK80 from the can keep for long stable finish machining area when hard steel, what when this machines old plane to using a cutting tool, unmanned value defends is long treatment is very useful. Ball head stands 2 VC-2PSB-P high accuracy milling cutter (1) this company began figure of department of high accuracy blade 2003 the R precision that head of ball of hard alloy of the VC-2PSB of the sale high accuracy stands milling cutter achieves ± 5 μ M. In recent years, be opposite to satisfy more the requirement that head of high accuracy ball establishs milling cutter, developed VC-2PSB-P ball head to establish milling cutter again, its R precision achieves ± 2 μ M, for world highest precision. Its size scope from R0.

05 - R6mm in all 23 kinds of norms. This design that establishs milling cutter values the cutting property of cutting blade appearance very much. General ball head establishs the cutting rate near center of milling cutter point of a knife very low, cutting blade does not remove cutting action to squash however workpiece material, arise thereby crowded crack blemish, because this gains face of high grade treatment hard. The VC-2PSB-P core in was being improved distributes cutting blade form, till central part has good cutting property,realized blade of ball head cutting. In addition, r blade and outside the join of round cutting blade is pliable without mark, can avoid finish machining face thereby not the generation of flatness. (2) can obtain good treatment face to use VC-2PSB-P model (R3mm) milling SKD61 (HRC52) after 50m of mould of hard steel of temper by dipping in water, can see the cutting of clear and visible, periodic feed on face of mill of essence of life trace; As contrary as this, original the surface after establishing mill of milling cutter essence because of cutting blade crowded crack blemish, make periodic feed cuts mark unsharpness. This shows, head of ball of VC-2PSB-P highest precision stands milling cutter to be when hard steel of milling temper by dipping in water, can maintain the cutting blade appearance of high accuracy for long.
