Pass MaxiDrill 900, dark pulled expert of climate hard alloy to develop a new cutting tool concept, diametical limits is 63mm of 12 ～ , length is as high as 5 times diameter, periphery and center use identical chamfer model, dimension and brand. Can simplify so use, avoid to use a fault and improve efficiency. Pass MaxiDrill 900, dark pulled expert of climate hard alloy to develop a new cutting tool concept, diametical limits is 63mm of 12 ～ , length is as high as 5 times diameter, periphery and center use identical chamfer model, dimension and brand. Can simplify so use, avoid to use a fault and improve efficiency. Bore is one of common treatment methods. But the pronoun that the broach of dislocation razor blade makes tall cutting function and economy below this kind of condition, these elements decided efficient production whether make the enterprise gains a success in the market with current intense competition. 3% what cutting tool cost holds whole production cost only, but finished cost and cost of the time that change a knife are occupied quite the 25% ～ of portion 30% , those who reduced the scale of these cost to become implementation to improve productivity apparently is important one pace. Dark pulled climate to provide a cutting tool system in hypostatic material bore through the MaxiDrill 900 that roll out, its design profit from distinctly, can use CTPP430 of brand of tall union hard alloy, maxiDrill 900 ensures high-powered with cutting tool life, raise manufacturing efficiency and the safety that produce a course to reduce machine tool machine down time. Operate handy and clever design, simplified to produce the operation in the process, periphery and the razor blade with central identical reoccupy, this is a huge advantage, because the fault won't be installed in actual unit process of cargo bandling, can reduce content shedding and inventory at the same time. New name, chamfer it is very important to will be told with coating to bit. Dark drawing climate circle is well-known in in the light of wear-resisting differentiate with industry of product of material of cutting tool horniness and innovate continuously the global market leader of the respect, having extensive experience and knowledge for this, the effectiveness that this one advantage can ensure cutting tool is designed and high-powered. However, handlers must know the characteristic of the product and the high-powered benefit from cutting tool, if function is identical and OK,reduce brand sort, the client can gain more benefit. Reduce name amount to be this, dark pulled climate to optimize a brand, roll out a current name. Brand CTPP430 has extremely tall wearability and outstanding tenacity, its application range is wide model, can suit all getting to cut application almost. For example, it can be used at high speed intermittent auger cut, can get cut cast crustaceous with difficult operating mode (convex or) of oblique plane bore, be machined material can be cast-iron, nonferrous metal and steel, stainless steel, difficult treatment material. The test example that uses actually gets actually cut test test and verify this one theory: The wearability with profit from outstanding razor blade () of 4 cutting point, maxiDrill 900 cutting tool is had in the bore of hypostatic material relatively longer cutting tool life, because this is in,efficiency improved for long in treatment. MaxiDrill 900 cooperates CTPP430 brand, the igneous wheel that processes temper steel (1050N/mm2) of ～ of intensity 900 had apparent ground to rise: Cutting speed from 180 raise 200m/min, feed rate rose 33% . Amount of the treatment in same time from 150 increase 198 opening, wear extent is lower at the same time. CNC MillingCNC Machining
