Fraisa is high-powered establish milling cutter to design detail to decide to machine function

The research and development of the geometrical structure of milling cutter and detail craft, often can decide the discretion of product function. In domain of integral milling cutter, the character stand or fall that structure of raw material, coating, geometry and detail technology design decided milling cutter. Fraisa includes essence of alterable helix chamfer, point to grind processing to the design of product detail, defend horn, deepen structure of geometry of form of helix chamfer, chamfer optimize, processing of high spirit of point passivation and knife handle ministry is waited a moment. Of high end of Fraisa base oneself upon establish milling cutter, the treatment domain of its product includes treatment of mould, spare parts, tool to make, medical apparatus and instruments, aerospace, car is made, cycle racing, horological and energy industry. Fraisa is high-powered establish milling cutter to basically promote a product property from a few main fields: Reduce vibration, make cutting point stronger, avoid to stick scrap, rise precision and improve efficiency. Fraisa is high-powered establish milling cutter reducing oscillatory respect, the design that adopts alterable helix chamfer will come true. Between tooth if having same helix point of view and span,produce vibration or resonance easily, the oscillatory meeting with strong cutting tool brings about cutting tool to wear away badly, still can make knife flower increases in addition, bring about thereby acquire bad exterior quality. Accordingly, differ of cent asymmetrical cutting tool, had very big effect to reducing resonance. Because reduce vibration, can get better exterior quality, still added cutting tool life, reduced a machine tool to wear away. Fraisa is special use design of chamfer of alterable platoon bits, reduced cutting tool vibration greatly, reduced the risk of blade of cutting tool collapse, and alleviated exorbitant feed. In make cutting point stronger respect, grind processing through point essence above all, because contain the easy collapse blade of big helix angle, be in especially blade is pointed, be close to in radial feed particularly 0.

Inside limits of 5 times diameter; It is to defend horn is designed next, when tall feed cutting, cutting tool flakes easily in the coating of point, collapse blade, defend horn allows tall feed to be worth; Pass the special processing to point namely additionally, the new cutting tool that handles via point does not have tiny collapse blade, also do not have grinding crackle, can acquire fast face quality. Avoiding to stick scrap respect, basically be right groove special processing, optimize through the technology accumulate bits and improve the surface to machine quality at the same time. Change coating (coefficient of friction) , reduce attrition (add refrigeration) , reduce those who accumulate bits to form a likelihood (groove) can reduce the possibility that sticks scrap. Use tall alloy steel, nickel / cobalt radical alloy and titanium alloy need optimize groove model material is qualitative, still can adopt smoother circular arc cut additionally, avoid to accumulate the formation of bits. To raise precision, want to ameliorate petiole common difference on one hand, it is especially in the superfinishing process of the mould, often need the knife handle of high accuracy, its precision is based on diameter, flatness and true circularity, high accuracy knife handle is homocentric spend an error most greatly 0.

005mm; Want to acquire the round part of high accuracy namely on the other hand, because jump over treatment of low ability of round horn public errand to go out more accurate shape finally product, in addition, high accuracy means what the choice suits to measure the method of round horn at the same time, fraisa uses 180 ° to be measured in the round detect the true precision of circular arc. Increasing efficiency respect, need has deepen / the special design of chamfer of gradual change helix, with improving the bending strength of cutting tool further, avoid cutting tool to rupture. Here, the gradual change chamfer of asymmetry, in the biggest flinch be apart from tigidity of positional cutting tool best, jump over in moment of force of susceptive of groovy back end small, cutting tool tigidity is better. Alterable helix chamfer reduced cutting tool vibration greatly, reduced the risk of blade of cutting tool collapse, alleviate exorbitant feed. Deepen / chamfer of gradual change helix can enhance craft stability, raise metallic purify rate. With detail the design reflects excelsior concept. CNC Milling
