Aviation metal is efficient cutting cutting tool
Efficient cutting cutting tool basically has metal of Zheng getting aviation alloy of milling cutter of aluminium alloy high speed, titanium is efficient alloy of milling cutter, high temperature is efficient coating milling cutter, basically be aimed at the efficient cutting with aluminium alloy of high strenth of aviation structural member and difficult treatment qualitative material, be like costal region of aviation aircraft ala, ala the structural member such as Liang Hemeng skin. Milling cutter of Zheng Zuan high speed and photograph of traditional milling cutter are compared, can achieve higher metallic purify rate and precision of thin wall dimension, cutting force is smaller, treatment quality is more superior.
Milling cutter of aluminium alloy high speed, basically apply at 7050 with structural member of aluminium alloy of 7075 high strenth model efficient high accuracy machines antrum Baobi high speed. Essence of face of the knife before cutting tool structure designs the circular arc point in is ground, can increase circular arc precision and point strength; Full point design has damping first flank; Helix chamfer polish is handled; The design that carry tine repairs Guang Ren, be helpful for rising to already machined exterior quality. Titanium alloy is efficient milling cutter, have differ edge is wide, columnar point, special slot, the structural characteristic that exceeds big helix angle. Machining muscle of titanium alloy independence the structure opens slot in, former 4 blade milling cutter machines feed 200Vf, metallic purify leads 40Q, use now new-style efficient milling cutter machines alloy of 5 blade titanium, can obtain metallic purify to lead 191cm3/min, and treatment is smooth, platoon bits is smooth, ra1.6 of exterior surface roughness.
High temperature alloy is efficient coating milling cutter, circular arc point, knife face is repaired before grind, increase circular arc precision and point strength; Differ edge is wide, columnar point is designed. Blame all the cutting blade of cloth shakes with avoiding, big helix angle benefit at discharging bits, can raise the treatment precision of workpiece. Basically use at machining high-pressured turbine to direct blade supports package, cutting technology reachs international level.
Aviation answer material is efficient cutting cutting tool
The aviation that Zheng Zuan develops efficient cutting cutting tool has answer capable person enough and sharp cutting blade, enhance material to carbon fiber (CFRP) , fibre glass enhances material (GFRP) and aluminium radical carborundum (SiCp/Al) the effect of composite material treatment that waits for difficult treatment is admirable, the material that in solving composite material effectively to machine a process, appears is statified, tear off, the blemish such as burr. In obtain fine effect of accurate, bright and clean cutting while, treatment efficiency is taller, wearability is better, cutting tool life is longer. Be like: Cutting tool of cutting tool of series of treatment of aperture of cutting tool of PCD milling series, PCD, beehive cutting series. PCD milling cutting tool machines CFRP, do not suffer machine tool of be confined to to slant to place angle and make workpiece appears burr, basically have milling cutter of diamond coating alloy and PCD3 blade milling cutter, use at getting mill chamfer, hole milling.
PCD aperture machines cutting tool, machine with the nicety at aperture of composite material difficult treatment, main cutting tool has PCD Huo Huo of broach of nest getting, PCD, PCD getting is compound knife. This kind of cutting tool solved Kong Zhong of bore, Huo well workpiece occurrence burr, statified, tear off wait for invalidation condition, hole wall and control of surface roughness of Huo nest face are in Ra3.2 less than; Service life of cutting tool of aperture of bore, Huo reachs life of congener entrance cutting tool.
Cutting tool of beehive cutting series, use at processing beehive structure data. Composite material of beehive interlining construction exceeds the characteristic such as light qualitative, high strenth, tall wear because of its, already applied at the plane in great quantities advocate, second bear force structure, if cover of empennage of wing, airframe, radar reachs floor, interior trim,wait for place. Zheng gets cutting tool of series of this kind of cutting to basically have NOMEX beehive broken milling cutter, aluminous a honeycomb-like thing the broken milling cutter, NOMEX beehive supersonic milling cutter, interlining beehive that can process a variety of types, surface of answer material cutting relatively level off, without burr, thin wall brim is flowing and complete, cutting tool technology achieves international advanced level.
As the development of technology, and of level of advanced manufacturing industry rise, aviation industry data also gets upgrading ceaselessly developing, development of structural member of aviation aircraft whole tends large change, the spare parts tends complication, use material tends diversity, and treatment precision requirement also develops to taller direction. Zheng Zuan complies with the demand that the market expands from beginning to end, rise to throw many technology and capital force continuously for what aviation exceeds level of strong cutting tool, the cutting tool that is industry of our country aviation is homebred the devotion that turns development to make his.
