Milling processing technique basically has tendency of 3 kinds of development: (1) high speed milling; (2) horniness and milling of difficult treatment material; (3) the high speed milling of horniness and difficult treatment material. To suit 3 kinds develop a tendency, each country is famous newest research and development gives cutting tool production company the following kinds of advanced cutting tool: Ceratizit company (be located in the Colombian city that Luo Laina city blocks south the United States) the HSC-11 milling system of new development, have the following 3 big characteristics: ① can issue treatment in the rotate speed of tall main shaft of 56000rpm, excision rate amounts to 3500cm3/min; Design of ② razor blade is excellent, and the superfinishing of classics micron class; ③ can be used at processing all sorts of data, and can machine below all sorts of conditions. Kennametal company (the Latrobe that is located in Ni Yazhou of guest evening standard) new the hard alloy milling cutter that roll out, when processing black metal data, can improve cutting tool service life 30% . The dry formula that milling cutter of KC935M hard alloy basically uses Yu Gang and nodular cast iron or wet cutting; What milling cutter of KC915M hard alloy basically uses at casting pig and nodular cast iron is light to in carry cutting. Surface of two kinds of cutting tool was used in lukewarm CVD (MTCVD) multilayer and compound coating. Additional, still undertook an aftertreatment to coating, enhanced the adherent power of coating admirably, reduced coefficient of friction, improved coating quality. Walter Waukesha company (be located in Weisikangxin the Waukesha) development of the city gives the series of milling cutter of Xtra · Tec that is used at end panel and step milling, what the among them F 4033 knife that carry mill chooses is the double-faced square bit that has blade of 8 effective cutting, because bit structure semmetry is reached,get power even, special agree with to be exchanged toward dislocation of two or so direction (cutting blade) , use very convenient. Milling cutter of type of F 4042 current chance to extricateoneself from an awkward position, in order to have big before horn is main characteristic. Big before horny milling cutter can make cutting force is reduced, decrease to power is used up and reduce exterior surface roughness, it is thick, the best choice of spare parts of finish machining steeliness and cast. Company of a few cutting tool is the closest already of will new development advanced insert into type milling law (Plunge-cut Milling) in using the design at new-style milling cutter, with improving the treatment function of milling cutter further. The CoroMill 210 of Sandvik Coromant company milling cutter is compound Duan Xi and insert mill two kinds of functions, make feed speed promotion ages for 4mm/ . When Duan Xi, can make excision measures promotion to 1400cm3/min, include to be opposite deeper model late chance to extricateoneself from an awkward position of antrum and exterior uses treatment of the law that insert mill. The specification that at present this milling cutter provides is diametical 25~82mm. Iscar metal company (be located in Texas Arlington) the PLX Plungers that new development goes inserts milling cutter, it is OK to have conveniently feed and from deeper model the characteristic that the knife retreats in antrum, treatment efficiency is consequently tall. Machine good spare parts appearance to avoid bit damaged and cut, insert milling cutter to design the yield that has 45 ° technically to pour wine cup. Cancelled to be sometimes make cutting tool fast and retractile (let a knife) and the program of cutting tool shift that designs technically. Use a cutting tool to be able to undertake inserting mill of type thick mill, essence of life or half essence mill to come true, return elaborate design the blade of cutting tool cutting of two special structures. At the same time development goes those who insert milling cutter to still have Stellram company (the LaVergne) that is located in Tennessee. The 7791 VS of this company new development inserts milling cutter, the productivity of its outline milling raises 10 times above than traditional milling, it is the ideal cutting tool of metal of outline milling black and rough machining of nonferrous metal material and semifinishing machining. The system uses the bit of 4 cutting blade, thereby but what the basis machines a diameter is different, edge radial cutting is the biggest amount to 8 or 11mm. M.


Ford company (the thick, finish machining that is located in the TuffCut XR hard alloy of the Davenport) new development that loves Russian China city to establish milling cutter to be able to be used at all material. Should establish milling cutter to already had 240 norms at present, include square petiole, the radius of circular arc of point of a knife of a variety of dimension, short model, standard type, long model with train in excess specified length model groove is long wait. The geometrical appearance of the chamfer that discharge bits is Heli-pitch, the resonance that can reduce the generation in treatment swings, allow to undertake big feed and tall cutting speed are machined. At present the diametical norms of this product has ″ of 1/8 ″ ~1 and 3~25mm, coating is AlTiN. Emuge company (be located in Washington city Northborough) to be efficient treatment the small amount that contain silicon (5% ) aluminium alloy development goes integral hard alloy special establish milling cutter. Its are main the characteristic is, the form of cutting tool geometry that designs technically can be reduced admirably cut the interface between bits and cutting tool to accumulate, make cut bits to eliminate easily and reduce cutting tool to produce the opportunity of damaged because of wearing away badly at the same time; Coating of TiB2 of Fu of besmear of cutting tool surface. The company still is development of aluminium alloy of efficient treatment tall silicon to give integral form hard alloy razor blade and milling cutter. CNC Milling CNC Machining
