In recent years, machining center spindle is more and more speedy. For fitting the requirement of high speed machining on high hardness and strength materials and also prolonging mold life, the cutting tools advance its technology accordingly.
For example: customers’ demand about size, tolerance range, result up to mirror face, corner without joint point of tool exchange, cutting path of NC program, applications, and related issues.
Approx. types of cutters: single crystal diamond cutting tools, PCDs contenting CO diamond cutting tools, PCD containing Si diamond tools, PCBN cutting tools, metal porcelain cutters, tungsten carbide tools, HSS cutting tools, general steel cutters. Select proper cutting tools according to work piece.
Generally based around the shape, surface tensile, surface rotation, ball rounded shape, conic, cylindrical curve shape, and other relevant conditions of work piece to choose the shape of end mills. The neck types of end mills are divided into standard, long-neck, and cone-neck. Select cutters according to the machining depth of the work piece, shape, appearance, processing objects, crude/middle/fine three milling paths, and other related conditions. Long-neck and cone-neck types can process deep machining, it should take into account about the interference angle during selection in both .., Compared with the long-neck type, the high rigidity of the cone neck type milling cutter may promote cutting conditions and achieve better machining accuracy, you should choose cone-neck type end mills.
The arc accuracy of ball end mills is typically ± 5μm; there are also ± 2 ~ 3μm high-precision end mills available for high-precision processing.
BW TiALN coating is suitable for machining carbon steel and hardness below HRC40 of work piece; Nano titanium aluminum nitride film-NanoTiAlN coating is for alloy steel S, tool steel, and HRC50 work piece; BW TiALN + PLCcoating. Is good for higher hardness, hard alloy material of work piece.
For example: if cutting metal composite material, you should choose BW metal ceramic cutter or PCBN diamond tool to solve cutting problems because the material is with high nickel content.
