Milling

In the selection of tool angle, we should consider the influence of many factors, such as workpiece material, cutting tool material, processing property (rough, finish machining), etc., we must choose according to the specific situation. The angle of the cutting tool, generally speaking, refers to the manufacturing and measuring the angle of annotation in the practical work, due to the different installation position of cutting tools and cutting motion direction changes the angle of the practical work and annotation from different angles, but usually is manufacturing tool materials school must have a high-temperature hardness and high wear resistance. The bending strength, impact toughness and chemical inertness necessary, good manufacturability (cutting, forging and heat treatment etc.), not easy to deformation.

Carbide indexable inserts have now been coated with titanium carbide, titanium nitride, alumina hard layer, or composite hard layer by chemical vapor deposition. The developed physical vapor deposition method can be used not only for carbide cutting tools, but also for high-speed steel cutting tools such as drills, hobs, taps and milling cutters. Hard coating as a barrier hindering chemical diffusion and heat conduction, the cutting tool wear in cutting speed, blade coating and coating life compared to increase about 1 to 3 times more polycrystalline cubic boron nitride is suitable for cutting high hardness of hardened steel and hard cast iron; polycrystalline diamond is not suitable for cutting iron metal and alloy, plastic, steel and glass; carbon tool steel and alloy tool steel file, and now it is used for die tip tools.
