Can the alloy milling cutter 20CrMnTi the workpiece after carburizing and quenching?
Over the depth of carburized layer, due to lower cutting speed, fully cooling, but the effect is not very good
Alloy milling cutters can not be milled 20CrMnTi carburized and hardened workpieces. Because the HRC hardness of the alloy milling cutter is only 60 degrees, and the HRC hardness of the surface layer after carburizing and quenching of 20CrMnTi is also 60 degrees, and the milling cutter as a cutting tool is absolutely impossible to cut the workpiece with the hardness comparable to it. It can only cut the workpiece with less than half the hardness. Because the cutting is carried out in the case of cutting force, cutting tool must have edges in hardness almost close to the case, the blade cannot cut into the workpiece, the friction between the blade and blade workpiece temperature, annealing, the hardness decreased, without any cutting action. Tungsten steel knife hard alloy cutting, but also wear large, short time use only.
If it's urgent, only a little hard alloy can be used. If used for a long time, it is recommended to use high hardness carbide milling cutters! Because each manufacturer will be based on the material to be processed by different design of different milling cutter! So it's better to find a special milling cutter! The processing life and the processing effect will meet the requirements
