The phenomenon that occurs after a milling cutter is passivated

1, From the shape of chips, chips become thick, flake, chip color purple smoke due to chip temperature rise.

2, The roughness of the workpiece surface is very poor, and the surface of the workpiece appears bright spots with knife marks or ripples.

3, Milling process produces very serious vibration, and abnormal noise.

4, From the shape of the blade, the blade has a bright white spot.

5, When the use of carbide milling cutter milling steel parts, often fly out of a lot of fire fog.

6, With high speed steel milling cutter steel parts, such as oil lubrication cooling, will produce a lot of smoke.

When the milling cutter passivation, should be stopped in time to check the milling cutter wear, if the wear is slight, can be polished cutting edge oil stone, and then use; If the wear is heavy, it must be ground to prevent excessive wear of the milling cutter.
