Causes of retention of mechanical metal chip cutters
Because it is affected by the work hardening, the hardness of the product is about 1~2 times higher than that of the base metal, so it can be partly replaced by cutting edge.
Product cut tumor is unstable in the cutting process, it is time now, later, to a certain height, broken by the workpiece and cutting away and disappear, and then destroy the estate was born again and again. The surface of the workpiece is uneven and the surface roughness decreases. It also causes vibration during cutting and speeds up tool wear.
In metal cutting, the reason why the cutting edge causes the accretion is that the cutting metal is formed by bonding with the tool before the high pressure and big friction force in the cutting zone.
