Due to intense friction, leaving a high grinding zone temperature. This can cause stress and deformation of the workpiece, and even cause surface burns. It is necessary to inject a lot of grinding coolant to reduce the grinding temperature. Coolant also played Chip and lubrication.
Grinding large radial force. This causes the machine - Flexible concessions workpiece system, so that the actual depth of cut is less than nominal depth of cut - wheel. Therefore grinding will be complete, we should not feed light grinding to eliminate errors.
Abrasive blunt, the grinding force also increased, resulting in grains or broken off, again exposing the sharp edge, this feature is called "self-sharpening." Self-sharpening, the grinding can be normal within a certain time conduct, but work more than a certain time, give artificial trimmed, so the grinding force increases caused by vibration, noise and damage the workpiece surface quality.
Since the metal cutting wheels itself has high hardness and heat resistance, and therefore the grinding can be processed high hardness materials such as hardened steel, carbide.
