Causes of surface burn of workpiece after machining by CNC cylindrical grinder
1. Improper feed control. The countermeasures for this reason are: reduce the feed amount, use a larger feed amount at the beginning of the production of the CNC cylindrical grinder, and use a relatively small amount in the last few cuts to reduce the grinding depth.

2. The selection of grinding wheel is wrong. Grinding wheels with small particle size, soft hardness and loose organization should be selected. Use large-hole grinding wheels to keep the grinding wheel grinding under sharp conditions, and select suitable cutting fluids with good lubricity to reduce the friction between the abrasive particles and the workpiece.

3. The friction of the contact surface between the grinding wheel and the workpiece causes problems. At this time, the contact surface between the grinding wheel and the workpiece can be reduced and the heat generation can be controlled.
