What problems will be encountered in the grinding process of the double-face grinder wheel? How should we deal with it?
1. CBN grinding wheel burns workpiece during grinding
(1). The hardness of CBN grinding wheel is too high: replace the grinding wheel with appropriate hardness.
(2). The direction of the coolant nozzle is incorrect or the flow is insufficient: adjust the direction of the coolant nozzle correctly and the flow is increased.
(3). Inadequate CBN grinding wheel dressing: replace CBN grinding wheel dresser and conduct grinding wheel dressing again.
(4). The feed rate of workpiece grinding is too large: properly reduce the feed rate.
(5). The coolant is not filtered clean: check and adjust the cooling system again.
2.The discontinuity of grinding workpiece size is relatively poor
The hardness of the selected grinding wheel is too large: replace the grinding wheel with appropriate hardness.
