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.
3.Vibration lines appear on the surface of CBN grinding wheel
(1). The feed rate is too large: reduce the feed rate.
(2). The grinding wheel is hard: reduce the hardness, increase the rotation speed of the workpiece, and speed up the dressing.
(3). The grinding wheel is not leveled: the grinding wheel is trimmed again and the vibration of the machine tool is checked.
4. The continuity of common workpiece size is poor
The hardness of the selected grinding wheel is too low: replace the grinding wheel with appropriate hardness. Long-life resin CBN grinding wheel for end grinding
5. The surface roughness of the workpiece after grinding is relatively poor
(1). The speed of the workpiece is too slow: accelerate the speed of the workpiece.
(2). The coolant is not filtered sufficiently: check whether the filter system for adjusting the coolant is normal.
(3). Excessive feed rate: appropriately slow down the feed rate.
(4). The rotation speed of grinding wheel is too low: adjust the rotation speed of grinding wheel.
(5). Inadequate dressing of grinding wheel: adjust or replace CBN grinding wheel dresser for dressing.
(6). The selected grinding wheel size is not matched: replace the matched grinding wheel size.
