Understand the application of the double disc surface grinding machine for the lower connecting rod

What problems will be encountered in the grinding process of the double disc surface grinding machine grinding wheel? How should we stop the disposal?

CBN grinding wheel burns the workpiece during the grinding process, and the hardness of the grinding wheel is high: the hardness of the appropriate grinding wheel should be changed. The direction of the coolant nozzle is wrong or the flow is not sufficient: adjust the direction of the coolant nozzle and increase the flow.

Grinding wheel dressing is not enough: Change the CBN grinding wheel dressing to focus on the new stop grinding wheel dressing. Workpiece grinding feed amount is too large: reduce the feed amount appropriately. Filter in the coolant is not clean: re-check and adjust the cooling system, grinding workpiece size continuity comparison is poor, the hardness of the selected grinding wheel is too large: change the appropriate hardness of the grinding wheel.

The appearance of CBN grinding wheel is jarred, the feed amount is too large: reduce the feed amount. Hard grinding wheel: reduce hardness, improve workpiece speed, speed up dressing. If the grinding wheel is not smooth: trim the grinding wheel again. Machine vibration: Check the vibration of the machine tool and the surrounding environment. The continuous comparison of the common workpiece size is poor, and the hardness of the selected grinding wheel is too low: change the grinding wheel with the appropriate hardness. Long life end grinding resin CBN grinding wheel.

The surface roughness of the workpiece after grinding is relatively poor, and the speed of the workpiece is too slow: speed up the speed of the workpiece. The coolant is not sufficiently filtered: check whether the filtration system of the coolant is normal, and the feed amount is too large: properly slow down the feed speed. The grinding wheel speed is too low: Adjust the rotation speed of the grinding wheel. Grinding wheel dressing is not in place: Adjust or change the CBN grinding wheel dressing pay attention to new dressing.
