Magnetic fluid grinding of ceramic balls - ScienceDirect

1/9/1995· Magnetic fluid grinding is a process capable of material removal some 10 to 25 times quicker than is lapping, for the finish manufacturing of ball bearings. It is fast because balls, driven through a viscous fluid, are caused to skid against a drive shaft at speeds which can reach 10 m/s. Material removal is by abrasive wear caused by grits

Grinding of Silicon Nitride (Si3N4) balls | Chalmers

2/6/2021· The material removal rate of 6.67 µm/minute and the roundness of 0.98 µm to 2.4 µm was achieved from the experimental grinding trails. The wear patterns on the grinding wheels are analysed and the subsequent wear rate for the trials are estimated. The optimized process is established with a cycle time of 400 minutes for producing 16 balls.

An optimum preload method for machine tool spindle ball bearings …

An experimental test rig for the optimum preload of ball bearings, which can automatically adjust the preload, was developed. The proposed method for determining the optimum preload was verified using the measured performance indiors, including the temperature, motor currents, and vibration of ball bearings.
