When the grinding wheel is grinding the object under high speed rotation, the roughness of the module workpiece is poor and there are obvious vibration marks. What causes the abnormal occurrence?
Poor dynamic balance of spindle: readjust, and correct in the process of balance detection and correction.
If there is a large gap between the spindle or bearing, adjust it in time. Front bearing gap: 0.008mm, rear bearing gap: 0.012mm.
When the lubrication balance of CNC lathe table is not qualified, do a good grinding wheel balance, if necessary, do secondary static balance.
If the grinding wheel has uneven thickness, it should be corrected again to make the grinding wheel reach moderate thickness.
At the same time, clear all the source on the CNC lathe. For example: table rack, table impact, gear meshing gap is small, surrounded by a source, etc.. Gap as far as possible to control in ≤0.02mm range, carefully read the OPERATION of CNC lathe.
