First, the reason for the non-circle of the part (1) the guide wheel does not repair the circle. (2) the grinding times are less or the last process ellipse is too large. (3) grinding wheel obtuse . (4) excessive wear or excessive knife . walking method : (1) repair guide wheel, to be repaired round stop (general repair to no intermittent sound stop). (2) properly increase grinding times. (3) rework grinding wheel. (4) reduce wear and heavy knife speed. Second, The part has an edge shape (polygon). (1) The part center is not high enough (2) The axial thrust of the part is too large. Unbalance the part against the retaining pin (3) The  grinding wheel  does not balance (4) The high center of the part center walking method : (1) the precision of the center of the part (2) reduces the angle of the grinding machine guide wheel to 0.5 ° or 0.25 °. When it is assumed that the gear is not able to be resolved, the balance of the fulcrum is to...

Firstly,the reason whythe center of the parts is big and small (1) The front and rear guide plates are uniformly inclined to the side of the grinding wheel (2) The grinding wheel is trimmed into a waist drum shape How to deal with the trouble  ofThe center of the parts is big and small (1) Adjust the front and rear guide plate (2) modify the  grinding wheel , each modification allowance should not be too large Secondly,the reson why there is a ring thread on the surface of the part (1) The front and rear guide plates protrude the surface of the guide wheel so that the parts are scratched at the edge of the guide wheel at the outlet or at the inlet. (2) The support ratio is too soft, and the cutting under grinding forms a protruding burr on the support surface, which is etched into a threaded line on the surface of the part. (3) The coolant is not clean and there are chips or grains inside. (4) At the outlet, due to the large amount of grinding, the gri...
