The junction of the distributor and the entrance
Ball; 4. The junction of the distributor and the entrance of the cast iron disc does not match, Or the distributor retreats so that the steel ball stays at the entrance for a short time, and is injured by the 626 ball bearing
groove edge of the grinding wheel; 7. When the grinding wheel drops particles (blocks) on the surface of the ball, the local pressure increases sharply; 3. The cast iron disc has sand holes, pores and hard particles, which make the local pressure on the surface of the steel ball excessive; 6.Causes of spot burns: 1. The coolant is too dirty, and the grinding wheel is not cleaned up in time when repairing the grinding wheel.. The machine tool spindle bearing is damaged, causing the grinding wheel to swing too much; 5.
Goal channeling at the entrance of the cast iron plate; 8. The grinding wheel groove cracks or the defect of the broken block hits the steel. The speed of the grinding wheel is too fast, and the steel ball suddenly accelerates; 2. The pressure of the steel ball is too high; 9. The goal speed is too slow, and the number of steel balls between the grinding wheel and the plate is too small
