Abstract: Semi-automatic cylindrical grinder MB1632 spindle shaft diameter due to long-term use, resulting in its wear and leakage, this problem has seriously affected the company's normal production order. This paper mainly introduces a method to improve the wear oil leakage of the spindle shaft diameter of the semi-automatic cylindrical grinder MB1632. The root cause of the wear oil leakage of the spindle shaft diameter of the grinder is analyzed. The oil seal end cover is optimized and improved synchronously to realize the contact between the oil seal and the spacer sleeve. The end cover, the oil seal and the spacer sleeve can be removed quickly. It not only improves the maintenance efficiency of the spindle shaft diameter wear oil leakage problem, reduces the maintenance cost, but also improves the operation probability of the machine tool.
