How to repair the spindle wear of an external cylindrical grinder?
1. Add one gasket to the left end of the skeleton oil seal installation position and the inner side of the left end cover of the main shaft, so that the area where the oil seal grinds the deep groove is blocked or staggered by the gasket. Due to the limited installation position of the left end cover of the main shaft, the thickness of the gasket cannot be too thick, but it must ensure that the position of the grinding deep groove can be avoided. Therefore, calculate, design and manufacture one gasket.
2. Dismantle the main spindle of the grinding wheel holder, weld the deep groove ground by the main spindle, and grind it after welding; Or disassemble and spray coat. For this malfunction, spray coating was chosen, and after spray coating, secondary processing is required. The requirements for accuracy and coaxiality tolerance during the grinding process are also quite strict. After the spindle maintenance is completed, it can be installed and restored for use.
