What should be paid attention to when processing non-standard fixture parts?

Points for attention in non-standard fixture accessories grinding requirements:

1. The abrasive grain size should be changed from coarse to fine and sequentially. When changing the abrasive, the grinding trace of the previous process should be completely removed, and the grinding should be carried out until the grinding trace can only be seen. It is very important to prevent the occurrence of "relief" phenomenon.
2, the same lap can only use the same size of abrasive, each time before changing the particle size, the workpiece must be completely finished, so as not to bring the coarser abrasive or the remaining dirt to the next process, forming a scratch on the grinding surface .
3. Every time you go to the next particle size conversion, it should be ground at a 30-45° angle with the last grinding target. If there is a deep wound, it is not only possible to grind the surface of the sheet, otherwise the sheet position will be pitted, and the whole plate should be trimmed to remove the pit. For both simple and non-smooth stations, attention needs to be paid to the average grinding.
