First of all, try to use a small machining allowance, the purpose is to shorten the processing time and reduce the manufacturing cost of parts. Secondly, it is necessary to ensure that there is sufficient machining allowance, especially the machining allowance of the subsequent process, to obtain the required surface finish and precision. Later, when determining the grinding allowance, the size of the processed part should be considered. The larger the part, the greater the machining allowance. At the same time, it is also necessary to ensure that the grinding allowance is as small as possible without leaving the processing traces and processing defects of the previous process.
Then polish it according to slow and light reasons to eliminate serious oxidation, fine scratches and surface defects; the corresponding polishing agent will inevitably be used in this process, and attention must be paid to its selection. Light grinding is preferred. If the defect of the linear optical axis is serious, consider using a moderate or heavy abrasive.
In order to be more convenient for operation, product designers have also taken this into consideration, because in general, there is an oil injection hole on one side of each slider, as long as an appropriate amount of oil is injected into this oil injection hole.
