In the production of precision piston rods, attention should be paid to the three aspects of processing technology, process specifications and special fixtures in the process. Especially in the design of process specifications, some mechanical manufacturing theories and corresponding calculation formulas can be used to determine the manufacturing form of the blank, the selection of the processing base surface and the formulation of the process route, so as to obtain the machining allowance and determine the processing size and the size of the blank. , And then determine the cutting volume and basic working time.
