The general arrangement of the processing hydraulic fittings manufacturers sequence is based on the structure of the part and the condition of the blank, as well as the need for positioning and clamping. The key is that the rigidity of the workpiece is not destroyed. The sequence should generally follow the following principles:
1. The processing of the previous process cannot affect the positioning and clamping of the next process, and the general machine tool processing processes should also be considered comprehensively.
2. Carry out the inner cavity adding procedure first, and then the contour processing procedure.
3. It is best to connect the processes of machining with the same positioning, clamping method or the same tool to reduce the number of repeated positioning, the number of tool changes and the number of moving the platen.
4. For the multiple procedures carried out in the same installation, the procedure should first be arranged with less rigid damage to the workpiece.
