What is the function of precision piston rod?
This stainless steel piston rod is processed by rolling. Because there is residual stress on its surface, it will seal the cracks well and prevent it from being corroded.
Reasons for large piston rod runout:
1. Machining is better if the grinding sequence is not processed
2. The positioning datum is not the same datum or the shape and position error between the datums exceeds the tolerance.
3. The matching tolerance of each matching part is not selected properly
4. Support ring wear
The working mode of the precision piston rod is reciprocating motion. In order to increase the life of the piston rod and reduce the wear of the piston rod, 38CrMoAlA alloy structural steel is selected as the blank. Since the production type is batch production, in order to improve production efficiency, it is advisable to use the free forging method to manufacture the blanks. According to the technical requirements and assembly requirements of the piston rod, the left and right end faces of the piston rod and the center holes on both end faces should be selected as the precision reference.
