- When chrome rod grinding the outer cylindrical surface, the workpiece is prone to tool deflection and elastic deformation, affecting the accuracy of the piston rod. Therefore, the center hole should be honed and kept clean during machining. The tightness between the center hole and the top should be appropriate, and good lubrication should be ensured. The following grinding wheel selection is generally used: white corundum (WA) abrasive, 60# grit, medium to soft hardness, or medium-hardness with ceramic bonding. Additionally, a narrower wheel width should be chosen to reduce radial grinding force. During machining, pay attention to the selection of grinding parameters, especially the depth of cut.

- When grinding the outer diameter and 1:20 taper, the two processes must be performed separately. When grinding the 1:20 taper, a test piece must be ground first, and only after the test piece passes inspection can the workpiece be ground formally.
- To ensure the stability of the piston rod machining accuracy, manual straightening is not allowed throughout the entire machining process.
