St52 hydraulic cylinder tubes have the following advantages over conventional honing:
(1) Improve processing efficiency: processing speed is nearly 20 times that of honing
(2) Increase the surface hardness: the surface hardness increases by more than 50%.
(3) Machining accuracy: processing accuracy can reach IT8 level, surface roughness can reach Ra0.05-0.4μm
(4) Working environment: low noise, no pollution, saving labor costs
(5) Reasonable processing steps: scraping and rolling can be processed as the last process after other processes (such as oil hole, welding, threading, etc.) are completed.
