Compared with traditional honing processing, fine boring and rolling pipe has the following advantages:
⑴ Improve processing efficiency: processing speed is nearly 20 times that of honing
⑵Improve surface hardness: The surface hardness is increased by more than 50%.
⑶ Processing accuracy: The processing accuracy can reach IT8 level, and the surface roughness can reach Ra0.05-0.4μm
⑷ Working environment: low noise, no pollution, saving labor costs
⑸ Reasonable processing procedures: Scraping and rolling can be used as the last procedure to be processed after other procedures (such as oil hole drilling, welding, threading, etc.) are completed.
