Advantages of rolled pipe compared with traditional honing process

Compared with traditional honing processing, precision boring and rolling tubes have the following advantages:
       ⑴ Improve processing efficiency: the processing speed is nearly twenty times that of honing
       ⑵ Improve surface hardness: surface hardness increases by more than 50%.
       ⑶ Processing accuracy: The processing accuracy can reach IT8 level, and the surface roughness can reach Ra0.05-0.4μm
       ⑷Working environment: low noise, no pollution, saving labor costs
       ⑸ Reasonable processing procedures: Scraping and rolling can be arranged as the last process after other processes (such as drilling oil port holes, welding, threading, etc.) are completed.
