1. Improve processing efficiency: the processing speed is nearly 20 times that of honing
2. Improve surface hardness: The surface hardness increases by more than 50%. To
3. Processing accuracy: The processing accuracy can reach IT8 level, and the surface roughness can reach Ra0.05-0.4μm.
4. Working environment: low noise, no pollution, saving labor cost
5. Reasonable processing procedure: Scraping and rolling can be arranged as the last procedure to be processed after other procedures (such as oil hole drilling, welding, threading, etc.) are completed. The processing principle of the rolling tube: it is a kind of pressure light finishing. It uses the cold plastic characteristics of metal at room temperature, and uses a rolling tool to apply a certain pressure on the surface of the workpiece to make the metal on the metal surface plastic flow and fill the original In the groove, reduce the surface roughness of the workpiece. No matter how the rolled tube is processed, tiny bumps and uneven marks will appear on the surface of the part.
