Rolling knife can finish the inner hole of the oil cylinder with one round trip. After processing, the accuracy of the inner hole of the oil cylinder can reach 8 level, and the surface roughness can reach Ra005-0.2μm. Compared with the traditional oil cylinder rolling process, the rolling cutter has many advantages, such as no cutting, no waste of residual material, can improve the product optical section, low manufacturing cost, fast efficiency, and can increase by 20-40 compared with traditional grinding technology. %, which is 75-95% higher than other honing heads. Below we will share the main features of the rolling cutter.
Main Feature
1. Improve the surface roughness, which can basically reach Ra≤0.08μm.
2. Correct the roundness, the ellipticity can be ≤0.01mm.
3. Improve the surface hardness, eliminate the stress deformation, and increase the hardness by HV≥40°
4. There is a residual stress layer after processing, which improves the fatigue strength by 30%.
5. Improve the quality of the fit, reduce wear and extend the service life of the parts, but the processing cost of the parts is reduced.
6. Improve processing efficiency: the processing speed is nearly twenty times that of honing
7. Working environment: low noise, no pollution, saving labor cost
8. 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.
