The processing technology and advantages of the cylinder tube

- Mar 25, 2021-

Advantages: Improve the surface roughness, which can basically reach Ra≤0.08μm . Correct the roundness, the ellipticity can be ≤0.01mm . Improve the surface hardness, eliminate the force deformation, and increase the hardness by HV≥4° . After processing, there is a residual stress layer , which improves the fatigue strength by 30% . Improve the quality of the fit, reduce wear and extend the service life of the parts, but the processing costs of the parts are reduced. The cylinder tube is a high-precision steel tube material processed by cold drawing or hot rolling. Because the inner and outer walls of precision steel pipes have no oxide layer, high pressure without leakage, high precision, high smoothness, cold bending without deformation, flaring, flattening without cracks, etc., they are mainly used to produce pneumatic or hydraulic components, such as cylinders or The cylinder can be a seamless tube. The chemical composition of the cylinder tube includes carbon C , silicon Si , manganese Mn , sulfur S , phosphorus P , and chromium Cr .
