steel tube boring process

The honing hydraulic cylinder is formed by the inner bore process of blank hot roller pipes. The main performance parameter is: cylinder material, tensile property, yield strength, elongation, inner or outer surface hardness, ID tolerance, inner hole, inner hole roughness and straightness, the material usually is 20 #, 45 #, 16 mn, ST52, etc. The whole steel tube will be heat treated, outer surface will be acid watering and phosphorized and then paint oil. As for how to choose the cutting tools, the company has several tools on the large boring lathe, they are deep hole boring tool, half-fine boring tool, fine boring tool and the roller head tool. The roller head tool will be services in the last procedure to make complete product surface which can reach planned ID tolerance as well, the inner hole surface is smooth, hard and wear-resistant.
