How can the inner walls of stainless steel tubes be polished?
After polishing, because the surface oxide layer received damage, it is best to use acid solution surface passivation treatment, otherwise it is easy to rust.
Electropolishing is thrown to the workpiece as anode, insoluble metal poles at the same time as the cathode, immersed into electrolytic cell, with the direct current produced anodic dissolution selectively, so as to achieve the surface brightness increasing effect. Specific can be used to search "what is electrolytic polishing" can understand!
1) (used in polishing the inner surface polishing machine): rod is thrown into the tube to drive the impeller 1000 or homemade abrasive wheel rotating speed, and with the rotation of the polishing pipe itself, while rotating slowly forward throwing rod. Generally speaking, first use the 60#-80# wheel of Chiba or abrasive belt wheel for rough throwing, and then gradually fine throwing with high precision according to the requirement of smoothness. Large size pipe 6, more than the general use of thousands of impeller, small size of the pipe can be made with homemade abrasive belt wheel, you can reduce costs.
