How to polish the bore of precision stainless steel tube? Foshan Gangzheng stainless steel to tell you:
1, electrochemical polishing
bore polishing is usually used in electrochemical polishing methods, because of its high production efficiency, low cost, increase tube surface corrosion resistance. But for other small diameter precision stainless steel tube mostly mechanical methods, bore polishing is difficult, inspection is difficult, time-consuming. Inner hole with electric spark discharge machining, high processing precision, good finish, but time-consuming. Through effective means, can solve a variety of inner hole polishing deburring? , mirror polishing problems.2, quilting mill polishing
Of course, you can also use quilting mill for precision stainless steel round tube bore polishing, you can also use the vertical drill (if the hole is not too deep) or rocker arm drill to quilting capacity grinding. The quilting is carried out by using a quilting head, which is cylindrical in structure, with several grooves around the circumference for installing oil stone strips, and a compression spring is installed on the bottom surface of the grooves. When quilting, the pressure spring pushes the oil stone to the inner wall of the round tube, and there is a quilting grinder driving the cutter bar of the quilting head to rotate up and down to polish the inner wall of the tube. Generally speaking, the stroke of the quilting mill is much larger than the stroke of the vertical drill or rocker arm drill, and the use of the quilting mill can process longer precision stainless steel tubes. Vertical drills or rocker arm drills can only process shorter tubes. The precision of quilting can reach 0.01mm a little, chemical polishing can only polish the inner wall of those tubes that are originally very smooth, the inner wall of the tube roughness is not good for the tube is not applicable.
