Stainless steel tube, diameter 10 how to polish inner hole

Quilting can be done using a quilting mill to polish holes in the tube, a vertical drill (if the hole is not too deep) or a rocker drill. Quilting is to use the quilting head for quilting. The structure of the quilting head is cylindrical, with several grooves on the circumference for installing oilstone strips. Pressure springs are installed on the bottom of the grooves. During quilting, the pressure spring pushes the oil stone to the inner wall of the round pipe, and the quilting mill drives the knife bar of the quilting head to rotate up and down to polish the inner wall of the pipe. In general, quilters have a much longer trip than vertical drills or rocker drills and can be used to work on longer pipes. The vertical drill or rocker drill can only work short pipes. The precision of quilting can reach 0.01mm. Chemical polishing can only polish the inner wall of the pipe is very smooth, the inner wall roughness of the pipe pipe is not suitable.
