TH100555B - Manufacturing methods and manufacturing machines of glass substrates for magnetic record plates And manufacturing methods of magnetic record plates - Google Patents

Abstract

The bottom shaft 19 of the main body, the gripper 17 of the workpiece holder is fixed onto the platform 5, the shaft 12 is arranged perpendicular to the bottom wall 19 substrate. A number of glass grades 2 have been stacked onto the bottom wall 19 and are aligned to allow the 12 shaft to pass through the inner hole of the glass substrate. While the glass substrate through alignment 2 is pressed from Above, with the press part 22 of the clamping piece 18 of the shaft holder 12, has been taken out of the corresponding inner hole of the glass substrate 2 and a smooth brush has been inserted. Into the inner hole For smoothing
