At present, the surface quality of strip steel (especially automobile plate) is getting higher and higher, and the steel plant generally uses CCD to test the surface quality of strip, but it needs to make artificial grinding on the surface of strip before CCD detection, so as to expose the surface defect fully. For this reason, the company specially designed an automatic grinding device, which can be used by the users to grinding both sides of the strip, using two sides elastic to grinding and grinding, using X, Y two coordinate CNC system to drag the grinding head, simulate the hand grinding track and route, and realize the automatic grinding of the strip surface. The device is successfully applied to the 208 unit of Baosteel.
