[0019] like Figure 3 As shown, the mounting end of the grinding mounting plate 101 is designed to be able to replace various processing parts. The processing parts can be selectively installed on the grinding mounting plate 101 according to the actual groove processing needs, so that the groove machine can process various grooves after the processing parts are fixed on the device; the surface of the roller 7 is covered with a buffer pad, which can be a rubber elastic pad. The buffer pad can buffer the pressure of the roller 7 when clamping the workpiece to be processed to prevent the roller 7 from damaging the surface of the workpiece.
