Then, the first driving member 230 drives the carrier plate 220 to rotate, so as to drive the brake disc to rotate, and further, the cutting process is performed on the brake disc by the tool on the lathe body 100. After one side surface of the brake disc is machined, the receiving ring 210 is radially turned 180 ° so that the tool can cut the other side surface of the brake disc. If further finishing is required, the containment ring 210 can be turned over again, so that the surface in front of the brake disc is machined, the time for repeatedly clamping the brake disc is saved, and the machining efficiency is improved.

It should be noted that, when repeatedly clamping the brake disc, the conventional clamp not only includes two steps of removing and clamping, but also needs to accurately align and clamp the brake disc at the same position, and this process is difficult and inefficient. In the embodiment, the device only needs to be turned over, and clamping is not needed again, so that the time for accurate alignment is saved, and the efficiency is improved.
