[0002] Polyurethane friction discs are friction discs made of polyurethane material, possessing many excellent properties. During the machining process of polyurethane friction discs, boring the center of the rough blank is required. However, due to the relatively low hardness of polyurethane, the machining speed of a single rough blank is relatively high. This leads to frequent disassembly and replacement of the rough blank during continuous machining of the friction disc, making the machining process time-consuming and inefficient. Therefore, we propose a boring lathe for polyurethane friction discs. Utility Model Content

[0009] Preferably, the curved groove is a trajectory combining a spiral and a straight line, and a limiting ball fixed to the inner wall of the circular sleeve is slidably disposed on the inner circumference of the curved groove.

[0010] Preferably, the end of the round sleeve is provided with an outer ring, the outer ring is fixed with a clamping head on the outer periphery, and a constraint shell fixed with the constraint tube is arranged between the outer periphery of the outer ring.

[0011] Compared with the prior art, the utility model has the beneficial effects that:
