The utility model provides a wheel hub's rim processing equipment belongs to mechanical technical field. It has solved the problem of putting forward high pressure heater worker precision when how to improve the outer surface machining efficiency of rim. This rim processing equipment includes the lathe bed, three -jaw chuck and rotation motor, the last centre gripping of three -jaw chuck is fixed with clamping device, be fixed with stand no. 1 and stand no. 2 on the lathe bed, sliding connection is gone up to stand no. 1 has mount no. 1, sliding connection is gone up to mount no. 1 has the lathe tool, sliding connection is gone up to stand no. 2 has the slide, be equipped with mount no. 2 on the slide, sliding connection is gone up to mount no. 2 has molding cutting tool/molding cutter, have on molding cutting tool/molding cutter's the surface with the outer the same shaping portion of surface profile of rim, shaping portion can be tangent with the rim surface. This equipment is through setting up lathe tool and specific molding cutting tool/molding cutter, the mode of adopt the car, grinding combined machining to wheel hub's rim surface go on slightly, finish machining, improved the machining precision of rim surface in the surface machining efficiency outside the improvement rim.
