CYLINDER-TYPE POLISHING MACHINE

摘要

A polishing machine is disclosed to include a machine body and a carrier movably coupled to the machine body. A polishing device is provided with a movable base movably coupled to the machine body and a plurality of polishing cylinders rotatably connected to the movable base and located above the carrier. A rotary drive device is provided with a plurality of transmission gears each coupled to one of the polishing cylinders, and two rotary drive motors symmetrically mounted to the movable base and each having a gear shaft for driving the transmission gears to rotate through at least one transmission belt. Thus, the polishing cylinders are moved along with the movable base and rotated by the actuation of the rotary drive motors for smoothing the workpieces placed on the carrier.
