Abstract: An intelligent display assembly includes a display and a microcontroller. The display is mounted to a CNC machine and provided with a light emitting module and a display module opposite to the light emitting module. The microcontroller is electrically connected with the CNC machine and the display, such that the microcontroller receives an operating status signal outputted by the CNC machine, and according to the operating status signal, the microcontroller controls the light emitting module to emit light and controls the display module to display processing information, such as processing time, processing quantity, waiting time, and failure time. This allows operators to grasp the processing information in real time and improve management efficiency.

Abstract: 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.
