Equipment Highlights

Equipment Highlights

(1) This machine belongs to the grinding machine of the motion principle of 4 planetary gear trains.

(2) The weight of the pallet of this machine falls into the bottom plate through the hollow shaft, the fixed sleeve, the pair of tapered bearings and the three supporting feet, which can ensure the extremely high pallet end jump. In addition, this machine is also equipped with a correction wheel to repair the flatness error of the upper and lower grinding discs.

(3) The sprocket is driven by the reducer, and the driven sprocket drives the three screw rods, so that the ring gear moves up and down smoothly, with a high degree of automation.

(4) The machine is equipped with a pressure detection mechanism for pressurized grinding of the workpiece, which automatically detects the current pressure of the workpiece. It is also equipped with a matching electric proportional valve for automatic pressure adjustment.

(5) This machine is equipped with a safety self-locking cylinder. When the upper grinding disc rises to the upper limit point, the insert plate extends to prevent the upper grinding disc from falling and ensure the safety of the operator and equipment.

(6) PLC control, flexible and reliable control mode.

(7) The touch screen is used as the man-machine interface to display real-time information of alarm and machine tool status; the interface is friendly and the amount of information is large.
