Equipment Highlights

Equipment Highlights

(1) Four-station upper plate vacuum adsorption polishing machine.

(2) The workpiece is fixed on the jig by vacuum adsorption. The wool blanket is fixed on the surface of the lower plate, and the friction between the wool blanket wool, polishing liquid and glass is used to polish the curved surface of the glass.

(3) The upper and lower discs of the machine can be controlled by the numerical control program, and the stepless speed change can be realized according to the process requirements to meet the requirements of different polishing processes.

(4) The electric proportional valve is used to accurately control the polishing pressure to ensure the polishing accuracy.

(5) The upper polishing disc is driven by a speed regulating motor, and a cylinder controls its lifting and pressurizing.

(6) This machine adopts the combination of human-machine interface HMI and programmable control PLC, which is convenient and quick to operate and improves work efficiency.

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

(8) The control components are all 24V power supply, and the PLC power supply is powered by isolation transformer, which reduces the external power grid clutter and interferes with the safety of the machine tool.
