Equipment Highlights

Equipment Highlights

1. The rotation of the lower polishing disc is driven by a variable frequency motor. The motor is installed on the base plate of the equipment bed, decelerated by the reduction box, and transmitted from the reduction box spindle to the lower disc spindle through the coupling. The mechanical rigidity of this part is high, the coupling can absorb part of the vibration, and the vibration will not occur during polishing, which is beneficial to improve the polishing quality of the product.

2. Using PLC and touch screen control, the process parameters under different pressure conditions can be preset in the touch screen.

3. The drive motor adopts advanced and reliable frequency converter to realize stepless frequency conversion speed regulation, and the upper and lower disks can realize controllable speed regulation according to the processing technology requirements.

4. The lower plate is arranged with a real air path. The workpiece can be fixed by adding vacuum to the adsorption pad. After the workpiece is processed, the workpiece can be pressed through the positive pressure to break the vacuum and blow back the workpiece to facilitate the disassembly of the workpiece.

5. The lifting and tilting of the upper plate is controlled by cylinder, which is controlled by solenoid valve and electronically controlled proportional valve. The cylinder action is stable and reliable, and the polishing pressure is accurately controlled.

6. The imported brand electric control proportional valve is adopted to accurately control the down pressure of the grinding disc through the fine adjustment setting of the air pressure size. With PLC automatic control, the initial pressure and grinding pressure of multiple stages can be accurately set.

7, the processing process adopts PLC automatic control: can control time, pressure, speed.

8, automatic control of the grinding liquid circulation system, so that the grinding liquid repeatedly reflux mixing barrel, reduce the cost of consumables.

9, equipment structure and system are self-developed, can achieve the effect of customization according to customer needs.

10. The man-machine operating system is convenient for personnel to control and set, and the setting function can be added according to customer needs.
