How does the planarity compensation mechanism of the polishing disc affect the processing accuracy after the abrasive paper wears out?

1. Keeping the Flatness of the Workpiece
The flatness of the polishing disc is the benchmark for polishing and it directly decides the flatness of the workpiece. When the sandpaper wears out, the flatness of the polishing disc might go down because the wear can make the surface of the polishing disc uneven. At this time, the flatness compensation mechanism of the polishing disc is really important. Through this compensation mechanism, the flatness of the polishing disc can be adjusted to keep it at a high level. This makes sure that the workpiece can get even grinding during the polishing process and keeps its flatness.

2. Improving the Processing Accuracy
Processing accuracy is one of the important things to measure the polishing effect. When the sandpaper wears out and makes the flatness of the polishing disc go down, the processing accuracy of the workpiece will also be influenced. Because an uneven polishing disc can cause the surface of the workpiece to be uneven, and that lowers the processing accuracy. But the flatness compensation mechanism of the polishing disc can adjust the flatness of the polishing disc to reduce the influence of this unevenness on the processing accuracy and improve the processing accuracy of the workpiece.

3. Extending the Service Life of the Equipment
The flatness compensation mechanism of the polishing disc not only helps improve the processing accuracy but also extends the service life of the equipment. When the sandpaper wears out and the flatness of the polishing disc goes down, if the compensation isn't done in time, the wear of the polishing disc will speed up and then shorten the service life of the equipment. But through the compensation mechanism, the flatness of the polishing disc can be adjusted in time to reduce the wear and extend the service life of the equipment.

4. Specific Ways to Achieve the Compensation Mechanism
The flatness compensation mechanism of the polishing disc is usually achieved through a dressing mechanism or a reference plane electroplated diamond dressing wheel. The dressing mechanism can dress the polishing disc mechanically to make it get its flatness back. The reference plane electroplated diamond dressing wheel, on the other hand, uses the hardness and wear resistance of the diamond to dress the polishing disc finely and get a higher flatness. These compensation mechanisms can be chosen and used flexibly according to the wear situation of the polishing disc.
