First use the speed-adjustable Angle Grinder and the No.1 Grinding Pad to perform rough grinding. Note that the Grinding Pad must be leveling with the glass, and the speed can be adjusted at the speed-level Angle Grinder to about 2500-3000 rpm.
When using No. 1 Grinding Pad, you can perform grinding directly without adding water, please note that the operation must be moderate, smooth, and orderly.
After rough grinding of No.1 Grinding Pad is completed, it shall be replaced with a No.2 Grinding Pad for fine grinding. During the operation, the grinding range should be greater than the No.1 grinding area to prevent any occurrence of deformation.
In order to ensure the highest effectiveness of grinding, the glass powder on the Grinding Pad should be removed in time during the operation.
After completion of fine grinding, replace it with a Polishing Pad and conduct the polishing work.
During the polishing process, add water continuously and observe the polishing effect at any time.
The polishing finished, and the repairing work completed.
