When seal cutting grinds stone, it will tilt when grinding. What are the polishing techniques?

1. When holding the stone, keep your fingers down as much as possible. The lower the center of gravity, the more stable the stone surface. Fingers can rub a little on sandpaper so as not to shake badly;

2. Grinding on a flat surface, such as glass, will not tilt only if the bottom surface is flat;

3. When grinding, you can grind according to the eight-character trajectory, and then change the direction several times until the grinding is in place.

Above, these. I hope I can help you.
