When sanding with sandpaper, it is easy to block powder and flakes, and lose the cutting power.
Jul 17,2026
When sanding, press lightly and at a constant speed to reduce friction and heat and avoid material melting and adhesion;
Use coarse-grit sandpaper for rough grinding, leaving a gap for powder discharge, and then change to finer grit for fine grinding;
Use dry sanding paper with an anti-clogging coating; sanding dust on sticky materials can be cleaned intermittently;
Once a large area is pasted and the cutting force drops significantly, replace the sandpaper directly with a new one.
