Description

Technical Field

[0002] Sponge sand block is a kind of grinding and polishing material with sponge as the base and abrasive sand implanted on the sponge. It is suitable for curved surface grinding and can absorb water, so it can maintain water grinding for a long time. After production, sponge sand block is usually cut into thin rectangles for easy hand-held operation so that it can be inserted into fine details for grinding.

Since the material of the cutting material itself is relatively soft, it is easily squeezed and bent by the clamping plates on both sides, making it difficult for the cutting machine to cut the sponge sand block straight, resulting in deviation of the cutting position and reduced cutting accuracy.
