Pneumatic belt sander operating procedures

When performing sanding operations, the parts must be held firmly and approach the belt slowly following the shape of the part; pay attention to gradually increase the strength of the grip when the part approaches the belt.

During the sanding process, it must keep swinging back and forth to prevent the uneven force from deforming the sand of the parts.

During the operation, the direction of sanding must follow the direction of the wood grain, otherwise there will be horizontal sand marks on the surface of the parts; but for some criss-cross parts, first horizontal and then vertical, will have a better surface quality effect.

It is necessary to check while operating, and there must be no sand deformation, no sand in place, fuzzing, etc. If sand marks are serious, they must be dealt with in time.

For the parts that are filled with soil or wood ash, they should not be sanded until the soil and wood ash are completely dried to prevent the soil and glue from sticking to the sanding belt, causing poor sanding.

The processed parts should be placed on the pre-prepared backing plate or material rack and stacked neatly.

After the operation is completed, turn off the power, clean the operation site, and maintain the equipment in accordance with relevant regulations.
