Improper Matching of Feed Speed ​​and Roller Speed • Feed too fast: Insufficient friction time on the sheet surface, resulting in surface roughness and inadequate thickness correction. • Feed too slow: Prolonged contact between the sheet and the sanding belt can easily lead to surface burning, indentations, or over-cutting.

Industrial roller sanding machines have a wide range of applications, primarily in woodworking, metalworking, composite surface treatment, and building material production. Their uses extend beyond surface smoothing to include enhancing finish, controlling thickness, and pre-processing.

From an overall performance perspective, industrial wide belt sanding machines clearly outperform industrial roller sanding machines in the following areas: 1. Processing accuracy 2. Production efficiency 3. Scope of application 4. Level of automation
