Laquer sanding on edgesThe sanding of coated workpiece edges can take place in a stationary position on edgebanding machines or in the throughput on profile sanding machines. Here the sanding of coated edges offer the same conditions as for the sanding of coated surfaces. Requirements for the sanding of the lacquerContinuous sanding beld speedPressure and abrasion of the sandingbelt leads to warmth through which the varnish heats up and the sanding pours smear. The result is an uneven sanding image. As the different coatings have individual heating tolerance the sanding belt's speed has to be continuously regulatable. Continuously regulatable feedratesThe lower the sanding belt speed, the lower the feedrate has to be. For other sanding types high sanding belt speeds are required. Sanding padThe best results are reached when varnishing by using sanding pads. They have to be soft and elastically stored (e.g. pneumatically impindged). Deployment controlThe varnish layer is thin and especially the workpiece frontal edge is endangered (through sanding). The most effective protection are controlled pressure pads, as they are used with wide belt sanders.
