Dotul Three Head Wide Belt Sanders MT-137 MT-143 MT-152

The MT series wide belt sanding machines are designed for the stile and rail door or cabinet industries. This machine is designed to prevent the standard rubber drums developing the wear marks or divots in the drum caused by the variations from the offset joints from stile and rail joint meeting areas.

Our first drum is steel to equalize the surface of the assembled stile and rail style door or cabinet doors. The second drum is rubber to assist in achieving a smooth finish and allow for additional grits to be used. The third sanding head is the final finish allowing the sanding platen to do the final finish with the finest grit paper. Digital controls ensure the accurate and consistent thickness for the sanding process.
