Motimac WT RR1300,
Surface/Calibration Sanding Machine
The Motimac WT RR1300 Surface/Calibration Sanding Machine from NichoMachines is a two-roller wide-belt sanding machine, pairing a steel-shore first unit with a softer 70sh second unit to move from coarse calibration (P80 grit) to a finer finish (P120 grit) in one pass. Ball screws in each corner combined with a double-row chain hold precise table positioning, while a thickened, CAE-optimized steel frame keeps the machine stable under sustained load.
It’s built as a fixed-table roller sander — straightforward calibration-to-finish sanding without the added segment pad or cross-belt stages found elsewhere in the WT range.
