This series of sanders are not restricted by own thickness difference of board materials,and the thickness and precision can be obtained through double-side sanding. They have thecharacteristics of high precision (thickness tolerance within ±0.08mm after double-sidesanding),excellent quality and high efficiency (single side or double-side thicknessingsanding can be finished at a time). They are mainly applicable to thicknessing and finesanding of chipboard, medium density fiberboard, core board, high pressure veneer,laminated plywood, cement chipboard, medium density calcium silicate board and solid woodlaminated board, etc.
