Abrasive Belt 947A 3M Cubitron II

3M Cubitron ll abrasive belt 947A is intended for use from automated grinding with high pressure to low and medium pressure applications for coarse grinding. It can be used on equipment such as pedestal grinders, file belt sanders, inline sanders and stroke sanders. The belt features precision-shaped abrasive grains on a polyester-cotton X-weight cloth backing.
The precision-shaped abrasive grains are formed into triangular points that cut through metal rather than chiselling or ploughing like conventional abrasives. The points are self-sharpening because they generate new sharp edges as they fracture. This occurs with less heat generation, reducing heat-related cracking and discoloration. The abrasive provides a consistent finish throughout the product’s service life and helps avoid burn marks during final grinding.
The X-weight cloth backing is durable, and the mineral is bonded with a resin binder for reliable operation under high heat and pressure.
