Following the launch of the Cubitron II Cloth Belt 984F, 3M have introduced an abrasive belt for medium-to-low pressure applications. Like its predecessor, the Cubitron II File Belt 947A incorporates precision shaped grain (PSG) technology.
The Cubitron II File Belt 947A by 3M has an expanded life-expectancy and much faster cut when compared with traditional abrasive grains. Field test results show 947A by 3M can deliver up to three times the life and up to two times the cut rate versus conventional ceramic belts, meaning fewer belt changes are required and increasing production rates respectively so saving time and money.
The new Cubitron II Abrasive Belts are made with X-weight poly-cotton backing so they are more flexible than the original higher pressure Cubitron II Cloth Belt 984F by 3M, making them ideal for use in operations using backstands, file belt and inline and stroke sanders.
In addition, a new grade of 120+ has been added for the first time in the Cubitron II Range so now there is an improved solution for finer finishing applications. As with 984F by 3M, 947A by 3M includes a grinding aid for use on stainless steel and heat sensitive metals as well as working well on carbon steels.
PSG technology means that each abrasive grain is triangular in structure and electrostatically orientated like a cutting tool, enabling it to slice through metal easily, continually fracturing to form sharp points and edges. This in turn creates a faster cut, longer life, and stays cooler because it removes the metal before it has a chance to heat up.
