Grinding wheels cut faster, last longer and need less pressure

3M is introducing a range of Cubitron II bonded abrasive grinding wheels to the European market that are claimed to offer an innovative new approach to the grinding process. Employing the highly advanced abrasive grain technology, precision shaped grain, which was introduced with the Cubitron II Abrasive Belts and Discs and is now well established in the market, the new grinding wheels are said to cut faster, last longer and require significantly less pressure than conventional grinding wheels. This results in increased productivity and reduced operator fatigue.

Suitable for heavy weld removal as well as other grinding applications, Cubitron II Bonded Abrasive Grinding Wheels are capable of delivering extremely high cut rates on an extensive range of metals.

David Atherton, senior marketing executive for the 3M Abrasive Systems Division, explains: "This is an innovative grinding technology that cuts faster and lasts longer – tests have shown that the new grinding wheels achieve significantly increased output of conventional products. The introduction of Cubitron II Bonded Abrasive Grinding Wheels from 3M can have a major positive impact on the metalworking industry."

How it works

The irregularity of conventional ceramic grain results in it 'ploughing' through metal, causing a build-up of heat and resulting in a slower cutting rate; this directly affects product durability, potentially resulting in shorter life. In contrast, precision shaped grain technology features precisely-shaped, uniformly-sized and vertically-oriented triangles of ceramic abrasive. These self-sharpening structures fracture as they wear, forming new, super-sharp points and edges that slice cleanly through metal, rather than gouging or 'ploughing', allowing the grinding wheel to stay cool and last longer. This has the potential to deliver significant advantages in productivity and consistency, as well as longer service life.

An additional benefit is that Cubitron II products substantially reduce the amount of pressure an operator needs to apply compared with traditional grinding wheels made from aluminium oxide, zirconia and ceramic grain.

David Atherton continues: "This technology is truly remarkable, allowing operators to increase productivity with considerably less physical effort. These grinding wheels require only one-third of the pressure to produce the same cut. This considerably reduces physical stress on the operators and helps them to remove much more material with the same amount of effort."
