The art of precision grinding


The triangular Structure Revolution

Cutting Capabilities of 3M™ Precision Shaped Grain
With the 3M™ Cubitron™ II* griding wheels, 3M engineers have for the first time managed to bond to a grinding wheel synthetic grains with geometrical defined cutting edge.

This new grain is called 3M™ Precision Shaped Grain. When used in combination with new generation of vitrified bond technology, the risk of thermal damage is virtually eliminated.

3M™ Cubitron™ II* grinding wheels are made up of “geometrically defined cutting edges” (3M™ Precision Shaped Grain). Every grain is exactly the same engineered shape.

Individualy formed chips

This is a grinding process without the use of coolance. Unlike conventional grinding wheels, the geometrical defined cutting edges  generates long, uniform and well delimited sparks.


No risk of thermal stress

Because the chips are immediately removed, no thermal stress can ocurre between the grinding wheel and the workpiece.

Sharp cutting, no obstructions

In conventional abrasives, obstruction occurs when the wheel passes. Thanks to the sharp cutting of the 3M™ Precision Shaped Grain, the chip jumps freely, similar to the operations of milling, only that a much lower scale. There is no longer an obstruction that slows the wheel and generates heat.

3M™ Metal hybrid bonded diamond grinding wheels 6PHN with NF-Bond

With the products known to date, low cutting depths and feed rates were required in order to protect the workpiece and the tool against thermal damage. The 3M™ 6PHN with NF-bond, though, are ideal for fast deep grinding. They have already proven their removal performance with simultaneously high stability in a wide variety of applications. These wheels are especially suitable for high performance machines.

The cutting capability of synthetic resin and ceramic bonds with the profile resistance and the stability of metal bonds make the 3M™ 6PHN with NFMax-Bond the perfect grinding tools for producing flutes. Due to its outstanding grinding properties when deep grinding with very high removal rates and simultaneously low wear, the new generation is especially well suited for grinding large contact surfaces, at high material removal rates, and workpieces with diameters from 10 to 20 mm.

3M™ Resin bonded diamond grinding wheels 6PBP

Special resins and the addition of innovative additives lend those grinding wheels great flexibility with simultaneously high edge stability. These wheels are therefore suitable for flute grinding when manufacturing tools as well as when resharpening them. These wheels are especially suitable for sharpening worn tools on high performance machines.
