The art of precision grinding
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.
Extreme material removal rates
Low risk of thermal damage
Considerably reduction of wheel dressing
Wheel life about four times longer

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.

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.
Because the chips are immediately removed, no thermal stress can ocurre between the grinding wheel and the workpiece.
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.
Design freedom
Higher productivity
Increased stability
in your ID grinding process
Complex grinding requires innovative solutions. Armed with additive manufacturing technology, 3M has developed a groundbreaking new solution in precision internal diameter grinding. New 3M™ Precision Structured Vitrified CBN Grinding Wheels are 3D printed, layer by layer, to help you reach higher dimensions of performance in cylindrical grinding.
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.
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.
Our technicians can help you optimize your processes to reduce costs and delivery times, thereby improving customer satisfaction.
