Aluminium Core Corner Round (CR) CBN Wheels

Recent advances in electroplating technology have made possible the adhesion of CBN particles to aluminium using nickel substrate.

Aluminium Core CR CBN wheels offer advantages compared to Steel Core CBN Wheels.

Aluminium has the same or better tensile strength than steel. Aluminium is easier to machine and therefore can be machined to finer tolerances faster than steel, resulting in a truer running wheel with less tool bounce than on a steel wheel.

Aluminium transfers heat about 7 times faster than steel.  When combined with CBN, which conducts heat 20 times faster than copper to the aluminium, you can sharpen at a cooler temperature with less risk of tool damage compared to a steel wheel.

An aluminium wheel is about 60% lighter in weight than a steel wheel.  This weight reduction puts less stress on the grinder bearings and as there is less kinetic energy the free wheeling time for the grinder to stop is reduced. There is less need to balance an aluminium wheel. The reduced weight of aluminium wheels has the added advantage of lower shipping costs thereby offering more value.

The corner round allows sharpening of complex profiles by laying the tool flat on the grinder tool rest and simply guiding the tool edge along the rounded corner.

The corner round is safer than a sharp cornered wheel in case of accidental body contact.

Metal wheels are much safer than vitrified “stone” wheels as they do not come apart or potentially disintegrate.

Unlike vitrified wheels, CBN wheels do not need to be dressed and the face remains flat and true.

Metal wheels do not wear down and therefore do not reduce in diameter with use like vitrified wheels.  Therefore sharpening jig set-ups remain the same with constant diameter metal wheels resulting faster and more accurate sharpening and longer tool life.
