Grinding Wheel - 63 x 8 x 20 RA 60K5V (GW843)

63 x 8 x 20mm (Diameter x Width x Bore) 

Speed (max) - 33m/s (metres per second), 10,000 RPM

 

• Premium quality, high performance wheel with a blend of sharp pink aluminium oxide abrasive.
• Manufacturing process maintains a uniform hardness across wheel diameter.
• Less dressing.- longer wheel life - low grinding force - lower cycle time - minimal thermal load means less burns.
• For hardened high-speed and tool steel.
• Surface, tool & cutter & Internal grinding etc.

 

Surface finish is dependent on grit size. This 60 grit wheel will achieve a minimum surface finish of 14-26 CLA (µinch), 0.35-0.70 RA (µmm).

Corner form radius is dependent on grit size. This 60 grit wheel can achieve and maintain a minimum form radius of 0.50mm (0.020").

 

Pink Aluminium Oxide

 

A premier abrasive wheel which contains a small percentage of chromium oxide. Chromium content allows the grain to splinter giving it a self sharpening effect. Hardness is similar to that of white aluminium oxide. Toughness is greater than that of white aluminium oxide. Outstanding durability with long lasting wheel performance. Typically used on harder steels  which need a cool, friable cutting action to avoid burning. Ideal for grinding a variety of medium and hard to grind high speed and cast alloy steels. Such as high speed cutters, end mills, reamers etc.
