2010. 3. 8. GRADE(STRENGTH OF BONDING) The relative holding power of the bond which holds abrasive grains within a wheel-degree of "hardness" of strength is indicated softer grades in low alphabet and harder grades in high alphabet. Abrasive grains of same size but with heavier bond coating and thicker, stronger bond posts as in a hard grade wheel.

Grinding Wheels Types, Material & Specifications
Wheel Grade. This determines the tightness of the bonds holding the abrasives. The wheel grade affects all the considerations of grinding. This includes wheel speed, coolant flow, feed rates, and grinding depth. Grain Spacing. This depends on the spacing of the structure. It determines the ratio of the bond and the abrasive to the air space.

TECHNICAL SOLUTIONS FOR CUTTING & GRINDING
Cold grinding Up to 300°C 300ºC 500ºC 700ºC ºC INTRODUCTION Before further processing semi-finished steel products, the workpiece should be free from scale and flaws. High-pressure grinding is the optimal process for removing scale, cracks and other surface defects. Grinding large-scale rounded parts however, requires specific grinding facilities.
