Grinding (abrasive cutting) Wikipedia

Grinding is commonly used on cast iron and various types of steel. These materials lend themselves to grinding because they can be held by the magnetic chuck commonly used on grinding machines and do not melt into the wheel, clogging it and preventing it from cutting.

GRINDING WHEEL and ABRASIVES BASICS

Friable grit breaks down more easily and is useful for cutting harder materials. Grit size. Grit size typically runs from coarse (16 -24 grit), medium (36 60 grit) and fine (80-120 grit). Superfine grits run from 150 and higher. Grinding wheels usually will be between 24 and 100 grit.

Choosing The Right Grinding Wheel : Modern Machine Shop

Dec 15, 2000 Choosing The Right Grinding Wheel. Hard, brittle materials generally require a wheel with a fine grit size and a softer grade. Hard materials resist the penetration of abrasive grains and cause them to dull quickly. Therefore, the combination of finer grit and softer grade lets abrasive grains break away as they become dull, exposing fresh
