Size Of Grinding Wheel

- Sep 15, 2017-

There are many kinds of grinding wheel, each have their own different application, manufacturing process and binder is different, so each kind of grinding wheel will be their own characteristics and different applications. Below, we will explain the abrasive and particle size of the grinding wheel.

Particle size

The size size of the abrasive grains is called granularity. Particle size is divided into coarse-grained and fine-grained, particle size classification is generally used sieving method, for example, particles can pass through 60 holes in the sieve called small particles, that is, fine-grained, can pass through 40 of the screen mesh, called large particles, is coarse grain size. Sometimes it's medium-grained, and some are called micropowder. The particle size of the grinding wheel has a great influence on the surface finish and machining efficiency of the workpiece. Coarse grinding, large grinding, grinding efficiency is very high, but the workpiece surface is relatively rough, not so smooth, abrasive fine, grinding more evenly, the workpiece surface is relatively smooth, but the cutting volume is not so large, Thus the grinding efficiency is lower. The selection can be considered from workpiece surface finish requirements and grinding efficiency.
