Dressing and truing of grinding wheels

The purpose of the dressing and truing is to restore the original cutting geometry and to correct the flatness and roundness of the grinding wheel. This is done in many cases by diamond dressers.

Abrasives, grinding wheel material

Grinding machines can be equipped with different grinding wheels. The grinding wheels can consist of aluminium oxide Al2O3, cubic boron nitride cBN or diamond. cBN and diamond grinding wheels are very hard and can be used for high precision grinding of very hard parts. The life time is very high. Diamond wheels have some limitation for grinding steel because of the solubility of carbon in iron.

Mesh size

The grain size of the abrasive material of a grinding wheel is determined by the mesh size of the sieve that is used for the selection of the material. The mesh size is therefore a measure of the roughness of the grinding wheel and determines the removal rate and the surface roughness of the workpiece after grinding.

rough medium fine very fine ultra fine
10 12 14
16 20 24
30 36 46
54 60
70 80 90 100
120 150 180 220
240 280 320 400
500 600 700 800
1000 1200 1500 2000
2500 3000 4000 6000


Bonding of the abrasiv material can be vitrified, metallic or resin. Vitrified bonding is used frequently. High stock removal rates can be achieved and the rigidity allows high precision grinding. This bonding is not sensitive to water, acid, oil and it is not temperature sensitive either. Resin bonding is rather soft and is used to achieve very smooth surfaces. Metallic bonding is used for special purposes, e.g. for electrical discharge truing. Regulation and feed wheels use rubber bonding.
