Surface grinding wheels

For surface grinding of work pieces, different versions of grinding wheels can be used, which have to be adapted to the grinding machine type and for the application.

Grinding wheels for double side surface grinding

Surface grinding machines are available in several versions. Single disk grinding machines use a rotary table to mount the parts while usually a vertical spindle grinding wheel is grinding the parts. On the same machine and using the same rotary table, also two spindles can be mounted, e.g. for coarse grinding and for fine grinding. Double disk surface grinding machines use either horizontal or vertical spindles and the metal parts are ground same time from both sides. Many different types of part feeding and automation are available.

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.

Bonding

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.
