Cylindrical GRINDING

according to exact dimensional tolerances and surface finishes

In our grinding centre we realise cylindrical grinding according to exact dimensional requirements. The grinding of metal surfaces is carried out in the process of external cylindrical grinding between centres. As part of the surface coating process chain, our grinding shop has special expertise in grinding hard chrome. In principle, all mechanical processing methods can also be requested independently of surface coating.

Grinding Shop

From single-unit production to series production: Depending on requirements, the components are machined on conventional or repeatable CNC grinding machines . By using modern CNC grinding maschines, we are able to realize diameter, form ans position tolerances as well as surface finishes with the highest quality standards. External cylindrical grinding between centers is also suitable for correcting geometrical errors of mechanical parts.

Hard chrome grinding

In surface coating, precision grinding is an important process step in order to optimize the surface quality. As upstream process step, the surface of the base material is ground to improve the coating quality. As post-processing of the coating, the desired surface quality is achieved by precision grinding. In the case of thicker hard chrome layers, components are chrome-plated with excess and then ground to the specified dimension. This concerns components that require particularly high wear protection.

Repair procedures

In combination with our mechanical processing, excess chrome plating is also suitable for the repair or restauration of worn components as well as the build-up through chrome plating of workpieces, which have been ground to measure. This process can be used, for example, to repair cylinders, piston rods and to regenerate turbines. Regeneration is an inexpensive and resource-saving alternative to purchasing new equipment.
