Polishing:
Our areas of application


Belt polishing

Industrial polishing or strip polishing can also be carried out as a pre- and post-processing step. After hard chrome plating, industrial polishing improves the appearance and functionality of the chrome layer. The functional advantages of industrial polishing are the reduction of friction and the increase in corrosion resistance.

Teflonizing or TSI post-treatment is a variant of post-treatment.

The micro-cracked chrome surface is sealed with a Teflon coating. Teflon coating can temporarily increase the corrosion resistance.

Belt grinding

Belt grinding is used as a pre- and post-processing method. Before hard chrome plating, it creates an even and smooth substrate for optimum adhesion of the chrome layer.

Belt grinding reduces the roughness of the surface, resulting in a uniform, glossy and functionally optimized surface.

Process flow


The machining process begins with the selection of the appropriate process – depending on the material, component geometry and desired surface quality.

As a rule, the workpieces are clamped between centers and set up for the specific process.

In belt sanding, the component is processed with a circumferential sanding belt. This process is primarily used for smoothing, removing burrs or preparing for coatings. It produces an even surface with good adhesion.

Polishing is carried out as pre- or post-processing. The surface is smoothed and refined using polishing tapes or pastes. The aim is to achieve a visually appealing surface with reduced friction and – depending on the application – improved corrosion protection.

The Superfinish process is also possible as the highest level of superfinishing. Here, a fine abrasive belt is guided onto the rotating component in an oscillating motion. The result is an extremely smooth surface with a high contact ratio and uniform cross-grinding – ideal for tribologically stressed components or precise bearing and sealing surfaces.

In all processes, the surface is finally checked, measured if necessary and the component is carefully packaged.

Depending on the quality requirements, the processes can be used individually or in combination.

Other frequently asked questions about polishing

What is the difference between polishing and superfinishing?

Polishing uses polishing belts or pastes to smooth and refine the metal surface. Superfinishing, on the other hand, uses cross-grinding to create a defined contact area, optimizing lubricant film distribution and tribological properties.

What is the main benefit of polishing

Polishing produces smooth, shiny surfaces, reduces friction and improves the visual appearance and, thanks to TSI post-treatment, corrosion resistance – especially after galvanic coatings such as hard chrome.

Can surfaces be polished without a coating?

Yes, polishing and superfinishing are possible regardless of a coating. They can be used on uncoated base materials as well as on already coated surfaces (e.g. hard chrome).

What is belt grinding typically used for?

Belt grinding is particularly suitable for preparing surfaces – before coating or polishing, for example. It is used to remove burrs, create a uniform structure and improve adhesion for subsequent processes.

What are the advantages of polishing and belt grinding?

Optimum surface quality
Reduced coefficient of friction
Longer service life of components
Improved lubricant distribution
Removal of processing marks
→ Removes burrs, grooves and other residues from previous processing steps.
