GRONBACH - mechanical surface treatment and finishing

Main page » Technologies » Surface finishing » Mechanical treatments
We process stainless steel from 0.1-1mm – from punching to bending of complex geometries. We bring aluminium from the thinnest foil up to 5mm thick plates or even thicker extruded profiles into the contour desired by the customer. We build all tools and devices ourselves.

We can grind, brush, polish or blast metal surfaces in the most varied degrees of fineness. Turning or milling of metals is also possible. Due to the automated, robot-controlled treatment of the surfaces, each processing is 100% reproducible.

Mechanical surface treatment of stainless steel and aluminium

GRONBACH relies on innovative surface treatments for decorative applications in the material, forming and joining technology of stainless metals such as stainless steel or aluminium. This makes the components more resilient, corrosion-resistant, heat-resistant and conductive. We use the following methods for the mechanical treatment of surfaces:

Brushing and grinding

With these machining processes, the material is removed manually or mechanically by appropriate abrasives and grinding movement in order to achieve the desired surface structure. The ground materials can then be finished in various colours, e.g. using the anodising process, and are protected against corrosion and scratching. Especially when brushing metal or aluminium – fine, dulled or textured surfaces can be produced for high-quality optics.

Blasting

By blasting, the surface treatment is carried out by different blasting media (shot blasting, sand blasting), which are directed onto the material at high speed, e.g. by means of air, liquids or magnetism. This results in a compaction of the material and at the same time the solidification of the surface. In addition, surfaces can be cleaned, machined, matted and finished using this process.

Polishing

The removal of thin layers of the surface removes the smallest burrs, particles, unevenness and impurities. This results in high strength, low adhesion and pure and shiny results of the material.

GRONBACH – Your supplier for surface finishing

We have been processing metals into optical jewellery for over 50 years. They enable the most durable and beautiful surfaces and convince by their exquisite appearance and haptics. Our multitude of grinding media and configuration parameters allows us to meet different customer wishes and surface requirements – from the noble and light appearance of fine grinding to the severity and depth of a coarsely ground surface. We realize your projects both in small series and in large series.

Please feel free to contact us about your project.
