Surface treatment

We have the staff know-how and the equipment required to give surfaces the desired properties. And when we reach our technical limits, qualified partners who we have been successfully working together with for many years support us.

The highest-quality surface finish, numerous possibilities

Whether it’s grinding, cleaning or abrasive blasting, barrel finishing, laser marking, surface finishing or burnishing: we treat every workpiece with the appropriate degree of sensitivity during the course of surface treatment. Learn more about our range of options here.


    In grinding processes, JEWA offers flat grinding as a stand-alone service. We also cover additional grinding processes with selected partner companies.

    • Flat grinding: 1000 mm x 600 mm x 500 mm


    We use our own fully automated cleaning system and various other systems for part cleaning. We are thus able to optimally meet the wide variety of requirements in industrial part cleaning, and are able to deliver the finished parts with environmentally friendly cleaning.

    • Industrial part cleaning: max. 600 mm x 400 mm x 288 mm
    • Ultrasound cleaning

    Blasting technology

    The use of blasting technologies results in evenly compacted, smooth, satin-finished or glossy surfaces with the desired roughness depth, according to the customer’s wishes.

    • Glass bead blasting
    • Steel-shot blasting

    Barrel finishing/vibratory grinding

    The surfaces, in particular the edges, of predominantly metal workpieces can be removed through barrel finishing or vibratory grinding. This results in deburred or polished surfaces, among others, depending on the customer’s wishes.

    Laser marking

    Using our laser marking system, we can put a barcode, for example, or other markings desired by the customer onto finished parts and assembled components. We are also authorised by the TÜV to carry out restamping of materials and products.

    • Serial numbers, text, barcodes, QR codes
    • Restamping authorisation


    In addition to providing protection against corrosion, burnishing colours components up to deep black. JEWA has its own burnishing system on which we offer quickly and flexibly burnished parts as a service.

    • Burnishing: max. 550 mm x 200 mm x 280 mm
