Remove scratches and weld seams, leaving a nice satin finish in just 3 easy steps!

For producing stainless steel containers, switch cabinets or stainless steel furniture usually panels with a so-called industrial finish are used. The production process involves welding, bending, drilling, etc. Scratches can therefore be hardly avoided, and these then have to be removed.

Remove scratches, weld seams in 3 easy steps

Step 1 – Coarse Grinding to removing scratches with a ceramic or zirconium sleeve on an expansion roller.

Remove light scratches with a POLY-PTX® zirconium sleeve grit 80. In the case of very deep scratches on stainless steel we recommend the ceramic sleeve grit 60. Tig welds can be removed using the rubber expanding roller with the POLY PTX pure zirconium sleeve or the ceramic sleeve.

NOTE: Larger welding seams need to be flattened in advance with flap discs.

Step 2 – Intermediate grinding. After the treatment with a zirconium sleeve the surface can be treated with the SC fleece sleeve on an expansion roller. In the next working step the POLY-PTX® SC fleece sleeve (grit size: medium) is used for smoothing the surface roughened by the zirconium sleeve.

Step 3 – Smoothing – The entire surface is reworked through “oscillation” with the POLY-PTX® fleece wheel (grit 80 or finer, we have the largest range of SC fleece wheels from grit 60 up to 900).

Oscillation technique: Through short forward and backward movements in a longitudinal direction and at the same time shifting to the side you achieve seamless, decorative surfaces (industrial finish).
