When treating (bending) polished stainless steel tubes the surface is damaged. The Grinding Machine for Tube Bows GRS 33 regrinds the single or the lined up tube bows after bending. Of course straight tubes can be ground with the Machine GRS 33 as well. In both cases the cross-section may be round or oval. The tube bow can be up to approx. 140°. (The exact angle depends on the tube diameter). With respective grinding belts surfaces can be ground of grain size 60 up to grain size 600 (polishing).

Method of Working
The grinding is done with two opposite grinding belts, each of which runs over three pulling rollers being positioned in a grinding head. The tube bow to be ground is put between the two grinding belts. The grinding head rotates together with both grinding belts around the tube bow. To achieve different polished sections there are various grinding belts available. The tube bows can be ground either dry or wet. For wet grinding the machine is equipped with a mechanical cooling pump.

Applications

The Grinding Machine for Tube Bows GRS 33 is suited for grinding of round or oval work pieces, such as tubes or round material made out of stainless steel, iron, aluminum, brass, copper and wood.
