POLINOX® convolute wheels consist of non-woven abrasive which is spiral-wound around a core and foamed up.
Varied application options, for example: Rounding of edges, Fine grinding of implants, Weld dressing of intersections on turbine blades, Removal of processing traces on surgical instruments, Create matte surface finishes.The foam supports the non-woven component and improves its service life and abrasive performance. By dressing the wheels, they can also be adapted to the geometry of special workpieces. This particular bond results in non-woven wheels with a very good surface finish, high stock removal rate and long service life.
