PFERD POLINOX® Convolute Polishing Wheels

POLINOX® convolute wheels consist of non-woven abrasive which is spiral-wound around a core and foamed up. The foam supports the non-woven component and improves its service life and abrasive performance. This particular bond results in non-woven wheels with a very good surface finish, high stock removal rate and long service life.

These properties are particularly apparent when deburring, blending, finishing and polishing soft metals, alloyed and high-alloy steels, in addition to titanium alloys. The wheels can be used on automated appliances and bench grinders, in addition to portable power tools such as straight grinders. By dressing the wheels, they can also be adapted to the geometry of special workpieces.

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.
