POLINOX® unitized discs are used for face-down grinding with variable speed angle grinders. Ideal for larger surfaces. The compressed, non-woven material is bonded to a fiberglass back. POLINOX® unitized discs are made of multiple heavily compressed, non-woven layers, which are bonded together by a special grain/resin system. The different combinations of compression, fibers, grain, and the appropriate bond create non-woven products that offer a very good surface finish, high stock removal rate and long tool life. These tools can be used for a wide range of work on surfaces, from relatively coarse grinding to preparing the surface for polishing. Medium-hard version with increased edge strength and service life for coarse deburring and cleaning applications.

Special features

  • Cost-effective due to high abrasive performance and durability.
  • Produces very good surface quality.
  • Can be profiled as desired, enabling optimal adjustment to the contour.

Applications

  • Cleaning
  • Deburring
  • Step-by-step fine grinding
  • Roughening
  • Structuring (matt finishing, brush matting and satin finishing)
  • Surface work

Materials that can be worked

  • Stainless steel (INOX)
  • Steel materials with a hardness > 54 HRC
  • Steels up to 370 HV (< 38 HRC)
  • Thermoplastics
  • Titanium
  • Titanium alloys
  • Zinc
  • Aluminum
  • Brass
  • Bronze
  • Cast steel
  • Cobalt-based alloys
  • Copper
  • Fibre-reinforced thermosetting plastics (GRP, CRP)
  • Hardened, heat-treated steels over 370 HV (38 HRC)
  • Nickel-based alloys (e.g. Inconell and Hastelloy)

Recommendations for use

  • Considerably reduce peripheral speed for work on materials with poor heat-conducting properties, e.g. titanium and stainless steel.
  • For the best performance, use with a recommended peripheral speed of 3,000-6,000 SFPM. This provides an ideal compromise between stock removal rate, surface quality, thermal load on the workpiece and tool wear.

Safety

  • For safety reasons, the maximum permitted rotational speed indicated must never be exceeded.
