POLINOX® unitized discs
POLINOX® Unitized Disc
POLINOX Unitized DiscPOLINOX® 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 featuresCost-effective due to high abrasive performance and durability.Produces very good surface quality.Can be profiled as desired, enabling optimal adjustment to the contour.ApplicationsCleaningDeburringStep-by-step fine grindingRougheningStructuring (matt finishing, brush matting and satin finishing)Surface workMaterials that can be workedStainless steel (INOX)Steel materials with a hardness > 54 HRCSteels up to 370 HV (< 38 HRC)ThermoplasticsTitaniumTitanium alloysZincAluminumBrassBronzeCast steelCobalt-based alloysCopperFibre-reinforced thermosetting plastics (GRP, CRP)Hardened, heat-treated steels over 370 HV (38 HRC)Nickel-based alloys (e.g. Inconell and Hastelloy)Recommendations for useConsiderably 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.SafetyFor safety reasons, the maximum permitted rotational speed indicated must never be exceeded.Technical informationVersionMH (medium-hard)Dia.
