PFERD Tools for Use on Aluminium

<strong>PFERD</strong> <strong>Tools</strong> – Catalogues 201-209Catalogue 204 – Grinding and Polishing <strong>Tools</strong>Fine grinding and polishing tools are suitable <strong>for</strong> pre-grinding, deburring,chamfering, fettling, fine grinding, texturing and polishing operations onaluminium and its alloys in machinability groups SOFT, TOUGH and harD.The tools which are suitable <strong>for</strong> machining aluminium can be summarized ingroups:■■Coated abrasive tools■■Non-woven abrasive tools■■Bonded abrasive tools■■Polishing toolsCoated abrasive toolsin Catalogue 204:■■Abrasive spiral bands■■POLIROLL ® , POLICO ®■■Fan grinders, flap wheelsand flap rolls■■COMBIDISC ® grinding discs■■Special tools■■Short and long belts■■Economy rolls andsheet material■■Fibre discs andvelcro-backed abrasive discs■■COMBICLICK ® fibre discs■■Grinding oil 412 ALUCoated abrasive toolsCoated abrasive tools, with a cover bond actively supporting the grinding process,are suitable <strong>for</strong> use on aluminium surfaces. The additional cover layer cools theworkpiece and prevents aluminium from adhering to the spaces between abrasiveparticles. Silicon carbide (SiC) is highly suitable <strong>for</strong> use on aluminium due to theshape of its grains. Depending on grit size, coated abrasive tools can provide highremoval rates (e.g. during chamfering with 36 grit fibre discs) or a very fine surfacefinish if a fine-grained abrasive is used (e.g. pre-polishing with a 320 grit fangrinder).The service life of coated abrasive tools can be greatly extended through the useof our grinding oil 412 ALU. This oil prevents chip particles from adhering to theabrasive surface and thereby prevents loading problems.Activegrinding layerStructure of coated abrasiveproductsBackingmaterialBasic bond Top bond AbrasiveparticlesNon-woven abrasive toolsin Catalogue 204:■■COMBIDISC ® non-woven discs■■COMBICLICK ® non-woven discs■■POLINOX ® mounted points,wheels and drums■■Special tools■■POLIVLIES ® discs■■POLIVLIES ® self-adhesive discs■■POLICLEAN ® tools■■Short belts, non-woven typesNon-woven abrasive toolsThe very open structure of the non-woven abrasive material prevents loadingand heat build-up during grinding. Non-woven abrasive tools are excellent <strong>for</strong>producing fine and ultra-fine finishes, light cleaning, removing oxide layers, andcreating surface textures.Structure ofnon-wovenabrasiveAbrasive gritSynthetic fibresResin30
