1 Cutting and Grinding Discs echnical Information Durability Resin bonded grinding and cutting wheels for free-hand application must be used within three years of manufacture. Please see metal ring for the expiry date which is specified by month and year; for instance V07/2018. Labelling system for resin bonded grinding wheels Example: Abrasive Grit size A 30/36 V BF ardness Bond Abrasive ype Grit ardness Grade Bond coarse medium fi n e soft medium hard A aluminium oxide M R U BA resin bond C silicon carbide up to up to bis Q S V BF resin bond, fibre-reinforced Z zirconia alumina P Z Working speed LUKAS grinding discs are developed and tested for specific maximum working speeds and grinding processes. Prior to mounting the grinding tool on the machine, it must be ensured that the machine s nominal speed (as specified on nameplate) does not exceed the maximum operating speed indicated on the grinding wheel or disc. Maximum operating speed Diameter of Disc [] /RPM [min-1] m/s m/s

3 Cutting and Grinding Discs Safety With regards to occupational safety and operational convenience, LUKAS responsibility to the customer is taken very seriously. Our products are designed, manufactured and produced in accordance with the most stringent quality standards to provide a maximum of customer value at minimum risk. We are a member of both, the German Abrasive Association (VDS) and the Organisation for the Safety of Abrasives (osa) and thus actively contribute to users health and safety. Applied standards: Safety Requirements for Bonded Abrasives s: EN12413 Safety Requirements for Diamond Blades: EN13236 Safety recoendations Don t handle wheels roughly. Don t use non-reinforced cut-off wheels on portable machines. Don t store wheels in a damp atmosphere or in extreme temperatures. Don t mount a damaged wheel. Don t ever exceed the maximum operating speed marked on the wheel. Don t force a wheel onto a machine spindle. Don t use mounting flanges which are incorrect, damaged, dirty or burred. Don t tighten the mounting nut or locking flange excessively. o do so can distort the flanges and discs. Don t use a machine without a wheel guard. Don t use wheels without proper ventilation or dust protection equipment. Don t apply side pressure to cut-off wheels. You should not bend the wheel. Don t stop the wheel by applying pressure to the periphery or face. Always switch the machine off and allow the wheel to stop revolving. Don t allow the wheel to be trapped or pinched in the cut. Don t apply excessive pressure onto the wheel so that the driving motor slows down. Don t drop or lower a portable machine by the cable or airline onto the floor. A wheel can be easily cracked, if it is put down hard, by the weight of the machine. his is a coon cause of wheel breakage. Don t grind with a depressed centre grinding wheel at an angle below 30 degrees to the work piece. Don t use a machine in a position where you do not have full control of the machine and you are not well balanced. Clamping System he use of flanges with unequal diameters is not allowed. Both flanges between which the bonded abrasive is mounted must have the same outer diameter and similar contact areas (according to EN :2007 and ANSI B.7.1). correct incorrect 170
