They feature diamond particles in \nraised patterns provide increased cutting rates, enhanced \ncooling and efficient removal of debris. They are extremely \ndurable, and provide excellent edge retention and sample \nflatness. Wide, low-profile tabs along the perimeter of the \ndisc allow easy removal after use. \nDia-Grid RIGID discs are available with magnetic or adhesive \nbacking. Magnetic back disc item numbers end in “M.” \nWarning! \n•\nDo not start platen rotation until the disc is firmly fastened to the platen.\n•\nKeep hands, fingers and body parts away from moving edges to avoid injury.\n•\nTurn off platen rotation and wait for the platen to completely stop before attaching\nor removing the Dia-Grid RIGID disc.\nGrade \n8" (200mm) \n10" (250mm) \n12" (300 mm) \n120 Grit \n50-70805M\n50-71005M\n50-71205M\n50-70805\n50-71005\n50-71205\n220 Grit \n50-70810M\n50-71010M\n50-71210M\n50-70810\n50-71010\n50-71210\n600 Grit \n(P-1200) \n50-70820M\n50-71020M\n50-71220M\n50-70820\n50-71020\n50-71220\nLife Expectancy \nProduct life will vary depending upon factors such as frequency of use, size and type of \nsamples, and the number of samples being ground. White wear indicators will appear when the \ndiamond is completely worn from each segment; the disc should be replaced once the \nindicators appear. \nCleaning \nClean Dia-Grid RIGID discs by applying water and soap to the surface; for more aggressive \ncleaning, scrub the disc with a stiff non-metallic brush. After cleaning, it is recommended to \nspin-dry the disc to remove most of the water from the surface before storing it. \n\n\nPage 2\n2 of 2 \nUsage Guidelines \nUpon initial use, the Dia-Grid RIGID disc will take about 6-10 minutes of operation before \ngrinding at its highest efficiency. \nOnly water should be used for grinding; the use of any other lubricants may produce \nundesirable effects. Allied High Tech Products assumes no responsibility for damages resulting \nfrom misuse. \nThe optimal material removal rate is achieved at 300 RPM with an applied force of \n6-8 lbf (27-36 N) for each 1.25" (32 mm) ø mount. Samples that take up more area of the\nmount may require greater forces to maintain efficiency.\nDressing \nIt is normal for the encapsulating resin and/or sample debris to build up and clog the diamond \nabrasive (Figure 1), reducing its effectiveness and diminishing its capability to remove material \nat the same rate after numerous cycles. A white, aluminum oxide dressing stick (# 60-20108) is \nsupplied with each disc to remove build up. Contact Allied to purchase a replacement dressing \nstick. \n1. Prior to use, soak the dressing stick in water for\n3 minutes.\n2. Fasten a Dia-Grid RIGID disc to a platen.\n3. Keep hands clear of the edges of the disc and\nactivate clockwise platen rotation at 100-200 RPM.\nTurn on flowing water as a lubricant.\n4. Using both hands, hold the dressing stick\nlengthwise and apply firm pressure to the side of\nthe disc that rotates away from the user.\nSimultaneously, move it from the center to the\nedge of the disc (Figure 2). Dressing times\ndepend upon the elapsed time between\ndressing operations.\n5. Stop the platen completely. Then remove and wash the disc thoroughly to remove the\ndislodged debris and aluminum oxide particles. For more aggressive cleaning, scrub the\ndisc with a non-metallic brush.\nFigure 1: Left: Debris buildup on diamond segments Right: Same location after dressing \nFigure 2: Apply the dressing stick to the side of the \ndisc that rotates away from the user.
