314 / Super Abrasives SUPER ABRASIVES SUPER ABRASIVES TECHNICAL SECTION CONCENTRATION The concentration is defined by a standard and indicates the weight of abrasive (in carats) contained in 1cm3 of abrasive strip – 1 carat = 0,2 grams. SELECTION OF CONCENTRATION The choice of concentration depends on the machining parameters: * Other concentrations available upon request CONCENTRATION* NUMBER OF CARATS/cm3 ABRASIVE WEIGHT PER cm3 DIAMOND ABRASIVE CBN ABRASIVE* 100 = W 4,4 = 0,88g/cm 3 75 = T 3,3 = 0,66g/cm 3 50 = Q 2,2 = 0,44g/cm 3 HIGH CONCENTRATION MEDIUM OR LOW CONCENTRATION Roughing operations Finishing operation Powerful machine Low power machine Small contact area Large contact area Retention of profile or sharp edges of wheel Cutting without temperature rise OPERATION INTERNAL GRINDING EXTERNAL GRINDING SURFACE GRINDING SHARPENING Diamond 100 75 50 50/75 CBN W T Q Q/T
