Powder is mixedand suspended in a metal or plastic bonding agent. Ifmetal is used as a bonding agent, the finished productis called metal-bonded or sintered diamond segment.If plastic is used as a bonding agent, the finishedproduct is called plastic-bonded diamonds orpolishing disc. By changing the hardness of thebonding agent, you can change how quickly or slowlythe diamond abrasive is worn down.General PrinciplesGeneral rules for using diamond tools when grindingfollow below. As with all rules, there are exceptions oroccasions when they do not apply.Diamond grit sizeChanging the size of the diamond grit to a smallerparticle/grit size will effect the performance of thediamond tool in the following ways:• Create a finer scratch pattern.• Increased service life of diamond tools.The opposite will occur when changing to a largerparticle/grit size.Hole position Handle height, mm/inchUpper 835/33Center 925/36Lower 1000/39CounterweightsHandlepositionLow, kg/lbsHandlepositionCenter, kg/lbsHandlepositionHigh, kg/lbs1 49/108 51/112 53/1172 43/95 46/101 49/1083 38/84 41/90 45/99CounterweightsHandlepositionLow, kg/lbsHandlepositionCenter, kg/lbsHandlepositionHigh, kg/lbs1 50/110 52/115 54/1192 44/97 47/104 49/1083 39/86 43/95 46/101 |
