Diamond Tools / 339 DIAMOND TOOLS TROUBLESHOOTING DIAMOND BLADE DOES NOT CUT Cause The segments are too hard for the material Solution Check if the blade is suitable for the material Cause The segments have become blunt Solution Sharpen the segments by cutting an abrasive material (e.g. sandstone) Cause Insufficient machine power Solution Check the voltage, machine power & filters EXCESSIVE WEAR Cause The segment is too soft for the material (e.g. if a blade for hard material is used to cut abrasive material) Solution Check if the diamond blade is suitable for the material CRACKING OF STEEL CENTRE Cause The segments are too hard for the material Solution Check if the blade is suitable for the material Cause Excessive cutting pressure, overheating, material slippage, twisting or jamming in the cut Solution Leave the blade to do the work, do not exert too much pressure & allow the blade to cool regularly by leaving it to rotate away from the workpiece for a few seconds LOOSENING OR CRACKING OF SEGMENTS Cause The segments are too hard for the material. This results in the diamond blade bouncing in the cut resulting in cracking segments Solution Check if the diamond blade is suitable for the material SCORCHING OF SEGMENTS Cause Excessive cutting pressure causing overheating. This is easily recognisable from the blue colouring where the segments & the steel core are welded together Solution Allow the diamond blade to cool regularly by rotating the blade away from the workpiece for a few seconds Cause The segments are too hard for the material Solution Check if the diamond blade is suitable for the material. Alternatively use less cutting pressure & let the blade do the work UNDERCUTTING Cause Undercutting occurs when the steel core wears faster than the segment, i.e. where the segment & steel core meet. This is usually caused by materials that are highly abrasive. The cutting debris is not removed sufficiently & the steel core is affected. Undercutting is certain to occur if a diamond blade for hard materials is used to cut abrasive materials Solution Use a diamond blade suitable for the specific material
