How to use diamond polishing pads.
Diamond polishing pads used for grinding and polishing of natural and engineered stone, quartz, concrete, terrazzo, glass. Pads life span greatly depends on the material being processed, worker skill, quantity of water, polisher model ( WET option? adjusted speed option?) . Usually pads with higher grits have longer life span. Low grit ones ( #30, #50, #100) are worn out faster.
Metal bond pads life span usually 2 -2.5 times more compared with resin bond pads, provided that the recommendations for use are observed.
Recommendations for the use of diamond polishing pads:
We recommend to use diamond polishing pads with professional models of angle grinders, possessing adjustable speed and WET options. In most cases rotation speed should not exceed 3000 rpm. When do WET polishing, use low grit pads need add more water, after # 1500, the amount of water must be reduced.
While polishing, particular care must be taken not to overheat the diamond polishing pad. The use of water will extend the life of the diamond tool. Polishing DRY can lead to overheating of the stone surface and pad itself. Overheating could results in smearing (pad leaving color on stone), and glue connecting pad and Velcro could lost its strength, which is dangerous and should be avoided for safety reason. If smearing still happens, then the stone surface must be re-polished starting from # 200, for stone with pigmentation from the pad, re-polishing should starting from # 400.
Doing Dry polishing you should control time and tool temperature, even for DRY pads time should not be too long, to avoid overheating.
The quality of polishing depends which grit # pads used do it, and how thoroughly polishing was done by rough numbers. The polished surface must be washed after each number.
BUFF is used for finish polishing, after # 1500 - 3000. Select Light color BUFF for white stone, and black buff for dark stone and granit , green buff particularly suitable for gabbro.
Diamond polishing pads grit size standard information.
We mark grit for polishing pads (diamond abrasive particles size ) accordingly to European FEPA standard
