Diamond abrasive was initially used for ceramic tiles polishing. Compared with traditional silicon carbide abrasives, this product’s advantages can be summarized as following: 1) long working lifetime, approximate 80-140 times longer than traditional silicon carbide abrasive. 2) grinding efficiency is increased more than 50%, the electricity consumption of polishing spindles is eased by more than 35% and the polishing speed is increased more than 20% 3) maintenance cost of polishing spindle and belt is reduced about more than 30% 4) waste residue caused by grinding is reduced to even less than 1% of that produced by traditional silicon carbide abrasive, which can be neglected. 5) operator’s workload is visibly reduced then save labor cost 6) save related social resources due to required abrasive transportation quantity reduced, such as energy and logistics,etc.
