ost-effective way to improve the grinding wheel

the best way to improve the cost of: grinding the core of the sheet is not part of the cutting action in a poor quality and low price instead of a secondary abrasive, abrasive cutting quality full performance, lower manufacturing costs.Sheet wheel performance depends largely on the merits of using abrasive quality, good quality abrasives, grinding wheels, high grade, and in the more expensive price. As the domestic high-grade bauxite  green concrete blades resource depletion, a variety of raw materials and coal prices in mid-rise, coupled with energy saving the environment forced shut down, corundum prices are rising fast, from time to time will be in short supply. How rational use abrasives, improve market competitiveness, is the most important enterprises grinding technology considerations.Best approach is to not participate in the core sheet wheel portion of the cutting action of poor quality with low prices instead of secondary abrasive, abrasive cutting quality full performance, lower manufacturing costs. This approach resin bolts and large diameter cylindrical grinding wheel resin grinding wheel has been widely used. For thin grinding wheel, since the intermediate screening, the  polishing pads for granite bottom and the top to separate the feed, if the external and the core are stepwise feeding, in the process to implement quite difficult, is still only vision in the future, if successful, cost reduction, profit improvement , on sheet wheel manufacturing is undoubtedly a far-reaching "technological revolution."Compare prices now wear suitable strategy for various consumer groups, in accordance with abrasive made of different grades of abrasive products, the best abrasive used in most need sheet wheel, avoiding production of low-grade abrasive grinding wheels with high-grade, as far as possible best use, cost-effective in improving the premise, a great effort for each grade of the product have done "extreme."High-grade sheet wheel stable, targeted, reproducible production has generally adopted a sand, special cup grinding wheels  products and even to use zirconium corundum, calcined alumina abrasive and post-processing. The market is dominated by imported products, most cost-effective production of high sheet is not high, not discrimination, targeted not strong, still need further research and development efforts.If you use an ordinary sheet wheel sand, cost is very low, almost no profit, now commonly used two sand instead. The so-called two sand, refers to those standards is not abrasive, aluminum oxide content of about 80% of corundum, good quality two sands, also known as a second, different origin, different batches of two sand quality fluctuation range large. Sand production sheet wheel with two main problems is the wheel performance is unstable, different batches of the same recipe abrasives, grinding wheels produced poor reproducibility, good times and bad
