si fang 4 inch x 5/8 inch pva polishing wheel for metal stone marble glass, silicon carbide pva polishing discs, spongy wheel

?The Marble Polishing Wheel structure is combined with special synthetic resin, which can enhance its wear resistance and grinding force. Moreover, due to the existence of special pores in the Abrasive Grinding Disc grinding wheel structure, the grinding debris can be quickly removed to avoid clogging and heat generation, and it is suitable for long-term grinding work. | ?A mirror-like polishing surface can be obtained – The use of PVA sponge grinding wheel can reduce the grinding cost, improve the grinding efficiency, innovate the traditional grinding process and technology, and improve the grinding smoothness of the product. For example: grinding of various metal surfaces, copper mixing cylinders, cases, watch straps, edges of stone tiles, grinding of marble before electroplating or polishing. | ?The PVA sponge wheel polishing wheel is suitable for grinding marble, glass, travertine, onyx and general masonry materials. Suitable for stainless steel, metal, clock, jewelry, glass and stone industries. | ?Size: Marble Polishing Wheel diameter 4 inches/ 100mm(Note: the diameter of each grit will be larger or smaller than 4 inches, please don’t mind.), hole diameter 5/8inch,16mm, thickness 10mm, max speed 4300rmp. | ?The PVA sponge grinding wheel is usually dry-grinded. The main components are special synthetic resin and silicon carbide abrasive. The binder is soft and slow, leaving no deep flaws on the grinding surface, and can obtain a uniform and smooth surface.
