Vitrified Diamond Grinding Wheel 50-200, Brand Name : XINZUAN

â‘¢ The shape of PDC that is ground by vitrified diamond grinding wheel is very different. The side of PDC project into isosceles trapezoidal that is grind by resin bond diamond grinding wheel.
The base there has diamond layer is much larger than the other end. The side of PDC which is ground by vitrified diamond grinding wheel project into rectangular, the two surface size is the same. The dressing time will reduce when grinding, and the workpiece processing accuracy is high, and the gloss is high. When PDC will be ground by resin bond diamond grinding wheel, there will cutter back-off. This is mainly because resin bond diamond grinding wheel has certain flexible and will concessions when grinding. But the vitrified diamond grinding has large overall elastic modulus, good rigidity, heat resistance, will not cause cutter back-off phenomenon.
④ The workpiece finish is better than that of resin diamond grinding wheel process. Because the resin diamond grinding wheel is not heat resistance, it is easy soft at 200 ℃, resulting in a great brittle, causing the diamond grinding wheel chip. So the grinding wheel is often added more copper powder for cooling, but the extension of copper is large, easy to stick to the PDC around, making the product processing is not bright. The products which are processed by vitrified diamond grinding wheel can reach the mirror gloss, coarse grinding and fine grinding as one process will be completed.
⑤Large feed. If resin diamond grinding wheel use large feed, the parts will not be ground, or the grinding wheel collapse.
In summary, when vitrified diamond grinding wheel grinding PDC product, it has high grinding efficiency, less dressing time, high accuracy of workpiece processing size, good finish, vitrified diamond grinding wheel is the ideal of grinding PDC.
