PCD and CBN cutting tools are widely used in metal cutting and processing nowadays. The quantity demanded has a 20 times increased in last 5 years. To fit the social more complex needs and rapid development of science and technology, tools manufacturer’s demands for higher precision and better grinding efficiency are also increasing as well. “More Super Hard Products” devotes to offer an efficiency and economic solution in PCD and CBN cutting tools grinding.
Improved bond systems
Besides choice of the correct diamond girt, the bond system is the key to get superior grinding result. Great effort is made to innovate and improve the previous bond system. Several exclusive bond system lines (no porosity series, high porosity series) are offered to meet different grinding purpose.
Super-fine girt size available
With the demand of extremely smooth cutting edge, we recommend super-fine grit size wheel to customers. D3(4000#) and D7(3000#) grit size now are available, they provide you superior cutting edge chipping <5 μm.
Features of vitrified diamond grinding wheel
