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.
