Electroplated dimond emery strips
The size of diamond emery strip is longer than conventional sanding belt, both sides need to leave extra uncoated dimensions for import and export. Electroplated diamond emery strips are used to solve the difficult-to-grind materials such as stones, glass, ceramics, metals, carbides and composites.The sharp-cut diamond minerals and flexible backing make this abrasive a good match for use in a variety of metal processing applications .

Features of Diamond emery strips
* More embedding depth, less exposure
* Grinding belt does not move parts
* Shortcomings: diamond particles are easy to fall off, do not require grinding allowance.
* Wet grinding effect is good

Example Parameters of diamond sanding belts for HVOF WC coating
Diamond sanding abrasive belt is a kind of coated abrasive tool, which is superhard material (synthetic diamond) abrasive particles adhesive to the flexible base by bond. And can be divided into metal nickel plating electroplated bond and resin bond, resin bond also consists flexible and hard type. In some sense The grinding by diamond sanding belt for thermal spray coating industry can replace that of diamond grinding wheel and film polishing. Diamond sanding belt can complete the grinding and polishing process. Recently, it is widely used in thermal spray coating industry, the production and repair of hydraulic cylinder and turbine blade.

Moresuperhard CBN sanding belt	50x1500mm 4000# 50x1500mm 800#
First test (50x1500mm 4000#)	The belt is little bit too stiff for small belt grinder, but work well and customer satisfy with surface finish
Second test (50x1500mm 800#)	It is thinner and much flexible than 4000#
