Diamond file
technology: through electroplating, Emery adsorbed on the substrate (45 steel) surface.

Feature: abrasion resistance, surface of sand tightly next to each other, no peel off, maintaining sharpness, and long wear.     
Surface finish: matrix parts nickel plated layer, light, polishing, partial finish by sand; granularity to decide, more fine sand, smooth finish, the better. 150-200 mesh
uses:
(1) ordinary flat glass, frosted glass, sandblasted glass, patterned glass, jiasiboli, insulating glass, laminated glass, glass block grinding, particle size between 80 and 120, not easy to edge collapse, fast, after grinding the glass surface clean and clear.
(2) for granite, basalt, limestone, dolomite, sandstone, marble and other stone cutting, grinding, size 36-60, enough to sharpness, grinding speed, long working hours, no edge collapse. After grinding stone and smooth surface.
(3) the colored glaze, underglaze, blue-and-white, powdered Gu Cai, wall tiles, floor tiles, sanitary ware, ceramics, silicate products, polishing of silicon wafers and other materials, particle size between 60 to 80, sharper, shorter working hours, no edge collapse. Polished porcelain products smooth surface.
(4) other metal products to Polish, such as aluminum, stainless steel, etc. If grinding speed steel and tungsten steel, require custom-plated CBN grit, CBN has a sharp comparison.
Size: cover straight spanners (3*140 4*160 5*180), bancuo, oblique flat files and other types of files
