Fengzuan makes diamond and CBN grinding wheels in our own factory in Shijiazhuang, Hebei Province, China. The right wheel depends first on the workpiece: diamond for carbide, PCD, ceramics, glass and other hard, brittle non-ferrous materials, and CBN for hardened steels. Choose your application below to see the recommended bond, shape and specification, then send us your drawing or sample for a quote.
All wheels are made to order in resin, metal (bronze) or vitrified bond, in diameters from Ø10 to 850 mm, grit 80#–3000# and concentration 50–150. Thickness, bore and abrasive layer are made to your drawing or machine spindle.
Carbide Tool Grinding
Tungsten carbide is hard, brittle and sensitive to heat, so the wheel must cut freely without burning and leave a chip-free edge. We supply resin, vitrified and bronze bond diamond wheels for carbide drills, end mills, reamers, inserts, rods and dies. Resin bond is the standard choice for carbide: sharp, cool cutting, wet or dry, with a fine finish. Typical shapes are 1A1 and 12A2 for fluting and gashing, 11A2 for clearance faces, 6A2/6A2T for insert faces and 14E1 for profiles. Wheels for CNC end-mill grinders are made to the wheel pack dimensions of your machine.

PCD & PCBN Grinding
PCD (PDC compact) and PCBN are among the hardest tool materials, so the wheel must keep cutting while holding a sharp edge. We produce vitrified bond and bronze bond diamond wheels for PCD and PCBN cutting tools, inserts and blanks. Vitrified bond is the usual choice: the rigid, porous bond holds edge geometry and is easy to true and dress. 6A2 and 6A2T cup wheels are the most used shapes for insert face and edge grinding, with 1A1 for peripheral grinding and bronze bond where long life and heavy stock removal matter most.

Ceramics & Glass Grinding
Technical ceramics, glass, glass-ceramics, quartz and sapphire chip easily, and the wrong wheel causes edge chipping or fast wheel wear. Bronze (metal) bond diamond wheels give long life, form holding and heavy stock removal; resin bond gives a finer finish with reduced chipping; vitrified bond suits precision forms. Common shapes include 1A1 and 6A2 for surface grinding, 14E1 and 14A1 for edges and profiles, internal wheels for ceramic bores and 1A1R thin wheels for cut-off and slotting.

Hardened Steel & Mold Grinding
Diamond is not suited to grinding steel, because it reacts with iron at grinding temperatures. CBN stays thermally stable on ferrous metals, so we make resin and vitrified bond CBN wheels for HSS tools, tool and die steel, mold steel and bearing steel. Resin bond CBN cuts sharp and cool for tool sharpening and centerless work; vitrified bond CBN holds form and size for internal (bore) grinding and production work. Typical shapes are 11A2/12A2 for HSS tools, 1A1 for mold and die surfaces, 1A8/1A1W internal wheels for bearing rings and 14E1 for profiles.
