Fengzuan makes three families of production grinding wheels for cylindrical work: internal grinding wheels for bores, centerless wheels for rods and pins, and 1A1 parallel (straight) wheels for surface and cylindrical grinding. All three are available with diamond or CBN, in resin or vitrified bond, made to your machine and drawing.

Internal Grinding Wheels (1A8 / 1A1W)
Small-diameter wheels, from Ø10 mm, for internal (ID) grinding of bearing rings, bushings, gears, carbide dies and hardened sleeves. Available in resin bond and vitrified bond, with CBN for steels and diamond for carbide and ceramics.
Vitrified CBN internal grinding wheels
Vitrified CBN holds size over many parts and can be dressed for accurate bores in hardened steel.
Resin bond internal grinding wheels
Resin bond internal wheels cut sharply with a fine finish, suited to carbide and tool bores.
Centerless Grinding Wheels
Resin bond diamond and CBN centerless wheels for through-feed and in-feed grinding of carbide rods, pins and hardened steel parts. The wheel width and diameter are made to your centerless grinder.
1A1 Parallel (Surface) Grinding Wheels
1A1 parallel wheels, sometimes called straight or P-series wheels, for surface grinding and cylindrical grinding. We produce resin bond parallel wheels in diameters such as 300 and 650 mm and vitrified bond parallel wheels in diameters such as 200, 300 and 350 mm.
Applicable Workpiece Materials
- Tungsten carbide rods, blanks and dies (diamond)
- Ceramics and glass (diamond)
- Bearing steel, HSS, tool and die steel (CBN)
- Hardened alloy steel components (CBN)
Bond Advantages
- Resin: sharp cutting, self-dressing, fine finish for centerless and parallel grinding
- Vitrified: controlled porosity, profile and size holding for internal grinding
