Frequently Asked Questions

What types of diamond grinding wheels does SinoGrind offer?

SinoGrind offers diamond grinding wheels in four bond types: resin bond for superior surface finish, metal bond for heavy-duty grinding, electroplated for aggressive material removal, and vitrified bond for cool grinding. Available in sizes from 100mm to 400mm diameter with grit sizes from 36# to 1200#.

What is the difference between diamond and CBN grinding wheels?

Diamond grinding wheels are used for grinding non-ferrous hard materials like carbide, ceramic, glass, and semiconductor materials. CBN (Cubic Boron Nitride) grinding wheels are designed for ferrous materials including hardened steels, tool steels, and high-speed steels. CBN offers superior thermal stability and chemical inertness to iron.

Does SinoGrind provide centerless grinding wheels?

Yes, SinoGrind manufactures high-performance centerless grinding wheels in resin, metal, and CBN bonds. These are designed for precision throughfeed and infeed grinding of shafts, bearings, pins, and other cylindrical components.

What diamond dressing tools are available from SinoGrind?

SinoGrind offers diamond dressing tools including dressing rollers for CNC grinding machine wheel truing, dressing pins/pens for manual wheel dressing, and dressing cutters for maintaining grinding wheel accuracy and surface finish.

What grinding machines does SinoGrind manufacture?

SinoGrind manufactures CNC external grinding machines (OD grinders) for outer diameter grinding of shafts and cylindrical parts, and CNC internal grinding machines (ID grinders) for inner diameter grinding of bores, holes, and internal surfaces.
