Grinding Wheels

    1. Resin Bond Grinding Wheels (Diamond Wheel, CBN Grinding Wheel)Our resin bond diamond and CBN wheels are available flat, cup shaped, bowl shaped, and a cylindrical shape. These bonded abrasive products can be used to sharpen cutters on various materials, slotting axis parts, cutting quartz and glass, grinding end faces, and the internal bore of metals.
    1. Electroplated Diamond Wheels, CBN Grinding WheelsThis grinding tool can be used in both medium and large batches of grinding and forming projects, working as an excellent grinding wheel dresser with a high precision, high efficiency and low cost.
    1. Slotting WheelsIt is primarily used for cutting or slotting of oxidation film with a high content of A12O3 or a metal oxide film resistance. During the slotting process, the diamond cutting disc requires no enforced cooling conditions, providing a high precision, a narrow slot and a long service life.
    1. Back Grinding Wheels

      This particular grinding tool comes in two types: a silicon wafer back grinding wheel and an LED substrate back grinding wheel. Both of them can be used on different grinding machines made in Europe, America, Japan, and China. They also feature a stable performance ...

Hongtuo's grinding wheels include CBN grinding wheels anddiamond wheels. Basic characteristics of these abrasive wheels include each featuring a high hardness, a high thermal conductivity, and high sharpness. In comparison to common grinding wheels, CBN and diamond grinding wheels offer a higher abrasive cutting efficiency. Because of that,this bonded abrasive tool is suitable for high efficiency and high rate grinding in modern machining works.

Hardness comparison of various abrasives is as follows

If you wish to purchase grinding wheels from us, apart from the basic size, we need to know the abrasive particle size, density and bonded agent type.
