Diamond and CBN Wheels are made according to International Standards and Customers' Drawings.Resin Bonds are known for high cutting efficiency. Resin Bonds are used in dry and wet grinding on both manual and automatic feed grinding machines. The required properties are achieved by the phenolic resins. Metal Bondsare meant for high resistance to wear. Metal Bonds tend to give particularly long life, but are generally inferior to resin bonds with regard to material removal rate. The use of coolant for metal bonds is a must. In exceptional cases of small contact surfaces, dry grinding may be employed.
