      How to choose proper grinding tools?

       

      Which Bond?


      Resin Bond Diamond&CBN grinding tools

      Resin bonds are based on phenolic or polyimide resins, mixed with abrasive grains and other fillers, glued to the steel or aluminum body. Due to their fast and cool grinding behavior, resin bonds are used in a wide range of application.

       

      Cubic Boron Nitride(CBN) or Diamond?

      CBN has the zinc-blende crystal structure equivalent to diamond, the hardness is a little below diamond.CBN has technological and economic advantages compare to diamond. The hardness of CBN work pieces is as low as 50 HRC but not brittle.

      Diamond is the hardest material know now, with a Moh's harness of 10.Compare with CBN,diamond is used for grinding hard but brittle and short-chipping materials, such as tungsten carbide,glass,ceramics,quarz,graphite and so on.

       

      What is concentration?

      Concentration of diamond grain is calculated by the diamond weight in the diamond layer. For example,C100% means there is 3.3 carats diamond weight in every 1 cm³ of the diamond layer. Diamond concentration is one of the more important parameters of diamond tools, which affectproduction efficiency and cost performance. But it doesn't means the higher of concentration, the better of performance.
