Many think Diamond Grinding Wheel are the most suitable product for grinding hard materials. This is not completely true.

Diamond Wheels are the best for grinding Carbide and Glass.

CBN Wheels are the most suitable product for grinding hard steels. CBN wheels last longer and although higher in price they require fewer replacement wheels.

CBN is Cubic Boron Nitride known as a Superabrasive. As the name suggests Superbrasives are stronger than normal abrasives such as Aluminium Oxide and Silicon Carbide.

CBN is highly recommended to grind:

  • Hard Steels
  • Steels over 45 RC hardness
  • Cast Irons
  • Nickel Alloys

CBN is second in hardness to Diamond.

The basic rule is CBN for Steel, Iron and Alloys. Diamond for more delicate items like Glass, Quartz and Ceramics.

Advantages of CBN and Diamond Wheels over conventional Aluminium Oxide and Silicon Carbide Wheels:

  • Fewer wheel changes
  • Less downtime
  • Lower maintenance costs
  • More controlled wear rates resulting in better wheel performance
  • Better consistency
  • Less likely to burn

We always hold a stock of popular Diamond Wheels although as a bespoke product most CBN and Diamond Wheels are manufactured to order

Delivery time is usually 3-4 weeks.
