Learn all about Diamond and CBN Superabrasives
PBR Diamond & CBN Electro-Plated Tools are available in a wide range of forms and contours. Diamond and CBN Electro-Plated Wheels provide high stock removal and high efficiency for free cutting of Hardened Steels, Non Ferrous Metals, Ceramics and Composit
There are two types of Superabrasives Diamond and CBN.
DIAMOND SUPERABRASIVES
Diamond is the hardest material known to man and has unsurpassed resistance to wear. Industrial diamond used in wheels will either be natural or synthetic.
Diamond superabrasive grinding products have been developed for high precision and difficult to grind applications and materials which include Ceramics, Carbide, Glass, Stone and sintered materials.
The requirements for higher quality, longer life and faster grinding cycles from machine tools are the key reasons for using superabrasives with traditional grinding wheel products.
Diamond superabrasives are available in a wide range of grit sizes.
- Grit size is available
- Coarse D181 to D126
- Medium D107 to D76
- Fine D64 to D54
- Extra Fine D46 to D25.
Electroplated wheels often use grit sizes considerably coarser to achieve greater metal removal when grinding carbide.
Diamond wheels are manufactured in 4 concentrations 50/75/100 and 125. 100 concentration is equal to 4.4 carats of abrasive per cubic centimetre. Other concentrations are proportional.
Most commonly used shapes are readily available and non-standard products can be manufactured to suit specific applications.
BOND TYPE
This is dependent upon the application and we request as much application detail as possible to allow us to recommend the most suitable bond.
CBN SUPERABRASIVES
CBN (Cubic Boron Nitride) is the second hardest superabrasive. CBN superabrasives are made from man-made material and were developed specifically to grind ferrous materials such as Steel, Hardened steel / Tool steels and Steel Alloys.
Longer life and faster grinding cycles are the key advantages when comparing CBN superabrasives with traditional grinding wheel products.
CBN superabrasives grit sizes are available as Coarse D181 to D126, Medium D107 to D76, Fine D64 to D54 and Extra Fine D46 to D25.
CARBIDE GRINDING WHEELS
Carbide grinding wheels are manufactured in light green silicone carbide abrasive. This is a very sharp friable abrasive used on carbide, non-ferrous materials and non-magnetic stainless steel.
Grain sizes are available Extra Coarse 16/20/24, Coarse 30/36, Medium 46/54/60 and Fine 80/100/120/180, Extra Fine 220/240/280/320/400.
DIAMOND GRINDING WHEELS
Diamond grinding wheels are also termed as superabrasives.
Diamond grinding wheels are used to grind Carbide, Ceramics, Glass, Fibreglass and Stone.
Grit size is available Coarse D181 to D126, Medium D107 to D76, Fine D64 to D54 and Extra Fine D46 to D25.
