Technical advantages of CBN turning tools, as compared to tungsten carbide, ceramics or grinding
- Turning of extremely tough materials that generally had to be ground.
- High cutting speeds and metal removal rates assuring economical applications
- Tool life is substantially increased as compared to sintered carbide and ceramics.
- Outstanding surface finish comparable to ground finish.
- Higher metal removal rate as compared to grinding.
- Possibility of very close tolerance machining due to extremely low tool wear.
- Roughing and finishing cycles possible in one operation.
- Although not replacing the grinding operation in totality, the use of CBN tools has and will eliminate this operation in many cases..
Technical advantages PCD turning and milling tools as compared to tungsten carbide
- Higher cutting speeds, feed rates and cutting depths for very tough materials.
- Roughing and finishing cycles possible in one operation
- Tool life generally 50 times or more than that of tungsten carbide tools
In general, for machining materials such as pearlitic grey cast iron, powdered metals, high temperature alloys and hardened ferrous metals (>45 HRc) where sever interrupted cuts are involved, the higher percentage CBN grade is used.
The higher, percentage ceramic-based CBN can be used for rough and finish machining of hardened ferrous metals (>45 HRc) operations where hard turning is replacing grinding and for continuous as well as interrupted cuts in finish machining.
While using CBN tools, the following guidelines are recommended:
- Use rigid machines with sufficient horsepower
- Keep minimum tool overhang.
- Use negative rake tools and largest lead angles whenever possible.
- Although use of coolant is not mandatory, cutting fluid is generally recommended on long-cut operations.
- A proper chamfer should be ground on the cutting edge to minimise edge chipping and increase edge strength. Larger angles and width may be required for severely interrupted cuts.
- Radius honing is also recommended for severely interrupted cuts

Technical advantages PCD turning and milling tools as compared to tungsten carbide
- Engineering & Machine Tools
- Better surface finish (for brilliant surface finish, natural diamond should be used)
- Roughing and finishing cycles possible in one operation
- Tool life generally 50 times or more than that of tungsten carbide tools
- Lower cutting forces
