Carbide Tipping is specific brazing process by which a hardened tip material is applied to a base material to produce an extremely hard cutting edge. Additional information about Induction can be found below.
Carbide tipping is a specific brazing process by which a hardened tip material is applied to a base material to produce an extremely hard cutting edge. When using induction heating, the tipping material is brazed to the base material with temperatures up to 1900F (1037C). A carbide tip is more durable and holds its sharpness 10-20 times longer than a standard steel edge.
Typical materials for carbide tipping include: steel to tungsten carbide, poly-crystalline diamond, or cubic boron nitride. Carbide tipping is commonly used to manufacture cutting tools such as wheels, mining tools, saw blades, drill bits, and lathe tools. Some of the benefits achieved by using induction for carbide tipping, include:
- Reduced part variation and improved process control
- Better process throughout by enabling large volume production without large batch sizes
- Precise heating
- Better joint quality and fewer part rejects
- Reduced oxidation and acid cleaning
- Faster heating cycles
- Safer than using flame brazing
- Lower cost than operating a batch or furnace process
