The Tools & Dies industry relies heavily on cutting tools that can withstand high friction, heat, and continuous mechanical stress. CBN (Cubic Boron Nitride) tools are widely used for machining hardened steel, cast iron, and superalloys, but their performance depends largely on how well the CBN layer is bonded to the tool body.

Traditional brazing methods often cause oxidation, uneven joints, or weak bonding, reducing tool lifespan.

Normantherm solves this challenge with vacuum brazing technology, offering:

  • Clean, flux-free bonding between CBN and metal substrate
  • High joint strength with no cracking or delamination
  • Superior thermal stability for high-speed machining
  • Improved wear resistance and extended tool life

Our vacuum brazing furnaces are designed to handle precision tool manufacturing, enabling toolmakers to deliver higher cutting efficiency and lower replacement cycles. Whether for turning inserts, milling cutters, or boring tools, Normantherm ensures maximum durability and performance with every brazed interface.
