Vacuum Brazed CBN Tools — Enhancing Durability in the Tools & Dies Industry
Normantherm•10/13/2025
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.
An ion source sampling cone sits at the front line of mass spectrometry. It faces high temperatures corrosive gases and constant mechanical stress. The weld quality determines whether the cone delivers accurate results or becomes a source of contamination and drift.
Beryllium copper is a high-performance copper alloy widely used in industries requiring a unique combination of electrical conductivity, strength, elasticity, and wear resistance.
Silver contacts on silicon nitride ceramic heating plates take a beating. High temperatures thermal cycling and mechanical stress eventually take their toll. When the contact degrades heating performance suffers.
