Improving Steel Cutting Bit Quality with Diamond-Carbide Inserts

A client had been using an inexpensive imported induction heating system, but ran into quality issues that resulted in production down time. Consequently, they turned to THE LAB at Ambrell to develop the right solution for their application and enable the installation of a reliable EASYHEAT^TM induction heating system. The application involved heating steel cutting bits with diamond-carbide inserts for brazing and de-brazing. Cutting tools were the end product. 

Ambrell's applications engineers determined that a 4.2 kW EASYHEAT would meet the client's objective of heating the part to 1400 ^oF (760 ^oC) within 25 seconds. A specially designed single-turn hairpin coil was developed for this heating application. Along with reliability, the modest size of the EASYHEAT is a benefit as it makes it easy to integrate the system into manufacturing processes such as this one.
