Furnace for Producing Vacuum-brazed Diamond Tools

Our vacuum brazing furnace is engineered specifically for the high-performance brazing of diamond tools and superhard materials, delivering exceptional thermal processing capabilities with a maximum operating temperature of 1350°C. The system guarantees outstanding temperature uniformity (±5°C) within a high-vacuum environment, which is critical for creating oxidation-free, metallurgically sound, and durable joints in diamond tool segments, carbide substrates, and wear-resistant alloys.

Key technical features include a fully metallic hot zone, constructed with molybdenum heating elements and heat shields, to ensure consistent radiant heat distribution and long service life. The furnace is integrated with a high-efficiency vacuum system, comprising a roots mechanical pump and oil diffusion pump, capable of achieving an ultimate vacuum level of 7×10⁻³ Pa to facilitate active brazing in a perfectly clean atmosphere. The entire process is managed by a user-friendly HMI touchscreen interface and a sophisticated PLC-based automatic control system, allowing for precise programming of temperature, vacuum, and cooling cycles. An integrated high-purity inert gas quenching system is available for controlled rapid cooling to optimize the microstructure of the braze joint.

Designed to meet the rigorous standards of the aerospace, automotive, and advanced tooling industries, this furnace is available from stock and can be shipped globally with short lead times to support critical production and R&D demands.
