Introduction

Vacuum Brazing Furnace is excellent for brazing ultra-hard materials(PCD/PCBN/MD/ND/CVD),tungsten carbide,ceramics and others, it’s fully automatic and very easy to operate at high efficiency.
Materials: Natural diamond, Monocrystal diamond, PCD,PCBN,CVD and cerment.
Substrate material: Cermet, tungsten carbide,steel, stainless steel, steel alloy, ceramic,etc.

This vacuum brazing machine is a special welding equipment designed for superhard tools and wear-resistant parts. It uses high vacuum (≤10⁻³ Pa) or controlled atmosphere environment, combined with precision temperature control (up to 1200℃) and pressure system to achieve high-strength connection between PCBN and cemented carbide substrate.

Its core advantages include:

Oxidation-free brazing: vacuum environment avoids high-temperature oxidation of materials and ensures pure interface.

High-precision temperature control: multi-stage program temperature rise (±1℃ accuracy) to match the melting characteristics of brazing materials (such as Ag-Cu-Ti).

Pressurized brazing: optional axial pressure (0~10 MPa) to improve the density of the brazing seam.

Application Mainly used for high-strength brazing of super-hard tools and wear-resistant parts to ensure oxidation-free connection and improve tool life and processing accuracy.
