High-Temp Vacuum Brazing Furnace
High-temperature Vacuum Brazing Furnace up to 1350℃ for CBN, PCD,  Diamond tools, Stainless steel, Copper, etc.

This kind of High-Temperature Vacuum Brazing Furnace working temperature can reach 1350℃; Suitable for stainless steel, CBN tools, Diamond tools brazing in the vacuum environment. Due to its high vacuum and high temperature, it can also be used for sintering and heat treatment of other workpieces.

Vacuum Brazing Furnace Features:

  • Stainless steel brazing
  • CBN tools brazing
  • PCD tools brazing
  • Diamond tools brazing
  • Copper / sliver / nickel / aluminium base brazing

Advantages of Our Brazing Furnace:

  • No surface oxidation or discoloration
  • Minimal distortion
  • Flux free brazing
  • Repeatable quality
  • Clean, safe, quiet, and efficient
Due to the slow cooling of the ordinary brazing furnace, the production efficiency is seriously affected. In order to accelerate the cooling rate, our company combined with years of production practice experience developed a vacuum brazing furnace rapid cooling system. The high-temperature nitrogen in the furnace is forcefully pumped out by the vacuum fan, cooled by the cooling water bag, and then sent back to the furnace by the vacuum fan. This rapid cycle leads to rapid cooling.
