Product Details
Equipment Description
Ultra-Hard Tool Vacuum Brazing Furnace refers to the heating of the workpiece in a vacuum chamber, and is mainly used for welding products with high quality requirements and easily oxidized materials. The vacuum brazing furnace includes a pressure vessel with a cylindrical side wall and a door. The size and position of the door are designed to close one end of the cylindrical side wall. The workpiece processing system is installed on the pressure vessel door to support metal workpieces for heat treatment or brazing. The workpiece processing system includes a device that rotates the workpiece during processing. The vacuum system can be connected to the workpiece so that the pressure inside the workpiece is lower than atmospheric pressure during the brazing process.
Features
Because Ultra-Hard Tool Vacuum Brazing Furnace does not use flux, it significantly improves the corrosion resistance of the product, avoids all kinds of pollution, pollution-free treatment equipment costs, and has good safe production conditions. It not only saves a large amount of expensive metal fluxes, but also does not require complicated flux cleaning procedures, reducing production costs. Vacuum brazing solder has good wettability and fluidity, which can weld more complex and narrow-channel devices, improve the yield of products, and obtain a firm and clean working surface. Compared with other methods, the internal structure of the furnace and fixtures have a long life, which can reduce the maintenance cost of the furnace
