High Temperature Vacuum Brazing Furnace for Diamond tools brazing
The equipment is mainly applied to copper, nickel, gold, stainless steel, automobile oil cooler, plate fin titanium alloy radiator, automobile EGR, automobile exhaust gas recirculation system heat exchanger, diamond tools, diamond hole opener, diamond grinding wheel, diamond blade, diamond carving knife, diamond grinding head, diamond saw blade, diamond grinding wheel, diamond roller, diamond roller, diamond edging wheel, diamond grinding disc Diamond bowl mill, diamond grinding blade, diamond sawing tool, diamond circular saw blade, diamond row saw, diamond rope saw, diamond cylinder saw, diamond band saw, diamond chain saw, diamond wire saw, cemented carbide vacuum brazing, cemented carbide drilling tools, diamond finishing tools, diamond tools, geo metallurgical bits, oil (gas) well bits, engineering thin-wall bits, stone bits, glass bits and other high-temperature alloys Especially vacuum brazing of aluminum and heat-resistant alloys. It is also suitable for welding zirconium, niobium, molybdenum and other refractory alloys or dissimilar metals. In the process of vacuum brazing, the parts are in a vacuum atmosphere, and the products have the advantages of no oxidation, no pollution, small deformation, no flux, no porosity, slag inclusion, and no corrosion to the workpiece. It is an efficient process means to realize multiple brazing joints and multiple components welding at the same time.
We have developed and produced vertical, horizontal, top and bottom doors.
Vacuum brazing technology can realize the chemical metallurgical bonding between diamond, bond (brazing alloy material) and metal matrix interface, and has high bonding strength. Due to the high bonding strength on the interface, only a very thin bond thickness is required to firmly hold the abrasive particles, and the exposed height can reach 70% ~ 80%, which makes the abrasive materials more fully utilized and greatly improves the tool life and processing efficiency. Compared with the traditional technology, the maximum allowable cutting edge value of diamond tools can be increased by more than 50%, and the diamond consumption per unit volume of workpiece material can be reduced by more than half under the condition that the power consumption of the tools does not increase or decreases. Compared with electroplating tools, it also shows incomparable advantages.
