The abrasive vacuum brazing furnace is a specialized welding equipment used in the manufacturing process of abrasive tools. It melts the brazing material by heating in a vacuum environment, thereby achieving the connection between the abrasive and the tool base.
Product Overview:
The abrasive vacuum brazing furnace is mainly used for the brazing process of abrasive tools, such as the manufacturing of diamond or cubic boron nitride (CBN) tools. The equipment usually has precise temperature control and vacuum regulation functions to ensure the quality and efficiency of the brazing process. During the brazing process, the abrasive particles are fixed onto the tool base, forming a solid connection.
Product Features:
1. High Vacuum Environment: Provides a high vacuum environment to reduce oxidation and impurities, ensuring the quality of brazing.
2. Precise Temperature Control: Precisely controls the heating temperature to meet the melting point requirements of different brazing materials.
3. Uniform Heating: A large area heat exchanger and internal and external circulation fans ensure the uniformity of the furnace temperature, reducing workpiece deformation.
4. Multi-zone Temperature Control: Vacuum partition pressure/multi-zone temperature control function, suitable for the brazing needs of complex workpieces.
5. Efficient Cooling System: Equipped with an efficient cooling system that can quickly cool the workpiece to room temperature, improving production efficiency.
6. Reliable Furnace Structure: The furnace shell is designed with a double-layer forced air cooling structure, which keeps the external temperature of the furnace close to room temperature even when working at the highest temperature.
7. Automated Operation: PLC automatic control system simplifies the operation process, improving work efficiency and accuracy.
8. Low Maintenance Design: The vacuum furnace is designed with convenience of maintenance in mind, reducing maintenance costs and time.

Application Case: "Using Vacuum Brazing Furnace for Diamond Grinding Tool Welding Test"
1. Preparation Work:
Check if all components of the equipment are intact and functioning properly.
Read the equipment manual to ensure you understand the operation process.
Wear personal protective equipment, such as safety glasses and gloves.
2. Cleaning and Preparing Parts:
Use acetone to ultrasonically clean the tungsten carbide rod material to remove surface oil and impurities.
Apply a water-based adhesive to the rod material in preparation for laying the brazing material.
3. Loading:
Place the adhesive-coated rod material in the cavity and ensure the brazing material is evenly spread on the rod material.
4. Vacuum Pumping:
Place the quartz tube into the vacuum furnace and pump it to a vacuum of less than 5×10^-4^Pa.
5. Heating Brazing:
Heat to 680℃-740℃ and hold for 15-20 minutes to melt the brazing material and wet the rod material.
6. Cooling:
Under vacuum conditions, remove the rod material from the quartz tube and let it cool naturally to room temperature.
7. Laying Diamond Powder:
Uniformly spread diamond powder on the welded brazing area, with diamond powder specifications typically being 30-50μm.
8. Repeat Brazing Process:
Place the rod material with diamond powder into the cavity again, pump vacuum, and perform the second heating brazing.
9. Post-processing:
After brazing is completed, remove the diamond grinding head and perform necessary post-processing, such as cleaning to remove residues.
10. Quality Inspection:
Inspect the welded diamond grinding head for quality, including the solidity of the welding, the condition of the welding surface, and the welding strength.
The vacuum brazing furnace can provide a high vacuum environment to reduce the possibility of oxidation and precisely control the heating temperature and time to ensure the quality and performance of the diamond grinding head welding. This welding method is suitable for the manufacture of high-end single-layer diamond tools and can significantly improve the grinding efficiency and service life of the tools.
These steps provide a basic guide, and specific operations may need to be adjusted according to the equipment manual and experimental design.
