In the field of super - hard abrasive tool manufacturing, diamond grinding wheels are widely used in various industrial applications, especially in high - strength grinding scenarios such as grey cast iron processing. However, traditional bonding methods like electroplating and resin bonding have limitations in terms of wear resistance and impact resistance. This is where brazing technology steps in, offering a revolutionary solution.
Let's start with the characteristics of active brazing filler metals. Active brazing filler metals play a crucial role in the brazing process. The selection of these metals is based on their ability to react with diamond and the base metal. For example, some active brazing filler metals contain elements like titanium, which can form strong chemical bonds with diamond at high temperatures. The interface bonding mechanism is another key aspect. When the active brazing filler metal is heated, it wets the diamond and the base metal, forming a strong metallurgical bond at the interface. This bond is much stronger than the mechanical bond formed in traditional electroplating or the chemical bond in resin bonding.
Heat treatment also significantly affects the stability of the brazed diamond grinding wheel. High - temperature heat treatment can enhance the stability of the microstructure of the brazed joint. It helps to eliminate internal stresses and improve the overall strength of the joint. Studies have shown that after proper heat treatment, the wear resistance of the brazed diamond grinding wheel can be increased by up to 30% compared to non - heat - treated wheels.
Compared with traditional electroplating and resin bonding methods, brazing technology has obvious advantages. Electroplating has limitations in terms of high - temperature resistance. In high - speed and high - pressure grinding operations, the electroplated layer may peel off due to overheating, reducing the service life of the grinding wheel. Resin - bonded grinding wheels are not suitable for high - strength grinding because the resin may break down under high - temperature and high - pressure conditions. In contrast, brazed diamond grinding wheels can withstand temperatures up to 1000°C and have a service life that is 2 - 3 times longer than traditional wheels in extreme working conditions.
In grey cast iron processing, which requires high - strength grinding, brazing technology shows its unique advantages. By adjusting process parameters such as temperature gradient control and optimizing diamond arrangement density, the brazed diamond grinding wheel can better adapt to extreme working conditions. For example, in a high - strength grey cast iron grinding project, by adjusting the temperature gradient during brazing, the impact resistance of the grinding wheel was improved by 20%, effectively reducing the frequency of wheel chipping.
To further illustrate the effectiveness of brazing technology, let's look at some customer case studies. A manufacturing company was facing frequent chipping and low efficiency problems with their traditional grinding wheels in grey cast iron processing. After switching to brazed diamond grinding wheels, they saw a 40% increase in grinding efficiency and a significant reduction in tool replacement frequency. This not only saved them production costs but also improved the overall quality of their products.
| Question | Answer |
|---|---|
| What is a metal active brazing filler metal? | A metal active brazing filler metal is a type of brazing material that contains active elements (such as titanium) which can react with diamond and the base metal to form a strong chemical bond during the brazing process. |
| How does brazing technology improve the wear resistance of diamond grinding wheels? | Brazing technology forms a strong metallurgical bond at the interface between the diamond and the base metal, which can better withstand the wear caused by grinding forces. Additionally, heat treatment can enhance the microstructure stability of the joint, further improving wear resistance. |
