Analysis of High - Quality Brazing Process: The Key Technology to Improve the Durability of Diamond Grinding Wheels

In the field of industrial grinding, the durability of diamond grinding wheels is a crucial factor affecting production efficiency and cost. This article delves into the advanced brazing process, revealing the secrets behind the high - wear resistance of brazed diamond grinding wheels.

Metal Interlayer Material Selection and Interface Bonding Mechanism

The choice of metal interlayer material is fundamental to the performance of brazed diamond grinding wheels. Commonly used materials include silver - copper alloys and nickel - based alloys. Silver - copper alloys offer excellent wettability and relatively low melting points, which can form a good bond with diamond particles at a moderate temperature. Nickel - based alloys, on the other hand, provide high - strength bonding and good corrosion resistance.

The interface bonding mechanism between the metal interlayer and diamond particles is a complex physical and chemical process. Through scientific research and practical verification, it has been found that a well - selected metal interlayer can significantly improve the bonding strength between the diamond and the substrate. For example, in some production cases, using a silver - copper alloy as the interlayer can increase the bonding strength of diamond particles by about 30%, thus enhancing the overall durability of the grinding wheel.

Control of Heating Rate and Optimization of Cooling System

Controlling the heating rate is essential to avoid thermal stress cracks in the diamond grinding wheel. During the brazing process, if the heating rate is too fast, large thermal stress will be generated inside the grinding wheel, leading to cracks and reducing the service life of the grinding wheel. Generally, a heating rate of 5 - 10°C per minute is recommended to ensure a uniform temperature distribution in the grinding wheel.

The cooling system also plays a vital role. Improper cooling can cause grain boundary embrittlement, which reduces the impact resistance of the grinding wheel. By optimizing the cooling rate, such as using a slow - cooling process after brazing, the formation of brittle phases can be effectively prevented. For instance, in a specific production scenario, after optimizing the cooling system, the impact resistance of the grinding wheel increased by 25%, and the overall service life was extended by about 40%.

Real - World Case Studies

To better illustrate the importance of high - quality brazing processes, let's look at some real - world case studies. In a factory, they initially used a traditional brazing process, resulting in a high failure rate of diamond grinding wheels. The average service life of the grinding wheels was only 50 hours, and the unit cost of grinding was relatively high. After adopting the optimized brazing process, including proper metal interlayer selection, heating rate control, and cooling system optimization, the service life of the grinding wheels was extended to 70 hours, a 40% increase. At the same time, the unit cost of grinding was reduced by 20%.

Maintenance Points in Daily Use

In addition to the manufacturing process, daily maintenance also has a significant impact on the service life of diamond grinding wheels. The dressing frequency should be determined according to the actual grinding situation. Generally, dressing once every 10 - 15 hours of use can keep the grinding wheel in good condition. Cleaning the grinding wheel regularly with a suitable cleaning agent can prevent the accumulation of debris and improve grinding efficiency. Moreover, controlling the temperature and humidity environment during storage and use is also necessary. A temperature range of 20 - 30°C and a humidity of 40 - 60% are recommended.

In conclusion, from manufacturing to operation and maintenance, a high - quality brazing process combined with proper maintenance can form a complete life - cycle management system for diamond grinding wheels.
