The process of immersion treatment is crucial for improving the grinding performance of abrasive tools such as grinding wheels. Over time, this technique has evolved, encompassing both traditional and modern approaches. In this article, we will explore the drawbacks of traditional immersion treatment methods and shed light on modern immersion techniques that offer enhanced performance and superior results.

1. Drawbacks of Traditional Immersion Treatment for Sandpapers, Abrasive Belts, and Grinding Wheel:

Traditional immersion treatment for grinding wheels involves using various infusing agents based on sulfur. While this process effectively enhances the grinding performance of abrasive tools, it has certain limitations. In the final stages of treatment, the effectiveness of the grinding wheel is often compromised. This is primarily due to the inability of the components to form a homogeneous molten substance, resulting in the uneven distribution of hard fats on the top and sulfur at the bottom of the grinding wheel.

2. Modern Immersion Treatment Techniques:

Modern immersion treatment techniques have been developed to address the limitations of traditional methods. The process begins by heating a grinding wheel to a temperature of 140-150°C. The heated wheel is then immersed in a molten solution of agents heated to 130-135°C. The wheel is rotated at a pulsating speed, gradually decreasing from 2.8 rotations per second to a complete stop over four minutes. This meticulous process ensures the uniform penetration of all the agent components throughout the grinding wheel.

Upon removal from the molten solution, the wheel is spun to discard the excess impregnating agent. The wheel is then left to air for 1-1.5 hours. Following this standardized procedure eliminates the formation of nodules during dressing on diamond surfaces, prevents clogging during grinding, and minimizes the risk of burn marks on the surface being ground.

Immersion treatment is vital in optimizing the grinding performance of abrasive tools such as louvers, thousand-leaf wheels, and grinding wheels. While traditional methods have inherent drawbacks, modern immersion techniques offer significant improvements. Modern immersion treatments enhance grinding efficiency, prevent surface clogging, and eliminate burn marks by ensuring the uniform distribution of impregnating agents throughout the grinding wheel. The advancements in immersion treatments have revolutionized the industry, providing professionals with reliable and high-performance abrasive tools.

Understanding the importance of immersion treatment and the advantages of modern techniques empowers professionals to make informed decisions when selecting and utilizing grinding tools. By embracing the benefits of immersion treatment, industries can achieve superior grinding results while maintaining a focus on safety, efficiency, and productivity.
