In the grinding process, how to choose the peerless suitable grinding wheel grit size to achieve the required roughness?

The performance of rubber wide-angle belts is directly related to the operating efficiency and stability of the entire system in the field of precision machinery and transmission systems. Among them, surface roughness is a key factor affecting the grip between the belt body and the pulley, and its processing technology is particularly important. Grinding wheel grinding, as a traditional and effective means to improve the surface roughness of rubber wide-angle belts, is experiencing the challenges of technological innovation and refined operation. This article will explore in depth how to scientifically and accurately select the peerless suitable grinding wheel grit during grinding to achieve the expected roughness standard, thereby improving the comprehensive performance of rubber wide-angle belts.

The mystery of grinding wheel grit and roughness
Grinding wheel grit, as an indicator of the coarseness of the abrasive on the grinding wheel, directly determines the amount of material that can be removed during grinding and the resulting surface micromorphology. Coarser grinding wheel grit can quickly remove a large amount of material in a short time, but often leads to a larger surface roughness, which is not conducive to precision transmission; while finer grinding wheel grit can provide a more delicate processing surface, but the processing efficiency is relatively low. Therefore, choosing the right grinding wheel grit has become the key to balancing processing efficiency and surface quality.

Path to scientific selection of grinding wheel grit
1. Clarify requirements and set goals
Before grinding with a grinding wheel, it is initial necessary to clarify the surface roughness range required for the rubber wide-angle belt. This standard is usually determined based on the specific requirements of the transmission system, the working environment, and material properties. Setting clear goals will help to select the appropriate grinding wheel grit and grinding parameters later.

2. Material property analysis
Rubber wide-angle belts of different materials react differently to the grinding wheel grit. Rubber materials with high hardness and good wear resistance may require finer grinding wheel grit to ensure surface quality; while relatively soft materials may be suitable for coarser grit to improve processing efficiency. Therefore, in-depth analysis of the physical and mechanical properties of the material is an important prerequisite for selecting the grinding wheel grit.

3. Grain size test and verification
In order to find the peerless suitable grinding wheel grit, small-scale test verification is an essential step. By selecting grinding wheels of different grits to grind the samples and using precision instruments such as surface roughness measuring instruments to quantify the results, the surface roughness changes under different grits can be intuitively compared. This process not only helps to determine the right particle size, but also provides reliable data support for subsequent mass production.

4. Grinding process optimization
The selection of grinding wheel particle size is not isolated from the grinding process. In actual operation, it is also necessary to consider factors such as the rotation speed of the grinding wheel, the feed speed, and the use of coolant. By adjusting these parameters, the grinding effect can be further optimized to ensure that while achieving the required roughness, high processing efficiency and good surface quality are maintained.

Outlook of grinding wheel grinding technology
With the continuous development of intelligent manufacturing and automation technology, the grinding wheel grinding process is moving towards a more intelligent and refined direction. In the future, by introducing advanced sensor technology, big data analysis and artificial intelligence technology, real-time monitoring and optimization of grinding wheel particle size selection and grinding parameters can be achieved, further improving the surface treatment quality and production efficiency of rubber wide-angle belts. Green environmental protection will also become an important trend in the development of grinding wheel grinding technology. By developing new environmentally friendly grinding wheel materials, optimizing coolant formulas, and strengthening waste liquid treatment, the impact on the environment during grinding can be reduced, and the production of rubber wide-angle belts can be promoted to a more green and sustainable direction.
