4.5 inches grinding disc is one of the important grinding tools. Because it has low heat resistance, good self-sharpness, simple production, short process cycle, and certain elasticity, it is widely used. In the process of use, we must pay attention to some problems. After summing up, we mainly summarize the following 5 points:
1. Before using the grinding disc, be sure to check the product for cracks, products, and dumb sounds. If it is, it cannot be used.
2. The speed of the grinding disc must not exceed the specified safe working line speed.
3. Do not use the end face grinding disc exclusively. Please do not work with the end face of the grinding disc.
4. When 4.5 inches grinding disc is working on the workpiece, please do not push the workpiece with the lever to increase the pressure on the grinding disc.
5. Special dressing tools should be used for dressing the grinding disc. Operators must wear protective goggles when trimming.
