To avoid excessive heat generated during the grinding process of an external cylindrical grinder, the following measures can be taken:
1. Control grinding speed and feed rate: Reduce the grinding speed and feed rate appropriately to minimize the heat generated during grinding.
2. Improve cooling conditions: Use appropriate coolant, such as cutting fluid, to cool the grinding area in a timely manner and remove heat.
3. Choose the appropriate grinding wheel: Select the appropriate grinding wheel material and particle size according to the workpiece material and processing requirements, and reduce the grinding temperature.
4. Reduce wheel blockage: Reasonably choose the type and concentration of cutting fluid to reduce wheel blockage and lower grinding temperature.
5. Adjust grinding parameters: Based on the workpiece material and processing requirements, adjust the grinding depth, grinding fluid flow rate, and other parameters of the external cylindrical grinder reasonably to reduce the grinding temperature.
6. Regular maintenance of machine tools: Regularly inspect and maintain the hydraulic system, cooling system, and other components of the machine tool to ensure their normal operation and reduce grinding temperature.
7. Use insulation materials: Use insulation materials in key parts of the machine tool to reduce heat transfer and diffusion, and lower grinding temperature.
By taking the above measures, it is possible to effectively avoid excessive heat generated during the grinding of the cylindrical grinder, and improve the processing quality and efficiency.
