The following measures can be taken to effectively prevent thermal errors generated during the machining process of the circular machine:
1. * * Thermal balance control * *:
-Implement thermal balance control on the circular machine, by predicting and controlling the distribution of heat sources, to maintain the stability of equipment temperature distribution as much as possible.
-Install temperature sensors to monitor the temperature of key areas in real-time and adjust the working status of the cooling system based on temperature changes.
2. * * Cooling liquid circulation * *:
-Using coolant in the cutting area not only reduces cutting temperature, but also washes away chips and reduces friction.
-Optimize the coolant circulation system to ensure that the coolant is evenly and effectively distributed in the cutting area.
3. * * Material selection * *:
-Choose materials with lower thermal expansion coefficients to make key components, such as the bed, spindle, etc., to reduce size changes caused by temperature changes.
4. * * Reduce unnecessary friction * *:
-Use appropriate lubricants to reduce friction between sliding surfaces and contact points, thereby reducing the heat generated by friction.
-Optimize the mechanical structure and reduce unnecessary friction points, such as reducing unnecessary fit gaps and improving the smoothness of the contact surface.
5. * * Processing process control * *:
-Control the machining speed, feed rate, and cutting depth to avoid excessive cutting causing excessive heating of the machine tool.
-Timely arrange cooling and pause times during the machining process to allow time for the machine tool and workpiece to reach thermal equilibrium.
6. * * Preheating treatment * *:
-Before starting high-precision machining, preheat the machine tool to reach a stable working temperature and reduce thermal errors caused by temperature fluctuations.
7. * * Optimize control system * *:
-By optimizing the CNC system, real-time monitoring and control of cutting force and cutting temperature can be achieved, and cutting parameters can be adjusted in a timely manner to avoid overheating.
8. Regular inspection and maintenance:
-Regularly check the operation status of the cooling system and temperature monitoring system to ensure their normal operation.
-Regularly clean and maintain the machine tool to remove dust and dirt, and improve heat dissipation efficiency.
Through the above measures, the thermal errors generated during the machining process of the circular machine can be significantly reduced, and the machining accuracy and stability can be improved. At the same time, these measures also help to extend the service life of equipment and reduce production costs.
