Analysis of the influence of temperature changes on CNC precision parts processing

We all know that the accuracy of CNC machine tools is a very important point and one of its advantages, so it is very important to grasp the accuracy.

Of course, during processing, there are also many factors that can affect the machining accuracy of CNC machine tools. So back to the topic, will the change of temperature affect the CNC machining accuracy? The answer is yes. Temperature is one of the factors that affect the accuracy of CNC machining, which is what we often call thermal deformation.


Our common temperature changes, such as the temperature of the workshop environment, the heating of the motor, and the heat generated by the friction of mechanical motion, may cause the temperature of the CNC machine tool to be unbalanced in various parts of the temperature, thereby affecting the machining accuracy of the CNC machine tool.

To give a very simple example, for example, when we process an ordinary screw rod on an ordinary CNC machine tool, there will be a certain error in the workpiece milled in the morning compared with the workpiece processed in the afternoon. Then it is obvious that a constant temperature environment is helpful to reduce the error.
