The CNC lathe has the following requirements and influences on the ambient temperature of the workshop during the processing process:

1. Temperature stability: CNC lathes usually need to be operated and processed in a relatively stable temperature environment. Excessive temperature fluctuations will cause the metal material of the machine tool to expand or contract, affecting the accuracy and stability of the machine tool. Therefore, in order to maintain the stability and precision of processing, the ambient temperature of the workshop should be as stable as possible.
2. Avoid excessive temperature: Excessive ambient temperature will have adverse effects on CNC lathes. High temperature may cause failure of CNC system, electronic components and servo system, and even damage key components. At the same time, the heat generated during the processing will be more difficult to dissipate, increasing the temperature rise of the machine tool and affecting the processing quality and accuracy. Therefore, measures should be taken to reduce the temperature or enhance heat dissipation in a hot environment.
3. Avoid too low temperature: Too low ambient temperature may cause the cooling and lubrication system of the machine tool to fail to work normally, thus affecting the lubrication and cooling effect of the machine tool. Some lubricants and liquid coolants can become viscous or solidify in low temperature environments, further affecting the normal operation of machine tools. In addition, too low temperature may also cause thermal expansion and contraction of machine tool components, affecting machining accuracy.
4. Control humidity: In addition to temperature, ambient humidity also has a certain impact on the operation and accuracy of CNC lathes. High humidity environment will lead to corrosion of metal parts of the machine tool and abnormality of the mechanical transmission system, reducing the life and precision of the machine tool. At the same time, high humidity may also cause water vapor condensation on the surface of the machine tool and the surface of the workpiece, affecting the processing quality. Therefore, the ambient humidity of the workshop also needs to be controlled within an appropriate range.

To sum up, CNC lathes have strict requirements on the ambient temperature of the factory building, requiring stable temperature, avoiding excessively high or low temperature, and controlling appropriate humidity. The workshop should carry out temperature and humidity control according to the working requirements of the CNC lathe and the manufacturer's recommendations to ensure the normal operation and machining accuracy of the CNC lathe.
