CNC lathes' requirements for factory environment temperature are usually to operate within a certain temperature range to ensure the normal operation and processing quality of the lathe. While specific requirements may vary based on lathe model, manufacturer, and process requirements, the following are typical ambient temperature requirements for CNC lathes:

1. Conventional temperature range: The conventional temperature range of CNC lathes is usually between 15 degrees Celsius and 35 degrees Celsius. This scope is designed to ensure the operation of the lathe and the proper functioning of the hydraulic, lubrication and cooling systems.
2. Temperature stability: In addition to being within the conventional temperature range, lathes also require the ambient temperature to remain stable. Large temperature changes may cause thermal expansion/contraction of parts and mechanical components, affecting machining accuracy.
3. Dust prevention and filtration: The ambient temperature requirements of lathes are usually also related to dust prevention and filtration requirements. Automakers recommend that workshop air contain no more than 100,000 dust particles per cubic foot, and that lathes should be avoided in areas prone to large amounts of dust.
4. Cooling and lubrication system: The cooling and lubrication system of the lathe is crucial to maintaining normal operation. Ambient temperatures that are too high or too low may affect the performance and stability of the coolant, thereby affecting the machining process. Therefore, overheating or low temperature environments should be avoided when operating the lathe.
5. Special Requirements: Specific lathe types and applications may have additional ambient temperature requirements. For example, for high-speed cutting lathes, temperature control is more critical because high-speed cutting may generate greater heat. In this case, it may be necessary to control the temperature and take appropriate cooling measures.

In general, the environmental temperature requirements of CNC lathes are mainly to maintain a stable and appropriate temperature range to ensure the normal operation and processing accuracy of the lathe. In order to meet these requirements, the workshop should provide good temperature control and ventilation systems, and the lubrication and cooling systems of the lathe should be regularly inspected and maintained. Please note that the specific lathe operating manual and information provided by the manufacturer should be used as an accurate reference for operation and maintenance.
