The normal operation of a CNC lathe needs to meet a series of conditions, including machine tools, workpieces, tools, coolant and environment. The following are the conditions required for normal operation of CNC lathes under normal circumstances:

1. Power supply: CNC lathes ensure stable and reliable power supply, and the voltage, frequency, etc. must meet the requirements of the machine tool. The power supply needs to be kept stable to avoid affecting the normal operation of the CNC system and spindle.

2. Machine tool stability: CNC lathes need to be placed on a stable and solid foundation to ensure that the overall structure of the machine tool is stable and to prevent the machining accuracy from being affected by vibration or unstable foundations.

3. Coolant system: During the processing of CNC lathes, CNC lathes usually need to use coolant to cool the tools and workpieces to ensure that the temperature is controlled within an appropriate range during the cutting process to prevent deformation of the workpiece and overheating of the tool.

4. Air quality: Keep the air in the CNC lathe workshop clean to prevent dust, foreign matter, etc. from affecting the normal operation of the CNC system and machine tools. For special environments, dust protection measures may be required.

5. Tools: Use appropriate tools for CNC lathes, and ensure that the quality and wear status of the tools meet the requirements. Correct selection of tool type, edge angle and cutting parameters.

6. Cooling and lubrication system: Ensure that the cooling and lubrication system of CNC lathes works normally, provide sufficient lubrication and cooling to tools and workpieces in a timely manner, and reduce friction and wear.

7. CNC system settings: Correctly set the coordinate system, process parameters, tool compensation and other parameters in the CNC system to ensure that the CNC program runs correctly.

8. Operator skills: CNC lathe operators need to have certain CNC machine tool operating skills and relevant knowledge, be able to operate CNC lathes correctly and safely, and handle abnormal situations in a timely manner.

9. Regular maintenance: CNC lathes perform regular machine tool maintenance, including cleaning, lubrication, tightening, etc., to ensure the normal operation of each component.

10. Safety protection: CNC lathes ensure that safety protection equipment, such as emergency stop buttons, grating sensors, etc., are intact to ensure the safety of operators.

Reasonable satisfaction of these conditions can ensure that CNC lathes achieve high processing accuracy and efficiency during normal operation.
