Before actually operating a CNC lathe for processing, a series of inspections and preparations must be carried out to ensure the smooth progress of the processing process and the stability of the processing quality. Here are some things you must check:

1. Workpiece preparation: Ensure that the size, shape and material of the CNC lathe workpiece meet the processing requirements, and clean the surface of the workpiece to remove dust, oil and other impurities.

2. Tool preparation: Check whether the selection of CNC lathe tools meets the processing requirements, and whether the tools are seriously worn or damaged and need to be replaced or repaired in time.

3. Fixture preparation: Check whether the clamping device of the CNC lathe fixture is firm and reliable, and whether the clamping force is appropriate to ensure that the workpiece will not move or loosen during processing.

4. CNC program: According to the CNC lathe processing technology requirements, load the correct CNC program, and ensure that the program contains the correct cutting parameters, processing paths and workpiece coordinate system settings.

5. CNC system inspection: Check whether all functions of the CNC lathe CNC system are normal, including CNC panel, operation interface, axis movement, tool switching and other functions.

6. Tool length and radius compensation: Ensure that the tool length and radius compensation settings of the CNC lathe are correct to ensure the accuracy and dimensional accuracy of the machining contour.

7. Tool measurement: CNC lathes measure and calibrate tools, including tool length, tool radius and other parameters, to ensure that the size of the tool is consistent with that set in the CNC program.

8. Safety inspection: Check whether all safety equipment of the machine tool is normal, including emergency stop buttons, protective covers, safety doors, etc., to ensure the safety of operators and equipment.

9. Lubrication system: Check whether the lubrication system of the machine tool is operating normally and whether the lubricating oil is sufficient to ensure the smooth operation of the machine tool during processing and the processing accuracy of the parts.

10. Machine tool surface cleaning: Clean the work surface and guide rails of the CNC lathe to ensure smooth workpiece clamping and axis movement.

11. Processing environment: Check whether the CNC lathe processing environment is suitable for processing requirements, including factors such as temperature, humidity, lighting, etc., to ensure the stability of the processing process and the quality of the workpiece.

12. Other equipment inspection: CNC lathe inspection auxiliary equipment such as coolant supply system, waste removal system, etc. are operating normally to ensure the smooth progress of the processing process.

The inspection and preparation of these matters are important steps to ensure the smooth progress of CNC lathe processing and stable processing quality.
