Before using CNC vertical lathe, it is very important to carry out the following preparations:

1. Check the status of the machine tool: Check the overall status of the CNC vertical lathe, including the appearance of the machine tool, bed, guide rails, spindle, tool magazine and other components. Make sure there is no obvious damage or abnormality to the machine tool.
2. Clean the machine tool: Clean the machine tool, including removing dust and chips on the bed and guide rails, cleaning the spindle area and tool magazine. Keeping machine tools clean will help improve work efficiency and processing quality.
3. Calibrate tools: Check and calibrate the required tools. Ensure that the quality and dimensions of the tool are as required and that the tool is properly clamped as recommended by the machine tool manufacturer.
4. Prepare fixtures or fixtures: According to the shape and size of the workpiece to be processed, prepare appropriate fixtures or fixtures to fix the workpiece. The choice of fixture should consider the stability and processing needs of the workpiece.
5. Check tool inventory: Make sure there is enough tool inventory to prepare for different types of processing needs. Check the blades in your tool inventory for wear and replace or repair them if necessary.
6. Calibrate measuring tools: Prepare and calibrate the required measuring tools, such as calipers, micrometers, dial indicators, etc. Ensure the accuracy of measurement tools for verification and adjustment of machining quality.
7. Check the hydraulic and cooling systems: Make sure the hydraulic and cooling systems are working properly. Check whether the supply of hydraulic oil and coolant is sufficient and make sure there are no leaks or blockages in the system.
8. Start the CNC system: Start the CNC system correctly and ensure that the control panel and interface are connected properly. Load and verify required machining programs and parameters to ensure the accuracy and reliability of the CNC system.
9. Safety protection measures: Ensure that the safety protection measures around the machine tool are intact, such as safety doors, manhole covers, warning signs, etc. Confirm that operators have adequate personal protective equipment and are familiar with the safe operating procedures of the machine tool.

The purpose of these preparations is to ensure that the CNC vertical lathe can work normally during use and provide efficient, precise and safe processing capabilities. After the preparation work is completed, the operator should provide necessary training and guidance on the operation and safety requirements of the machine tool to ensure correct operation and processing quality.
