Before using a CNC vertical lathe, it is very important to conduct a comprehensive inspection to ensure the safety and normal operation of the machine tool. Here are some common inspection items:

1. Machine tool appearance inspection: Check the appearance of the CNC vertical lathe for damage, scratches or other abnormalities.
2. Power supply and electrical system inspection: Check whether the power cord, switch and socket of the CNC vertical lathe are normal to ensure that the electrical system is stable and reliable.
3. Lubrication system inspection: Check whether the lubricating oil in the CNC vertical lathe lubrication system is sufficient, whether the lubricating oil pipeline is unobstructed, whether the lubrication points are clean, and add or replace lubricating oil as needed.
4. Cooling system inspection: Check whether the coolant in the cooling system of the CNC vertical lathe is sufficient, whether the coolant pipeline is unobstructed, whether the pump and filter are working properly, and clean or replace the coolant as needed.
5. Spindle and feed system inspection: According to the guidance of the CNC vertical lathe operating manual, check whether the spindle and feed system are operating normally, including spindle speed adjustment, feed speed adjustment and rapid movement function.
6. Tool and tool system inspection: Check the wear and damage of CNC vertical turning tools, and replace or adjust the tools as needed.
7. Inspection of fixtures and workpiece clamping systems: Check the stability and clamping force of the CNC vertical lathe fixtures and workpiece clamping systems to ensure that they can correctly clamp the workpiece.
8. Control system inspection: Check whether the power supply, display screen, keyboard, manual control device, etc. of the CNC system are working normally, and further check whether the circuit connection and parameter settings of the CNC system are correct.
9. Inspection of protective devices: Check whether the safety doors, protective covers, emergency stop buttons and other protective devices of the CNC vertical lathe are intact and ensure they are working properly.
10. Flatness and accuracy inspection: According to actual needs, use appropriate measuring tools and equipment to check the flatness and accuracy of the machine tool to ensure that it meets the processing requirements.

The above are some common inspection items before using the vertical lathe. Ensure that each inspection is carefully checked and handled, and the operation manual and safety procedures are strictly followed to ensure the safety and stable performance of the machine tool during use.
