During the test run of the CNC vertical lathe, you may encounter some common faults or problems. The following are several possible test run failures:

1. Electrical connection failure: During the test run, there may be electrical connection failures such as wrong power connection, poor cable contact or short circuit, which will cause the machine tool to fail to power on or operate normally. This requires checking the electrical connections and reconnecting or repairing the fault.
2. Machine tool configuration error: If the machine tool configuration parameters are set incorrectly, it may cause the function to not function normally or operate abnormally during test run. Check the machine configuration parameters to make sure they are set correctly.
3. Sensor failure: The sensor on the CNC vertical lathe may malfunction, resulting in the inability to correctly detect the workpiece position or process conditions. The sensor should be checked for damage or functioning properly and replaced or repaired if necessary.
4. Abnormal movement of the machine tool: During test run, the movement axis of the machine tool may have abnormalities, such as excessive vibration, inability to move smoothly or movement deviation, etc. This may be caused by a shaft drive system failure, servo system issues, or incorrect parameter settings and requires diagnosis and repair.
5. Collision between tool and workpiece: During test run, collision between tool and workpiece may occur, which may be caused by problems such as programming errors, improper fixture installation, or workpiece size out of range. Programming procedures, fixtures, and workpiece dimensions need to be carefully checked to ensure that the tool does not interfere with the workpiece path.
6. Control system errors: During the test run, errors may occur in the control system, such as interface freezing, instruction execution failure or abnormal display, etc. Check the operation and programming of the CNC system and restart or recalibrate the control system.
7. Lubrication system failure: The lubrication system of the CNC vertical lathe may fail, such as abnormal supply of lubricating oil, blockage of lubrication points, etc., which will affect the lubrication and protection of the machine tool. It is necessary to check the working status of the lubrication system and clean or repair the fault.

The above only lists some possible test run faults. The actual situation may vary depending on the machine tool model, brand and configuration. During the test run, timely record the fault symptoms and contact the supplier or technical support team for help and solutions to ensure the normal operation of the machine tool.
