CNC vertical lathe fault inspection methods mainly include the following:

1. Intuitive diagnosis method: CNC vertical lathe This is a preliminary diagnosis of lathe faults using visual inspection, hand touch, power on, etc. for faulty lathes. You can carefully ask the personnel at the fault site about the fault generation process, fault symptoms and fault consequences. This may require multiple inquiries during the entire analysis and judgment process.

2. Instrument measurement and diagnosis method: Use the electrician’s conventional testing instruments to detect the voltage, power supply, pulse signal, etc. of the faulty part, and compare it with the normal value to analyze and determine the fault location. For example, use a multimeter to check the status of each power supply, measure the relevant signal status measurement points set on some circuit boards, use an oscilloscope to observe the amplitude, phase and even presence of relevant pulsation signals, and use a PLC programmer to find the PLC program. Fault location and cause, etc.

3. CNC vertical lathe signal and alarm indication analysis method: Hardware alarm indication refers to various status and fault indicators on various electronic and electrical devices including CNC systems and servo systems. Combining the status of the indicator light and the corresponding function description, you can learn the indication content, cause of the fault, and troubleshooting methods.

4. Self-diagnosis function method: Make reasonable use of the self-diagnosis function of the CNC lathe, and analyze the CNC vertical lathe based on its fault display to obtain the approximate cause of the fault.

5. Knock diagnosis method: Each control system of a CNC lathe is composed of a circuit board. Any false soldering or poor contact on the circuit board may cause malfunctions. CNC vertical lathes can use insulators to gently tap the suspected spots where there is suspected false soldering or poor contact. If the fault worsens, the fault point should be at the tapped location.

In addition, depending on the specific fault situation, it may be necessary to use methods such as the exchange diagnosis method for fault inspection. In general, fault inspection of CNC vertical lathes requires comprehensive consideration of multiple methods and analysis and judgment based on specific conditions. During inspection and maintenance, be sure to pay attention to safety and follow operating procedures to avoid personal injury or equipment damage.
