Not Every Machine Noise Means a Problem

When a machine is running, different sounds do not always mean that something is broken. In particular, when you are checking the machine and press the black Jog Button, the motor may produce a brief current hum or movement sound. This is because the jog function makes the motor move intermittently, so the sound is different from normal continuous operation. If you hear a motor sound when pressing the black jog button, but no unusual noise when pressing the green start button for normal running, there is usually no need to worry.

2. Check Whether the Noise Only Happens in Jog Mode

Understanding the two buttons helps you judge the sound correctly:

Key point: If the black jog button produces a brief current sound but the green start button runs normally without unusual noise, the motor is usually not faulty.

3. Check the Lubrication System

If the noise clearly becomes louder during normal continuous running, start the inspection with lubrication. Check the following items:

• Whether the automatic oiling function works normally.
• Whether the lubricating oil is sufficient.
• Whether the upper and lower gears need additional oil.
• Whether other moving parts are properly lubricated.

Insufficient lubrication increases friction between parts and makes the running sound louder. Regular lubrication is one of the simplest ways to keep the machine running smoothly.

4. Check Whether the Slide Plate Screws Are Too Tight

This is a valuable and often overlooked fault point. Check the following:

• Check whether the slide plate screws are tightened too much.
• Over-tightened screws can increase the running resistance of the slide plate.
• When the slide plate does not move smoothly, it may produce friction or abnormal noise.
• After adjustment, observe the machine's running condition again.

Key point: The slide plate should move smoothly without excessive resistance. Always check according to the machine's adjustment requirements rather than making large random changes.

5. Check for Wear and Loose Components

If abnormal noise continues during normal production, check the following. The goal is to observe first, identify the source of the sound, and then act:

• Whether the wire guide parts are worn.
• Whether the forming parts are abnormal.
• The working condition of the gears.
• Whether screws and bolts are loose.
• Whether there is obvious friction or collision between parts.

6. Listen to the Type of Noise

Classifying the sound makes troubleshooting much easier. The table below suggests what to check for each type of noise:

7. When Should You Contact JINLIDA?

Contact the JINLIDA after-sales team in good time if you cannot identify the source of the sound, if abnormal noise continues during normal running, if the noise keeps getting louder, if it remains after adjustment and lubrication, or if it is accompanied by vibration or abnormal machine operation. Please do not disassemble the machine blindly or adjust key components on your own. JINLIDA can help identify the problem based on the video, the location of the noise, the machine's running condition and the operating method that produced the noise.

8. Conclusion

Before assuming that a CNC gabion mesh machine has a fault, first determine when the noise occurs. If it is only a brief motor sound from the black jog button, while the green start button runs normally without unusual noise, there is usually no need to worry. What truly deserves attention is persistent, gradually worsening, or vibration-related abnormal noise during normal continuous production.
