Common faults and maintenance points of signal communication system for CNC lathe
In the operation of CNC lathes, signal communication plays an important role in transmitting instructions and returning results. Once a problem occurs, it makes it impossible for the instructions from the control center to reach the execution end, and the feedback from the execution end cannot be returned to the control center, resulting in the entire system crashing. Today, we will explain the common faults and maintenance points of CNC lathe signal communication systems.
Interference issue:
Phenomenon: Unstable size, vibration marks on the surface, and inexplicable alarm.
Reason: The power line and signal line are not wired separately; Poor grounding; The shielding layer is damaged.
Countermeasure: Strictly distinguish between strong/weak current cable trays; Ensure good grounding; Check the cable shielding layer.
Connection issue:
Phenomenon: Communication interruption, driver alarm, feedback value jumping.
Reason: Loose or oxidized connector; The cable broke due to long-term movement.
Countermeasure: Check and tighten all connectors; Regularly inspect the wear and tear of cables in moving parts.
Component damage:
Phenomenon: Encoder alarm, position loss.
Reason: Encoder and grating ruler are contaminated with oil, coolant, or physically damaged.
Countermeasure: Keep the detection components clean; Avoid collisions.
The above are common faults and maintenance points of the CNC lathe signal communication system. We hope that the above explanation can be helpful for everyone when using the CNC lathe signal communication system in the future.
