As a high-tech product, the glass laser sandblasting machine is inevitably subject to faults during operation. However, how to troubleshoot these faults has always been a tricky problem. This is because many customers only know how to operate the machine after purchasing it, but have little knowledge about its structure and performance.
Therefore, they often feel at a loss when encountering even minor problems and do not know how to handle them. For this reason, mastering some methods for analyzing and solving equipment faults is extremely necessary. Here, we mainly introduce the solutions to several common faults of the glass laser sandblasting machine.
Fault 1: Alarm Fault of Glass Laser Sandblasting Machine
Over-travel alarm indicates that the engraving machine has exceeded its limit position during operation. Check according to the following steps:
1.Check if the size of the designed pattern exceeds the processing range.
2.Check if the connecting line between the motor shaft and the ball screw of the engraving machine is loose; if so, tighten the screws.
3.Check if the glass laser sandblasting machine and the computer are properly grounded.
4.Check if the current coordinate value exceeds the numerical range of the soft limit switch.
Fault 2: Over-travel Alarm and Troubleshooting of Glass Laser Sandblasting Machine
1.All motion axes will be automatically set to the stop and light-off state. Keep pressing the manual direction key; the machine will resume the linked motion state as soon as it moves away from the limit position (i.e., disengages from the over-travel limit switch).
2.Pay attention to the moving direction when operating the workbench, and make sure to keep it away from the limit position.
Fault 3: Non-alarm Faults of Glass Laser Sandblasting Machine
1.Insufficient repeated machining accuracy: Check according to Item 2 of Fault 1.
2.If the computer is running but the machine does not move: Check if the connector between the computer control card and the electrical box is loose. If yes, insert it firmly and tighten the fixing screws.
3.If the machine fails to detect the signal when returning to the mechanical origin: Check according to Fault 2. The proximity switch at the mechanical origin may be malfunctioning.
