Why does the wire cutting machine not stop after cutting? [Zhikai CNC professional answer]
There are many possible reasons why the wire cutting machine will not stop after cutting. The following will analyze from the aspects of mechanical, electrical and control systems.
1. Mechanical reasons:
(1) The workpiece is not completely cut off:
When the wire cutting machine is cutting a workpiece, the cutting speed may be too fast or the cutting thickness is too large, resulting in incomplete cutting. In this case, the machine will continue cutting until the workpiece is completely cut.
(2) The workpiece is not firmly fixed
The machining accuracy and cutting quality of the wire cutting machine are related to the degree of fixation of the workpiece. If the workpiece is not fixed well, it may shift or rotate during the machining process, resulting in substandard machining quality or increased wear of the molybdenum wire. Therefore, the clamping of the workpiece needs to be carried out strictly in accordance with the specifications, and check whether the clamping force meets the requirements.
2. Power supply reasons:
(1) The cutting power is not turned off:
During the cutting process, the wire cutting machine needs to be powered by a cutting power supply. If the cutting power supply is not turned off, the machine will continue cutting until the cutting power supply is turned off.
(2) Cutting current is not disconnected:
During the cutting process, the wire cutting machine needs to provide cutting energy through the cutting current. If the cutting current is not disconnected, the machine will continue to cut until the cutting current is disconnected.
3. Control system reasons:
(1) Control system failure:
The control system of the wire cutting machine may have a fault, causing the machine to fail to shut down normally. For example, the sensor of the control system fails and cannot detect the signal that the cutting is completed, thus failing to trigger the shutdown action.
(2) Control program error:
There may be errors in the control program of the wire cutting machine, which may cause the machine to fail to stop normally. For example, the stop command in the control program is not executed correctly, or the stop condition is set unreasonably, which may cause the machine to fail to stop.
In summary, the reason why the wire cutting machine does not stop after cutting may be due to problems in many aspects such as machinery, power supply and control system. In order to ensure that the machine tool can stop normally, it is necessary to perform regular maintenance and overhaul of the machine tool, troubleshoot in time, and reasonably set and debug the control system. In addition, the operator also needs to receive professional training and be familiar with the operation and maintenance knowledge of the machine tool to ensure the safe operation of the machine tool.
