Can wire cutting realize automatic threading when cutting different holes?

When wire cutting is used for machining, it is necessary to drill holes in different positions in advance for automatic threading. Therefore, wire cutting generally does not automatically thread when cutting different holes. Some high-end WEDM machines are equipped with automatic threading devices, which can automatically thread during machining, greatly improving the machining efficiency and accuracy.

Automatic threading device usually consists of a special set of needles and detectors. Its working principle is that before machining, the machining point is detected with a special needle to obtain coordinate information, and then the coordinate data is input into the control system of the machining machine tool. During the machining process, when the wire is cut through the hole, the detector will automatically detect the conductive path. When the detector detects the fixed conductive path, the automatic threading device will start and switch to the automatic threading mode to ensure that the wire cutting can pass through the hole smoothly.

Using automatic threading device can avoid manual threading by operators, improve processing efficiency and accuracy, and reduce the labor intensity of operators and the possibility of human error.
