To understand the installation method and positioning of the middle wire guide, it is necessary to overlap the center of the wire guide hole and the center of the electrode wire. The specific operation process is as follows:
1、 The guide wire nozzle has certain directionality, so it is necessary to put the larger side of the central cone upward, press the gland in place, and then loosen the ring until it reaches a quarter turn, so that it is in a free state without compression. These are the points that should be paid attention to when putting the wire guide nozzle into the guide.
2、 After the electrode wire is put in, you can also try to thread the electrode wire into the wire guide nozzle, and then put the wire guide nozzle into the seat.
3、 After starting the machine tool, the electrode wire will start to run rapidly. Since the guide wire nozzle is in free state, the wire guide nozzle will be automatically aligned concentric when the electrode wire moves.
4、 The first calibration will make the electrode wire perpendicular to the worktable, and the second calibration will be carried out based on this.
5、 Tighten one of the guide gland slowly. Due to the compression, the wire guide nozzle will have a very slight deviation. In this case, it is necessary to conduct a second correction, but it is impossible to adjust the u.v axis again. At this time, it is necessary to move the water spray plate of the guide to adjust the electrode wire to the vertical state. After the above operation, the electrode wire and the guide device can be basically repeated, and the pursuit of overlap is to reduce the wear of the guide wire nozzle.
