Wire tightening device of wire cutting, as the name implies, is a device for tightening molybdenum wire.
What is wire tightening device for WEDM
During WEDM, due to the reciprocating wire structure, the molybdenum wire will become loose due to the tension after being used for a period of time. This will have a certain impact on the surface finish of the workpiece. In this case, the function of the wire tightening device is reflected. It can make the molybdenum wire in a relatively stable state, because the wire tightening device will maintain the same force of tension in the process of reciprocating operation, so that the processed workpiece will have a significant improvement in the smoothness.

The installation of a screw tightener is also helpful to the problem of single side loosening. Generally, the screw tightener is installed between the wire conveying barrel and the rear guide wheel. In this way, even if the machine tool has the phenomenon of unilateral loosening, the screw tightener can also play a certain role.
What is the function of wire tightening device in WEDM
Generally, there are spring tightening, counterweight tightening and motor tightening. On the market the common is the spring take-up. The advantages of spring tension device are low cost and convenient installation. The disadvantage is that the spring has a certain service life, so the effect of the wire tightening device will be changed due to the change of the spring. The advantages of counterweight wire tightening and motor tightening are long service life and adjustable tightening force. Of course, the cost is relatively high. The selection of the wire tightening device depends on the requirements of the workpiece, and it is not necessarily said that it will be good if it is equipped with a wire tightening device. After all, the molybdenum wire has been pulled all the time during the processing, which will have a little influence on the molybdenum wire.
