[0029] When in use, operate the control panel 101 to make the control panel 101 control the blower 3014 to work. Under the action of the blower 3014, the waste chips generated during the cutting of precision parts are sucked into the dust suction pipe 3011 through the dust suction hood 302. At this time, the waste chips are intercepted on the surface of the filter 3012. Since the structure of the filter 3012 is a conical structure, the waste chips can be conveniently dropped along the filter 3012 into the collection tank 3013. The waste chips can be discharged by opening the valve on the surface of the discharge pipe at the bottom of the collection tank 3013. At the same time, the gas is discharged through one end of the blower 3014 to realize the waste chip collection function of the wire cutting machining center.

[0030] Furthermore, if Figure 3 As shown, a tension adjustment mechanism 4 is arranged between the guide wheels 104, and the tension adjustment mechanism 4 consists of a tension adjustment component 401 and a wire wheel 402. A tension adjustment component 401 is arranged on one side of the electrode wire 102, and the surface of the tension adjustment component 401 is installed with a wire wheel 402, and the wire wheel 402 is located on both sides of the electrode wire 102 and contacts with the surface of the electrode wire 102.

[0031] During use, the electrode wire 102 is prone to loosening after a period of time due to electrical corrosion and the continuous movement of the electrode wire 102. At this time, the adjusting screw 4012 can be rotated to make the adjusting screw 4012 push the wheel frame 4013, and the wheel frame 4013 is guided under the action of the guide rod 4011, so that the wheel frame 4013 drives the wire wheel 402 to move outward, pulling the electrode wire 102, so that the electrode wire 102 is in a tensioned state again, so as to realize the tightness adjustment function of the wire cutting machining center.

[0032] Working principle: When in use, first loosen the fastening bolt 2024, then slide the reading slider 2023, so that the reading slider 2023 moves along the slide 2021 to the corresponding scale line 2022, and accurately determine the distance between the electrode wire 102 and the limit baffle 201, then tighten the fastening bolt 2024, fix the reading slider 2023, and then place the precision parts to be cut on one side of the electrode wire 102, so that the surface of the precision parts is in close contact with the surface of the limit baffle 201, and then move the precision parts along the limit baffle 201 to move the precision parts to the side of the electrode wire 102.

At this time, the waste chips are intercepted on the surface of the filter 3012. Since the structure of the filter 3012 is a conical structure, the waste chips can fall along the filter 3012 to the inside of the collection tank 3013, and the waste chips can be discharged by opening the valve on the surface of the discharge pipe at the bottom of the collection tank 3013. At the same time, the gas is discharged through one end of the blower 3014 to realize the waste chip collection function of the wire cutting machining center, thereby avoiding the phenomenon that waste chips fly and are difficult to clean when the wire cutting machining center is in use.

[0034] After a period of time, due to the influence of electrical corrosion and the continuous movement of the electrode wire 102, the electrode wire 102 is prone to loose wire phenomenon. At this time, the adjusting screw 4012 can be rotated to make the adjusting screw 4012 push the wheel frame 4013, and the wheel frame 4013 is guided under the action of the guide rod 4011, so that the wheel frame 4013 drives the wire wheel 402 to move outward, pulling the electrode wire 102, so that the electrode wire 102 is in a tensioned state again, so as to realize the tightness adjustment function of the wire cutting machining center, thereby avoiding the phenomenon of loose wire of the electrode wire 102 when the wire cutting machining center is used, and finally completing the use of the wire cutting machining center.
