[Prior Art] As shown in the seventh figure, the conventional linear electrical discharge machine system includes: a main body 80 having an upper fixing portion 81 and a lower fixing portion 82 ′ surrounding the upper and lower fixing portions 81 and 82 Working space 83; a plurality of processing electrode groups 90 are arranged in the working space 83, and are vertically fixed between the upper and lower fixing portions 81 and 82, and a plurality of processing electrode groups 90 includes: The group of rollers 91 is provided between the upper and lower fixing portions 81 and 82 corresponding to a plurality of processing electrode groups 90, and the plurality of wire electrodes 92 is corresponding to and is held between the plurality of rollers 91, which is a custom. structure. The shortcomings of conventional use are as follows: [1] It is not possible to perform the cutting process of individually adjusting the angle. The conventional wire electrode system is fixed between the rollers, and the roller system is fixed between the upper and lower fixed parts. There is no design that can be adjusted. Therefore, the conventional wire electrode can only be used to cut the workpiece in a single vertical state. , Can't do different angle or change cutting process. [2] The processing accuracy is low. The conventional wire electrode system is fixed between the rollers ’so because of the rotation of the roller, the inertial vibration of the workpiece during the cutting process, the wear of the roller, or even the vibration of the motor, etc.

The wire electrode 23 has two ends, and is fixed to the upper and lower wire holders 21 and 1 with one end and the other end. 22, and a space 30 is surrounded by the adjacent line electrodes 23, which is characterized in that both ends of the adjacent line electrodes 23 are displaced steplessly in the same direction, thereby changing the shape of the space ; By changing the spacing portion 30 in this way, the function of performing wire cutting processing on the workpiece 60 can be achieved by a plurality of wire electrodes 23 that can individually adjust the cutting angle. Refer also to the second figure, “One end of the wire electrode 23” is moved on the upper chute ill by the upper wire holder 21, and the upper fixing portion η is provided with a movable group 40 above it. The movable group 40 indirectly drives the wire electrode 23 to perform a different axial and longer-distance displacement, that is, to cause a large range of pattern changes at the interval portion 30. The activity group 40 includes a linking block 41 (this is conventional, so the drawing is not shown here, and is shown in the figure), which is set on a fixed frame 42. The linking block 4 is driven by a first power source 43. It can slide inside the fixed frame 42, and the hydrating block 41 has an upper edge surface, and the upper edge surface is pivotally connected to the lower production surface of a movable block, and the movable block 44 is subjected to a second power source 46 is driven, and slides inside a body 45; and the movable block 44 is fixed with an inverted L-shaped coupling arm 47, which indirectly drives the upper fixing part 11 to be displaced.
