By high-speed electric main shaft 51 and 5 integral installation of electro spindle fixture on sliding block 52, and guarantee electro spindle fixture 5, sliding block 52 with
And the depth of parallelism between guide rail platform 4.
The then relative altitude of adjustment electro spindle fixture 5, is fixedly mounted on electrolytic cell 2 on support 21 by screw, and
According to actual processing needs, select 513 clamping of tool-electrode of suitable diameter size in the lower section where electro spindle collet 512,
Then workpiece 201 to be added and prefabricated mould 202 are mounted in the body structure of electrolytic cell 2, and make workpiece to be added 201 and pre-
Face where 202 middle part of molding jig fits closely, while guaranteeing that semi-circular pilot hole 2021 and semicircle orifice 2011 are formed by circle
Axially bored line, the axis collinear with tool-electrode 513.Where the upper surface with movable plate 231 semi-circular at this time and semicircle orifice 2011
Upper surface is concordant, to guarantee the lower end surface of tool-electrode 231 and semi-circular with existing for 2011 upper surface of movable plate 231 and semicircle orifice
It is consistent to process gap, to ensure the machining accuracy of semicircle orifice.
Meanwhile installation can be made with tool-electrode 513 in the inside of high temperature resistant, the prefabricated mould 202 of transparent metal glass
The semi-circular of synchro-feed remains with movable plate 231, the semi-circular upper surface with movable plate 231 and the lower end surface of tool-electrode 513
Distance identical with processing gap, the outer surface of tool-electrode 513 and high temperature resistant, transparent 202 inside of prefabricated mould are prefabricated
Semi-circular pilot hole 2021 constitutes side and processes gap, while the lower end surface of tool-electrode 513 and semi- cylindrical are with movable plate 231
Upper surface constitutes end face and processes gap.The miniature lead screw 23 that second servo motor 24 is driven drives semi-circular with the work of movable plate 231
Axial feed, and make synchronous speed feeding altogether in the same direction between miniature lead screw 23 and high-speed electric main shaft 51, thus in the mistake of electro-discharge machining
It is always ensured that machined semicircle orifice 2011 in journey and the semi-circular section with movable plate 231 is a complete borehole structure.
Working solution is injected when processing in electrolytic cell 3, and make working solution be totally submerged the upper surface 1 of workpiece 201 to be added~
Then 2cm adjusts the visual angle of high-speed camera 6, so that it is in the optimum position for processing situation inside observation electrolytic cell 2, use
The processing situation in gap and end face processing gap is processed in the side for observing workpiece 201 to be added in real time；Connect processing experiment dress
The pulse power set adjusts the initial manufacture gap between tool-electrode 513 and workpiece to be added 201, passes through data line
Industrial personal computer 3 and high-speed camera 6 being connected, observed and recorded in processing gap in real time with will pass through high-speed camera 6
Bubble generation, gas film behavior and electric discharge phenomena；Finally, tool-electrode 513 will process one in the edge of workpiece 201 to be added
A semicircle orifice 2011.
As shown in figure 9, the specific flow chart of speed feeding altogether is synchronized in the same direction for the embodiment of the present invention, actual processed
Cheng Zhong will realize between miniature lead screw 23 and high-speed electric main shaft 52 the synchronous speed feed altogether in the same direction of seat, need the movement control to the two
End processed carries out feedback regulation, and high-speed electric main shaft 52 first feeds down speed by motion controller control tool-electrode 513,
And it according to actual processing can need that feed speed is adjusted.Miniature lead screw 23 is driven by the second servo motor 24 simultaneously,
Second servo motor 24 is driven by host computer, and the transmission ratio of miniature lead screw 23 and the second servo motor 24 is definite value, passes through control
The rotation of the second servo motor 24 is made to adjust the feed speed of miniature lead screw 23.And the feed speed of the two is compared, if occurring
Different steppings carry out feedback regulation immediately, and ensure that the two synchronizes total speed feeding.It is final to guarantee miniature lead screw in process
23 make synchronous total speed in the same direction with high-speed electric main shaft 51 between the two feeds.
