Positioning device when the EDM processing of the precision workpieces such as tool.Operation principle is：It is X to take two points, midpoint at both ends in X-axis
The dead-center position of axis determines the dead-center position that can determine X-Y plane after the zero of Y-axis according still further to this method after being rotated by 90 °.By
It is limited in EDM machining tool strokes, the mold that need to be processed often super machine tool travel, in this case mold have no idea into
Access in effective point of row, it is generally the case that can generally take the base that additional datum hole is processed as subsequent segment on mold
On schedule.But this method has the following problems：Multiple segmental machining makes the mobility of lathe reduce, and repeatedly segmental machining meeting
Mismachining tolerance is set to increase, it is difficult to reach mold and be expected required precision.
In order to solve the above-mentioned technical problem, the utility model proposes a kind of super machine tool travel workpiece is processed for EDM
Edge searching device, the device increase a crossbeam on the basis of original lathe reference sphere, solve the super machine tool travel of workpiece and are not easy to take
Several problems avoids multiple segmental machining, improves lathe mobility and Workpiece Machining Accuracy, reduces plant personnel operation difficulty,
Shorten the process-cycle, reduces production cost.
