摘要： Provided is a method for correcting perpendicularity of an electrode rod for a super-drill discharge machine. The method is performed using a block with a truncated cone-shaped detection cavity and includes: finding a first center point of a circle on a first XY plane within the detection cavity; moving a tip of the electrode rod to the first center point; moving the electrode rod by a predetermined length (H) in a longitudinal direction thereof such that the tip of the electrode is disposed on a second XY plane; finding a second center point of a circle on the second XY plane; and calculating an inclination angle of the electrode rod by using a trigonometric function of a triangle in which the hypotenuse thereof is the predetermined length (H) and the adjacent side thereof is a distance from the tip of the electrode rod to the second center point on the second XY plane.

摘要： An electrical discharge machine for improving the guide alignment base structure consisting of a guide alignment base having vertical threaded holes. Furthermore, the guide alignment base has axial adjustment holes that are respectively aligned with the vertical threaded holes, the diameters of the axial adjustment holes slightly larger than the diameters of the vertical threaded holes to enable the insertion of adjustment screws through the axial adjustment holes and fastening into the vertical threaded holes. With a spherical body in between serving as a center, the adjustment screws tilt the guide alignment base forward, backward, leftward, and rightward to adjust the perpendicularity of the guide. Horizontal adjustment screws through the guide alignment base secure the guide alignment base transversely such that the guide alignment base effectively achieves stable positioning to thereby prevent the vertical and horizontal deviation of the guide alignment base when it is impacted.
