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： A spark erosion tool includes an electrode arranged on a tool longitudinal axis and an electrode holder aligned along and arranged on the axis and connected to the electrode. The electrode holder includes a moving device for moving the electrode relative to the electrode holder and includes a press for applying pressure transversely to the axis in the area of an imaginary hose extending in the axis. The electrode holder has a cross section corresponding essentially to the electrode. An electrode for a spark erosion tool with a cylinder surface or a spherical surface includes a groove connected to a bore. A deflecting bore can be produced in a drill string part using the spark erosion tool. The deflecting bore is curved and connects two straight flushing bores.

摘要： A fixture for an electro-chemical machining (ECM) electrode is provided. The fixture may include a clamp having a shape and size configured to selectively engage in at least a portion of a selected dovetail slot of a plurality of dovetail slots in a turbine wheel. An electrode mount positions an electrode head relative to the clamp such that the electrode head operatively engages a portion of the selected dovetail slot for electro-chemical machining of the portion. The fixture's electrode may act as a cathode for the ECM process. The fixture allows for ECM on site without removing a turbine wheel from a turbomachine.

摘要： A wire electrical discharge machine for detecting an end face of an object, configured so that when a contact detection movement is started and if contact between the wire electrode and the workpiece is detected, positions in which the contact between the wire electrode and the workpiece is detected are stored as contact detection positions and that when a non-contact detection movement is then started and if non-contact between the wire electrode and the workpiece is detected, positions in which the non-contact between the wire electrode and the workpiece is detected are stored as non-contact detection positions. When it is determined whether or not a set number of times of execution is reached and if the set number of times of execution is reached, a reference position is obtained by adding the radius of the wire electrode and a clearance of the wire guide to an end face determination position.

摘要： A wire electric discharge machine has a function of performing correction of corner shapes independently on an upper surface and a lower surface of workpiece. On the basis of the positions of upper and lower wire guides and the position and the thickness of the workpiece, the wire electric discharge machine calculates, on the upper and lower surfaces of the workpiece, a shape correction amount in a state in which there is a space between the upper nozzle and the upper surface of the workpiece and also in which there is a space between the lower nozzle and the lower surface of the workpiece, from a correction amount at the time when nozzles of the upper and lower wire guides are closely attached to the upper and lower surfaces of the workpiece. The wire electric discharge machine performs shape correction according to the calculated shape correction amount.
