摘要： An electric discharge machining module for forming a hole in a workpiece with an electrode is provided, comprising a module body, a spindle assembly and a piston assembly. The module body defines a throughbore extending along an axis. The spindle assembly is at least partially positioned within the throughbore for rotation around the axis and includes a first electrode passageway which is coaxial with the axis for receiving the electrode therethrough. The piston assembly is positioned within the throughbore for movement along the axis between a released position and an engaged position. The piston assembly includes a second electrode passageway which is coaxial with the axis for receiving the electrode therethrough. A collet closer of the piston assembly engages a collet of the spindle assembly when the piston assembly is in the engaged position such that the collet grips the electrode for unitary rotational movement of the electrode and the spindle assembly. The electric discharge machining module of the present invention facilitates multiple-spindle or multiple-electrode methods and apparatuses for performing a plurality of EDM operations simultaneously and in close proximity to one another.

摘要： An automated method and apparatus for electrode discharge machining wherein method includes moving the tool holder to the electrode loader, automatically mounting an electrode into the tool holder and then testing the electrode for conformance to geometric and dimension tolerances and testing the electrode for proper alignment in the tool holder and thus proper alignment relative to the workpiece just prior to moving the tool holder to the workpiece area for machining. The apparatus includes a moveable servomechanism with a tool holder, an electrode magazine, and a sensor module for testing an electrode mounted in the tool holder. The sensor module has a recess configuration of conductive material complimentary to the electrode such that the electrode will make contact with the conductive material when inserted into the sensor module if the electrode is out of tolerance or misaligned in the tool holder.

摘要： The technical field of the invention generally concerns electroerosively drilling small diameter holes, e.g. holes 6.0 mm in diameter and smaller. Such a small hole drilling apparatus includes a worktable for receiving a workpiece, together with a chuck and an electrode guide which receives and retains an elongated and thin tubular electrode. The drilling apparatus also includes a fluid supply and pump which delivers a first flow of machining fluid to an inner bore of the tubular electrode at a pressure of at least 20 kg/cm.sup.2. The drilling apparatus also includes a power supply for applying a series of electrical machining pulses between the tubular electrode and the workpiece. As material is removed from the workpiece, an electrode feed mechanism included in the drilling apparatus advances the tubular electrode into the workpiece to maintain the spacing between the tubular electrode and the workpiece. The improved drilling apparatus includes a secondary machining fluid control and a flushing nozzle which directs a second flow of the machining fluid along the outer surface of the tubular electrode toward the machining gap. As the tubular electrode pierces through the workpiece, the second flow of machining fluid keeps the space between the electrode's outer surface and the workpiece including the machining gap filled with machining fluid.
