摘要： An EDT apparatus 1 is disclosed, comprising a dielectric fluid return system for use with an EDT machine of the type in which the workpiece is not submersed in dielectric fluid. The return system comprises a first collector 19 for catching spills from a dielectric bath 9 associated with a set of electrodes 10 which apply electrical pulses to the workpiece through the dielectric fluid in the bath. Also, a separate, second collector 21 is positioned substantially beneath the workpiece and arranged both to receive fluid from the first collector 19 and to catch fluid that drips from the workpiece itself, the second collector being connected to a pump 13 which returns the fluid from the second collector to the dielectric bath.

摘要： A method of machining a work-piece formed of titanium-based material, using a machining apparatus, is described. The method includes the steps of providing an electrically-conductive electrode contained within a spindle assembly, in a pre-selected distance and position relative to the titanium-based work-piece; while electrically powering the electrode and the work-piece with a power supply. In the process, fluid electrolyte is circulated through at least two pathways in the machining apparatus—an internal conduit within the spindle assembly; and an external conduit. The charged electrode is moved relative to the work-piece in a plunging motion, to remove material from the work-piece at a relatively high rate, using a high-speed electro-erosion (HSEE) process.

摘要： A wire electric discharge machine has a function of estimating the time for replacement of a filter based on a use situation for the machine. A time Tr during which the filter is serviceable is calculated according to an equation, Tr=|(Pd−Pn)/ΔP|, based on a fluid pressure variation amount ΔP, a current filter fluid pressure Pn, and a filter life pressure. A remaining available time Td for the filter which takes into account the operation rate of the machine is calculated according to an equation, Td=Tr/W.

摘要： A seal is brought into contact with a filter media, a filter pump is operated to start filtration, and a signal from a pressure sensor is received. When a predetermined value is exceeded by the signal from the pressure sensor, the filter pump is stopped, the seal is separated from the filter media, and take-up of one section of the filter by a filter collection roll is started. In finishing filter supply from a filter supply roll, drive of a motor is stopped, and an alarm signal is transmitted. If the supply is not to be finished, one section of the filter is taken up by the filter collection roll, and the next stage of filtration is entered.
