    摘要: The invention relates to a method and generator for generating a time sequence of EDM pulses having a predefined ignition voltage for electrical discharge machining. An AC voltage is generated from a DC voltage, furnished by a bipolar current source. The AC voltage is applied to an isolating transformer disposed between the bipolar current source and the spark gap. A first pulse capacitor is charged by the bipolar current source to a voltage corresponding to the ignition voltage. The ignition voltage provided by the isolating transformer is switched with a selected polarity to the spark gap.

    摘要: The invention relates to a method and a generator for generating a time sequence of discharge pulses separated from each other by pulse pauses for electrical discharge machining. At least two pulse capacitors are discharged each in the form of a partial pulse into the spark gap for forming together a discharge pulse. A discharge pulse having a predetermined waveform is selected from a plurality of discharge pulses having differing predetermined waveforms. The discharge of the at least two pulse capacitors is controlled such that the selected discharge pulse is generated with the predetermined waveform.

    摘要: The invention relates to a method and a generator for generating a time sequence of discharge pulses for EDM machining wherein a pulse capacitor (22) for generating the discharge pulse is charged with a charging voltage (U_chrg) and then discharged into the spark gap. The pulse capacitor (22) after being discharged is recharged with a charging voltage (U_chrg) having the same polarity as that of the residual voltage (U_end) remaining at the pulse capacitor (22) after its discharge. Thereafter, the pulse capacitor (22) is discharged with a discharge pulse into the spark gap, wherein the polarity of the discharge pulse is independent of the polarity of the charging voltage (U_chrg) at the pulse capacitor (22) after its recharge.

    摘要: The invention relates to a circuit board unit and a method for production thereof. The circuit board unit comprises a circuit board topmost laminate with conductive tracks on the upper side for mounting surface-mountable devices. The circuit board topmost laminate features a thickness dimensioned such that the anticipated heat dissipated by the surface-mountable devices is transported from the upper side to the underside of the circuit board laminate to good effect. The circuit board unit further comprises an electrically insulating laminate arranged under the circuit board topmost laminate, inserts made of a material with good heat conductivity and electrical insulation embedded in the electrically insulating laminate at sites below surface-mountable devices with high heat dissipation, and a cooling plate arranged below the electrically insulating laminate and the inserts.

    摘要: A method of precision electric-discharge machining carried out in apparatus of moderately high precision and stability with an electrode in the form of a wire. The object is a surface as smooth as the surface that can be obtained with the more expensive very high-precision apparatus. The contour of work that has already been roughed out at least once is accordingly exploited as a geometrical reference for at least one finishing cut. The gap is maintained constant by fine adjustments.
