Improved wire cut electrical discharge machine tool

Abstract

The invention relates to an improved wire cut electrical discharge machine tool which comprises a machine tool body and a control cabinet. The machine tool body at least comprises a tool body, a wire electrode conveying mechanism, a wire support, a work table, a working solution system, a power supply system, a machine tool electric appliance and a numerical control system. The power supply system comprises a high-frequency pulse power generating device. The wire support comprises a column, an upper arm and a lower arm. An upper main guide wheel and an upper electric conduction block are arranged on one side of a machining area of the upper arm, a lower main guiding wheel and a lower electric conduction block are arranged on one side of a machining area of the lower arm. The high-frequency pulse power generating device is arranged in a power supply cabinet, the power supply cabinet is arranged on one side of the column, a positive pole of generated high-frequency pulse power is connected with the work table of the machine tool body through a lead, and a negative pole of the generated high-frequency pulse power is connected with the upper electric conduction block on one side of the upper main guide wheel and the lower electric conduction block on one side of the lower main guide wheel of a machining area of the machine tool through an upper lead and a lower lead respectively. The distance between the high-frequency pulse power and the upper electric conduction block and the distance between the high-frequency pulse power and the lower electric conduction block are greatly shortened and can be approximately shortened by half, voltage loss in a conveying process is small, and machining efficiency of the machine tool is remarkably improved.
