PORTABLE SMALL HOLE ELECTRICAL DISCHARGING MACHINE

摘要

PURPOSE: A portable small hole discharge machine is provided to be optimized the process of deep workpieces by supplying working liquid into a pipe electrode by using a high pressure pump. CONSTITUTION: A portable small hole discharge machine comprises a small hole machining electrode(10), a machine main shaft(20), a step motor(40), and a spindle motor(50). A spindle(21) inserted into the machine main shaft is coupled to the small hole machining electrode to supply working liquid. The machine main shaft moves back and forth according to the rotation of the step motor. A main shaft num is thread-coupled to the machine main shaft. The machine main shaft is driven by the rotating force of the step motor. The spindle motor has a spindle driven gear and a spindle driving gear. The small hole machining electrode is rotated by the rotating force delivered from the spindle driven gear and the spindle driving gear.
