Electrical discharge machining apparatus

An electrical discharge machining apparatus at least comprising:

• a carrier platform for carrying at least one to-be-machined object;
• and
• an electrical discharge machining unit for performing an electrical discharge machining procedure on a machined target area of the to-be-machined object on the carrier platform along a machining direction, the electrical discharge machining unit comprising:
• at least one electrode;
• a jig, the jig being formed by correspondingly assembling at least two carrying members and at least two holding members respectively, two sides of the electrode abutting against the two carrying members respectively, so that an electrical discharge section of the electrode being suspended, wherein the electrical discharge section of the electrode extends along a second direction perpendicular to a first direction;
• and
• a power supply unit, the power supply unit providing a first power source to the electrode and the to-be-machined object in the electrical discharge machining procedure for applying an electrical discharge energy to the machined target area of the to-be-machined object through the electrical discharge section of the electrode, wherein when the electrical discharge machining unit performs the electrical discharge machining procedure along the machining direction, the electrical discharge section of the electrode and the machined target area of the to-be-machined object move relatively along the second direction.
