Abstract
A fine hole electric discharge machine includes a machining tank, a storage tank, at least one pipeline, a guide base, a liquid current generator, and a controller. The at least one pipeline has at least one opening directed to the upper surface of a workpiece and allows machining liquid to flow through. The liquid current generator selectively forms a first liquid current in which the machining liquid is supplied from the storage tank and jetted from a predetermined opening of the opening, or a second liquid current in which the machining liquid is sucked from an opening the same as or different from the predetermined opening and recovered to the storage tank. The controller controls the liquid current generator to form the first liquid current or the second liquid current.
Claims14
A fine hole electric discharge machine, generating an electric discharge in a machining gap formed between a tool electrode and a workpiece to machine a hole in the workpiece, the fine hole electric discharge machine comprising:
- a machining tank accommodating the workpiece;
- a storage tank storing machining liquid;
- at least one pipeline which has at least one opening directed to an upper surface of the workpiece and through which the machining liquid flows;
- a guide base comprising a lower guide which positions and guides the tool electrode;
- a liquid current generator selectively forming a first liquid current or a second liquid current, wherein the first liquid current is the machining liquid which is supplied from the storage tank and jetted from a predetermined opening of the at least one opening, and the second liquid current is the machining liquid which is sucked from an opening the same as or different from the predetermined opening of the at least one opening and recovered to the storage tank;
- and
- a controller controlling the liquid current generator to form the first liquid current or the second liquid current.
