Abstract
A wire cut electric discharge machining apparatus cannot maintain high machining accuracy because the arm may expand/contract as it receives more heat from the machining fluid. The wire cut electric discharge machining apparatus has guide parts that guide a wire and arms that support the guide parts, wherein at least one of the guide parts has a machining fluid ejection nozzle, and at least one of the arms has an ejection connection pipe and a thermal insulation part. The ejection connection pipe is a hole penetrating the arm and supplies the machining fluid to the machining fluid ejection nozzle, and the thermal insulation part covers the inner peripheral surface of the ejection connection pipe to thermally insulate the inner hole of the ejection connection pipe.
Claims6
A wire cut electric discharge machining apparatus, comprising guide units having respectively a guide that guides a wire and arms that support the guide units,
- wherein at least one of the guide units comprises a machining fluid ejection nozzle that ejects a machining fluid, and
- at least one of the arms comprises an ejection connection pipe and a thermal insulation, wherein the ejection connection pipe is a hole penetrating the arm and is at least a part of a flow path that supplies the machining fluid to the machining fluid ejection nozzle, and the thermal insulation has a smaller thermal conductivity than the arm and covers an inner peripheral surface of the ejection connection pipe to thermally insulate an inner hole of the ejection connection pipe.
