WIRE ELECTRIC DISCHARGE MACHINE

摘要

A wire electric discharge machine includes a wire electrode fed downward to a workpiece to perform electric discharge machining, a direction changing unit that changes a traveling direction of the wire electrode below the workpiece, a collection roller that collects the wire electrode, the traveling direction of which is changed, an extendable conveying pipe provided between the direction changing unit and the collection roller, the wire electrode being inserted through the inside of the conveying pipe, a supply unit that supplies the machining fluid into the conveying pipe, a supply-amount-information detecting unit that detects information concerning a supply amount of the machining fluid supplied to the conveying pipe, and a control unit that controls supply capacity for feeding the machining fluid to the conveying pipe from the supply unit on the basis of the information from the supply-amount-information detecting unit.

1. A wire electric discharge machine comprising:
a wire electrode fed downward to a workpiece to perform electric discharge machining; a direction changing unit that changes a traveling direction of the wire electrode below the workpiece; a collection roller that collects the wire electrode, the traveling direction of which has been changed; an extendable conveying pipe, which is provided between the direction changing unit and the collection roller, and inside of which the wire electrode is inserted through; a supply unit that supplies the machining fluid into the conveying pipe to cause the machining fluid to flow in the conveying pipe from the direction changing unit side toward the collection roller side; a supply-amount-information detecting unit that detects information concerning a supply amount of the machining fluid supplied to the conveying pipe; and a control unit that controls supply capacity for feeding the machining fluid to the conveying pipe from the supply unit on the basis of the information from the supply-amount-information detecting unit.
