Embodiment Construction

[0030] figure 1 It is a schematic block diagram showing one embodiment of the wire electric discharge machine of the present invention.

[0031] In the wire electric discharge machine, a voltage is applied between a workpiece placed and mounted on a table (not shown) provided on the mechanism part 10 and a wire electrode (not shown) to generate a discharge, and the wire electrode is opposed to the wire electrode. The workpiece is moved, whereby electrical discharge machining is performed on the workpiece. In addition, when rapidly accumulating the machining fluid in the machining tank 3 , it is performed through the rapidly accumulating machining fluid supply path 12 . Subsequent replenishment of the machining fluid is performed through the machining fluid supply path L1a. The machining fluid in the machining tank 3 is supplied to the waste water tank 8 mixed with machining debris and the like generated by electric discharge machining.

[0032] The machining fluid recovered...

Abstract

The present invention provides a wire-cut electric discharge machine having water level abnormality detection function and water level abnormality alarm generation cause specifying method. For specifying a cause of generation of a water level abnormality alarm in a wire-cut electric discharge machine, stopping supply of a machining liquid to a machining tank when the alarm is generated, draining the liquid; measuring an amount of change in the water level per unit time that is detected by the water level detecting unit; and displaying a question to an operator about the measured amount of change in water level and the state of a water level adjusting mechanism. The operator manually inputs an answer to the displayed question, and specifies, from the answer input by means of the inputting unit, a part which causes the generation of the alarm.

Description

technical field [0001] The invention relates to a wire electric discharge cutting machine with an abnormal water level detection function and a method for determining the cause of an abnormal water level alarm. Background technique [0002] There are two types of wire-cut electric discharge machines. One of them is a jet type in which machining is performed while spraying machining fluid onto the wire electrode from nozzles attached to inlets and outlets of upper and lower wire guides without filling the machining tank with machining fluid. The other is the immersion type that fixes the workpiece in the processing tank and fills the processing tank with processing fluid to improve the processing speed and processing accuracy, and the processing is performed while the workpiece is soaked. [0003] In the immersion type wire electric discharge machine, since it is necessary to change the water level of the machining tank according to the height of the workpiece, various water...
