More Information
Summary:Separately from an electrode jumping operation (an amount of rise of a first electrode jump (22)) aimed at discharging machining debris produced during electrical discharge machining, an electrode jumping operation (an amount of rise of a second electrode jump (23)) is inserted for which is set an amount of rise of jump with which balls or rollers used on a sliding portion of a mechanically driving part undergo one revolution or more. Further, in a case where an abnormality of a lubricant supplying unit (101) is detected, as for a program being continued, machining is stopped after the termination of the program, or machining is stopped after continuing the program within a fixed time duration, or a program other than for machining operation is made executable.
