Electrical discharge machine

摘要

#CMT# #/CMT# Electrode jumping (amount (23) of jumping of a second electrode) is performed, in which the jumping amount is set so that balls or rollers used for a slide portion of a machine drive part makes one turn or more in addition to electrode jumping (amount (22) of jumping of a first electrode) for discharging the chips produced during the discharge machining. #CMT# : #/CMT# When a lubricant feeding device (101) is detected to be abnormal, the machining is suspended after the program ends or after a predetermined period of time. When the program is other than the machining programs, the execution of the program is continued. #CMT#USE : #/CMT# Electrical discharge machining.
