In a wire discharge machine, threading of the wire is accomplished by tensioning the wire to straighten same and applying an electric current thereto to facilitate separation thereof. Clamps hold and help tension the wire by securing one or more ends at a particular location. The tensioning is accomplished with drive motors, which may be or include pulse motors.

Wire cutting electric discharge machine

A wire cutting electric discharge machine that has wire supply rollers 17A and 17B feed the wire at a first speed and a wire feed out section that conveys the wire to a scrap box at a second speed that is greater than the first speed. Detection of the wire successfully reaching a wire guide section on the wire take out side is accomplished by detecting the speed of movement of a wire supply roller to see when it exceeds a preset fixed speed of movement.
