Tube electrode stabilizer for an EDM drilling

摘要

A tube electrode stabilizer for an EDM drilling includes a stabilizer block and a mover. The stabilizer block has a concaved in shaped supporting wall that parallels to the traveling path of a tube electrode, and has a plurality of apertures interconnected to air vacuuming connections to suck air. The mover is connected to the stabilizer block for approaching the tube electrode. Suction force pushes the tube electrode against the supporting wall to achieve stabilization of the tube electrode. The stabilizer block further has a sensor to detect whether the tube electrode is seated into the stabilizer block or not and to measure the available length of the tube electrode before or after drilling.
