The Electrical Discharge Blades and Vanes (EDBV3) machine uses specially designed 2-axis tool approaches and quick-change tool magazines to rapidly drill holes in blade and vane workpieces for aerospace applications. The EDBV3 uses EDM (electrical discharge machining) technology, in which a rapid discharge of electrical sparks cut metal, to produce holes up to 0.008 in (0.200 mm) in diameter. The machine places the workpiece underwater during automatic drilling operations, which provides numerous benefits. The drill can operate at speeds up to 10 times as rapid as standard drills, while avoiding spills or clutter, all of which ensures higher-precision drilling.
The machine features a 1,000 rpm spindle, which spins the workpieces for the aforementioned multi-angle drill toolpiece approaches. The X access operates in a 14.56 in work envelope, the Y axis at a 10.62 in envelope, and the Z at a 19.68 in envelope. Work pieces as large as 11 pounds can be machined on the standard unit, though an upgrade to a rotary table that can manage 33 pound pieces is available.
The EDBV3 can be used on automatic, lights-out settings, or under the direct supervision and guidance of an operator. (via Frost & Sullivan Technical Insights group.)
