The Drill 300 from AgieCharmilles is a hole-drilling EDM that machines holes in various diameters and workpiece materials. It employs electrodes ranging from 0.012 to 0.12 in. ( mm) in diameter and incorporates several advanced technologies to precisely machine tough materials, including Inconel, titanium, steel and carbide.
Equipped with a powerful ISPG generator, the machine delivers efficient pulses that significantly increase drilling speeds and productivity. The generator also employs process control strategies that include first spark detection, electrode wear compensation, breakthrough detection and cylindricity control.
The Drill 300 has an ample Z axis travel of 17.72 in. (450 mm) to maximize autonomy and a +/- 45? tilting head to drill angled holes. Machine axis movement speeds reach a maximum of 4/m/min. Furthermore, its six axis configuration makes it possible to drill round and shaped cooling holes on aerospace blades and vanes, while its indexing table also allows for the production of holes in a circular pattern.
The machine automatically controls its dielectric water temperature and conductivity, and the filtration system is in the standard configuration, ensuring stable machining. Additionally, an automatic electrode guide changer as well as an external handling device can assist in configuring the machine.
Designed for ease of use, it features remote control for all setup cycles, axis movements during alignments and for tool changer control when preparing electrodes/guides. Programming is simplified for single holes, multi-pieces and multi-holes with various technologies and electrodes/guides.
The machine fits into most size facilities with its space-saving footprint of 55.12 in. (1400 mm) wide (74.8 in./1900 mm with tilting head) x 91.34 in. (2320 mm) deep x 85.83 in. (2180 mm) high, its compact fixed table design and integrated electrode and dielectric unit.
