A multi-hole drilling (MHD) EDM machining center for producing multiple cooling holes in turbine blades and vanes. The system has capability to produce straight, shaped and slotted holes. The dielectric can either be traditional oil based fluids or de-ionised water for rapid machining rates.
The Tech-Pulse EDM generator is a mult-mode output type, allowing optimized use of various electrode materials and configurations including: Tungsten electrodes, and Graphite, Brass, or Copper tubes .005″ – .130′”[0,13mm - 3,5mm]. The programmable generator allows for full parameter control during the EDM cycle and the ability to change process parameters with depth, thus optimizing the process in all area’s of the cut. A two axis system allows for shaped holes to be produced using standard rod type electrodes.
The system is designed for volume production; and use of catridge type tooling enables rapid change over between operations. The tank fill time of 8 seconds and drain time of 4 seconds minimizes non cutting time on this production system
