Multi hole drilling machining system is for producing multiple cooling holes in turbine blades and vanes.This drilling machine has capability to produce straight,shaped and slotted holes. The dielectric can either be traditional oil based fluids or de-ionised water for repid machining rates.The programmable controller allows for full parameter control hole during the Drilling cycle and the ability to change process parameters with depth,thus optimising the process in all areas 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.Use of Cassette type tooling enables rapid change-over between operations.The tank fill time of 8 seconds and drain time of 4 seconds minimizes non cuting time on this production system.
