The EDBV3 (Electrical Discharge Blade and Vane) machine has been specifically designed for the demanding EDM Drilling requirements for blade and vane machining found in the aerospace and power generation industries. The machine has been purpose built to deliver top performance and optimal speed while preventing internal work piece back-striking in the drilling of cooling film holes and diffusors. The EDBV3 performs all machining fully submerged in de-ionized water to achieve the fastest cycle times and with the most stable hole break-thru operation. Submerged operation also improves shop safety by minimizing water over-spray and eliminates the cumbersome splash guards found on traditional EDM Drilling machines. The EDBV3 also provides unrestricted access to the work tank with the programmable 3-sided Rise and Fall work tank system, which affords ergonomic load/unload operations while simplifying automation requirements.
The EDBV8 (Electrical Discharge Blade and Vane) machine expands on the X/Y/Z stroke capacities of the smaller EDBV3, and has been designed with a focus on EDM Drilling of turbine engine components. Reliability and consistent quality are an essential performance attribute to production EDM Drilling of blade and vane details found in power generation and aerospace applications, and the EDBV8 contains many unique technologies that minimize process variations. All machining is performed fully submerged, which facilitates faster and more stable machining, and eliminates the need for traditional manual setup of cumbersome splash guards while preventing shop safety slip hazards caused by water over-spray.
