When it comes to single or multi-hole high-speed EDM drilling, the Engineering Technology Group (ETG) says it is breaking the boundaries of convention with the introduction of the Winbro HSD6-III high-speed EDM drilling system.

Designed and manufactured in the UK by the Winbro Technologies Group, the HSD6-III high-speed EDM system is said to offer industry-leading performance while maintaining stringent metallurgical requirements that are commonplace in the aerospace and IGT markets. Winbro’s HSD6-III is for the machining of cooling holes, forms and features in turbine blades, nozzle guide vanes, seal segments and other components that require high-speed EDM drilling. The machine is capable of producing round, elliptical and 2D/3D shaped diffusers.

Offering production rates up to five times faster than conventional EDM machines, the Winbro HSD6-III is suitable for processing round holes from 0.3 to 3 mm diameter with a maximum depth up to 100 mm. Precision is assured with Winbro’s advanced and patented six-point probing system.

The work envelope of the Winbro HSD6-III offers an X, Y and Z axis of 200 x 200 x 250 mm that can accommodate workpieces up to 225 x 225 x 225 mm. In addition, the rotary A axis of ±185°, B axis of 135° +100° and a rotary C axis of ±8° enables component interpolation for complete five-sided part processing in a single set-up.

The tooling configuration of the Winbro HSD6-III is flexible to suit the demands of the end-user with the choice of a single-point rotational or static electrode for non-line-of-sight, or (for high-productivity environments) a multi-tool option with up to 45 sensed electrodes.
