The EDFH-1 is built with reliable long-term mechanical precision in mind

The EDFH-1 machine expands on the advanced ultra-precision capability of the EDAC-1 by incorporating high-accuracy EDM Drilling to the same machine platform.  The EDFH-1 is capable of performing high accuracy standard Ram EDM processing, and can achieve surface finishes  down to  1.3µin Ra (0.25µmRz). 

The machine’s refined generator can produce inside corner radii as small as 5 microns (0.0002”), and the Z-Axis Jump Speed of 10m/min (394”/min) provides efficient high speed machining while maintaining a ±1 micron depth control capability using a core-cooled ball screw. 

The included high speed C-Axis provides rotation speeds up to 2,000rpm, and the programmable W-Axis provides rigid alignment for EDM Drilling Die Guides and also features a Middle Guide Arm to support and prevent vibration of small diameter electrodes with flushing pressures up to 10Mpa (1,450 psi).
