Makino now offers a high-accuracy fine-hole machining configuration on the ultra-precision EDAC-1 sinker EDM platform. The EDFH1 is a re-configured EDAC-1 machine that incorporates a fine-hole machining guide arm, high-speed rotating spindle capable of 2,000 rpm, and a high-pressure pump for flushing through small diameter tube electrodes.

The EDFH1 fine-hole EDM uses a highly advanced generator that produces the world’s smallest spark gap and best possible surface finish. The platform shares the same dual utility capability as the EDAF-Series fine-hole machines, and can operate in both EDM drilling or standard sinker EDM modes. The EDFH1 also uses the same unique tooling system as the EDBV3 machine, which integrates the die guide and tube electrode into one common assembly that provides automatic tool change and guide changing capabilities.
