THE HIGHEST ACCURACY LEVEL OF FEATURE SIZE AND LOCATION.

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.

Applications for the EDFH1 fine-hole EDM include the medical and electronics industries, as well as the emerging micro-machining market.

Makino is dedicated to providing the most advanced machines and technology to meet and exceed industry requirements.  Makino’s EDM Hole Drilling machines are feature packed, are well suited for production, and deliver high performance levels that matter to your operations.  Several EDM Hole Drilling models are available, and range in capability to support any application.

EDM Hole Drilling machines that are dedicated to high volume production are offered, as well as a versatile machine platform that can perform both EDM Hole Drilling and standard RAM EDM operations. All of Makino’s EDM Hole Drilling machines feature a programmable W-Axis arm unit that supports and positions the electrode die guide for improved part accuracy. Additional design elements that impact EDM Hole Drilling include ATC (Automatic Tool Change) and AGC (Automatic Guide Change) capability, and a Middle Guide system that supports the electrode tube during small diameter hole machining. These features greatly extend unattended machine operations and increase productivity.

Common machine uses are for precision EDM Hole Drilling of diameters below 0.010” (0.250mm) diameter while being able to repeatedly size and produce accurate features.  Typical machine uses include the Aerospace and Power Generation industry, to the Medical and Electronics manufacturing, and Micro Machining applications.
