# Makino EDBV3

Hardware · `EDBV3` · verification: source checked

The Makino EDBV3 is an EDM hole-drilling machine for blade and vane cooling holes and diffusors. It drills fully submerged in de-ionized water and has X/Y/Z travels of 370/270/500 mm, a 2-axis rotary table, and a 24-position automatic tool changer. A break-through detection circuit stops back-striking when drilling into hollow cavities.

## Safety

- Break-through detection circuit prevents back-striking when EDM drilling into hollow cavities; detection occurs within 1 second or 0.040 in (1.0 mm) of depth.
- Fully submerged machining in de-ionized water minimizes water over-spray and eliminates the splash guards used on traditional EDM drilling machines.
- Middle Guide system supports long electrodes during machining to prevent whipping or bending.

## Study notes

- Uses Makino Hyper-i control with Windows 7 and a 24-inch class high-definition touch interface.
- Control includes pre-programmed cycles for diffuser shapes, intelligent electrode length management, and multiple graphical pick-up cycles.
- Die Guide and Electrode tooling are loaded and exchanged together as an assembled unit; combined ATC and AGC exchange time is within 30 seconds.
- The dielectric reservoir is integrated into the base casting; water quality is maintained by an on-board chiller, water filtration, and de-ionization systems.
- The programmable 3-sided Rise and Fall work tank provides unrestricted access to the work tank for load/unload and automation.
- Maximum workpiece weight is 5 kg standard, with a 15 kg optional rotary table.
- Tank size is 790 x 611 mm (31.1 x 24.1 in).
- The machine is configured with an integrated 2-axis rotary table for positioning the workpiece to access multiple sides in a single setup.
