Machine Comparison
Makino EDAF3-FH vs Makino EDBV3
Makino vs Makino · Sinker EDM
Summary
The Makino EDAF3-FH and Makino EDBV3 both drill holes by EDM, but they serve different parts. The EDAF3-FH is a ram EDM with hole drilling for die, mold and production parts, on a 700 x 500 mm table rated for 800 kg (1,760 lb). The EDBV3 is built for cooling holes in turbine blades and vanes, and holds the part on a rotary table (A: 360° / B: -110/+30°) rated for 5 kg, or 15 kg as an extra-cost option.
The EDAF3-FH has more X and Y travel, 450 mm (17.7 in) and 350 mm (13.8 in) against 370 mm (14.6 in) and 270 mm (10.6 in). The EDBV3 has more Z, 500 mm (19.7 in) against 350 mm (13.8 in). The EDBV3 lists 24 tools; the EDAF3-FH lists 8, 16 or 32. Both rapid at 5 m/min (197 in/min).

Advantages
Makino EDAF3-FH
- 450 mm (17.7 in) of X and 350 mm (13.8 in) of Y travel against 370 mm and 270 mm
- Combines ram EDM sinking and hole drilling on one machine for die and mold work
Makino EDBV3
- 500 mm (19.7 in) of Z travel against 350 mm (13.8 in)
- A/B rotary table (A: 360° / B: -110/+30°) to reach cooling holes on blade and vane surfaces
Verdict
These machines serve different jobs. Choose the Makino EDAF3-FH for die and mold work and for automotive, medical or aerospace production parts that need critical holes plus sinker work, on parts up to 800 kg. Choose the Makino EDBV3 for turbine blades and vanes that need cooling holes and diffusers, where the rotary table and 500 mm of Z matter and parts stay within its 5 kg rating, or 15 kg with the option.
