Machine Comparison
Makino EDBV3 vs Makino EDBV8
Makino vs Makino · Sinker EDM
Summary
The Makino EDBV3 and Makino EDBV8 are both EDM hole drillers for cooling holes and diffusers in turbine blades and vanes, but they serve different part sizes. The EDBV8 has 800 mm (31.5 in) of X and 600 mm (23.6 in) of Y travel against 370 mm (14.6 in) and 270 mm (10.6 in) on the EDBV3. Its rotary table is rated for 50 kg (110 lb), or 150 kg (330 lb) as an extra-cost option, against 5 kg (11 lb), or 15 kg (33 lb) as an option.
The rest is shared: both list 500 mm (19.7 in) of Z travel, the same A: 360° / B: -110/+30° rotary table, 24 tools and rapid traverse of 5 m/min (197 in/min). Part size is the whole difference.

Advantages
Makino EDBV3
- Covers small blades and vanes that fit 370 mm (14.6 in) of X travel
- Same 24 tools, 500 mm of Z and rotary table range as the larger EDBV8
Makino EDBV8
- 800 mm (31.5 in) of X and 600 mm (23.6 in) of Y travel against 370 mm and 270 mm
- Rotary table rated for 50 kg (110 lb), or 150 kg (330 lb) as an option, against 5 kg (11 lb) or 15 kg (33 lb)
Verdict
Choose by part size. The Makino EDBV3 fits small turbine blades and vanes that stay within its 5 kg rotary table rating, or 15 kg with the option. The Makino EDBV8 takes larger blade and vane details up to 50 kg, or 150 kg with the option, and gives 800 mm of X travel for hole patterns spread across bigger parts. Both share 500 mm of Z and 24 tools, so size alone decides.
