Machine Comparison
Makino EDBV8 vs Makino EDFH-1
Makino vs Makino · Sinker EDM
Summary
The Makino EDBV8 and Makino EDFH-1 are EDM machines for different jobs. The EDBV8 drills film-cooling holes and diffusers in turbine blades and vanes, holding the part on an A/B rotary table (A: 360° / B: -110/+30°). The EDFH-1 is a small machine for precision parts on a fixed 350 x 250 mm table.
The EDBV8 has far more travel: 800 mm (31.5 in) of X, 600 mm (23.6 in) of Y and 500 mm (19.7 in) of Z against 220 mm (8.7 in), 180 mm (7.1 in) and 300 mm (11.8 in). Both are rated for 50 kg (110 lb) as standard; the EDBV8's rotary table can take 150 kg (330 lb) as an extra-cost option. The EDBV8 lists 24 tools; the EDFH-1 lists 8 or 16.

Advantages
Makino EDBV8
- 800 mm (31.5 in) of X and 600 mm (23.6 in) of Y travel against 220 mm (8.7 in) and 180 mm (7.1 in)
- 500 mm (19.7 in) of Z travel against 300 mm (11.8 in)
- A/B rotary table reaches hole patterns on several faces in one setup
Makino EDFH-1
- A compact machine for small precision parts that fit 220 x 180 mm of X and Y travel
- Fixed 350 x 250 mm table for parts that do not need rotary positioning
Verdict
These machines are not alternatives for the same part. Choose the Makino EDBV8 for turbine blade and vane work in aerospace and power generation, where 800 mm of X travel and the A/B rotary table reach holes on several faces in one setup. Choose the Makino EDFH-1 for small precision parts that fit 220 x 180 mm of X and Y travel and weigh up to 50 kg, where the larger machine would add nothing.
