Machine Comparison
Makino BX3 vs Makino EDAC1
Makino vs Makino · Sinker EDM
Summary
The Makino BX3 and Makino EDAC1 are both listed as sinker EDMs, but they serve different jobs. The BX3 is an EDM drilling machine for cooling film holes in turbine blades and vanes, and it works on a rotary table rather than a fixed work table. The EDAC1 is a small precision sinker for electronics components, micromachining and fine cavities, with a 350 x 250 mm (13.8 in x 9.8 in) table.
The BX3 has more travel on every axis: 370 mm (14.6 in) X, 270 mm (10.6 in) Y and 750 mm (29.5 in) Z against 220 mm (8.66 in), 180 mm (7.08 in) and 220 mm (8.66 in). The EDAC1 takes the heavier workpiece, 50 kgs (110 lb) against 20 kg (44 lb).

Advantages
Makino BX3
- 750 mm (29.5 in) Z travel against 220 mm (8.66 in)
- 370 mm (14.6 in) X and 270 mm (10.6 in) Y travel against 220 mm (8.66 in) and 180 mm (7.08 in)
- Rotary table on A and B axes for drilling holes at many angles in blades and vanes
Makino EDAC1
- 50 kgs (110 lb) workpiece load against 20 kg (44 lb)
- 350 x 250 mm (13.8 in x 9.8 in) work table for small precision parts
- Built for fine cavities, slots and surface finishing on small electronics and micromachined parts
Verdict
Pick by process, not by size. The Makino BX3 suits aero-engine shops drilling cooling film holes in turbine blades and vanes, including holes that break into hollow internal cavities, where the rotary table and 750 mm (29.5 in) of Z travel apply. The Makino EDAC1 suits micromachining of small electronics parts and fine cavities with tight depth tolerances, on a 350 x 250 mm table carrying up to 50 kgs (110 lb).
