Machine Comparison
Makino EDAF2 vs Makino EDAF2-FH
Makino vs Makino · Sinker EDM
Summary
The Makino EDAF2 and Makino EDAF2-FH share an X/Y envelope and a workpiece rating: 350 mm (13.78 in) of X travel, 250 mm (9.8 in) of Y travel and 500 kg (1,100 lb) on the table. The EDAF2 is the standard sinker EDM for mold and die cavities; the EDAF2-FH adds fine-hole drilling, so sinker work and hole drilling run on one machine.
The EDAF2-FH has more Z travel, 350 mm (13.8 in) against 250 mm (9.8 in). The EDAF2 takes heavier electrodes, 75 kgs (165 lb) against 50 kg (110 lb). The tables differ slightly: 550 × 350 mm (21.65 in x 13.78 in) on the EDAF2 against 500 x 350 mm (19.7 x 13.8 in) on the EDAF2-FH.

Advantages
Makino EDAF2
- Electrodes up to 75 kgs (165 lb) against 50 kg (110 lb)
- Suited to long, unattended sinking runs with an added ATC or automation
Makino EDAF2-FH
- 350 mm (13.8 in) of Z travel against 250 mm (9.8 in)
- Drills fine holes as well as sinking cavities, so one machine covers both jobs
Verdict
Choose the Makino EDAF2 for straight mold and die sinking, especially with heavy electrodes up to 75 kgs, or for unattended work with an ATC. Choose the Makino EDAF2-FH when the same shop also needs fine holes drilled in mold or production parts, or needs the extra Z: it gives 350 mm against 250 mm while keeping the same 500 kg workpiece rating.
