Machine Comparison
Makino EDAF3 vs Makino EDAF3-FH
Makino vs Makino · Sinker EDM
Summary
The Makino EDAF3 and Makino EDAF3-FH are the same size of sinker EDM. Both list 450 mm (17.7 in) of X travel, Y and Z travel of 351 mm against 350 mm (13.8 in on both), a 700 x 500 mm table, an 800 kg workpiece rating and rapid traverse of 5,000 mm/min (197 ipm). The table gives neither machine an edge on any row.
The difference is the process each one is set up for. The EDAF3 is the cavity sinker for large mold and die work, with heavy electrodes and multi-electrode runs on its ATC. The EDAF3-FH adds EDM hole drilling, so one machine covers sinker work and the critical small holes found in die and mold work and in automotive, medical and aerospace parts.
Specifications Comparison
| Specification | Makino EDAF3 | Makino EDAF3-FH |
|---|---|---|
| X-Axis Travel | 450 mm (17.7 in) | 450 mm (17.7 in) |
| Y-Axis Travel | 351 mm (13.8 in) | 350 mm (13.8 in) |
| Z-Axis Travel | 351 mm (13.8 in) | 350 mm (13.8 in) |
| Table Size | 700×500 (27.5 in x 19.7 in) | 700 x 500 mm (27.5 in x 19.7 in) |
| Max Table / Workpiece Load | 800 kg (1,764 lb) | 800 kg (1,760 lb) |
| Rapid Traverse | 5,000 mm/min (197 ipm) | 5 m/min (197 in/min) |
Advantages
Makino EDAF3
- Set up for cavity sinking with heavy electrodes and unattended multi-electrode runs on an ATC
- Suited to large, deep mold and die cavities
Makino EDAF3-FH
- Adds EDM hole drilling to ram EDM sinking on one machine
- Suited to fine holes in automotive, medical and aerospace production parts
Verdict
With matching envelopes, table and workpiece rating, choose by process. A mold and die shop sinking large, deep cavities with heavy electrodes should choose the Makino EDAF3. A shop that also drills critical small holes, in die and mold work or in automotive, medical and aerospace parts, should choose the Makino EDAF3-FH, which does both on the same 700 x 500 mm table and 800 kg rating.
