Overview
The Makino EDAF2 is the mid-range workhorse in Makino's sinker EDM lineup, built for die and mold shops that need a balance of precision, automation capability, and work envelope for everyday cavity burning. It sits between the compact EDAC1 and the larger EDAF3, hitting the sweet spot for shops that produce injection molds, stamping dies, and precision tooling components in the small-to-medium size range.
Axis travel measures 350 x 250 x 250 mm (13.8 x 9.8 x 9.8 in) on X/Y/Z, with a 500 x 350 mm (19.7 x 13.8 in) worktable rated for 500 kg (1,102 lb). The three-sided programmable drop tank (650 x 500 x 350 mm internal) provides unrestricted access for loading workpieces and integrating automation. When the tank drops, setup and inspection are straightforward, and the design accommodates robotic electrode loading for unmanned operation.
Makino's Hyper-i touchscreen control runs the show with guided setup that builds burn strategies from workpiece and electrode descriptions. The control includes HyperCut technology for reduced electrode wear, SuperSpark IV for optimized metal removal, and ArcFree arc-prevention that detects and kills destructive DC arcs before they damage finish surfaces. These technologies work together to produce consistent cavity finishes with minimal operator intervention.
The NC power supply delivers 30A peak current through an MGH5 unit — enough for productive roughing in most die/mold applications while maintaining the finish capability needed for precision cavities. The standard 16-position ATC supports multi-electrode strategies, and the optional C-axis MA head running up to 1,000 RPM enables orbital burning and electrode rotation.
Rapid traverse runs at 5,000 mm/min (197 ipm). Machine weight sits at approximately 4,200 kg (9,259 lb) with a 1,350 x 2,350 mm (53.1 x 92.5 in) footprint. The integrated dielectric reservoir saves floor space. New machines typically price between $100,000 and $155,000 depending on options. Used EDAF2 machines from 2013-2020 trade between $35,000 and $70,000. Forum users consistently praise the Hyper-i control's intuitiveness and the machine's surface finish consistency.

Strengths & Limitations
Strengths
- Sweet-spot sizing for die/mold shops — 350 x 250 mm travel covers the majority of small-to-medium cavity work without paying for excess capacity
- Hyper-i touchscreen control with guided setup builds effective burn strategies from simple workpiece and electrode descriptions
- ArcFree technology actively prevents destructive DC arcs, protecting surface finish quality during unattended overnight burns
- Three-sided programmable drop tank enables easy workpiece access and supports integration with robotic electrode loading systems
- HyperCut technology reduces electrode wear, achieving target finishes with fewer electrodes per cavity and lowering consumable costs
- 16-position ATC with optional C-axis MA head supports complex multi-electrode strategies for unattended production
Limitations
- 350 x 250 mm X/Y travel limits the machine to small-to-medium cavities — shops needing larger strokes should look at the EDAF3
- 30A peak current is adequate for most die/mold work but not ideal for heavy roughing of large cavities where higher power accelerates material removal
- Premium Makino pricing ($100K-$155K new) is significantly above entry-level sinker EDMs from CHMER or LSEDM
- Best accuracy requires climate-controlled environment — shops without temperature control won't see the machine's full capability
- Makino's service network is smaller than Sodick or Mitsubishi in some regions, potentially affecting response times

Frequently Asked Questions
01
New EDAF2 machines typically run $100,000-$155,000 depending on configuration. A base machine with 16-tool ATC starts around $100,000. Adding the C-axis MA head, fine-hole option, high-pressure filtration, and fire suppression pushes the price to $130,000-$155,000. Used EDAF2 machines from 2013-2020 sell between $35,000 and $70,000. A 2018 unit with low hours typically commands $55,000-$70,000.
02
The EDAF3 offers larger X/Y/Z strokes (450/350/350 mm vs 350/250/250 mm), a bigger worktable (700 x 500 mm vs 500 x 350 mm), higher workpiece capacity (800 kg vs 500 kg), and a more powerful 40A MGH6 power supply vs the EDAF2's 30A MGH5. The EDAF3 weighs about 1,200 kg more. Choose the EDAF2 for small-to-medium work where its travel is sufficient; choose the EDAF3 when you need the extra reach and power.
03
Yes. The three-sided programmable drop tank is specifically designed for automation integration. When the tank drops, there's clear access for robotic electrode loading. The 16-position ATC handles multi-electrode sequences, and the Hyper-i control manages burn scheduling and electrode sequencing. Many shops run the EDAF2 in robotic cells with Erowa or System 3R palletization for lights-out operation.
04
With optimal electrode selection and multi-pass finishing, the EDAF2 achieves VDI 10-12 (approximately 0.4-0.8 um Ra) for standard die/mold work. With HyperCut technology engaged and fine-finish parameters, finishes below VDI 10 (0.3 um Ra) are achievable. The practical finish quality depends heavily on electrode material (graphite vs copper), dielectric condition, and workpiece material.
05
The standard EDAF2 is sinker-only. However, Makino offers the EDAF2-FH (Fine Hole) variant that adds a removable W-axis die guide arm for precision EDM hole drilling. The arm installs and removes quickly, providing both sinker and drilling capability on one machine. The Fine Hole option uses EDM dielectric oil and can drill holes down to 0.1 mm diameter.
