How much does the Mitsubishi Electric EA12PS cost?
Estimated price range
Our best estimate for a sinker edm (ram edm) in this class — not a quote from Mitsubishi Electric. Configuration moves it a long way.
Overview
The Mitsubishi Electric EA12PS is a sinker EDM with travels of 15.7 in (400 mm) in X and 11.8 in (300 mm) in both Y and Z, a 27.6 x 19.7 in (700 x 500 mm) table and a three-sided drop tank. It comes with the FP80PS power supply at 80 A, with the FP120PS at 120 A as an option, and an M700 Series CNC control with a 15 in touchscreen.
The tank is larger than the travels suggest. Internal dimensions are 37.0 x 27.5 x 17.7 in (950 x 700 x 450 mm) and the maximum workpiece is 35.4 x 25.6 x 13.8 in (900 x 650 x 350 mm), so a mold base more than twice as wide as the X travel fits, provided the cavities fall inside the area the head can reach. Table load is 2,200 lb (1,000 kg), the platen carries electrodes up to 176 lb (80 kg), and the dielectric level adjusts from 3.9 to 15.7 in (100 to 400 mm).
Daylight is the row to check against your tooling. Table to platen is 7.9 to 19.7 in (200 to 500 mm). With a C-axis chuck the figure depends on the chuck system: 7.9 to 19.7 in (200 to 500 mm) for EROWA ITS and 7.2 to 19.0 in (183 to 483 mm) for 3R Macro.
Axis motion is specified in unusual detail. Rapid traverse is 275.5 in/min (7 m/min), but the jump that clears the gap during a burn reaches 984 in/min (25 m/min) at 1.6 G, and a fast jump is what carries debris out of deep, narrow cavities. Linear scales with 0.05 µm resolution are standard on X, Y and Z. The C-axis range is 1 to 30 rpm, an internal spindle running 1 to 1,500 rpm is optional, and the automatic tool changer option is the MVH-40.
A chiller is standard and the filter tank holds 124 gal (470 L) with two paper cartridge filters. Services are 200/220 VAC ±5% at 7 kVA with the FP80PS or 10 kVA with the FP120PS, plus 2.7 cu.ft./min of compressed air at 90-100 psi. The machine occupies 67.9 x 83.9 in (1,725 x 2,130 mm), stands 95.2 in (2,420 mm) high installed and weighs 7,716 lb (3,500 kg).

Strengths & Limitations
Strengths
- High-speed jump of 984 in/min (25 m/min) at 1.6 G for clearing debris from deep cavities
- Linear scales with 0.05 µm resolution are standard on X, Y and Z
- Three-sided drop tank with a 35.4 x 25.6 x 13.8 in (900 x 650 x 350 mm) maximum workpiece on a 27.6 x 19.7 in (700 x 500 mm) table
- Table load of 2,200 lb (1,000 kg) and electrodes up to 176 lb (80 kg) on the platen
- Dielectric chiller is standard
- Runs on 7 kVA with the standard FP80PS power supply
Limitations
- The 120 A FP120PS power supply is an option; the standard FP80PS is 80 A
- The internal spindle (1 to 1,500 rpm) and the MVH-40 automatic tool changer are options, not standard equipment
- Z travel is 11.8 in (300 mm) and table-to-platen distance tops out at 19.7 in (500 mm), which limits tall workpieces under long electrodes
- With a 3R Macro C-axis chuck the table-to-chuck distance is 7.2 to 19.0 in (183 to 483 mm), less than with EROWA ITS
- Needs compressed air, 2.7 cu.ft./min at 90-100 psi, in addition to 200/220 VAC power

01
X travel is 15.7 in (400 mm), Y travel is 11.8 in (300 mm) and Z travel is 11.8 in (300 mm). The table is 27.6 x 19.7 in (700 x 500 mm) and carries 2,200 lb (1,000 kg). The maximum workpiece is 35.4 x 25.6 x 13.8 in (900 x 650 x 350 mm), inside a three-sided drop tank that measures 37.0 x 27.5 x 17.7 in (950 x 700 x 450 mm) internally.
02
The standard supply is the FP80PS at 80 A, and the FP120PS at 120 A is an option. Electrical requirements are 200/220 VAC ±5%, at 7 kVA with the FP80PS or 10 kVA with the FP120PS.
03
Table to platen is 7.9 to 19.7 in (200 to 500 mm). With a C-axis chuck it is 7.9 to 19.7 in (200 to 500 mm) for EROWA ITS and 7.2 to 19.0 in (183 to 483 mm) for 3R Macro. Subtract the workpiece height and the electrode length from the upper figure to see what stroke is left for a given job.
04
A footprint of 67.9 x 83.9 in (1,725 x 2,130 mm), an installed height of 95.2 in (2,420 mm) and a machine weight of 7,716 lb (3,500 kg). It needs 200/220 VAC ±5% power, 7 kVA or 10 kVA depending on the power supply, and 2.7 cu.ft./min of compressed air at 90-100 psi. The filter tank capacity is 124 gal (470 L).
05
The SV12P is listed with the same 15.7 in (400 mm), 11.8 in (300 mm) and 11.8 in (300 mm) travels, the same 275.5 in/min rapid traverse and the same 7,716 lb (3,500 kg) weight. The control is the difference in the headline figures: an M700 Series CNC with a 15 in touchscreen on the EA12PS, and Mitsubishi Electric SV-CNC on the SV12P.
