How much does the Mitsubishi Electric EA28V Advance 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 EA28V Advance is a mid-size sinker EDM with 650 mm (25.6 in) of X travel, 450 mm (17.7 in) of Y and 350 mm (13.8 in) of Z over an 850 x 600 mm (33.5 x 23.6 in) table. The table is rated for 2000 kg (4409 lb) and the head for a 200 kg (441 lb) electrode, which places it with mold bases and die blocks, not small inserts.
The work envelope is larger than the table. Mitsubishi Electric gives maximum workpiece dimensions of 1050 x 760 x 350 mm (41.3 x 29.9 x 13.8 in), so a block can overhang the 850 x 600 mm table and still sit inside the 1100 x 810 x 450 mm (43.3 x 31.9 x 17.7 in) working tank. The tank is the automatic elevation type, and the fluid level adjusts from 100 to 400 mm (3.9 to 15.7 in) above the table top. Three T-slots, listed as 14-200mm pitch, hold the work.
Power comes from the FP80V-A supply with a maximum machining current peak of 80 A. The FP120V-A at 120 A is an option, worth specifying if large-area roughing with big electrodes is the plan. The control is the C31EA-2 Advance control unit with a 15-inch color TFT-LCD touch screen.
Loading height is 900 mm (35.4 in) from floor to table top. The complete system weighs 5400 kg (11905 lb) and occupies 2195 x 2512 x 2615 mm (86.4 x 98.9 x 103.0 in) in width, depth and height. Dielectric is held in a 390 L (103 gal) reservoir, with an initial fill of 595 L (157 gal), filtered through three fine paper filters and cooled by a unit cooler.

Strengths & Limitations
Strengths
- 2000 kg (4409 lb) table load and a 200 kg (441 lb) electrode limit on a machine with 650 x 450 x 350 mm (25.6 x 17.7 x 13.8 in) travels
- Maximum workpiece of 1050 x 760 x 350 mm (41.3 x 29.9 x 13.8 in), larger than the 850 x 600 mm (33.5 x 23.6 in) table
- Automatic elevation tank with fluid level adjustable from 100 to 400 mm (3.9 to 15.7 in) above the table
- FP80V-A power supply with an 80 A machining current peak, and the FP120V-A with 120 A available as an option
- C31EA-2 Advance control unit with a 15-inch color TFT-LCD touch screen
Limitations
- The 120 A FP120V-A power supply is an option; the listed supply is the 80 A FP80V-A
- Z travel and maximum workpiece height are both 350 mm (13.8 in), so check electrode length against block height on deep work
- The initial fill is 595 L (157 gal) of dielectric, more than the 390 L (103 gal) reservoir capacity, and has to be planned for at installation
- At 2615 mm (103.0 in) high and 5400 kg (11905 lb), it needs overhead clearance and a rigging plan checked in advance

Frequently Asked Questions
01
Up to 1050 x 760 x 350 mm (41.3 x 29.9 x 13.8 in) and 2000 kg (4409 lb). The table itself is 850 x 600 mm (33.5 x 23.6 in), and the working tank measures 1100 x 810 x 450 mm (43.3 x 31.9 x 17.7 in) inside, so the largest block overhangs the table. Axis travel is 650 x 450 x 350 mm (25.6 x 17.7 x 13.8 in).
02
Peak current. The FP80V-A is the listed power supply, with a maximum machining current peak of 80 A. The FP120V-A raises that to 120 A and is marked as an option, so it has to be ordered with the machine if high-current roughing is needed.
03
The dielectric reservoir capacity is 390 L (103 gal), and the initial dielectric fluid supply amount is 595 L (157 gal). The fluid is filtered by three fine paper filters and its temperature is controlled by a unit cooler.
04
The EA8PV Advance is the small machine with the same control: 300 x 250 x 250 mm travels, a 500 x 350 mm (19.7 x 13.8 in) table, a 550 kg (1213 lb) table load and a 2000 kg (4409 lb) total system weight. The EA28V Advance has 650 x 450 x 350 mm (25.6 x 17.7 x 13.8 in) travels, a 2000 kg (4409 lb) table load and weighs 5400 kg (11905 lb).
05
Machine dimensions are 2195 x 2512 x 2615 mm (86.4 x 98.9 x 103.0 in) as width, depth and height, and the total system weight is 5400 kg (11905 lb). The table top is 900 mm (35.4 in) above the floor, which is the height to plan crane or cart loading around.
