How much does the Mitsubishi Electric EA28V-ADV 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
Mitsubishi Electric's EA28V-ADV is a die-sinking EDM with an FP80V-A power supply, 80 A of peak machining current and travels of 650 x 450 x 350 mm (25.6 x 17.7 x 13.8 in). It runs on the C31EA-2 Advance control unit, operated from a 15-inch color TFT-LCD touch screen. An FP120V-A supply rated at 120 A is offered as an option.
Planning the installation starts with three numbers: a total system weight of 5400 kg (11905 lb), a footprint 2195 mm (86.4 in) wide by 2512 mm (98.9 in) deep, and 2615 mm (103.0 in) of height. Then comes the oil. The reservoir holds 390 L (103 gal), but the initial dielectric fluid supply amount is 595 L (157 gal), so order to the larger figure. Filtration is by three fine paper filters and the fluid temperature is handled by a unit cooler.
For the operator, the table top sits 900 mm (35.4 in) off the floor and the working tank is an automatic elevation tank measuring 1100 x 810 x 450 mm (43.3 x 31.9 x 17.7 in) inside. Fluid level can be set anywhere from 100 to 400 mm (3.9 to 15.7 in) above the table. The 850 x 600 mm (33.5 x 23.6 in) table carries 2000 kg (4409 lb), the ram accepts electrodes up to 200 kg (441 lb), and the largest workpiece is 1050 x 760 x 350 mm (41.3 x 29.9 x 13.8 in).
Within the range it sits well above the EA8PV Advance, which has a 500 x 350 mm (19.7 x 13.8 in) table and a 550 kg (1213 lb) load limit. The EA28V Advance page lists the same travels, table size and system weight as this one.

Strengths & Limitations
Strengths
- Peak machining current of 80 A from the listed FP80V-A power supply, with a 120 A FP120V-A offered as an option
- Table rated at 2000 kg (4409 lb), against 550 kg (1213 lb) on the EA8PV Advance
- Working tank of 1100 x 810 x 450 mm (43.3 x 31.9 x 17.7 in) inside, of the automatic elevation type
- Dielectric is cleaned by three fine paper filters and cooled by a unit cooler
- Electrodes up to 200 kg (441 lb) can be mounted
Limitations
- Travels of 650 x 450 mm (25.6 x 17.7 in) cover only part of the 1050 x 760 mm (41.3 x 29.9 in) maximum workpiece, so cavities near the edges of a full-size block may be out of reach
- The table has three T-slots, listed as 14-200mm pitch, which limits clamping positions for small fixtures
- Fluid level stops at 400 mm (15.7 in) above the table, which caps the height of a submerged setup
- The catalog table states no positioning accuracy, rapid rate or surface finish figure for this model

Frequently Asked Questions
01
The figures match. The EA28V Advance page lists the same 650 x 450 x 350 mm (25.6 x 17.7 x 13.8 in) travels, 850 x 600 mm (33.5 x 23.6 in) table, 2000 kg (4409 lb) table load, 5400 kg (11905 lb) system weight and C31EA-2 control as the EA28V-ADV.
02
The table names the FP80V-A, with a maximum machining current peak of 80 A. A second unit, the FP120V-A at 120 A, is marked as optional. Ask which one is on the quotation, because the choice sets how much current is available for roughing large electrode areas.
03
Allow 2195 mm (86.4 in) of width, 2512 mm (98.9 in) of depth and 2615 mm (103.0 in) of height for the machine, and a floor that carries the 5400 kg (11905 lb) total system weight. Work is loaded onto a table 900 mm (35.4 in) above floor level.
04
Two volumes are given. Reservoir capacity is 390 L (103 gal). The initial dielectric fluid supply amount is 595 L (157 gal), so the first delivery of fluid should be planned around the larger number, not the reservoir figure.
05
The 850 x 600 mm (33.5 x 23.6 in) table has three T-slots, which the catalog lists as 14-200mm pitch. Blocks up to 1050 x 760 x 350 mm (41.3 x 29.9 x 13.8 in) and 2000 kg (4409 lb) are allowed, so large work overhangs the table inside the tank.
