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 EA12 Advance is a mid-size sinker EDM built around 600 mm (23.6 in) of X travel, 400 mm (15.75 in) of Y and 350 mm (13.8 in) of Z, and the listed figures let it carry a 1,000 kg (2,205 lb) workpiece. It is not part of Mitsubishi Electric's current lineup. Treat the listed figures as a starting point when inspecting a used machine, not as a confirmed specification.

What stands out is mass. At 7,500 kg (16,535 lb) and 2,100 x 2,800 x 2,600 mm (82.7 x 110 x 102 in), this is a heavy machine for its stroke, and the floor loading and the rigging route both need checking before a purchase. For comparison, the EA28V Advance has 650 mm (25.6 in) of X and 450 mm (17.7 in) of Y at a 5400 kg (11905 lb) total system weight.

Electrode-to-table clearance is listed as 150 to 500 mm (5.9 to 19.7 in), which leaves room for deep cavities and long rib electrodes that a 350 mm Z stroke alone would not suggest. The control is a Mitsubishi M800S CNC with multi-axis orbit programming, and the generator is the FP80 AI pulse generator with Miracle Circuit. Listed finish is VDI 3 / Ra 0.08 µm achievable, with electrode wear described as near-zero on graphite.

Connectivity is listed as Ethernet, remote monitoring and an Industry 4.0 interface. Before counting on that for unattended reporting, confirm what the machine in front of you is actually fitted with.

Strengths & Limitations

Strengths

600 x 400 x 350 mm (23.6 x 15.75 x 13.8 in) of listed travel with a 1,000 kg (2,205 lb) workpiece limit
Electrode-to-table clearance of 150 to 500 mm (5.9 to 19.7 in) leaves room for long electrodes over deep cavities
Mitsubishi M800S CNC with multi-axis orbit programming is the listed control
FP80 AI pulse generator with Miracle Circuit; listed electrode wear is near-zero on graphite
Drive system is listed as ball screws with linear scales

Limitations

At 7,500 kg (16,535 lb) it is heavier than the EA28V Advance, which is 5400 kg (11905 lb) total system weight with longer X and Y travel
The EA28V Advance takes a 2000 kg (4409 lb) table load, twice the 1,000 kg (2,205 lb) workpiece weight listed here
No electrode weight limit, tool changer or dielectric capacity appears in the listed figures

Best For

Mid-size mold cavities within 600 x 400 mm (23.6 x 15.75 in) of X-Y travel Deep ribs and long electrodes, using up to 500 mm (19.7 in) of electrode-to-table clearance Orbiting cuts programmed with the M800S multi-axis orbit function Workpieces up to 1,000 kg (2,205 lb)

Frequently Asked Questions

01 How big a job does the EA12 Advance handle?

The listed travels are 600 mm (23.6 in) in X, 400 mm (15.75 in) in Y and 350 mm (13.8 in) in Z, and the workpiece limit is 1,000 kg (2,205 lb). Height is governed by the electrode-to-table clearance of 150 to 500 mm (5.9 to 19.7 in), which has to cover the block, the electrode and its holder together.

02 How does the EA12 Advance compare with the EA28V Advance?

The EA28V Advance has slightly longer strokes, 650 mm (25.6 in) in X and 450 mm (17.7 in) in Y on the same 350 mm (13.8 in) of Z, with a 2000 kg (4409 lb) table load and a 5400 kg (11905 lb) total system weight. The EA12 Advance figures are 600 x 400 x 350 mm, 1,000 kg (2,205 lb) and 7,500 kg (16,535 lb), and its control is listed as the M800S where the EA28V Advance uses the C31EA-2 Advance control unit.

03 What control and generator does the EA12 Advance have?

The listed control is a Mitsubishi M800S CNC with multi-axis orbit programming. The generator is the FP80 AI pulse generator with Miracle Circuit, for which the table gives VDI 3 / Ra 0.08 µm as an achievable finish and near-zero electrode wear on graphite. Both are best-case statements and worth proving with a test burn.

04 What should be checked before moving an EA12 Advance into a shop?

Weight and size first. The machine is listed at 7,500 kg (16,535 lb) and 2,100 x 2,800 x 2,600 mm (82.7 x 110 x 102 in), so confirm floor capacity, door openings and crane or forklift capacity along the whole route. The listed figures do not state dielectric volume or electrical supply, so get both from the machine's own plate.
