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 EA8PV is listed here as a sinker EDM with 400 x 300 x 300 mm of X, Y and Z travel, an 800 x 600 x 420 mm work tank and an 800 kg (1,760 lb) workpiece limit. The model is not in Mitsubishi Electric's current lineup. The listed figures are also larger throughout than those of the EA8PV Advance, which has travels of 300 mm (11.8 in), 250 mm (9.8 in) and 250 mm (9.8 in) and a 550 kg (1213 lb.) table load, so confirm the envelope on any machine offered under this name.

The generator is listed at 35 A peak discharge current with ADVANCE pulse control, a modest current that suits small electrodes and finishing more than heavy roughing. Finish is given as under 0.2 µm Ra with finish electrodes. The dielectric system is hydrocarbon oil with programmable suction and injection flushing, the control is a Mitsubishi Electric M700VS CNC with touch HMI, and the machine weighs approx. 3,200 kg (7,055 lb).

Specifications compiled from manufacturer literature and industry references. Not independently verified against a published spec sheet — confirm with the manufacturer or an authorised dealer before making a purchasing decision.

Strengths & Limitations

Strengths

Programmable suction and injection flushing is part of the listed dielectric system
Surface finish listed below 0.2 µm Ra with finish electrodes
800 kg (1,760 lb) workpiece limit in an 800 x 600 x 420 mm work tank

Limitations

Peak discharge current is listed at 35 A, which limits the roughing rate with large electrodes
No electrode weight, table size or electrode changer is listed

Best For

Small cavities and detail work at up to 35 A Fine finishing below 0.2 µm Ra with finish electrodes Workpieces up to 800 kg (1,760 lb)

Frequently Asked Questions

01 How does the EA8PV differ from the EA8PV Advance?

On the listed figures the EA8PV has 400 x 300 x 300 mm of travel, an 800 kg (1,760 lb) workpiece limit and weighs approx. 3,200 kg (7,055 lb). The EA8PV Advance has travels of 300 mm (11.8 in), 250 mm (9.8 in) and 250 mm (9.8 in), a 500 x 350 mm (19.7 x 13.8 in) table, a 550 kg (1213 lb.) table load and a total system weight of 2000 kg (4409 lb.). The gap is wide enough that the machine itself should be measured.

02 What generator and control does the EA8PV have?

The generator is listed at 35 A peak discharge current with ADVANCE pulse control, and the control as a Mitsubishi Electric M700VS CNC with touch HMI. The dielectric is hydrocarbon oil, with suction and injection flushing that can be programmed.
