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 SV12P is a sinker EDM with 15.7 in (400 mm) of X travel and 11.8 in (300 mm) each of Y and Z. Those strokes are modest, yet the machine accepts a workpiece of 35.4 × 25.6 × 13.8 in (900 × 650 × 350 mm) weighing up to 2,200 lb (1,000 kg), so it suits a shop that burns small cavities into fairly large blocks.

The table measures 27.5 × 19.7 in (700 × 500 mm) inside a work tank of 37.4 × 27.5 × 17.7 in (950 × 700 × 450 mm). Table-to-platen distance is 7.9–19.7 in (200–500 mm), which sets the combined height of workpiece, electrode and holder. Electrode weight is limited to 176.5 lb (80 kg). That is the figure to watch on this model: a big graphite electrode with its chuck can reach it long before the table limit matters.

Mitsubishi Electric lists the generator as the GV80P at 80 A, with the GV120P at 120 A shown in brackets as the alternative, so confirm which one a quoted machine carries. Axis rapid traverse is 275.5 in/min (7.0 m/min). The control is listed as Mitsubishi Electric SV-CNC.

Dielectric capacity is 124 gal (470 L). The footprint is 110.6 × 122.0 in (2,810 × 3,100 mm), the height 93.7 in (2,380 mm) and the weight 7,716 lb (3,500 kg). The EA12PS shares the 15.7 in (400 mm) X travel and the 7,716 lb (3,500 kg) weight but is listed with an M700 Series CNC control with 15 in touchscreen.

Strengths & Limitations

Strengths

Takes workpieces up to 35.4 × 25.6 × 13.8 in (900 × 650 × 350 mm) and 2,200 lb (1,000 kg) on a 7,716 lb (3,500 kg) machine
Table-to-platen range of 7.9–19.7 in (200–500 mm) for tall setups
Rapid traverse of 275.5 in/min (7.0 m/min)
Generator listed as the GV80P at 80 A, with the GV120P at 120 A as the bracketed alternative

Limitations

Electrode weight is capped at 176.5 lb (80 kg), well under the 200 kg (441 lb) of the EA28V Advance
X travel of 15.7 in (400 mm) covers less than half of the 35.4 in (900 mm) maximum workpiece width, so cavities must sit near the middle of a full-size block
The 120 A GV120P appears in brackets, not as the first-listed generator; confirm what a given machine has
The table gives no positioning accuracy or surface finish figure

Best For

Cavities within 15.7 × 11.8 in (400 × 300 mm) in blocks up to 2,200 lb (1,000 kg) Electrodes up to 176.5 lb (80 kg) Setups that need up to 19.7 in (500 mm) between table and platen Multi-cavity work where 275.5 in/min (7.0 m/min) rapids shorten moves between positions

Frequently Asked Questions

01 What size workpiece does the SV12P accept?

Up to 35.4 × 25.6 × 13.8 in (900 × 650 × 350 mm) and 2,200 lb (1,000 kg). The table is 27.5 × 19.7 in (700 × 500 mm) and the work tank 37.4 × 27.5 × 17.7 in (950 × 700 × 450 mm). Travel is 15.7 in (400 mm) in X and 11.8 in (300 mm) in Y and Z, so the reachable area is smaller than the largest block.

02 Which generator does the SV12P have?

The table reads GV80P / 80 AMPs (GV120P / 120 AMPs). In other words the GV80P is the 80 A unit and the GV120P the 120 A unit, the latter given in brackets. The table does not say more about how the second is supplied, so check the quotation.

03 How heavy an electrode can the SV12P carry?

The maximum electrode weight is 176.5 lb (80 kg). Include the holder and chuck in that total. With 7.9–19.7 in (200–500 mm) between table and platen there is room for long electrodes, so weight, not height, is usually the limit to check first.

04 How does the SV12P compare with the EA12PS?

On the main figures they match: the EA12PS also has 15.7 in (400 mm) of X travel, 11.8 in (300 mm) of Y and Z, a 2,200 lb (1,000 kg) table load, 275.5 in/min (7 m/min) rapids and a 7,716 lb (3,500 kg) weight. The control differs. The EA12PS is listed with an M700 Series CNC control with 15 in touchscreen, the SV12P with Mitsubishi Electric SV-CNC.

05 How much floor space does the SV12P need?

The footprint is 110.6 × 122.0 in (2,810 × 3,100 mm) and the machine is 93.7 in (2,380 mm) high. It weighs 7,716 lb (3,500 kg), and the dielectric system holds 124 gal (470 L), which adds to the floor load once filled.
