New high-speed FP-V power supply

―③

•

Finishing performance and tungsten carbide machining performance equal

to the EA12V Advance

•

Optimized machining technology enables low-wear machining with graphite

electrode

•

FP120V power supply is suitable for high-speed rough machining of graphite (option)

High-rigidity and high-accuracy technology

―④

•

Machining stability is improved by increasing the machine structure's rigidity

• Mitsubishi Electric original thermal displacement compensation function

and semi-cabin structure are adopted

• Standard linear scale on Z-axis

• Machine temperature fluctuation suppressed to a minimum with fluid

circulation function

Advanced machining control

―⑥

•

Machine medium-to large-sized workpieces or deep ribs with advanced SS Jump 3

•

Adjustable high-volume fluid flow rates increase the range of no-flush machining

• Machining performance using graphite electrodes improved with GF2

control (option)

Greatly improve machining speed for rib shapes and electrode wear in

formed mold shapes

Outstanding operability

―⑤

• The three-sided drop tank improves access for work set-up (with working

tank multi-position function)

• Working tank fluid high-flow rate mode compatible with medium to large

graphite machining

• Standard high-function manual operation box with coordinate display

• Easy workpiece loading using hand lifter

• Machine zero point position at center of the XY-axes stroke corresponding

to medium to large electrodes

Outstanding operability

―①

• 15-inch LCD touch panel

• Easy-to-use menu configuration

• Machining conditions search (shape expert)

Utilizing CAD data

―②

• Machining instruction information (EPX) can be read from CAD/CAM

• 3D data (Parasolid) can be read in

• Area changes can be calculated from 3D model to optimize machining

conditions (3D-EXPERT)

(Note 1) For MACRO Jr of 3R-Combi and Compact of EROWA-COMBI, the weight is 2.5kg (5lb.) /electrode.

(Note 2) MACRO of 3R-Combi, the weight is 5kg (11lb.)/ electrode, and is 2.5kg (5lb.)/ electrode with

MACRO Jr. In both cases, the magazine total is 40kg (88lb.).

(Note 3) ATC can be used with EROWA ITS50, but not with EROWA Compact (manual only).

(Note 4) Tolerable electrode weight specifications of 10kg (22lb.)/ electrode (magazine total: 80kg (176lb.)) are also

available with the MVH40T-ATC.

(Note 5) Contact your local Mitsubishi Electric sales or dealer if the electrode exceeds the specified dimensions.

(Note 6) MVH40T-ATC, electrodes exceeding the specified dimensions cannot be mounted even if space is

provided in the magazine because there will be interference with the machine.
