Mechanical Engineering
Solid Precise Easy to maintain
The compelling machine concept
Compact, robust mechanical engineering based on cast steel. No other material can better guarantee
the solidity and stability you need in order to benefit from your investment in the long term.
Best mechanical engineering: Made in Japan!
The high-resolution, digitally controlled direct drives (0.1 μm resolution), combined with generously
dimensioned spindles, ensure highest precision over the entire lifetime of the machine.
The dual measuring system with additional linear scales for the X, Y and Z axis work in closed
loop and ensures long-lasting precision.
Because precision needs perfection!
Classic cast steel machine design
with high-quality components
The Long-Life filters, exchangeable during
operation, as well as the central lubrication
system, offer you optimum maintainability.
Good access keeps unproductive times as
short as possible.

The Advance CNC Control
Touchscreen User-friendly Fast
The new Advance CNC control - the new standard in spark erosion
The new ADVANCE control based on the MITSUBISHI CNC M700 is captivating due to its user-friendliness
and reliability. In spite of its complex range of functions, it can be operated intuitively via control based on
Windows XP. The logical menu structure and uncomplicated design allow you to quickly and reliably
achieve your goal.
The control is performed via a sturdy 15" touch screen monitor, fixed function keys for commands most often
used, as well as via keyboard and mouse. The control can be linked to a network by way of the standard
Ethernet interface.
Professional work can be that easy!

Programming By Dialog
Simple
Comfortable
Dialog-based programming, making everything easi er for you
The processing program is created with the E.S.P.E.R. Advance software.
With this, the user is supported by clearly understandable and intuitive set-up cycles
as well as by a dialog-based function selection. With only a few basic parameters,
even inexperienced users quickly find an optimal eroding strategy and work successfully.
The operators of our wire eroding machines will highly appreciate the consistency
of the control systems; they already know the ropes!
The program is created in "Shape Expert".
Here, different basic shapes and specifications are used.
Programming is fast and easy.
The optimum processing technology is created automatically.

3-D Graphic Functions
Optimised Helpful Safe
Advance – Directly utilize your 3D CAD Data
The Advance Control also includes a 3D as well as 2D CAM system. 3D data in Parasolid format
as well as DXF or IGES files can be directly imported and converted to NC programs.
The shape of workpiece and electrode can be analyzed immediately after the import. This easily
understandable verification gives you additional safety before the start.
Make your daily work easier!
3D Expert
A new function of the E.S.P.E.R. Advance Control allows automatic adaptation
of the generator settings to the geometry of the workpiece to be processed.
This function can also be used if only 2D data are available, however optimal
results are produced nevertheless.
3D simulation of the machining
Subsequent to the creation of the
programs, a simulated processing
in 3D can be performed.

Processing Examples
Tungsten Carbide Steel Titanium
The formula of success for your productivity
Mitsubishi Electric's newly developed FP-V generator series is the new standard in
spark erosion. The combination of reduced electrode wear and high removal rates,
coupled with higher precision and the best possible surface quality, is sure to increase
your options.
For tungsten carbide machining, the EA-V Advance is the best reference, in particular
for small cavities and finest surfaces.
FP-V generator
The EA-V Advance models ensure the smallest
edge zone impact on the work piece for
increased durability of the work piece as
a whole (upper picture: for comparison -
the result of a spark erosion plant using a
conventional generator).
Conventional generator
Tungsten carbide machining
Surface quality Ra 0.15 μm
Workpiece: Tungsten carbide
Electrode: Tungsten copper
Helical gear machining
Function: integrated C axis
Material: Tungsten carbide
Electrode: Tungsten copper
Surface quality: Ra 0.3 μm
Ultra-precise helical gear machining is possible as a result
of the extremely rigid and integrated C axis.
The E.S.P.E.R. Advance programming function allows easy
programming of helical gear machining.
Titanium machining
The BMW Sauber F1 Team machines
titanium workpieces with graphite
electrodes (suspension arms for Formula 1).
Difficult flushing conditions, large section,
ideal for the FP120V generator
Material: Steel
Surface quality: Ra 1,6 μm
Depth: 130 mm
Electrode: Graphite
The EA-V Advance delivers stable eroding processes, even under
the most difficult flushing conditions. Additional contours are eroded
into the pre-milled workpiece, and the entire surface is finished to
the required surface quality (machining without additional flushing).

Processing Examples
Economical Flexible Future-safe
Manufacture a piece of the future
Do you manufacture compound tools, plastic mouldings, gearwheel moulds, profiles, prototypes
and many more things? And you think that highest productivity, flexibility and precision are
most important? Then you need the Mitsubishi Electric EA-V Advance series models, with
their unlimited scope of applications.
The obtained results will give you competitive advantages and economical success.
The "Fuzzy Control" function adapts the machining parameters during the eroding process,
optimising these automatically. This delivers stable and optimum machining speeds with
maximum performance.
Medical technology
Workpiece: Chrome-cobalt alloy
Electrode: Graphite
Mirror Finish machining
Function: GM circuit
Material: Steel
Electrode: Copper
Surface quality: Ra 0.06 μm
The GM circuit reduces the total polishing
cost drastically, or even down to zero.
This function is particularly suited for moulds
that are difficult to polish.
Multi-Rib machining
The E.S.P.E.R. rib function delivers a stable
eroding process with minimum electrode
wear, even for the finest rib electrodes.
The new graphite adapter minimises electrode wear
for graphite electrodes and ensures faster,
more stable processing of ribs and bars.

Automation
Handling Systems Manufacturing Cells Integration
You decide how much profit your machine produces
Certainly you want to increase the operating efficiency of your machine.
We offer several possibilities to reduce down-time. A 20 position tool changer
already makes a big difference but what about handling workpieces as well?
The highly flexible workpiece and tool handling device MER combines the professional
experience of the two market leaders Mitsubishi Electric and Erowa.
Storage space for up to 48 ITS 50 electrode holders or 6 UPS workpiece pallets, or any combination
of the two, guarantees fully used night and weekend shifts. And that’s where the profit lies, in the
autonomous operation of the EDM machine and the robot.
Workpiece pallets up to 80kg and electrodes of 20kg are handled absolutely automatically.
The available integrated chip reader system ensures absolute control. Together with
the cell management software “Master Cell Light” your operators will be on top
of things at any time.
Still not flexible enough? We also offer individual turn key solutions in close
co-operation with all leading automation suppliers.

processes had already begun in the early 1950's. Since 1963, Mitsubishi Electric has been manufacturing
erosion systems in serial production. Since that time over 54,000 erosion systems have
been installed for clients world-wide (as of 2009) – and this number increases every day!
We offer you a unique combination of the security provided by a world-wide, large-volume industry
leader and producer of erosion systems together with individual support services.
