New jet water flow mechanism
●Flow analysis simulation was used to optimize the water
flow mechanism for straightening the jet stream, which
improves wire threading for thick workpieces
Wire electrode annealing structure
●Improved wire annealing power supply and tension control
enhance wire threading (producing a curl ratio of 10% or
less), which straightens the natural curl caused by
spooling
●The greatly lengthened distance of annealed wire
improves automatic wire threading for thick workpieces
*A curl ratio of less than 3% applied for the conventional model (FA Series)

Improved automatic wire threading
●New annealing system greatly improves wire threading
with a curl ratio of less than 10%
●Wire break point insertion is greatly improved for thick
workpieces
●Wire threading mode can be selected to match the
workpiece shape (i.e., jet stream on, jet stream off and
submerged break point insertion)
One-touch lever clamp mechanism
●New one-touch lever clamping system provides quick,
easy and accurate power feed indexing
●The clamp lever accurately locates the power feeder with
repeatable torque, unlike systems that use the set-screw
method
Diamond guide
●A round diamond guide is used to provide the best
accuracy for both straight and taper cutting applications
●Both upper and lower guides can be replaced by simply
unscrewing the flush cups
Wire collection unit
●Broken wire collection, which clears the upper guide after
a wire break, has been improved so it handles even highly
curled wire with no hesitation
Wire feed wiper
●A felt wiper added to the wire path removes manufacturing
impurities from the wire surface, which reduces slipping
on the drive rollers

* Air (compressed air) is used to operate the automatic wire feeder and work tank door, etc. Air
supplied from a normal compressor contains various impurities that could cause operation faults if
they get into the pneumatic devices such as the solenoid valve. Install an air filter with a drainage
discharge mechanism, etc., in the air source (primary source) piping to prevent impurities from
entering the pneumatic devices.
Machine Installation Checklist
Determining the machining details
Installation Conditions
1) Determine the workpiece
2) Determine the machining site
3) Determine the pre-processing site
4) Determine the post-processing site
Confirmation of foundation and power-supply work
If there is any possibility of radio disturbance, investigate it prior to starting work.
1) Confirmation of floor area
2)
Confirmation of environment (constant pressure, dust-proof room, measure for radio disturbance, prevention of external noise)
3) Confirmation of foundation floor
4) Foundation work
5) Primary wiring for power lead-in
6) Grounding work
7) Construction of dielectric fluid (city water) supply/drainage facilities
8) Air piping work
Confirmation of delivery path
1) Traffic restrictions to factory
Road width
Entry road
2) Factory entrance and width of gate in factory m
Factory building entrance dimensions (height × width) m × m
3) Constant-temperature, dust-proof room entrance dimensions (height × width) m × m
Preparation of installation fixtures
1) Plan the installation fixtures
2) Prepare or manufacture the fixtures
1) Select the programmers and operators
2) Apply for training seminars
Preparation of consumable parts
1) Purchase consumable parts such as wire electrodes
Training of programmers and operators
Cautions
The standard delivery entrance dimensions for standard shipment delivery are given on the product
introduction page. If the entrance is smaller than the standard delivery entrance, the machine shipped
may have different dimensions.
Contact a Mitsubishi Electric sales office for details (a separate estimate will be issued).
Note that delivery may not be possible in some cases depending on the dimensions.
Precautions for Selecting Earth Leakage Breaker
To prevent malfunctions caused by the external noise from control units, etc., a filter
is installed for the power-supply input. By grounding one end of this filter, an earth
leakage current of approx. 30mA to 40mA passes through the filter. A highly sensitive
earth leakage breaker (sensitivity current 30mA) could malfunction. Thus, a
medium-sensitivity earth leakage breaker (sensitivity current 100mA to 200mA) is
recommended for the EDM. Class C grounding (grounding resistance of 10Ωor less)
is recommended for the wire-cut EDM. Even if the sensitivity current is 200mA, the
contact voltage will be 2V or less, and no problems will occur in preventing electric
shock (application of tolerable contact current Class 2, 25V or less).
Harmonic Distortion
If there is harmonic distortion in the power supply, the machine operation could be
affected even if the voltage does not fluctuate. In addition, the harmonic current could
flow from the wire-cut EDM to the power system and adversely affect peripheral
devices. If the effect of the harmonic distortion causes problems, install a harmonic
suppression filter or take other measures.
Disposal
The dielectric fluid, dielectric fluid filter, ion exchange resin, wire, etc., are industrial
waste. These must be disposed of following national and local laws and ordinances.
1. Installation site
Constant-temperature, dust-proof room
·Recommended room temperature 20±1°C (68°F±2)
·Usable temperature range 5 to 35°C (44°F to 95°F)
Temperature fluctuation will directly affect machine accuracy. To maintain
performance accuracy, select a place with minimal temperature fluctuation.
Install the EDM in a constant-temperature room when performing high precision
machining, even when using skim cuts.
Note that an environment where the temperature fluctuates by 3°C (5°F) or more
within 24 hours, or 1°C (2°F) or more within one hour can adversely affect
machining accuracy. Make sure that the machine body is not subject to direct
wind from air-conditioners or to direct sunlight.
·Dust-free location is recommended.
Grinding dust can adversely affect the machine's linear scales and ball screws.
Pay special attention to installation location to avoid this hazard (separate from
grinding machine, or install in separate room, etc.).
·Humidity Within 30 to 75%RH (with no dew condensation).
·Temperature range during transportation and storage
-25 to 55°C (13°F to 131°F) (when power is not connected).
Tolerable vibration of floor
·Select an floor where vibration or impact will not be conveyed.
·As a reference, the vibration level should have a max. amplitude of 2µm or less at
a 10 to 20Hz frequency.
·Consult with the contractor or vibration measuring instrument maker for details on
the measuring method.
Foundation
·The floor should be concrete with a thickness of 400mm (15.7") or more so it can
sufficiently withstand the system’s weight.
·The floor inclination (step) must be within 6/1000 (floor inclination 6mm per 1m)
(MV2400 Series).
2. Machine heating
• Approx. 8,140W of heat is generated per machine, of which 1,512W is heat
generated by the dielectric fluid control unit.
• Take this into consideration when studying air-conditioning requirements.
3. Power-supply equipment
• Primary wiring 3-phase 200/220VAC±10% 50/60Hz±1Hz
• Power capacity
10.0kVA (during normal use) (when using Ø0.2(.008")mm wire electrode)
13.5kVA (when using the maximum)
* Use a 14mm2or thicker cable for the primary connection.
4. Grounding work
Wire-cut EDMs must always be grounded to prevent external noise, radio
disturbance and earth leakage.
Class C grounding (grounding resistance of 10Ωor less) as set forth in the
Electric Facility Standards is recommended for Mitsubishi Electric EDMs.
·Class C grounding (isolated) is recommended (Wire-cut EDM dedicated
grounding) (Fig. 1).
Note) Provide isolated grounding for each machine.
·Common grounding can be used if noise from other devices will not enter through
the common grounding; the grounding cable must be connected independently to
the grounding location (Fig. 2).
·Use a 14mm2grounding wire.
5. Primary air equipment
• Hose diameter : 1/4 hose (hose sleeve outer diameter: ø9.0 (0.35"))
• Pressure : 0.5 to 0.7MPa (70 to 100psi)
• Flow rate : 75L/min or more (26cu.ft./min.)
