Interface step difference
The SPG machining circuit (standard specification) delivers a best surface finish of Rz 0.25 μm for tungsten carbide and Rz 0.3
μm for Tool steel (SKD11). Such surface finishes are unobtainable in grinding operations, but the EDAC1 provides this superior
performance even for finish machining of tiny 3-D shapes. The result is uniform machined surfaces of high quality that shorten
the polishing process. The machining of tungsten carbide requires the carbide machining circuit (optional equipment).
Interface step difference of less than ±1 mInterface step differences of less than ±1 μm are obtained between ground and EDMed surfaces and also between two
EDMed surfaces. Stable accuracy in the depth minimizes step differences at interfaces where overcutting is not allowed in
the final machining process. This works to shorten the finishing process substantially.

Corner radius as tiny as 5 μmEver-smaller connector pins are being used in mobile phones, PCs and other devices as these products become
increasingly thinner and more sophisticated. As a result, there is a greater need to execute tiny inside corner radius
in the dies/molds used for manufacturing connectors. The EDAC1 can accurately machine corner radius as tiny as 5 μm
in connector dies/molds.

Machining accuracy to within ±2 μm in continuous operation using an ATCThe EDAC1 is built to minimize thermal distortion, enabling it to deliver superior accuracy even over long hours of
continuous machining. Machining accuracy to within ±2 μm is obtained in continuous operation using an ATC.
Stable depth accuracy
The sample shown below was milled or EDMed in the respective areas following grinding. All the interface step differences between the EDMed and the work mill surfaces were within ±2 μm of the ground reference surface.
Super Surface Gr. (standard specification)
A graphite electrode delivers a surface finish of Rz 1 μm,
which was previously regarded as the range of surface quality
obtainable only with a copper electrode.
Using a graphite electrode facilitates burr-free
manufacturing of electrodes in less time
compared with a metalcutting process. This
enables a quicker supply of electrodes for
markedly shorter delivery lead times.

The EDAC1 is designed with an axis layout free of
overhangs and with a short distance between the
machining point and each axis guide. This
construction minimizes attitude changes and enables
the spindle to provide the same superb accuracy
regardless of its position. The manufacturing tolerance
for axis straightness is 2 μm, but the actual values are
substantially less than that.
Thermal stability
Covers are placed over all the cast-iron machine components
to protect them from ambient temperature changes. The
machining generator and dielectric fluid cooling unit are
positioned at the rear of the machine, and exhaust air ducts
are provided between these heat sources and the machine
proper. This prevents heat from being transferred to the
machine. Insulation is also provided at the rear and under the
machine. Makino's Thermal Guard cover the Z-axis and the
work tank, thereby suppressing the effects of ambient
temperature changes.

Z-axis stabilizer (standard specification)
Heat generated by repeated jump motions in the Z-axis can
cause accuracy in the depth direction to become unstable.
This can result in product defects when machining
workpieces requiring high accuracy. The Z-axis stabilizer
effectively removes such heat by circulating temperature-
controlled dielectric fluid through the core of the ball screws
and to the ball nuts. This works to improve machining depth
accuracy dramatically.
Thermal Chamber (optional specification)
The Thermal Guard fully encloses the entire machine in covers to
prevent attitude changes by suppressing thermal distortion due
to sharp ambient temperature variation.
Thermal Guard (optional specification)
Pin gate machining Machining depth error causes the hole diameter at the gate tip to vary.
The EDAC1 is fitted with the Z-axis stabilizer as a standard feature to provide stable machining depth accuracy.

Air controlled to a precise temperature is circulated throughout the entire
interior of the machine to keep the temperature inside the splash guard
within a range of ±0.5°C. Creating this small thermal chamber inside the
splash guard facilitates stable, high-accuracy machining. Because it
eliminates the need to maintain a constant temperature in the entire shop,
it contributes to energy savings by avoiding wasteful energy
consumption.

Easy operation
Height-adjustable control panel
Easy maintenance
The compressed air unit, dielectric fluid filtration system,
fire extinguisher and other units requiring regular
inspection are all concentrated near the right side of the
machine to facilitate efficient maintenance work.
Drop tankThe dielectric fluid height can be set to match the workpiece thickness, making it easy for the operator to check the machining condition.
Accessibility
Makino's drop tank design provides
open access to the workpiece and the
table from three sides, enabling work
to be done more efficiently. The table
is also positioned at a convenient
height of 1,000 mm from the floor to
allow a comfortable working posture.
Standard features on the EDAC1 include a large 15 inches
liquid crystal display screen for operations, touch panel,
portable control panel and an Ether port. Moreover, the
height of the control panel screen is adjustable to four
levels in increments of 30 mm, enabling it to be set to
match the operator's
height.

Total Support System
This software for generating electrode models is
installed in Makino's FF/eye 3-D CAD/CAM
system. An electrode model can be generated in
just one minute by simply selecting the portions
of the die/mold model to be EDMed. An electrode
machining program can be generated easily from
the electrode model using FF/eye.
Data on electrode EDM positions, shapes and
amount of dimension reduction are output in the
EPX format to EDM.

Electrode generation support tool
EZ electrode modeling Generates electrode models from CAD data
Operators have so far manually input the EDM
positions of each electrode while looking at a
work instruction sheet. Over 50% of EDM errors,
however, are reportedly caused by incorrect entry
of machining positions.
This means that mistakes in the final EDM
process can result in large losses. EDcam
imports machining position data in the EPX
format and generates a machining program
automatically, thereby eliminating the need for dry
runs.
CAM System for NC EDM machine
Enables electrode machining programs to be generated entirely on a PC
This system can be connected to as many as
three EDM machines and one pre-setter. (Or
measuring instrument) It substantially improves
machine uptime by enabling one operator to
supervise a cell of EDM machines and by
supporting off-machine setups. Machining
schedule changes are easy to make, and
machining can begin even if all the electrodes
are not ready yet.
Mold machining support tool
Generates EDM schedules and facilitates off-machine setups
・Function for generating machining schedules Machining schedules can be generated for individual workpieces and electrodes. Changes additions and deletions can easily be made to a machining schedule if rush jobs or interruptions occur while the schedule is being executed.・Function for managing electrodes This function is used to manage the status of electrodes, offset values, the number of times electrodes have been used and other information, not only for electrodes on the machine but also for those waiting to be set up.
This program incorporates a variety of handy functions for setting the electrode extension, orbit motion patterns, electrode dimension reduction, reference plane used for centering and other parameters. These functions greatly simplify the troublesome tasks involved in making electrodes.
・Function for managing workpieces This function manages the offset values of workpieces and machining programs and the electrode to be used.・Monitoring function This function enables the operator to know at a glance the progress of a machining schedule and the status of electrodes and workpieces waiting to be machined.
