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.
