As a result, the MEX15 supports reliable machining of tight-tolerance parts while maintaining efficient use of floor space in production and toolroom environments.
The Seibu MEX15 is a high-precision wire EDM built for demanding applications that require both flexibility and performance. Designed for ultra-precision machining, this CNC wire EDM system supports operations using both water and oil dielectric configurations. The MEX15 runs as a water wire EDM machine for general-purpose cutting. It also switches to oil dielectric wire EDM for superior surface finishes and tight tolerances, delivering consistent results across a variety of conductive materials.
This ultra-precision oil wire EDM setup enhances accuracy for micro-featured parts, medical components, and fine-detail tools. By reducing electrode wear and minimizing discharge gaps, the oil wire EDM machine configuration enables extremely fine cuts with minimal thermal impact. The water wire EDM machine mode delivers efficient material removal for standard high‑precision EDM applications. The MEX15 seamlessly supports both modes, giving manufacturers unmatched versatility without needing two separate systems.
With its rigid structure, thermal-stable design, and Seibu’s advanced CNC wire EDM system, the MEX15 ensures consistency over long jobs. The machine includes Seibu’s Smart NC control for simplified programming and real-time optimization of cutting conditions. Whether in water or oil mode, the MEX15 high precision wire EDM maintains clean finishes, sharp corners, and dimensional control. For shops requiring ultra-precision oil wire EDM or a high-performance water wire EDM machine in a single, compact platform, the MEX15 stands out as a flexible, capable solution.

The Seibu America MEX15 is a micro
wire edm for micro tooling, miniature medical parts, precision electrodes,
and fine-feature components. Its application is centered on micro-wire
cutting with water- or oil-dielectric configurations and wire sizes down to
0.03 mm, giving manufacturers a process option for components whose critical
profiles must be produced without direct cutting pressure from a conventional
tool. A.W. Miller Technical Sales supports EDM evaluation, process planning,
installation, training, and service for manufacturers throughout New York,
Pennsylvania, Maryland, Delaware, Southern New Jersey, and
Quebec.
Selecting the
MEX15 should begin with the actual geometry rather than travel alone.
Workpiece size and thickness, material, smallest internal radius, wire
diameter, taper requirements, surface-finish target, feature location
tolerances, dielectric strategy, threading access, and expected production
volume all influence the final EDM process. The machine configuration should
be checked against the complete part family and inspection plan before
purchase.
Parts and processes commonly evaluated for the Seibu America MEX15
include:
Very small wire
diameters support narrow kerfs, small radii, and intricate geometry that
conventional wire sizes cannot reproduce.
Water and oil specifications allow the process
to be selected around workpiece material, finish requirements, and
micro-machining priorities.
Wire size and dielectric choice affect corner
radius, flushing, cutting speed, recast behavior, and attainable finish.
Those variables should be established from the drawing and material rather
than selected independently.
Fine geometry requires a stable relationship
between wire guidance, threading strategy, skim cuts, and inspection. Process
development should account for the smallest slot or radius as well as the
surrounding feature locations.
Seibu lists wire capability down
to 0.03 mm for the MEX15. That makes the machine relevant to micro-EDM
applications where conventional wire diameters cannot produce the required
kerf, slot width, or internal radius.
Yes. The MEX15 is offered in
water- and oil-dielectric specifications. The choice should be based on
material, required finish, micro-feature stability, cutting conditions, and
the shop’s production priorities.
Examples include miniature
slots, very small internal radii, delicate profiles, micro tooling, and
closely spaced precision features. The deciding factor is whether the
geometry and tolerance require a wire size and process control beyond
conventional wire EDM work.
Micro wire places greater
emphasis on threading reliability, wire handling, flushing, workpiece
cleanliness, thermal stability, and cut-condition selection. Part programming
and inspection also need to reflect the much smaller feature scale.
Qualification should use
representative material and geometry, then verify feature size, location,
corner condition, finish, repeatability, and inspection capability. A
successful micro-EDM process depends on the complete chain from part
preparation through final measurement.
