Next-Level machines. Better Business.
The new generation of wire EDM.
More precise, more stable and easier to operate: the MG-R series from Mitsubishi Electric takes your wire EDM to the next level — at lower total cost of ownership.
Product introduction
A new level: the MG-R models
The MG24R and its compact sister MG12R: further developments based on the proven MV series, focusing on precision, stability and ease of operation.
MG12R
- Travel 400 / 300 / 220 mm — compact production footprint
- Workpiece weight up to 500 kg
- Reproducible results, a machine that keeps producing
MG24R
- Travel 600 / 400 / 310 mm — for large, heavy workpieces
- Workpiece weight up to 1,500 kg
- Micrometre precision with wire diameters from 0.1–0.3 mm
Why MG-R
Six reasons
that make the difference
Intelligent Auto-Threading
Automatically re-threads at any position after a wire break – without returning to the start position. Enables autonomous 24/7 operation.
Optical Drive System
Contact-free tubular direct drive – no wear, no cogging. 15-year manufacturer’s warranty on positioning accuracy.
Thermal Control System
Synchronised temperature control of machine body and dielectric keeps precision constant even during long runtimes.
Intuitive control
Multi-touch display, dialogue guidance and launcher make operation as easy as on your own PC, even with up to eight axes.
Maisart (AI)
Thanks to Mitsubishi Electric’s AI, wire EDM is easier than ever. With its help we have improved our technology even further.
Fast ROI
High reliability ensures low operating costs. Low material consumption and low energy costs add up to a fast ROI.
Functions & construction
All functions at a glance
From AI to drives to control: this is how the MG-R is engineered to keep processes stable and reduce downtime.
Intelligent Auto-Threading
Automatically re-threads the wire at any position after a wire break.
Optical Drive System
Contact-free tubular direct drive — 15-year warranty on positioning accuracy.
Thermal Control System
Synchronised temperature control, repeat accuracy of 3 µm on the X/Y axis.
Crash Protection System
Automatically detects obstacles during approach and prevents collisions.
Control (D-CUBES)
Large multi-touch screen with launcher for shortcuts and step-by-step dialogue guidance.
Scheduler
Prioritise, interrupt and resume jobs — without programming effort.
Maintenance and process management
Consumables and processes at a glance, for planning and cost analysis.
EDM-PiLOT / XEDM / XpressCAM
3D programming without lengthy training — sometimes one click to the NC program.
Ultra Finish Surface
Particularly fine, homogeneous surfaces down to Ra 0.13 µm — less post-processing.
For demanding industries
Taper cuts, smallest radii and hard or hardened materials are no problem.
Corehold technology
Remove many slugs in one operation — ideal for unattended night runs.
Convenient access to the tank
Particularly convenient access to the work tank — easier cleaning, faster back to work.
Ergonomic machine concept
All controls within reach at the front, automatic vertical sliding door.
Easy maintenance
Wire change in 90, filter change in 30, power feed contact change in 5 seconds.
Maisart (artificial intelligence)
Mitsubishi’s own AI supports processes and ensures consistently high precision.

Profitability
Rather profitable
Machines that run without disruptions and require little maintenance reduce time and costs for every workpiece. The bottom line: lower total cost of ownership and higher profitability.
Comparatively low acquisition costs
Low material consumption & low energy costs
High productivity thanks to reduced downtime

Automation
Plug & play for your EDM production
With the Cube Cell and the Produ Cell / Diamond Cell, Mitsubishi Electric offers ready-made automation products, designed specifically for EDM machines. Instead of planning an individual project solution from scratch, you receive a coordinated system of EDM machine, robot and integrated cell software — developed from a single source.
Run your EDM production autonomously for up to 80 hours – including over the weekend. This increases machine runtime, raises your output and creates a tangible competitive advantage.
Plug & play instead of project solution
Quickly installed and commissioned — no individual project engineering required.
Developed specifically for EDM
Machine, robot and process are matched exactly to the requirements of wire EDM.
Integrated cell software
Already geared to the EDM application, part of the overall system.
Budget-friendly investment
The standardised solution reduces planning and integration effort compared to individual projects.
Up to 80 hours of autonomous runtime
Automated operation, including overnight and over the weekend.
Precision in detail
Precision opens up new possibilities
Taper cuts with different contours on top and bottom, smallest radii and the machining of extremely hard or already hardened materials are no problem for the MG-R.
These industries also rely on us:
