Overview
The Mitsubishi Electric MV2400R is a precision wire EDM with 400 x 300 mm X/Y travel designed for mid-size toolmaking applications in mold, die, and precision component production. The 'R' designation in the MV2400R denotes the machine's rotary table configuration — the MV2400R incorporates an integrated B-axis rotary table as a standard feature, enabling 4-axis wire EDM with continuous workpiece rotation. This distinguishes it from the standard Mitsubishi MV2400S and makes the MV2400R specifically suited to cylindrical and prismatic component applications where wire EDM must be performed on multiple faces or at varying orientations without manual workpiece re-clamping.
The MV2400R is built on Mitsubishi Electric's Digital AE generator platform — the same generator architecture used across the full MV series. The Digital AE generator delivers precise discharge energy control with nanosecond pulse resolution, enabling surface finishes to Ra 0.18 um on standard steel and carbide workpieces. Positioning accuracy is ±0.001 mm on both the X/Y travel axes and the B-axis rotary table, achieved through Mitsubishi's thermal displacement compensation system and precision ball-screw drives with linear scales for closed-loop position feedback.
The B-axis rotary table on the MV2400R enables applications that are not practical on conventional 4-axis (X/Y/U/V) wire EDMs — including turbine blade root profile EDM, fuel injection nozzle orifice cutting, medical implant feature cutting on cylindrical components, and watchmaking component cutting on small cylindrical blanks. The table's index resolution and the MV2400R's control system allow the wire path to be synchronized with table rotation for helical cuts and multi-face profile cutting in a single program cycle.
The MV2400R uses Mitsubishi Electric's ADVANCE controller with the full technology table library for standard and exotic workpiece materials. Automatic wire threading with Mitsubishi's pipe-style threader (robust re-threading in partially cut workpieces) is standard. The MV2400R competes in a specialized segment of the wire EDM market where rotary capability is the primary selection criterion, with limited direct competition from machines specifically integrating a rotary table as a standard feature at this travel class.

Strengths & Limitations
Strengths
- Integrated B-axis rotary table as standard equipment enables 4+1 axis wire EDM for cylindrical component machining — turbine blade roots, fuel injector orifices, and medical implant features without manual re-clamping
- Digital AE generator with ±0.001 mm positioning accuracy across all axes including B axis enables the same precision standard on rotary work as on conventional planar cuts
- Ra 0.18 um surface finish on rotary-EDM'd surfaces matches the capability on X/Y planar cuts — consistent finish quality across all orientations
- Mitsubishi pipe-style threader provides robust automatic wire threading on partially cut and re-entry situations common in multi-face rotary EDM programs
Limitations
- B-axis rotary table reduces available table work area for conventional flat-workpiece EDM compared to the standard MV2400S — shops primarily doing planar EDM with occasional rotary work may find the table geometry awkward
- Programming complexity for B-axis synchronized wire EDM is significantly higher than for conventional X/Y/U/V work — requires specialized CAM software support or manual G-code programming for non-trivial rotary programs
- Premium pricing over the standard MV2400S — the rotary table integration adds meaningful cost that is only justified for shops with regular cylindrical component requirements

Frequently Asked Questions
01
The B-axis rotary table mounts the workpiece and rotates it under CNC control, synchronized with the X/Y wire positioning. For index-and-cut operations (most common), the B axis positions the workpiece to a specific angular orientation, locks, and the wire cuts the programmed profile. For continuous rotary cutting (helical cuts, gear tooth forms), the B axis rotates continuously while X/Y position the wire, creating the combined wire-workpiece path. The MV2400R's ADVANCE controller handles both operation modes through standard G-code programming.
02
B-axis wire EDM programming with continuous rotation requires specialized CAM software. Mitsubishi Electric's own CAPS-M CAM system supports MV2400R B-axis programming. Third-party options include Esprit, Open Mind hyperMILL, and Mastercam EDM module with rotary post-processors configured for the MV2400R. Index-and-cut B-axis work (the most common application) can be handled with manual programming or simpler CAM systems, as the B-axis move is a positioning command rather than a synchronized motion.
03
Yes. For external profiles on round workpieces, the wire can cut a complete circumference in one setup by programming the B axis to rotate the part while the wire maintains the radial cut position. Internal profiles on hollow cylindrical workpieces require the wire to be threaded through the bore, which may require manual threading at each index position depending on the geometry. The ADVANCE controller's re-threading sequence handles the wire threading at each new start position automatically in most geometries.
04
The MV2400S is a conventional 4-axis (X/Y/U/V) wire EDM with the same travel, generator, and accuracy specifications as the MV2400R, but without the B-axis rotary table. The MV2400S has a conventional flat work table with more straightforward fixture setup for planar EDM work. The MV2400R adds the B-axis rotary capability at a price premium. For shops whose work is entirely planar — punches, dies, mold inserts, flat plates — the MV2400S is the more practical and economical choice.
05
The rotary table on the MV2400R accommodates workpieces up to approximately 300 mm in diameter, limited by the Z-axis clearance, wire guide clearance, and the table's rotation envelope within the machine tank. The maximum workpiece weight on the rotary table is lower than the machine's overall 500 kg table capacity — consult Mitsubishi Electric's application engineering team for the specific rotary table weight and diameter limits for your component geometry.
