About the Mitsubishi MV2400-R M800 Wire EDM
There's a gap in most wire EDM lineups: the small, accurate machines can't handle large parts, and the large machines sacrifice accuracy for capacity. The Mitsubishi MV2400-R M800 Advance Plus closes that gap.
It shares the MV2400-S's full work envelope — 23.6" × 15.7" × 12.2" machine travels, workpieces up to 41.3" × 32.3", up to 2,204 lb submerged. But where the MV2400-S applies the non-contact cylindrical drive to X and Y axes only, the MV2400-R Advance Plus extends it to all four axes: X, Y, U, and V. That's the difference between a production EDM and a high-accuracy EDM in a large-format frame. The MV2400-R is both.
The result is ±0.0001″ positional accuracy across the full work envelope — including tapered features and complex angular geometries on large workpieces. And with optional 4Ra surface finish capability, the MV2400-R eliminates downstream grinding on large mold cavity surfaces and precision tooling faces that the MV2400-S's accuracy level can't address.
Steve Brown at Iron Machine Tool regularly works with aerospace suppliers and large-format mold shops in the Midwest who need exactly this combination. The MV2400-R is the machine they land on when large part size and tight tolerance exist on the same drawing at the same time.

Key Capabilities of the MV2400-R M800
Four-Axis Advance Plus Drive — On a Large Machine
This is the MV2400-R's defining feature and the specific reason shops choose it over the MV2400-S. Every other machine in the MV2400 class applies the non-contact cylindrical drive to X and Y only. The MV2400-R Advance Plus extends that same zero-backlash, no-wear system to U and V as well. What that means in production: your straight cuts, taper cuts, and complex angular geometry all hold ±0.0001″ accuracy. There's no degradation on the off-axis moves. For shops producing tight-tolerance tapered features or complex angular geometry on large workpieces, no other machine in this price class matches it. Mitsubishi backs the drive system with a 10-year positioning warranty.
Optional 4Ra Surface Finish on Large Parts
Full-time AEII anti-electrolysis power supply protection combined with the Advance Plus drive system and DMX-S Digital Matrix Sensor spark shaping enables optional 4Ra surface finishes — on large workpieces, in production conditions. For shops finishing large mold cavity surfaces where 4Ra eliminates the hand polishing step, the time savings compound across a full production run. If the MV2400-S's accuracy level is leaving you with secondary grinding operations on large parts, the MV2400-R is where that stops.
Large Workpiece Capacity — No Accuracy Trade-Off
The MV2400-R handles workpieces up to 41.3" × 32.3" × 12.0" and 2,204 lb submerged weight — identical to the MV2400-S. The accuracy upgrade is entirely in the drive system. Shops moving from an MV2400-S to the MV2400-R don't give anything up in capacity. They gain ±0.0001″ accuracy and optional 4Ra finish without any reduction in the work they can physically accommodate.
Auto-Threading at Scale
The 14-inch annealing length auto-threading system handles wire break recovery across the full travel range of the machine — including on large, heavy workpieces at the MV2400-R's dimensional limits. For shops running large die sets or mold bases overnight without a crew on the floor, threading reliability at scale is what makes that production schedule work. The MV2400-R handles it.
M800 Control — Identical Across the MV Series
The 19-inch M800 touchscreen, FTP/Ethernet connectivity, 1 GB program storage, and remote360 monitoring are identical to the MV2400-S and every other M800-equipped machine in the Mitsubishi lineup. Operators trained on any MV machine can run the MV2400-R without retraining. Production data is accessible remotely. Programs transfer from CAM systems over Ethernet.
Industries That Rely on the Mitsubishi MV2400-R M800
The MV2400-R is the machine for shops where "large" and "accurate" can't be two separate operations on two different machines. If your part requires the MV2400 work envelope and a tolerance callout that the MV2400-S can't reliably hold, the MV2400-R is the answer.
Aerospace Structural and Precision Components
Large housings, actuator brackets, and structural frames where the geometry requires the MV2400 work envelope but the tolerance callouts on the drawing demand ±0.0001″. In aerospace manufacturing, those two requirements exist on the same part regularly. The MV2400-R handles them in a single setup — no splitting operations between a large machine for capacity and a smaller machine for accuracy.
Heavy Mold Production
Large cavity molds and multi-plate die sets where the surface finish on cut faces directly determines mold performance, part ejection quality, and service life. If the MV2400-S's accuracy is sufficient for your mold work, use the MV2400-S. If your inspection process is regularly flagging surface finish or dimensional issues on large cavity features, the MV2400-R's 4Ra optional capability and ±0.0001″ accuracy close that gap.
Defense Manufacturing
Precision components for guidance systems, weapon system housings, and test fixtures where tolerance specifications don't flex regardless of part size. Defense work that sits at the intersection of large format and tight tolerance is precisely where the MV2400-R was designed to operate.
Large-Format Precision
Inspection fixtures, assembly tooling, and metrology reference parts that must maintain dimensional accuracy across extended features. On large fixtures where a tolerance stack-up causes problems at final inspection, the MV2400-R's four-axis Advance Plus drive eliminates the accuracy degradation that happens on off-axis moves with the MV2400-S.
General Precision Machining
Any shop producing close-tolerance components in hardened steel, carbide, titanium, or exotic alloys where part size has outgrown the MV1200-S. The MV2400-S brings the same low-cost-of-operation production EDM capability to a larger work envelope — without requiring a fundamentally different machine or operating budget to match.
Why Buy the MV2400-R Through Iron Machine Tool
Iron Machine Tool is the authorized Mitsubishi EDM distributor for the Midwest not a reseller, not a broker. Headquartered in Minneapolis, Minnesota, serving manufacturers across Minnesota, Wisconsin, Illinois, Iowa, and the surrounding region.
The MV2400-R vs MV2400-S conversation is one Steve Brown has had with a lot of shops and the honest version is straightforward: if your parts call for standard production tolerances in a large work envelope, the MV2400-S is the more cost-effective machine. If your drawings have ±0.0001″ tolerance callouts on large features, or if your surface finish requirements are generating secondary grinding operations you'd rather eliminate, the MV2400-R justifies the step up.
Steve can look at your actual drawings and part requirements and give you a direct answer on which machine fits your work — before you commit to a capital equipment purchase. That's the kind of pre-sales technical conversation that a national catalog distributor doesn't have the application knowledge to provide.
That's the practical difference between buying from Iron Machine Tool and buying from a catalog:
- Direct technical guidance ; based on your actual drawings and production requirements, not a spec sheet comparison
- Honest machine selection ;Steve will tell you if the MV2400-S covers your work and saves you the step-up cost
- Local coordination ; Midwest-based service and support, not routed through a national hub
The Support Infrastructure Behind Every Machine
Iron Machine Tool gives you full access to Mitsubishi's Triple Diamond Partnership Program ; a complimentary preventative maintenance visit within the first year, remote360 monitoring capability, and Mitsubishi's dedicated parts supply chain. For shops where machine uptime directly affects delivery commitments, the support structure behind the machine is not secondary.

Frequently Asked Questions — Mitsubishi MV2400-R M800
A: Both machines share the same work envelope (23.6" × 15.7" × 12.2"), the same M800 control, and the same workpiece capacity (41.3" × 32.3", up to 2,204 lb submerged). The difference is the drive system. The MV2400-S applies the non-contact cylindrical drive to X and Y axes only. The MV2400-R Advance Plus extends that drive to X, Y, U, and V, delivering ±0.0001″ positional accuracy and an optional 4Ra surface finish on all cut geometry — including tapers and complex angular features. It matters when your tolerance callouts require it, or when your surface finish requirements are generating secondary processing work on large parts that you want to eliminate.
A: The optional 4Ra finish capability on the MV2400-R is achievable in production conditions, not just on demonstration cuts. It requires the finishing pass conditions enabled by the Advance Plus drive, full-time AEII power supply protection, and DMX-S spark shaping. For shops finishing large mold cavity surfaces where 4Ra eliminates downstream hand polishing, this is the specific reason to choose the MV2400-R over the MV2400-S. If you want to validate this on your specific material before purchasing, Steve Brown at Iron Machine Tool can arrange a test cut through Mitsubishi's facility.
A: Yes and aerospace structural work at the intersection of large format and tight tolerance is exactly the application the MV2400-R was designed for. The four-axis Advance Plus drive maintains ±0.0001″ positional accuracy across the full 23.6" × 15.7" travel range, including on tapered features and complex angular geometry. Parts in titanium, Inconel, and hardened aluminum come off the machine with zero heat-affected zone, no cutting force distortion, and dimensional accuracy across the full feature set.
A: Yes — identical. Maximum workpiece dimensions are 41.3" × 32.3" × 12.0" (1,050 × 820 × 305 mm), with a submerged weight capacity of 2,204 lb (1,000 kg). The difference between the MV2400-S and MV2400-R is entirely in drive system accuracy — not in what workpieces they can physically accommodate. If your parts fit in the MV2400-S, they fit in the MV2400-R.
