About the Mitsubishi MV4800-S M800 Wire EDM
When a shop calls about the MV4800-S, the conversation usually starts the same way: the work has gotten too big for everything else in the lineup. Parts that won't fit in an MV2400. Mold bases that exceed 40 inches. Die sets that are too heavy and too tall for the MV2400-ST. Aerospace structural assemblies where the only machine that fits the work envelope is the largest one Mitsubishi makes.
The MV4800-S M800 provides X, Y, Z travels of 31.5" × 23.6" × 20.1" — the largest work envelope in Mitsubishi's standard MV wire EDM series. Maximum workpiece dimensions of 49.2" × 40.2" × 19.9". Up to 4,409 lb of submerged workpiece weight. And with the optional extended configuration, cutting height reaches 32 inches — covering the full range of large die sets, mold base assemblies, and structural aerospace frames that exceed every other machine in the lineup.
Before anything else on this page: the overview table previously listed "Model: MV2400-ST M800" — that was a data entry error and has been corrected. This page is for the MV4800-S M800.
Steve Brown at Iron Machine Tool has placed MV4800-S machines with Midwest manufacturers cutting large automotive tooling and heavy aerospace structural work. It's not the right machine for every shop — and Steve will tell you that directly if your requirements are better served by the MV2400-S or MV2400-ST. But for shops whose work has genuinely outgrown everything else, the MV4800-S is the answer.
Cutting parts that exceed 40" × 30" or need a 20"+ Z-axis?
The MV4800-S is a significant capital purchase. Steve Brown's first step is always a real conversation about your parts dimensions, weight, production volume, floor plan before anything else. That's how you buy the right machine.

Key Capabilities of the MV4800-S M800
Largest Work Envelope in the MV Series
49.2" × 40.2" × 19.9" maximum workpiece dimensions. 31.5" × 23.6" × 20.1" machine travels. 4,409 lb maximum submerged workpiece weight — more than double the MV2400 series. These are the numbers that define the MV4800-S as the machine for manufacturers whose work has outgrown everything else in the lineup. The optional 32" cutting height extends the Z-axis further, covering the largest die sets and mold base assemblies that would hit the ceiling in any other configuration.
Thermal Buster — Temperature Control at Scale
Large machine castings accumulate thermal drift during long cutting operations in a way that smaller machines don't. A casting the size of the MV4800-S expands and contracts with temperature changes — and on a large workpiece, that thermal movement shows up as dimensional error across the part surface. The MV4800-S addresses this directly with the Thermal Buster system: integrated temperature sensors throughout the casting and chiller-driven dielectric fluid circulation that maintains consistent thermal control across the entire machine frame. For multi-hour cuts on large mold bases or aerospace structural panels where dimensional accuracy must hold from first pass to last, thermal stability is the variable that determines whether the part passes inspection.
27" Auto-Threading Annealing Length
The MV4800-S carries an auto-threading annealing length of over 27 inches — significantly longer than the MV2400 series machines. At full 20" workpiece height, the threading system handles wire break recovery, gap threading, and production continuity without operator intervention. The 27" annealing length is specifically engineered for the MV4800-S's depth range — it's what makes overnight unattended production on the largest workpieces a practical reality rather than an optimistic assumption.
Built-In Wire Spool — Floor Space Recovered
Previous large-format wire EDM configurations required an external wire spool cabinet sitting alongside the machine — adding footprint in shops where large-machine floor space is already at a premium. The MV4800-S moves the wire spool to a built-in unit integrated into the machine body. The redesigned dielectric fluid tank simultaneously reduces machine width. For shops planning their floor layout around the MV4800-S, this is a meaningful space recovery.
Wide Tank Door Window
The MV4800-S features a new wide window in the tank door — giving operators visual access to the machining process even during fully submerged deep cutting operations. On large, complex workpieces where visual monitoring matters, this is an ergonomic detail that makes a real operational difference.
M800 Control — Same Interface, Largest Machine
The 19-inch M800 touchscreen, FTP/Ethernet connectivity, 1 GB program storage, and remote360 monitoring are identical to every other M800-equipped machine in the Mitsubishi MV lineup. Operators who have run any MV machine can run the MV4800-S without retraining. Production managers get real-time machine status, alarms, and output data remotely — important on a machine running large jobs over extended periods.
Industries That Rely on the Mitsubishi MV4800-S M800
The MV4800-S serves manufacturers whose work has genuinely exceeded what every other machine in the MV lineup can accommodate. This is not an upgrade from the MV2400-S for shops that need "a little more room." It's the machine for shops with fundamentally larger scale requirements.
Large Automotive Tooling
Large progressive die sets, draw dies, and trim dies where the overall assembly footprint exceeds 40" × 30". Tier 1 automotive suppliers producing large-format stamping tooling for body panel and structural component programs routinely encounter work that the MV2400 series can't accommodate. The MV4800-S's 49.2" × 40.2" table handles that class of tooling as everyday production work.
Aerospace Structural Manufacturing
Large aluminum and titanium structural components wing ribs, spar brackets, fuselage frames, and thick structural panels where the combination of workpiece size and material requirements pushes past the MV2400 series capacity. EDM's burr-free, zero-heat cutting and no-cutting-force process is frequently the only practical method for these materials in these sizes. The MV4800-S is the machine that makes that work possible in a Midwest shop without outsourcing.
Heavy Mold Production
Large injection mold bases, blow mold assemblies, and compression mold plates where the combination of workpiece size and weight up to 4,409 lb submerged exceeds what the MV2400 series can handle. Large mold shops producing tooling for automotive, industrial packaging, and consumer goods in high-complexity configurations use the MV4800-S when mold base size is the constraint.
Defense and Industrial Manufacturing
Large precision components for ground vehicle systems, energy sector equipment, and industrial machinery where the work envelope is the primary machine selection driver. Defense manufacturing work that involves large structural or housing components in hardened steel or exotic materials is a consistent MV4800-S application in the Midwest market.
Large-Format Die Casting Tooling
Die casting tools for large aluminum and zinc components automotive transmissions, structural housings, powertrain cases require large work envelopes and significant workpiece weight capacity. The MV4800-S's 4,409 lb submerged capacity and 49.2" × 40.2" table accommodate the die casting tooling class that other machines can't.
Why Buy the MV4800-S 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 MV4800-S is a machine Steve Brown takes seriously before the first quote goes out. It's a significant capital purchase — and the shops that need it usually know they need it before they call. They've hit the capacity wall on their MV2400. They're sending large jobs to outside shops. They've priced the MV4800-S and they want to talk to someone who knows the machine and understands their production environment before committing.
That's exactly what Steve Brown does. His pre-sales process for the MV4800-S starts with the parts: what are your actual largest workpiece dimensions, what is the weight, what does your floor plan look like, does the standard 20" Z-axis cover your requirements or does your work push toward the 32" optional configuration? Those answers determine whether the MV4800-S is the right investment and what configuration fits the production requirement.
That's the difference between Iron Machine Tool and a national catalog distributor:
- Capital equipment guidance — Steve reviews your actual work requirements before talking pricing
- Configuration expertise — standard 20" Z vs optional 32" is a decision that affects your production capability for years
- Local Midwest coordination — service and support from a distributor based in your region, not routed from a national hub

Frequently Asked Questions Mitsubishi MV4800-S M800
A: The MV4800-S provides 20.1" (511 mm) of Z-axis travel as standard, accommodating workpieces up to 19.9" (505 mm) high. The optional extended configuration raises cutting height to 32" (813 mm) — covering the largest die sets, mold base assemblies, and structural aerospace frames in the Mitsubishi MV lineup. The 32" option requires specific guide and tank configuration. The MV4800-S also carries an auto-threading annealing length of over 27 inches, which means the threading system handles reliable wire break recovery at the machine's full depth range — including the optional 32" extended configuration. Contact Iron Machine Tool to discuss whether the standard 20" or optional 32" fits your specific workpiece requirements.
A: The MV4800-S accepts workpieces up to 49.2" × 40.2" × 19.9" (1,250 × 1,020 × 505 mm) at standard configuration. Maximum submerged workpiece weight is 4,409 lb (2,000 kg) more than double the MV2400 series' 2,204 lb capacity. This covers the full range of large mold bases, heavy die assemblies, and structural components that exceed the MV2400 series in both footprint and weight. The MV4800-S is the largest-capacity wire EDM in Mitsubishi's standard MV series.
A: The Thermal Buster is a temperature regulation system integrated into the MV4800-S machine casting. It uses sensors distributed throughout the casting and chiller-driven dielectric fluid circulation to maintain thermal stability across the large machine frame. On a machine the size of the MV4800-S, thermal drift during extended cutting operations is a real accuracy concern — large castings expand and contract more than smaller ones, and that movement translates directly into dimensional error on the finished part. The Thermal Buster keeps the casting temperature consistent throughout the cut, which keeps dimensional accuracy consistent from the first pass to the last. On multi-hour cuts of large aerospace structural panels or mold bases, this system is the difference between parts that pass inspection and parts that need rework.
A: The MV4800-S uses wire diameters from 0.006" to 0.012" (0.15 mm to 0.3 mm). This starting point is slightly larger than the 0.004" minimum on the MV1200 and MV2400 series. The MV4800-S is optimized for the larger cross-sections, heavier materials, and deep submerged cutting typical of large-format wire EDM work not for micro-geometry cutting or ultra-fine feature work. If your application involves both large part size and fine-feature geometry requiring 0.004" wire, contact Steve Brown at Iron Machine Tool to discuss whether the MV4800-S fits or whether a different configuration is more appropriate.
A: Yes. Iron Machine Tool is the authorized Mitsubishi EDM distributor for the Midwest, based in Minneapolis, Minnesota. The MV4800-S is a significant capital purchase and Steve Brown's approach is to start with your production requirements part dimensions, workpiece weight, floor plan, Z-axis requirements before the conversation moves to pricing and configuration. That pre-sales process is what ensures you buy the right machine and the right configuration for your work. Contact Iron Machine Tool to start that conversation.
