Mitsubishi MV2400-ST M800 Wire EDM — Cut Tall Parts Up to 16.5" High
Reviewed and recommended by Steve Brown, Founder — Iron Machine Tool | Authorized Midwest Mitsubishi EDM Distributor
About the Mitsubishi MV2400-ST M800 Wire EDM
Most shops don't realize they need the MV2400-ST until they've spent months working around a Z-axis limit that isn't going away. Parts get tilted at an angle to fit in the tank. Tall workpieces get split across two setups. Jobs get sent to outside shops because the current machine simply can't accommodate the height. The MV2400-ST M800 exists to end those workarounds.
The MV2400-ST shares the same X and Y travels as the MV2400-S — 23.6" × 15.7" — the same M800 control, the same non-contact cylindrical drive, the same low operating cost. The difference is in the Z-axis: 16.5" of travel versus 12.2" on the standard MV2400-S. That 4.3-inch difference is what makes extrusion dies, deep-cavity mold inserts, heavy punch-and-die sets, and thick structural aerospace components practical EDM work instead of a fixturing problem.
Steve Brown at Iron Machine Tool has placed MV2400-ST machines with Midwest extrusion die shops and heavy mold makers who couldn't solve the tall-part problem any other way. The conversation is always the same: the shop has been angling parts or splitting setups for too long, they've found the MV2400-ST, and they want to know if it solves their specific height requirement. It usually does.

Key Capabilities of the MV2400-ST M800
16.5" Z-Axis — More Than a Number
The difference between 12.2" and 16.5" of Z-travel is the difference between setups that work and setups that don't. Extrusion die profiles routinely require cutting depths of 12 to 16 inches. Deep-cavity mold inserts and heavy blanking die plates in tool steel exceed 12 inches regularly. Thick structural aerospace panels hit the same wall. The MV2400-ST accommodates all of those parts directly — no tilting, no splitting, no second operation on a different machine. Maximum workpiece height is 16.3", and the machine fully submerges and cuts at any point in that range.
Auto-Threading at Full Depth — Unattended
Auto-threading through 16 inches of workpiece height is not a trivial capability. A lot of machines can claim tall-part access but fall apart on threading reliability at depth. The MV2400-ST's 14-inch annealing length threading system handles wire breaks, gap threading, and production recovery at the machine's full depth range without operator intervention. For shops running overnight or weekend production on tall extrusion dies or thick mold plates, this is what makes lights-out operation genuinely practical — not just a feature on a brochure.
Same Operating Cost as MV2400-S
Stepping up to the MV2400-ST doesn't change the per-part running cost. Wire consumption, filter changes, and energy use are identical to the MV2400-S profile — same V350-V AEII power supply with Digital Spark Control, same DMX-S Digital Matrix Sensor spark shaping, same non-contact cylindrical drive on X and Y. If the MV2400-S economics work for your shop, the MV2400-ST numbers look the same. The only thing you're paying for is the additional Z-travel that solves your tall-part problem.
Same Drive Accuracy on X and Y
The non-contact cylindrical drive on the MV2400-ST covers X and Y axes — the same zero-backlash, no-wear system backed by Mitsubishi's 10-year positioning warranty that's on the MV2400-S. The extended Z-axis does not compromise X and Y accuracy. Positioning resolution stays at 0.000002" (2 µin) across the full 23.6" × 15.7" travel range.
M800 Control — No Retraining
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 lineup. Operators trained on the MV2400-S or any MV machine are ready to run the MV2400-ST the same day. Production managers get real-time machine status and output data remotely.
Industries That Rely on the Mitsubishi MV2400-ST M800
The MV2400-ST serves a specific set of manufacturing environments where part height is the constraint — not part size in X and Y, not tolerance, not surface finish. If tall parts are the problem, this is the machine that solves it.
Extrusion Die Manufacturing
Aluminum and plastic extrusion die profiles require cutting depths of 12 to 16 inches as a matter of routine. This is the MV2400-ST's home application — the machine it was designed around. Extrusion die shops that have been tilting their dies or splitting cuts across multiple setups use the MV2400-ST to eliminate that overhead completely. One setup, full depth, full submersion, production-ready parts.
Deep-Cavity Mold Production
Injection molds, blow molds, and compression mold plates with deep cavity features that exceed 12 inches of depth. The MV2400-ST handles them in a single submerged setup — no secondary operation on a larger but less accurate machine, no fixturing compromises that affect the geometry of the finished cavity.
Heavy Punch-and-Die Sets
Thick progressive die plates and heavy blanking die sets in tool steel where the plate itself exceeds 12 inches and can't be angled in a standard EDM tank. The MV2400-ST's 16.3" maximum workpiece height covers the full range of heavy die plate work that the standard MV2400-S can't accommodate.
Aerospace Structural Components
Fuselage frames, spar brackets, and thick aluminum structural panels where the workpiece height drives the machine selection — not the tolerance or surface finish requirement. For aerospace structural work where the part simply won't fit in a standard MV2400-S, the MV2400-ST is the Mitsubishi answer.
Thick-Plate Precision Machining
Any shop cutting through hardened plates, fixtures, or assemblies taller than 12 inches where wire EDM's burr-free, distortion-free, no-heat cutting is required. The MV2400-ST brings the full capability of the MV2400 platform to the tall-part work that was previously going elsewhere or being handled with time-consuming workarounds.
Why Buy the MV2400-ST 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-ST is a niche machine — it doesn't outsell the MV2400-S by volume because most work fits in 12 inches. But for the shops whose work doesn't fit, it's not niche at all. It's the only machine that solves the problem. Steve Brown at Iron Machine Tool knows which shops need it because the conversation always starts the same way: a shop describes their tall-part workaround, and the MV2400-ST is where the conversation ends.
When Steve talks to a shop about the MV2400-ST, the first question isn't about the machine — it's about the parts. What's your tallest part? What's your current process for handling it? Does 16.3" of maximum workpiece height solve the problem, or do your requirements push further toward the MV4800-S with its optional 32" configuration? That's the kind of pre-sales conversation that determines whether a capital equipment purchase actually solves the production problem it was bought to solve.
That's the practical difference between buying from Iron Machine Tool and buying from a catalog:
- Application-first guidance — Steve looks at your parts before he talks about the machine
- Honest fit assessment — if the MV2400-ST doesn't cover your height requirement, he'll tell you before you buy
- 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 an EDM sitting idle means extrusion die orders are late, the support structure behind the machine matters as much as the machine itself.

Frequently Asked Questions — Mitsubishi MV2400-ST M800
A: The MV2400-ST provides 16.5" (419 mm) of Z-axis travel and accommodates workpieces up to 16.3" (414 mm) high. The standard MV2400-S provides 12.2" (310 mm) of Z-travel with a maximum workpiece height of 12.0" (305 mm). The difference is 4.3 inches — which is the gap between parts that fit and parts that don't for extrusion die profiles, deep-cavity mold inserts, and thick die plates. In every other specification, the MV2400-ST and MV2400-S are identical: same X and Y travels (23.6" × 15.7"), same M800 control, same non-contact cylindrical drive, same operating cost.
A: No on both counts. The MV2400-ST maintains the same non-contact cylindrical drive on X and Y as the MV2400-S, with the same 0.000002" (2 µin) minimum drive resolution and 10-year positioning warranty. The extended Z-axis does not change the machine's X and Y positional accuracy. Operating costs — wire consumption, filter changes, energy use per cut — are also identical to the MV2400-S profile. The only variable that changes is Z-travel.
A: Yes. The auto-threading system is specifically designed to handle the full depth range of the machine — including workpieces at the maximum 16.3" height. The 14-inch annealing length threading system manages wire breaks, gap threading, and production recovery at full depth without operator intervention. This is one of the specific reasons shops choose the MV2400-ST over trying to tilt tall parts in a shorter machine: you can't run tilted setups overnight unattended. You can run the MV2400-ST overnight without anyone on the floor.
A: Almost certainly yes — but the answer depends on your specific part heights. If your tallest parts are consistently in the 12" to 16" range, the MV2400-ST solves that problem directly. If your parts regularly exceed 16", the MV4800-S with optional 32" cutting height is the correct machine. Steve Brown at Iron Machine Tool will ask for your specific part dimensions before making a recommendation. Contact Iron Machine Tool with your height requirements and current setup and he'll tell you straight which machine fits.
A: Yes. Iron Machine Tool is the authorized Mitsubishi EDM distributor for the Midwest, headquartered in Minneapolis, Minnesota. The MV2400-ST is a machine Steve Brown knows well — he's placed it with Midwest extrusion die shops and heavy mold makers whose work pushed past the MV2400-S's Z-axis limit. Contact Steve Brown directly with your part height requirements to discuss fit and availability.
