About the Mitsubishi SV28 Sinker EDM
Iron Machine Tool distributes the Mitsubishi SV28 Sinker EDM to manufacturers across Minnesota, Wisconsin, Iowa, and Illinois through MC Machinery Systems the authorized North American distribution channel for Mitsubishi Electric EDM equipment.
The SV28 extends the SV series to a large-format work envelope 41.3" x 29.9" x 13.8" with 4,409 lb workpiece capacity for die blocks, large mold bases, and industrial workpieces that exceed what the SV12P can accommodate. It carries the same Maisart AI, M800 D-CUBES control, and Thermal Displacement Compensation System found in the SV series, scaled to a machine configuration built for heavy production work.
For large stamping die manufacturers, heavy mold makers, and Midwest production shops running oversized workpieces that require SV-series surface finish performance at a larger work envelope, the SV28 is the step up that keeps SV-level accuracy at the scale the work requires.
Running large die blocks or oversized mold bases that have pushed past what your current sinker EDM can handle and surface finish quality still matters?
The SV28 is built for shops that have outgrown the SV12P's table but still need SV-series finishing performance. Steve Brown's first step is always a real conversation about your workpiece dimensions, weight, surface finish requirements, and floor plan before anything else. That's how you buy the right machine.

Key Capabilities of the Mitsubishi SV28 Sinker EDM
Large-Format Work Envelope with SV-Series Performance
At 41.3" x 29.9" x 13.8" and 4,409 lb workpiece capacity, the SV28 handles the class of large die blocks and mold bases that the SV12P cannot. The SV28 delivers the same Maisart AI spark control and M800 D-CUBES control platform found across the SV lineup — at a machine scale where those capabilities are applied to larger, heavier workpieces in production environments.
Thermal Displacement Compensation System
The SV28 includes Mitsubishi's Thermal Displacement Compensation System as standard — temperature sensors that continuously monitor changes in the work tank and machine environment, compensating for thermal drift across the machine structure. On a large-format machine running extended burn cycles on heavy workpieces, thermal compensation is the difference between consistent dimensional results and progressive accuracy drift.
Maisart AI and IDPM3 Control
The SV28 runs Maisart AI with the IDPM3 adaptive spark control to optimize electrode wear, stabilize servo control, and enable automatic depth recognition across large workpiece geometries. Electrode wear reduction up to 40% has direct cost implications on large workpieces where electrode material and setup time are significant production cost factors.
M800 D-CUBES Control with Remote360
The M800 controller with 19-inch touchscreen and LCD hand pendant provides full machine access. ESPER II Navigator guides programming through a step-by-step interface. Remote360 cloud-based machine monitoring is included standard, providing real-time run time, idle time, and remote diagnostic access from any device.
Who Should Evaluate the SV28
Large stamping die manufacturers running die blocks that exceed 35" x 25" in footprint, heavy mold shops producing large mold bases where SV-series surface finish performance is required at a larger scale, and production shops where the combination of workpiece size — over 4,000 lb — and surface finish quality rules out the SG28 as the appropriate alternative.
Industries That Rely on the Mitsubishi SV28 Sinker EDM
The SV28 runs a fixed-table, column-movement configuration built for heavy workpieces up to 4,409 lb. In place of a drop tank, the SV28 uses an automatic elevation tank that raises and lowers hydraulically. The GV80P generator is standard with an optional GV120P upgrade. The Thermal Displacement Compensation System is standard temperature sensors that monitor and compensate for thermal drift across extended burn cycles on large workpieces. Remote360 monitoring is included standard.
Large Stamping
Large progressive die sets, draw dies, and trim dies where the die block footprint exceeds 35" x 25" and SV-series surface finish performance is a requirement on the die cavity surfaces. Large Midwest stamping die shops use the SV28 where the SV12P's table is the constraint not the control system or the surface finish capability.
Heavy Mold Production
Large injection mold bases, compression mold plates, and structural mold components where the workpiece weight approaches or exceeds 4,000 lb and the cavity surface finish is a direct quality requirement. Heavy mold shops producing tooling for automotive, industrial packaging, and consumer goods use the SV28 when mold base size exceeds the SV12P's capacity.
Industrial and Energy Sector Manufacturing
Large precision components for energy sector equipment, industrial machinery, and heavy manufacturing where the work envelope is the primary machine selection driver and surface finish performance on the machined features is still a quality requirement. The SV28 handles these workpieces with the same AI spark control and thermal compensation that precision mold and die shops rely on.
Aerospace Tooling
Large structural tooling components, fixture plates, and forming dies for aerospace applications where the individual workpiece is large-format and the tolerance and surface finish requirements are non-negotiable. The SV28 machines titanium, carbide, and aerospace alloys with no cutting force and no heat distortion, with thermal displacement compensation maintaining accuracy across extended machining cycles on heavy workpieces.
Why Buy the SV28 Through Iron Machine Tool
Iron Machine Tool is the authorized Mitsubishi EDM distributor for the Midwest. Not a reseller, not a national catalog operation. Headquartered in Minneapolis, Minnesota, serving manufacturers across Minnesota, Wisconsin, Iowa, and Illinois.
The SV28 is a significant machine for shops that have specifically outgrown the SV12P — in workpiece size, not in surface finish requirements. Steve Brown's pre-sales approach starts with your workpiece dimensions, weight, and surface finish target. If the SV12P's 35" x 25" envelope is the constraint and the SG28 doesn't meet your finishing requirements, the SV28 is the machine that closes both gaps.
That's the difference between Iron Machine Tool and a catalog distributor:
- Honest scale assessment
Steve reviews your actual workpiece dimensions and finishing requirements before any pricing discussion. If the SG28 covers your work at a lower cost, he'll tell you that.
- Large machine installation support
Iron Machine Tool coordinates installation, commissioning, and operator training for large-format machines through MC Machinery Systems' factory support network. Floor plan, power requirements, and rigging are part of the pre-sales conversation.
- Local Midwest coordination
Service and support from a distributor based in your region, with access to Mitsubishi's regional service technicians in MN, WI, IL, and IA. Not routed through a national hub.
Contact Steve Brown at Iron Machine Tool to start the right conversation. Your surface finish requirements and tolerance targets first, pricing second
Frequently Asked Questions Mitsubishi SV28 Sinker EDM
A: Both the SV28 and SG28 are large-format sinker EDMs with similar work envelopes. The SV28 carries the SV-series power supply and Thermal Displacement Compensation System designed for applications where surface finish performance and thermal accuracy are requirements alongside workpiece size. The SG28 is optimized for high-productivity large-format work where production throughput is the primary priority. If mirror-finish quality and thermal stability matter at large scale, the SV28 is the appropriate choice.
A: Thermal Buster is a Z-axis cooling mechanism combined with ambient temperature sensors that continuously monitor and compensate for thermal expansion in the machine structure. Even small ambient temperature changes cause measurable dimensional drift on fine-tolerance sinker EDM work. Thermal Buster eliminates that variable a critical capability for medical device tooling, optical mold work, and any application where the tolerance band is under 0.0002".
A: The SV28 handles workpieces up to 4,409 lb (2,000 kg). This makes it one of the highest-capacity sinker EDMs in the Mitsubishi lineup that still carries full SV-series surface finish capability.
A: Yes. Iron Machine Tool distributes the Mitsubishi SV28 Sinker EDM across Minnesota, Wisconsin, Iowa, and Illinois through MC Machinery Systems. Contact Steve Brown directly to discuss the SV28 for your application and production requirements.
A: Yes. Every SV28 includes Remote360 cloud-based machine monitoring as standard equipment real-time visibility into machine run time, idle time, and remote diagnostics from any device.
