Overview
The Mitsubishi MP1200 is a high-precision wire EDM machine from Mitsubishi Electric, one of the top three wire EDM manufacturers globally alongside Sodick and GF Machining Solutions (AgieCharmilles). The MP series represents Mitsubishi's premium platform with advanced generator technology and precision mechanics.
The MP1200 features X/Y axis travels of 400 x 300 mm (15.7 x 11.8 in) with a maximum workpiece thickness of approximately 200 mm (7.87 in). The machine uses Mitsubishi's Tubular Shaft Motor technology on X and Y axes, eliminating backlash for superior positioning accuracy and surface finish. Positioning accuracy is +/- 1.5 microns with repeatability under +/- 1 micron.
Mitsubishi's optical fiber-based discharge technology delivers extremely fine surface finishes (under Ra 0.1 microns) and tight dimensional accuracy. The machine supports both standard brass wire and coated wires for optimized cutting speed or surface finish. Automatic wire threading (AWT) enables unattended operation through multiple cuts.
The M800 CNC control features a large touchscreen interface with intuitive operation. The control includes Mitsubishi's extensive cutting condition database covering a wide range of materials, thicknesses, and wire types. The E-Packs technology optimizes power consumption by adjusting generator settings based on cutting conditions.
New Mitsubishi MP1200 machines price $200,000-$350,000 depending on configuration. Competes with Sodick ALC600G, GF Machining Solutions CUT P series, and Makino U6 in the premium wire EDM segment.

Strengths & Limitations
Strengths
- Tubular Shaft Motors eliminate backlash for exceptional positioning accuracy and surface finish quality
- Sub Ra 0.1 micron surface finish capability for precision mold and die components
- Automatic wire threading enables unattended multi-cut cycles for lights-out production
- Mitsubishi's cutting condition database covers vast material/thickness combinations for quick setup
- E-Packs technology optimizes power consumption, reducing energy costs on continuous operation
- M800 touchscreen control provides intuitive operation with comprehensive process monitoring
Limitations
- $200,000-$350,000 is premium pricing in the wire EDM market
- Mitsubishi's wire EDM dealer network in North America is smaller than some competitors
- Wire EDM cutting speed is inherently slow compared to other machining processes -- this is a precision tool
- M800 control programming differs from Fanuc-based EDMs, requiring operator adaptation
- 400 x 300 mm travel limits maximum part size -- larger parts need the MP2400 or similar

Frequently Asked Questions
01
$200,000-$350,000 new depending on table size, AWT options, and accessories. Used (2018-2023) $100,000-$200,000.
02
Linear motors with zero backlash and direct drive, eliminating the gear and ball screw components that introduce positioning error. This provides smoother motion, better surface finish, and higher positioning accuracy than ball screw drive systems.
03
Sub Ra 0.1 microns with multiple skim cuts and fine wire. Typical production finishes range from Ra 0.2-0.8 microns depending on the number of cuts and wire selection.
04
Yes. Automatic wire threading re-threads the wire after breakage or when moving between features. Combined with the cutting condition database, the MP1200 can run through multi-cut cycles unattended for extended periods.
05
Any electrically conductive material: tool steel, hardened steel, stainless steel, titanium, tungsten carbide, Inconel, copper, aluminum, and more. Material must be electrically conductive for the EDM process to work.
