Mitsubishi EDM will be displaying its addition to the MV series of wire EDMs, the MV4800 Advance, designed for larger part production and submerged cutting as deep as 20". Available through MC Machinery Systems, the EDM features X-, Y- and Z-axis travels of 31.5" × 23.6" × 20.0" and can machine workpieces as large as 53.1" × 43.3" × 20.0". Combined with the machine's capacity, a linear shaft motor drive and glass scale feedback promote friction-free, highly accurate column movement throughout the X- and Y-axis range. The Meehanite base casting, joined with the stainless steel work tank, seal plate and work table contribute to a highly rigid machine structure, the company says. The three-sided work table, with a fourth rail across the back, facilitates the mounting of large workpieces. The machine is equipped with the M700 series control featuring a 15" touchscreen.

The Digital Matrix Sensor (DMX-S) and V350-V generator shape each spark to improve surface finish, reduce vibration and minimize electrode wear. This enables lower wire speed, which in turn reduces wire cost by as much as 60 percent, according to the company. Intelligent auto-threading systems are designed to anneal as much as 27 inches of wire, reducing curl ratio to less than 10 percent.
