EDM Enables Large-Part Production

Available from MC Machinery, the Mitsubishi EDM MV4800 Advance offers larger travels than other MV series machines, enabling production of large workpieces and submerged cutting as deep as 20". The wire EDM can accommodate workpieces as large as 53.1" × 43.3" × 20.0" with machine travels measuring 31.5" × 23.6" × 20.0".

The EDM features a rigid machine structure consisting of a Meehanite base casting, stainless steel work tank, seal plate and worktable. The three-sided worktable features an additional fourth rail across the back for easier mounting of large workpieces. A new linear shaft motor drive and glass scale feedback help to ensure friction-free, accurate column movement throughout the entire X- and Y-axis range. The EDM is equipped with the M700 series control with 15" touchscreen.

The EDM’s intelligent auto-threading system is designed to anneal as much as 27" of wire, reducing the curl ration to less than 10 percent, the company says. A digital matrix sensor (DMX-S) and V350-V generator shape each spark to improve surface finish, reduce vibration and minimize electrode wear. According to the company, these features enable a lower wire speed, reducing wire cost by as much as 60 percent.
