Mitsubishi EDM’s MV1200R wire EDM from MC Machinery features improvements over the company’s previous EDM models. The MV1200R incorporates noncontact cylindrical drive technology, an improved power supply, automatic threading and deeper submerged wire-threading capabilities. New cylindrical drive technology uses a linear shaft motor with a round magnetic shaft, creating a non-contact design using the full 360 degrees of magnetic flux. The design is said to deliver no wear, no cogging and no backlash for improved accuracy, speed and efficiency.

Travels measure 15.7" × 11.8" × 8.7" in the X, Y and Z axes. The machine accommodates workpieces ranging to 31.9" × 17.6" × 8.5" and maximum submerged workpiece weight is 1,102 lbs. Submerged machining is possible to 8.7" deep. The EDM accommodates wires ranging from 0.004" to 0.012", approximately. A digital matrix sensor shapes each spark, reducing electrode wear.

  • What It Takes to Do Unattended Wire EDM

    The promise of running a wire EDM for long stretches without much operator attention is enticing, but many shops never manage to pull this off. Here are tips to make it happen, as offered by Mark Cicchetti, EDM technical director for Absolute Machine Tool’s Accutex EDM product line.

  • The Hidden Cost Of EDM Wire Consumption

    Excessive wire consumption on a wire electrical discharge machine is costly. Technology that allows slower unspooling speeds without compromising results appears to be the answer.

  • Anti-Electrolysis Developments In Wire EDM

    Originally, wire EDM had two things going against it. It was slow, and often it left an undesirable surface finish. In the last few years, wire EDM builders have fixed the speed problem. Now they're well on their way to fixing the surface finish problem.
