Wire EDM

April 10, 2019

Expanding MuShield’s Shop Floor – The Advantages of Wire EDM

Wire EDM isn’t new to the manufacturing industry. That said, it is new to us here at MuShield. And we couldn’t be more thrilled to add it to the constantly improved puzzle we have in place on our shop floor. We strive to offer our loyal customers, and new ones coming in the door, with the best technologies and manufacturing production practices/options in the game.

That said, welcome Wire EDM to our list of capabilities.

What is Wire EDM?

In short, Wire EDM is a process of cutting that creates incredibly complex design and shapes unachievable by other machining methods.

How precise are these cuts?

No thicker than a human hair…

Instead of a blade like a bandsaw or something similar, Wire EDM uses an electrically charged wire to remove microscopic particles and shape the part. The Wire EDM process literally melts away dust and pieces of metal two microns or smaller (to get technical, that’s super small…)

What have we procured to add Wire EDM to our arsenal of manufacturing capabilities?

We’re pleased to introduce the Mitsubishi MV1200-S Advance M800. Welcome to the fam!

As mentioned, the main uses for this machine will be to manufacture tooling and fixtures that require incredibly tight tolerances, but each day we find a new way to use this dynamic machine to help improve our efficiencies and shop throughput.

Benefits of our new Wire EDM machine are:

  • Lights off manufacturing (it can run overnight unmanned – improving turnaround times, and overall job efficiencies).
  • Minimal burrs to limit FOD (Foreign Object Debris… the “F” word in the aerospace industry).
  • Challenging designs that cannot be met using conventional machining.
  • The mobilization of being able to manufacture small parts that we were unable to offer previously.
  • Highly accurate and demanding cutting applications.

On the surface, the Wire EDM process is quite simple: an electrical current passes between an electrode and a workpiece separated by dielectric liquid. The dielectric fluid acts as an electrical insulator unless enough voltage is applied to bring it to its ionization point, when it becomes an electrical conductor. The resulting spark discharge erodes the workpiece to form a desired final shape (source: engineering.com – for those who wish to learn more).

About the MV1200-S Advance M800:

  • The latest advancement to the MV series is the revolutionary Mitsubishi M800 CNC control with intuitive operation using a cell phone like 19-inch touch-screen on an ergonomic tilt/swivel mounting system.
  • New software functions help operators with a setup checklist and enhanced maintenance screens to keep track of operations. All new common shape macros reduce programming time by as much as 88%.
  • The new Advance Pendant Box uses a thin tapered design with a 3.5-inch LCD touch screen to provide our operators with more functionality at the machine, reducing setup time.

In short, we’re “wired” because of this new machine! If you’d like to talk shop, so would we! Connect with us anytime by emailing us at info@mushield.com or by calling 603.666.4433.
