CNC Machining Machining with a very thin Brass Wire.   Finished tolerance to +/- 0.0001  EDM - Electrical Discharge Machining  Wire EDM is "Electrical Discharge Machining". This is a process that  removes electrically conductive material through an “electrical  sparking” action. This is accomplished by rapidly recurring,  controlled electrical discharges between the work piece and a  moving brass wire. The discharges occur millions of time per  second.  This technology can be likened to a vertical band saw. The difference is that, unlike a band saw,  wire EDM is cutting with a continuously spooling “blade”. The blade is in the form of a brass wire  that can be as thin as 0.002” in diameter. And, unlike a band saw, there is no pressure exerted on  the wire or on the work piece. The wire never touches the work. Sparking  occurs across the 0.0002” - 0.0003” gap that is always present between the  wire and the work piece. So, there is no need to use heavy clamps or straps to  hold the part in place. Most times, “crazy” glue is used to hold parts for cutting.  Wire EDM applications can be characterized as producing extremely exacting  tolerances that would, otherwise, be very difficult or impossible to manufacture.  Since there are no cutting tools to wear out, this technology produces the same  high precision parts time after time.  CNC Wire EDM Equipment List     5 - Wire CNC EDM (FANUC) (14.5 x 19.5 x 16" Under Wire)      (Z Axis = 16”) 1 - EDM "Sinker", (AGIE MONDO 20) CNC, (AGIE MONDO 20) 1 - EDM Hole Master ("Hole Popper")     Products ITAR Registration  Code: M27100  • LIGI TOOL & ENGINEERING, INC. © 2010 All rights reserved. 3220 SW 15th Street Deerfield Beach, FL 33442 Phone: 954-332-2921 Fax: 954-332-2955 e-mail: info@ligi.com
