Since water is not the insulator that dielectric oil can be, ionization occurs rapidly. M Schumacher. • both the ram and wire-type of EDM are detailed • the subsystems of both types are explained • hole drilling EDM’s are shown • computer numerically controlled, or CNC, EDM applications and safety issues are addressed. The following processes are discussed: ultra-precision milling, thin-wire EDM, die-sinking micro-EDM and diamond turning. In Electrical-Discharge Machining (EDM) Wire Cut is usually performed in a bath of water. It specializes in the machining, cutting and bending of different materials, as well as finishing work and custom projects. The Sodick Wire EDM range features rigid linear motors, maximizing cutting performance and giving you the part accuracy you need to be the envy of your competition. Figure 1: Coated wires machine faster than uncoated brass. Home - Manufacturing Engineering Source Guide Manufacturing Engineering Source Guide. The Machine Fundamentals Course will introduce and instruct the student in the functions, setups and operational principles of the current series 64-bit PC based Mitsubishi Wire EDM machine. Tool & Die, Inc. Electrical discharges cut the w/p according to desired shape. Electrical discharge machining wire cutting (EDM-WC) is a thermal mass-reducing process that uses a continuously moving wire to remove material. The EDM process produces a cavity slightly larger than the electrode because of the overcut. Level Monitors and Controls.
