Atlanta EDM introduces our latest addition, the Charmilles 440cc which uses the CC generator to improve machining speed while preserving the surface integrity of the machined material. The cutting speed in tool steel can reach a high of 37 square inches an hour.

The CC generator is a digital generator based on high-tech components. From roughing to finishing, the CC generator is 'zero voltage' to protect parts against electrolytic effects. As a result, users of the 240cc/440cc receive anti-electrolysis in rough and skim cutting. The cutting speed increases apply even when a tall part is being cut, up to 15.75".

The key to the 440cc's speed is Charmilles' new spark design. The maximum ignition voltage has been increased by 25%. The maximum amplitude has been tripled from 400 amp. to 1,200 amp.

The quality of the surface finish is another advantage of these machines. The machine achieves finer surface finishes with fewer skim cuts. An important application for us is our medical industry customer base. Our customers use a lot of titanium on titanium alloys that frequently are placed into the human body as artificial parts. The CC generator prevents oxidation on the titanium and maintains surface integrity free of brass and zinc materials originating during the cutting process from the wire electrode. In carbide applications the machine minimizes cobalt depletion, the effect of which is to hold tungsten together. This insures a higher bearing capacity of punches or dies. The new generator also performs well in cutting PCD (poly crystalline diamond) form tools, said the spokesperson.

The Taper-Expert is also available on this machine.This feature makes it possible to cut very high-precision angles, up to 30°. An accurate taper is especially important for moldmakers.
