Measuring 100.4” x 128.7” x 101.0”, Charmilles’ (Lincolnshire, IL) ROBOFIL 640cc wire EDM has been added to company’s CC line of machines. This machine features large axis travels of X (U) 31.5” x Y (V) 21.7” x Z 19.7”. It uses CC generator to dramatically improve machining speed while preserving the surface integrity of the machined material. 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 640cc achieve the fastest cutting speed on the market plus anti-electrolysis in rough and skim cutting.
The key to the 640cc’s speed is the company’s new spark design. The maximum ignition voltage has been increased by 25 percent; and the maximum amplitude has been tripled from 400 amp. to 1,200 amp. The high quality of the surface finish is another advantage of the CC machines. Each machine achieves finer surface finishes with fewer skim cuts. The CC generator offers exceptional benefits for the medical industry, which uses a lot of titanium and 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.
