AgieCharmilles FORM S 350

Easily - and with extreme repeatability - deliver the perfect machining accuracy your ICT and automotive customers demand. Meeting their stringent quality requirements for electronic components is a snap, thanks to the high-precision FORM S 350’s state-of the art design with onboard power generation system, accuracy-enhancing stability and thermostabilization, and productivity-boosting machining quality.


The AgieCharmilles FORM S 350: Your miniaturization solution

The AgieCharmilles  FORM S 350 sinker spark erosion machines are fitted with an Intelligent Speed Power Generator (ISPG) which, using patented technologies, establishes new standards in surface quality, material removal and accuracy of form. Electrode wear is reduced in all machining operations, from roughing to finishing, with copper or graphite electrodes. Productivity shows an average increase of 30 percent, and can even reach 100 percent for pre-milled forms. Even in the presence of deep, narrow cavities, with poor flushing conditions, a 50 percent increase in erosion speed can be obtained with no increase in electrode wear.
