The AgieCharmilles FORM 20 and AgieCharmilles FORM 30 are available with the optional GammaTEC technology to optimize machining performance for shiny surface finishing on big workpiece surfaces.

Two machines in one

Rapid and easy changing from this configuration to standard EDM gives you the advantage of having two machines in one. Notably, the Swiss-made generator and all the available features of the standard configuration make the AgieCharmilles FORM20/FORM 30 comprehensive partners in your production chain.

  • Homogeneous quality of surfaces of all shapes, including fine details
  • Possibility of fine machining even for large surfaces
  • Less time taken to achieve a "mirror polish" finish
  • In many cases, elimination of manual polishing
  • Significant reduction in electrode wear
