AgieCharmilles FORM 400

The FORM 400 range incorporates new online help to allow the operator to find relevant information as quickly as possible. This occurs via simplified access to help menus, by having a clearly organized navigation interface, that is more user-friendly and easy to grasp, and including search by key words or user index. Machining examples are produced as hard copy, presented in a succinct manner.

The AgieCharmilles FORM range: high flexibility for simple to complex tasks


The AgieCharmilles FORM 400 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.
