The AgieCharmilles cut 200 Sp speed edition wire EDM from GF Machining Solutions provides fast spark-to-spark wire threading, energy efficiency and high productivity when cutting parts of variable heights. It also offers versatility through its ability to reliably hold micron-level tolerances in both light and heavy parts. The machine’s digital CC generator can provide surface finishes as fine as Ra 0.1 micron, and an optional power module can boost cutting speed to 400 mm2/min. with an adapted wire. To ensure accuracy and speed as well as prevent wire breakage when machining parts with varying heights, the Power Expert smart module continuously calculates part thickness, checking injection pressure and adjusting machine power accordingly.

The EDM accommodates wire diameters ranging from 0.33 to 0.07 mm and can handle part tapers ranging to 45 degrees, regardless of part thickness. The machine has a drop door to the work area to ease loading of workpieces. Its small footprint leaves ample room for X-, Y-, Z-, U- and V-axis travels measuring 350 × 220 × 220 × 350 × 220 mm. To obtain high positioning precision, the axes are fitted with a linear glass scale with absolute encoding at a resolution of 50 nm. An optional touch probe enables the user to inspect a finished part before its removal from the worktable, eliminating the need for part inspection with a CMM.
