Accuracy is key in the design of the Robofil 2050TW wire EDM. The machine is thermostablized, and precision glass scales measure down to 0.0019685-in. (0.05 mm) increments. The 2050TW uses two wire spools handling 0.0008 (0.02 mm) to 0.012-in.-diameter (0.33 mm) wire, and its CC generator produces finishes as fine as 0.0019685-in. (0.05 mm) Ra in carbide.
