Knuth Spark Erosion Countersinking EDM 460/60 CNC

- X, X, and Z axes travel on preloaded, zero-backlash ball screws and are driven by servo motors with high torque and high positioning accuracy (2 µm)
- glass scales for 'closed loop' operation Higher accuracy is achieved by tuning the actual values with the theoretic value of the control
- TURCITE-B coated guideways
- square quill, hardened (HRC 60)
- linear guideways of quill
- The control adjusts impulse durations and purge durations to prevent possible problem conditions (arcs, risk of burning up electrodes, etc.)
- Overlayed high-voltage can be selected to increase the surface quality for deep nests and to increase the finishing erosion capacity
- also suitable for carbide machining
- Generator has a PC-based structure for easy board replacement in case of a failure
