Summary

The Kellenberger SP65 is a CNC turning center designed for high-precision two-axis and multi-tasking machining operations. It achieves surface finishes of 0.2 μm or better and supports complex part production in a single setup, enabled by advanced spindle, control, and axis feedback technologies. Key features include dynamic spindle balancing, integrated direct-drive motor, and a robust FANUC 31i control for precision and minimal human intervention.
