CNC Swiss Type Lathe

SS-20RB/RBY

Sliding-head (Swiss-type) CNC Lathes

SELICA SS-20RB / SS-20RBY Series is a high-performance Swiss-type CNC lathe engineered for precision machining of bar stock up to Ø20 mm. Featuring main and sub-spindles, high-speed live tooling, and guide bushing or rotary guide bushing configurations, it delivers exceptional flexibility for both long and short workpieces. The SS-20RBY features dual Y-axis control, enabling simultaneous front and back multi-axis machining for greater flexibility and reduced cycle times. Designed for demanding production environments, the series performs turning, milling, drilling, tapping, threading, and back machining in a single setup with outstanding accuracy and productivity.
