CNC Swiss Type Lathe

SS-51RB/51RBY

Sliding-head (Swiss-type) CNC Lathes

SELICA SS-51RB / SS-51RBY Series is designed for high-precision machining of bar stock up to Ø51 mm. Featuring main and sub-spindles, synchronized machining, and flexible live tooling configurations, it efficiently performs turning, milling, drilling, tapping, and back machining in a single setup. The SS-51RBY further expands machining capability with an additional Y-axis on the sub-spindle, providing greater flexibility for complex multi-axis operations. Ideal for larger and more demanding precision components, the series delivers excellent rigidity, productivity, and machining accuracy.
