CNC Swiss Type Lathe SS-20AB/AST

SS-20AB-Tooling

high-precision Swiss-type CNC lathes designed for small-to-medium diameter machining up to Ø20 mm. Both models feature a rigid gang type tooling system with capacity for 8 external tools, 5 internal tools, and 4 cross drilling devices, plus 4 sub-spindle face tools for complete part machining in one setup.

SS-20AB with 3 position eccentric rotary tool holder

The SS-20AB is equipped with a 3-position eccentric rotary tool holder, providing greater flexibility for drilling, tapping, and milling operations. This design allows multiple live tools to be mounted in a compact arrangement, enabling faster tool changes, reduced setup time, and efficient machining of complex features.
