SS-20A/20AS
The SELICA SS-20A and SS-20AS deliver high-precision machining for small-to-medium diameter parts. Featuring a rigid design and advanced controls, the SS-20AS adds a sub-spindle for complete machining in one setup, boosting productivity and accuracy.
Tooling Capacity
The SS-20A / SS-20AS is equipped with a versatile tooling layout for efficient multi-operation machining:
External Tool Holders: 8 positions for turning and profiling operations.
Inner Tool Holders: 5 positions for boring, threading, and internal machining.
Side Drilling Devices: 4 positions for cross drilling, tapping, and milling operations.
This configuration enables flexible part processing, reduced setup time, and consistent high-precision performance.

This configuration enables flexible part processing, reduced setup time, and consistent high-precision performance.
20A Tooling layout
SS-20A is equipped with a single spindle and a flexible guide bush system, allowing operators to choose between guide bush and non-guide bush holders depending on the application. This adaptability provides optimal support for long and slender workpieces when using the guide bush, or reduced material waste when operating without it. The system accommodates a minimum rest bar length of 50 mm, enabling efficient machining while minimizing raw material remnants.
20AS Tooling layout
The SS-20AS is equipped with both a main spindle (Z1 axis) and a sub-spindle (B axis), enabling complete front and back machining in a single setup. Its rigid gang type tooling layout supports multiple turning, drilling, and milling tools, arranged for optimal accessibility and minimal tool change time.
