SB-20R Type G Long-Turn Automat Platform

The Star SB-20R Type G is a CNC sliding headstock automatic lathe optimized for the production of long, slender precision components where guide bush support prevents workpiece deflection during machining. The sliding headstock principle feeds the bar stock through a guide bush positioned close to the cutting tools, maintaining rigidity and dimensional accuracy regardless of the part's length-to-diameter ratio.

The SB-20R series addresses production requirements in the medical implant sector (bone screws, dental implants), electrical connector industry (precision pins, contacts), and automotive electronics (sensor housings, valve components) where long thin parts with tight tolerances and excellent surface finishes are standard specifications.

Star Micronics' multi-axis architecture enables simultaneous front and back machining operations, producing complete parts from bar stock without secondary operations. The Type G designation indicates the latest generation kinematic layout with optimized axis arrangement for complex part geometries. Bar feeders connect directly to the machine's headstock for continuous unmanned production across multiple shifts.
