The SV-38R combines the fast processing ability of a traditional platen type sliding head lathe with the flexibility of a turret machine. The main spindle benefits from a gang type tool post and an 10 station turret to enable simultaneous machining operations. The turret includes an independent Z3 axis, this axis allows two different features to be machined simultaneously (Z1 + Z3) using Star’s “super-position” control mode.

Fanuc’s high specification 31i-B5 control delivers full five axis capability enabling highly complex components to be processed. The B-axis tool holders on the turret enable angular features to be machined on both the main and sub-spindle.

The powerful sub-spindle with independent 8 station platen increases overlapped machining possibilities. The Y2 axis on the sub-spindle platen allows both cross working and front facing power tools to be mounted in any station.

The flexibility of the STAR SV-38R is further enhanced by its ability to switch between guide bush mode (Swiss type) and non-guide bush mode.


  • Standard machining diameter 38mm (42mm in NGB mode)
  • Z1 Stroke of 350mm in Swiss mode, 95mm in non-guide bush mode
  • Z3 axis enables SUPER-POSITION control for increased overlap
  • Switchable between guide bush and non-guide bush modes
  • Main spindle speed 7,000 rpm, sub-spindle speed 7,000 rpm
  • Built-in type main and sub-spindle motors for improved indexing accuracy
  • Programmable B axis for angular machining
  • STAR MOTION CONTROL to minimize idle time
  • 8 Station sub-spindle platen for maximum overlapping
