CNC automatic lathes


The Advantages

The ST-38 from STAR Micronics further develops the series of the complex KNC-32 and SV-32 machines.

A machine for highly complex parts, yet easy to program in the usual way with the FANUC control system with machining possibilities for parts up to a workpiece diameter of 38 mm.

The 3 turrets allow for almost limitless machining flexibility. The ST-38 therefore enables the machining of turned parts which require up to 60 tools.

  • FANUC 31i-B5 control system
  • C-axis control as standard on main and sub spindle
  • completely independent backworking
  • movable control panel
  • two tool carriers for simultaneous machining on the front side
  • additional longitudinal axis on the tool carrier
  • drive power turret 4.0 kW
  • three independent tool systems
