ST-38
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
Kinematics & Tools
- 3 turrets each with 10 tools for excellent power-driven machining flexibility
- 30 + α power-driven tools for turning, drilling, cross drilling and backworking
- 12 axes
