3-axis Simultaneous Turning

Efficiency and flexibility for turning and milling operations: hyperMILL® MILL-TURN Machining offers easy-to-program CAM strategies for simultaneous roughing and finishing.

Simultaneous machining further boosts the mill-turning efficiency of machines with a swivel head on the third axis. Complex workpiece geometries can be machined in a single operation by simultaneously adapting the approach angle during turning.

Simultaneous turning programmed with ease

Two special strategies for simultaneous roughing and finishing make programming both simple and reliable. Here, synchronization lines are used to control the movement of the third axis. The simultaneous movement of the third axis is calculated automatically between the synchronization lines.


  • Process complex contours in a single operation
  • Optimal tool utilization
  • Increased tool life
  • Fewer tool changes
  • Easy to program
  • For machines with a swivel head on the third axis
  • Fully checked for collisions
