BACK-END MACHINING CAPABILITY
All series could select the optional sub-spindle to machine the back-end after receiving the part. Ø 51 mm bar capacity adopts 8" chuck featuring ejector, which allow the finished parts can smoothly drop on parts catcher successfully. All the processes from loading the parts can all be done in one machine without a pause.

Automatic part transfer of work piece from main spindle to sub-spindle saves manpower and cycle time, while reducing accuracy lost, which will occur if manually handling the part from machine to machine.
The sub-spindle configuration is also ideal for machining long work pieces such as small diameter shafts. Both ends of the work piece can be supported by the main and sub spindles, allowing the middle section(s) to be accurately machined.

Sub-spindle can be controlled by Cs-axis to achieve back-end machining, which allows conveniently operating, fast positioning, and higher accuracy.
Z2-axis adopts high performance linear guide way design, which is driven by FANUC direct driven motor, provides the optimal axial accuracy.
