The CNC Eight-Spindle Automatic from Schütte
With the new A 36 PC CNC Multi-Spindle Automatic Schütte supplements its successful "PC" series by a fully CNC-controlled eight-spindle bar automatic. The new, fully CNC-controlled eight-spindle automatic that Schütte introduces to the market represents an extremely flexible manufacturing system. This high-yield, quickly retooled, flexible, ultra-precision manufacturing tool offers extensive machining operations on bar material of up to 36 mm diameter, the like of which has not been seen before on eight-spindle automatics. The utilisation of up to 20 CNC tool slides, 12 possible CNC compound slides, or 30 controllable slide axes and up to 12 spindle axes, shows what the new Schütte eightspindle auto is really made of.

The control system of the electrical drives (spindle drives and spindle drum index) and the hydraulic drives (endworking and cross slides) are digitally controlled. The newly developed Hydraulic Controller AH2000 from Beckhoff controls the hydraulic axes. This strictly separates the target default values in the central Industrial PC from the individual feed rate controls.

The control system has the following characteristics:
- The target default values are transmitted to the individual
  decentralised hydraulic control elements via a Profibus network.
- The hydraulic modules now control the various feed rates.
- The control modules are combined with a direct position feedback
  system with a resolution of < 0.1 µm.
- The high clock pulse of the control modules is independent of the
  network bus pulse rate and guarantees a more precise path control
  and increased positioning accuracy, acceleration and dynamic.
