Lean automation

Lean automation describes a flexible and affordable method of automated machine loading by using already available functions of the machine tool intelligently. The raw and finished parts tray is located within the travel area of the machine. With the help of a gripper with spindle interface, workpiece handling can thus take place within the machine workspace. A clamping station facilitates the manual changeover of raw and finished parts as well as clamping devices.

Advantages of lean automation:

  • Low acquisition costs.
  • No additional knowledge required for operation.
  • No additional space required in front of the machine.
  • Dual working is easily possible.

Workpiece automation

In workpiece automation, raw parts are taken out of an external storage unit, and loaded into the machine tool's clamping device with the help of a handling device. After machining, the finished and semi-finished part can be removed from the clamping device and stored in the storage unit.

Advantages of workpiece automation:

  • Long unmanned machine running times can be achieved.
  • Fast loading and unloading times thanks to automation that is perfectly adapted to the workpiece and the process.
  • Optimal for interlinked process steps.
  • Can also be used in unfavorable ambient conditions.

Pallet automation

In pallet automation, workpieces are set up outside the machine in the clamping device. This is located on a pallet, and the complete pallet (including clamping device and clamped workpiece) are then loaded into the clamping station in the machine tool. The complete pallet with the workpiece is removed from the machine after machining. The workpieces are loaded into and unloaded from the clamping device outside the machine, something which can be done manually or automatically.

Advantages of pallet automation:

  • Different clamping concepts can be implemented, also suitable for small series.
  • Enables clamping of complex workpieces.
  • Also suitable for automation of heavy workpieces.
  • For machining operations with high requirements on accuracy of the clamping situation.

Workpiece & pallet automation

R-C2 is an example of an automation solution that combines features of both workpiece and pallet automation. The workpiece lying in the storage rack is gripped with the R-C2 and is clamped at the same time. The clamping force block with the clamped workpiece is then loaded into the quick-change pallet system of the machine like a pallet. After machining, the R-C2 with the clamped workpiece are removed from the machine. The workpiece can now be set up again, clamped and loaded for processing the second side. After production, the R-C2 with the workpiece is removed again and the finish-machined workpiece is located.

Advantages of workpiece & pallet automation:

  • High level of flexibility.
  • Less set-up effort.
  • 6-sided machining without manual intervention while maintaining high accuracy.

Flexible Manufacturing System (FFS/FMS)

Flexible manufacturing systems are multi-machine systems for machining workpieces. The individual machine tools are connected to each other via a connected transport and storage system to enable an automated material flow. In addition to the machine tools, there are corresponding transfer stations, where the raw parts are prepared, the clamping devices are loaded and unloaded, and the finished parts are deposited.

Advantages of flexible manufacturing systems:

  • Perfect utilization of the machine, increased spindle running time.
  • Large number of available pallet storage spaces.
  • Perfect organization and logistics of production through stockpiling of raw parts, clamping devices and tools​.
  • High flexibility in the selection of the production sequence.
