CNC underfloor aggregate for processing on the underside of the panel

The SOTTO FUNCTION LINE is an innovative underfloor aggregate that has been specially developed for processing workpieces on the underside of CNC machines. The CNC aggregate is clamped into the spindle of the machine and diverts the tool output so that the tool plunges into the material from below.

Advantages of underfloor machining

  • Time saving: Processing both sides of the workpiece panels in a single operation is possible without manual turning.
  • Increased precision: Inaccuracies caused by manual turning of the plates are eliminated.
  • Faster cycle times: Processing time and labor requirements are reduced.

Machining options on the underside of a material sheet

The underfloor aggregate enables a variety of drilling and milling operations on the underside of the workpiece, which can be carried out with a wide range of CNC tools. Blades and tools for marking drilling patterns can also be clamped in the aggregate's tool holder. The selection of the appropriate tool for underside machining depends on the type of material, the panel thickness and the specific application.

Processing from below for panels with thickness variations

For machining operations such as milling radii, chamfers and profiles on workpieces with varying thicknesses, the underfloor aggregate is equipped with a tracing device. This tracing device ensures that consistent and constant machining depths are also achieved on the underside of the workpiece.

Possible applications of the underfloor aggregate

Thanks to the possibility of using a wide variety of tools in the tool holder, numerous different applications can be carried out:

  • Windows: Underfloor milling of sealing grooves
  • Doors: Underfloor drilling (standard and cup hinge)
  • Furniture + kitchens: Cup hinge drilling or milling for hinges


  • Marking of drilling patterns
  • Milling for fingerprint
  • Milling of worktop connectors
  • Milling of handle foils
  • Milling of cup hinges and cup hinge hinges
  • Drilling of handle foils
  • Dowel holes
  • Milling of hook-in connectors
  • Milling of door rosettes
  • Flush milling of rosettes
  • Chamfering
  • Traced radius processing
  • Profile processing
