Barrel tools

  • Enables a greater ap step-over maintaining the same theoretical scallop height
  • Delivers better production efficiency rates from shorter machining times with enhanced surface quality
  • Cycle time savings of up to 90%
  • Increased tool life while simultaneously reducing the number of tools required
  • Spindle growth and machine position tolerance due to thermal properties are compensated with the large tool radius
  • Lower set-up costs
  • Excellent process reliability
  • Reduces / eliminates the need for post-milling processes such as finishing and polishing
  • Reduces the effects of heat transfer that can lead to thermal deformation of the component
  • Production flexibility with the tool’s capability of face machining and ball-nose cutting





SGS Barrel tool design

Barrel tools are a variation of a taper ball-nose tool. However, the straight taper is replaced with a large tangential radius, (Ø50mm to Ø1500mm).

• Barrel tools are designed to replace inefficient ball-nose scanning
• They are highly efficient at finishing & semi-finishing profiling
• Main application areas are profiling and pocket milling
• They are especially suited to machining deep pockets and hard-to-reach areas without using expensive long-reach tools
• Their versatility also allows them to machine faces and blends with one tool

Components include:

  • femoral knees and trauma plates,
  • blisks, discs and blades
  • turbine blades
  • deep cavities
  • complex shapes
