Clamping Surface Designs

Schlenker clamping surface designs are developed and manufactured to meet a wide range of technical requirements and application scenarios. Their geometry and surface characteristics allow the clamping system to be adapted to different machining tasks, ensuring reliable function and consistent performance under varying operating conditions.

Smooth

Clamping Surface Designs

  • Standard draw-in collet
Draw In Collets – Smooth

Grooved

Clamping Surface Designs

  • With additional grooves
Draw In Collets – Grooved

Axial & Radial Grooves

Clamping Surface Designs

  • Higher clamping force compared to the grooved standard collet due to the additional axial grooves
Draw In Collets – Axial and Radial Grooves

Supergrip

Clamping Surface Designs

  • Highest clamping force at the same clamping pressure of the machine due to very closely spaced axial grooves
Draw In Collets – Supergrip

Carbide Coating

Clamping Surface Designs

  • Carbide coating possible for all shapes
  • Higher coefficient of friction than a standard collet
  • Higher clamping force
  • Repeated / afterward coating possible

Extended Clamping Length

Clamping Surface Designs

  • Can be used for long workpieces with multiple grooves
  • Greater wraparound of the workpiece circumference provides higher clamping force
  • More stable clamping for long workpieces
Draw In Collets – Extended Clamping Length

Shortened Clamping Length

Clamping Surface Designs

  • Application for workpieces whose geometry behind the clamping diameter shouldn’t be damaged
  • Used for short workpieces so the ejector can be positioned closer to the clamping diameter
