23340.0612 - Centering Clamping Mandrels
cylindrical

The centering clamping mandrels, cylindrical are ideal for use in fixture construction. They enable workpieces to be clamped with a hole on their inside diameter and therefore without interfering clamping edges. The centering clamping mandrels can be mounted on grid and fixture plates, for example, by pressing them into bores or screwing them into threads.

They enable exact positioning, offer precise repeat accuracy and achieve high holding forces when clamping parts with holes. The centring clamping mandrels offer the possibility of fixing complex workpieces without external clamping elements to enable these components to be machined on 5 sides.

The centering clamping mandrels, cylindrical have the following characteristics:

  • Clamping stroke max. 0.7 mm
  • Two versions - for press-in or screw-in
  • Made of stainless steel or free-cutting steel
  • Clamping body can be machined very easily (for adaptation to bore diameter)

This article 23340.0612 - Centering Clamping Mandrels cylindrical / screwable (d1: 12 mm) is one variant of the article group Centering Clamping Mandrels cylindrical (EH 23340.)
