Type 611 Mandrel (Dead Length)

For special applications, we recommend an deadlength clamping solution i.e. the bushing only move radially. A  part with a stop or shoulder could be an application for this, in order to avoid the reduction of the clamping length. Typically used on a sub spindle, where the work-piece is picked up from the main spindle for secondary machining, prohibiting any pulling effect between spindles.

The clamping bushing on this mandrel type is fixed axially and has no movement during clamping. The application for this mandrel is for relative short parts, or easily deformed parts. The minimum clamping-ø is 25 mm. Clamping is actuated by the draw tube.
