Due to the high-precision manufacture of Königdorn® mandrels, they can also be used as measuring device. The example on the right shows the measuring of a Klingelnberg gear on a taper drive which is clamped at 2 locations and can thus achieve a run-out accuracy of up to 0.002 mm. The chuck is open toward the back in order to let the air cushion escape when positioning the workpiece. The clamping force is initiated radially by hand.

Königdorn® mandrel for measuring an external gear on an automatic tooth profile measuring machine (middle). The mandrel is flanged on the machine and is clamped automatically by means of a pneumatic cylinder. Automatic workpiece loading is possible. Run-out accuracy: 0.003 mm.

Königdorn® mandrel for measuring the external gear of a tooth profile measuring machine. The mandrel is located between centers in the measuring machine.

Clamping is performed axially by hand. The mandrel is made of light metal, resulting in great weight savings. Clamping bushings and centers are made of highly wear-resistant tool steel. Run-out accuracy: 0.003 mm.

Königdorn® chucks on testing devices and measuring machines
Königdorn® measuring device with internal helical gear ground into the clamping bushing.

The workpiece is measured on the radial and flat surfaces. The clamping force is initiated radially by hand.

Use of a Königdorn® chuck as base chuck on a tooth profile measuring machine. Centering points for measuring gears and various accessories are clamped into this chuck on mandrels between centers. This base chuck has a run-out accuracy of 0.001-0.002 mm and is clamped manually with a lever. This clamping mechanism guarantees simple and very fast operation.

Königdorn® measuring device for mounting heavy workpieces with 2 clamping chambers in the mandrel on a clamping surface.

The mandrel rests in a revolving ball cage which permits a run-out accuracy of 0.005 mm.

The clamping force is initiated axially by hand. Measuring of all machined radial and flat surfaces is possible.
