Torque with which the clamping device is actuated, e.g. with a torque wrench.

Workpiece end-stop within the chuck.

Occurs at rotation, with a jaw chuck for example. The jaws are forced outward and the clamping force decreases. TOPlus and SPANNTOP on the other hand enclose the clamping  head with their chuck body and therefore are virtually loss-free.

Defined position of the clamping element, in which the nominal diameter is clamped, if the workpiece does not have any tolerance deviation.

Force with which the workpiece is radially clamped by the clamping device.

Front nose extension of the clamping head that projects beyond the face of the chuck.

Workpiece that is clamped on a finish-machined surface.

Workpiece that is clamped on an unmachined surface.

Indicates the total range of the clamping diameters that can be covered with the respective size of the clamping device. Multiple clamping elements are required to use the entire range.

Additional clamping distance of the clamping device for spanning negative workpiece tolerances.

Deviation [difference between the greatest and lowest dial gauge indication] of a test piece at rotation relative to the reference axis.

Force, with which the clamping device is actuated, e.g. by a clamping cylinder.

Dimensions of the front edge of the drawtube inside / outside of the machine spindle to the bolt-on surface of the clamping device on the spindle.

The force with which the workpiece is clamped in the clamping device.

Round geometry, e.g. clamping head outer geometry SPANNTOP.

Distance of the clamping element from the theoretical clamping position to the release position, in which the workpiece can be removed or the clamping element can be changed.

Deviation that can be measured as the spread of two successive assembly and disassembly processes. It cannot be corrected manually, it is intrinsic.

Resistance of the clamping device against plastic deformation due to force or a moment.

Hexagonal geography e.g. clamping head outer geometry TOPlus.

Clamping range, in which the workpiece tolerance should be.

Standardized interface between clamping device and machine spindle.

Positioning of the clamping element in the clamping device.

Procedure for producing high-quality rubber-steel combinations. It is used with our clamping heads, for example.
