2. Test procedure (axial and radial run-

out)

Important: Only clamp and test the chuck in the

attached condition

2.1 Fit the chuck perfectly according to details in section

1 and only clamp and test it in the attached conditi-
on.

2.2 Use thick-walled test rings for measuring hardened,

precision cylindrical taper check gages and to pre-
vent deformation.

2.3 Use tapered cylindrical tapered check gages with

diameters according to DIN 6386.

2.4 Ensure that written key tensioning torques are follo-

wed.

2.5 The test procedure is also valid for Duro manual

clamping chucks with turned soft capping jaws.

2.6 Values given in the table assume a perfectly running

machine spindle and a properly adjusted chuck.

2.7 Checking axial and radial runout accuracy with reversible top jaws (UB) or one-piece reversible jaws EB

Concerning 2.4: Key tensioning torque for control
and wearing axial and radial runout:
