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:
