Mounting of the Chuck to the Machine Spindle
Note for a vertically suspended machine spindle
In the case of a vertically suspended machine spindle, it must be
ensured that the piston (2) has a stop in the chuck flange (1). This
prevents the chuck body of the clamping chuck from being pulled
by the dead weight.from the piston (2) during the assembly / dis-
assembly.

Inspection of the spindle nose for mounting the chuck flange
To achieve high true running of the chuck, the machine side must
be aligned before mounting the flange. Therefore check the receiv-
ing surface at the spindle for concentricity and runout with a dial
indicator.
maximum run-out error of 0.005 mm on the centring mount and
a maximum run-out error of 0.005 mm on the contact surfaces
must be ensured.Also, the end face of the spindle must be
checked for evenness with a straightedge.
It must also be ensured that the surface of the end face is cham-
fered and clean at the bores.
