Fitting the chuck on the machine spindle
An adapter ange or a shank is used to install the chuck on the machine. The chuck is tted
on the adapter ange or shank once tting has occurred on the machine spindle. Consult the
drawing or the dimensions table on the right for the connection sizes.
Using the adapter ange or shank to install the chuck
Attach the chuck on the adapter ange or shank. Carefully tighten all the screws connecting
the chuck with the ange/shank. Fit a dial gauge on the external diameter of the chuck body.
Use a plastic-faced hammer to set the concentricity and then firmly tighten the fastening
screws between ange/shank and chuck.
Installing the clamping jaws
DO NOTE. The clamping jaws are numbered (1, 2, 3). They are only to be tted in the slideway
with identical numbers.
Maintenance
The jaws, spirals and guides are to be regularly cleaned and greased. Machine oil or WD40,
which also ensure smooth running, are suitable for using on measuring machines.
