CHUCKING C-27
Although the chuck jaw stroke end detecting switches can detect whether the
workpiece is gripped by the chuck within an appropriate master jaw stroke, they cannot
detect chucking errors in the chucking face direction; such as not holding on the chuck
face correctly, tilting in the chuck, etc.
To detect correct holding of a workpiece in the chuck, use the optional holding
detection function.
<Other checking methods>
Some chuck manufacturers supply the chuck with a stroke mark engraved so that the master jaw
stroke can be visually checked. If using such a chuck, make sure that the stroke mark is within the
appropriate stroke range. For details, refer to the instruction manual supplied by the chuck
manufacturer. If no such information is given, consult the chuck manufacturer.
