Over Spindle Quick Change Drilling Chucks for drilling, chamfering and counterboring tools.
These over spindle quick change drilling chucks can be fixed to the
noses of machine spindles which conform to DIN 55058. They are
located on the spindle by means of a special screw which locks the
chuck onto the spindle nose. This screw locates in a tapped hole
in the spindle, and the inner sleeve of the chuck has six holes
which accomodate the positional tolerance of the tapped hole in
the spindle and ensure free of play positioning.
These drilling chucks, combined with the Bilz SSM adjustable lock
nuts provide a rapid and effective quick change system for adjustable
adaptors and toolholders with DIN 6327 trapezoidal shanks.
They can be used on multi-spindle machines, transfer lines and
special purpose machines.
Tools can be changed quickly and easily, the tools are automatically
locked into the unit on location of the tool into the spindle.
The tools are released by pulling forward the outer sleeve of the
chuck and removing the tool from the spindle.
This quick change system ensures the safe, play-free location of
tools in the spindle. Tool change is carried out when the spindle is
stopped and the tools are easily handled even in restricted locations
on equipment such as multi-spindle heads.
