Quick change tool-holder Coventry Toolholders
• Centre drill, drill tap, chamfer.
This simple sequence of operations is used
thousands of times a day on turret mills around
the world. Simple though it may be, it requires 3
toolchanges, often taking longer than the actual
cutting times. Easychange will enable this wasted
time to be reduced to a fraction of that required
with conventional equipment.
Easychange is simple, accurate and robust, and
has the added advantage of allowing tools to be
pre-set to length, thus increasing productivity on
repeat operations. The short overhang of Easy-
change means no significant loss of capacity or
performance. Tool changes are executed by hand,
(often changes can be accomplished one handed)
and no spanner or key is required, as Easychange
locks fully automatically the moment the
toolholder is loaded.
The release action is such, that very little clearance
is needed between the tool and the workpiece
when changing tools. This greatly reduces the
amount of time spent winding the table clear, or
retracting the quill.
Easychange requires no special installation, it
simply fits into the machine spindle using the
existing drawbar, and as it can be left in situ and
used for almost any milling or drilling task, it
protects the machine spindle from the wear and
tear associated with constant toolchanging.
