Changing
tools on a machine tool is often a long and difficult procedure. First the
machinist must uncouple the tool holder. This usually involves either a drawbolt
or keeper key. Then he must dislodge the tool holder, which usually involves
a hammer. The machinist must next remove the tool holder and replace it with
the next tool and recouple it. This procedure can easily take five minutes,
or more. Because changing tools can be a hassle there are quite often times
that an improper or inappropriate tool is used.
With a quick change tooling system the time required to change tools can be
reduced to seconds. Typically a locking nut or collar is loosened, the tool
adapter is removed and replaced with another tool adapter, and the nut is
retightened. Use of a quick change tooling system will drastically increase
efficiency by reducing the time to change tools, as well as make it easy to
use the proper tool for the job. A 30% increase in productivity is not an
uncommon occurrence.
The use of a quick
change tooling system has some, not insignificant, side benefits. The machinist
no longer has to pound on the spindle to dislodge the tool. By not having
to beat on the spindle with a hammer, the life and accuracy of the spindle
bearings is greatly increased. In most quick change tooling systems a master
holder is inserted into the machine spindle, and is not removed. All the tool
changes involve removing and inserting adapters into the master holder. This
eliminates wear on the machine tool spindle due to tool changes.
