The MACH-1 System uses a special drawbar assembly that
has a patentedą tool holder locking mechanism. The mechanism uses a 600 lb.
preset die spring coupled with a hardened and ground ball coupling. The
design ensures the same forces are exerted with every tool change and
provides maximum repeatability and reliability.
The special drawbar assembly replaces your existing
machine's drawbar and installs directly into the R-8 spindle. Tool changes
are accomplished by pushing back on the quill handle. This action uses the
mechanical advantage of the rack and pinion (quill and quill handle) to
release the balls in the coupling. A 1/4" stroke is all it takes to change
tools.
The MACH-1 System is maintenance free. No parts rotate
when you change collets or tool holders. It doesn't need air, lubrication,
nor any other scheduled maintenance.
