3.1 OPERATING THE POWER DRAWBAR
The Power Drawbar is designed to provide more than sufficient
tool holding force to resist regular cutting loads. Machining
practices outside of these situations may result in tool holder pull-
out.
While operating the machine, avoid the following conditions:
l High chatter machining
l High cutter engagement (chip load) combined with high
helix angle cutter geometries
3.1.1 Change Tools with the Power Drawbar
WARNING! Ejection Hazard: Wait until the spindle is
completely stopped before pressing the Release Tool
button. Never press the Release Tool button while the
spindle is turning. Tooling can become a dangerous
projectile if it's released from a turning spindle.
1. With one hand on the Tormach Tooling System® (TTS®) tool
holder installed in the spindle, press and hold the Release
Tool button.
The Power Drawbar activates and releases the tool holder in
the spindle. Remove the tool from the spindle.
CAUTION! Pinch Hazard: Keep fingers clear of the
Tormach Tooling System® (TTS®) collet when
changing tools. Never put your fingers into an
unclamped Tormach Tooling System® (TTS®) collet.
If your fingers are in the Tormach Tooling System®
(TTS®) collet as it closes, it can crush or pinch your
fingers.
2. Insert a new tool holder.
3. Let go of the Release Tool button.
The Power Drawbar reverts to clamp mode and secures the
tool in the spindle.
NOTE: In the event of an air pressure loss, the
power drawbar reverts to clamp mode.
While the Power Drawbar is in clamp mode, make sure that
there's always a tool in the collet. Retracting the Power
Drawbar to clamp mode with no tool in the collet will
eventually fatigue the collet, and could shorten its service
life.
