ADJUSTING ATC TOOL PULLSTUD CLAMP
ADJUSTING ATC TOOL PULLSTUD CLAMP
Overview
This is a step-by-step procedure for adjusting the tool pull stud clamping mechanism
Problem
On several of the ATC mills the tool holders will not release properly from the spindle taper. This is
caused by an improperly adjusted pull stud clamping mechanism located on the spindle. Follow the procedure
below to correctly adjust the tool clamp.
Procedure
1. Remove the side panel of the spindle cover from the spindle. This will give you access to the tool
clamping assembly located above the spindle cartridge. View figure 1.
2. Unplug the electrical connector from the spindle air blow through selenoid located on the left side of
the main column on the mill. This will be the only selenoid valve that has a port capped off and should
be the first valve in the solenoid pack, as illustrated in figure 2. This will prevent the spindle blow
through from interfering with the tool clamp adjustment.
3. Loosen the two small cap head screws on each side of the large end adjustment bolt located on the
bottom end of the air cylinder shaft, as illustrated in figure 3. This will allow the large center bolt to be
adjusted.
4. Insert a tool holder into the spindle while holding the tool clamp/unclamp button located on the front
right hand side of the spindle housing.
5. Release the tool clamp/unclamp button and make sure the tool holder is securely held in the spindle.
6. Turn the large end adjustment bolt located on the air cylinder shaft until the tool holder, held in the
spindle, moves at least 1/16” away from the spindle when ever the clamp/unclamp button is pressed,
but not more than 3/32” from the spindle. Refer to figure 4. After you have made the proper
adjustment the tool holder should release easily from the spindle when the clamp/ unclamp button is
depressed. There should always be a gap between the large adjustment bolt and the top of the spindle
when the clamp/unclamp button is not depressed, because the bolt remains stationary and the spindle
rotates, if there is not then you have adjusted the large bolt too far down!
7. Tighten down the two small cap head screws on each side of the large adjustment bolt, reinstall the
spindle housing side cover and reconnect the spindle blow through solenoid connector on the rear
column. This completes the adjustment.
