ATS Systems Ultimate Chuck Installation and Operations Manual
b. (jf the jaw stroke is short) you will need to purchase a set of half-pitch base jaws and when necessary
switch with your normal base jaws to grip close to the start of the jaw stroke.
It is very important that each time you chuck a part you note if you are near the end of the
jaw stroke and risk not properly holding the part. If this happens, adjust all three jaws in one step
and use half-pitch base jaws if necessary.
(This point may be a bit confusing, so spend as much
time as necessary until everyone understands.
- Are there any questions?
Lubrication is important on any chuck. On this high-tech, high performance chuck it is particularly
important. See manual sections 5.2 and 1.3.5.
- Unless the chuck is properly lubricated your grip force might only be 50% of what it would be with
proper lubrication. You could throw parts.
- Use only ATS Systems’ KO5 grease. Grease chuck every 24 hours of operation, two shots of KO5 per
grease fitting with the chuck in the full “open-jaws out” position.
- Fully stroke the chuck (10) times after lubricating to distribute grease to internal components.
- At the start of each shift and after every 50 clamping cycles, actuate the chuck full stroke 5-10 times
without gripping a workpiece to internally redistribute grease throughout the chuck.
- Clean jaw guideways when changing jaws, or at least once per shift if no jaw change is required, and
lightly coat sliding jaw surfaces with KO5.
(Demonstrate sweeping chips out of the guideway located
at the 6:00 position.)
With the cylinder that is on this machine, (decide if comment "a" or "b" below is appropriate.
Usually it's "a". A "b" condition is rare.)
a. and with the maximum hydraulic pressure the machine has available, this chuck is operating at ___ %
of it's maximum rated grip force. Note that the Ultimate Chuck's maximum grip force is probably 1.2-
1.5 times that of a standard chuck and anything above 65% is typical. Also, to get the same static grip
force as the standard chuck you need to increase the pressure 30%. So if you have pressure settings
recorded for jobs you run on this machine, increase them by 30% up to the maximum. If you can't
achieve the static grip force you had before it's probably not a problem. What you need isn't static grip
force when the chuck isn't rotating, but remaining grip force when you are at cutting speed. Do the
calculations for the jaws you are using or use a grip force gauge and limit your speed to a 50% grip
force loss.
b. the maximum hydraulic pressure the machine has available would give too much drawbar pull for this
chuck and the chuck would be damaged. Because of this I've noted on this tag that the pressure should
never be set above ___ PSI. For most any application you shouldn't need more than 90% of that
pressure.
Any questions?
