TTSL Spring Loaded Spindle Adaptor
1. Absorbs excess spindle travel while
maintaining axial pressure between spindle and drive tool.
2. Allows axial float
without sacrificing concentricity.
3. Adapts easily to all types of spindles.
Note:
1. At no time during the drive cycle should the TTSL spring be completely compressed.
2. The TTSL spring should not be used to continue the advancement of the stud drivers after the spindle
drive mechanism has been halted.

Automatic Stud Driving
In all stud driving applications it is necessary to coordinate the axial
advancement of the spindle with the RPM and the thread pitch of the stud.
If the advancement is too rapid, excessive pressure will accelerate the wear
on the stud driver. If the advancement is too slow, the jaws will open
and close repeatedly causing damage to the stud and decreasing the accuracy
of the projection height.
When a stud driver is used manually the operator will
quickly learn to apply the necessary pressure to get the stud driver to
operate properly. But when the stud drivers are used on automatic or
multiple spindle applications it becomes necessary to add a TTSL between the
stud drivers and the spindle to obtain the same result.
When the TTSL is installed you simply allow the spindle
to advance 10% faster than the stud is capable of screwing into the
workpiece. The extra 10% will be absorbed by the TTSL and the spring
pressure of the TTSL will assure that the stud driver remains loaded onto
the stud. This greatly reduces the time needed to successfully setup
and fine tune the machinery, and it significantly reduces the risk of tool
failure or breakage.
