Use of Collets, Chucks, and Face Plates<br />
SHCS<br />
LC5C-B<br />
HA5C<br />
Face Plate<br />
HA5C – The unit accepts standard 5C<br />
collets and step collets. When inserting the<br />
collets, align the keyway on the collet with<br />
the pin inside the spindle. Push the collet in<br />
and turn the collet drawbar clockwise until<br />
proper collet tightness is attained.<br />
Chuck Chucks and face plates use the 2 3/16-10<br />
threaded nose on the spindle. Chucks that<br />
70 FT Lbs. are have no more than a 5" diameter and<br />
weigh less than 20 pounds are recommended.<br />
Pay special attention when installing<br />
chucks, always make sure that the thread and the outside diameter of the spindle<br />
are free of dirt and chips. Apply a thin coating of oil to the spindle, and screw the<br />
chuck on gently until it seats against the rear of the spindle. Tighten the chuck to<br />
approximately 70 ft.-lb with a strap wrench. Always use a firm, steady pressure to<br />
remove or install chucks or face plates, otherwise damage to the indexing head<br />
may result.<br />

WARNING !<br />
Never use a hammer or pry bar to tighten the<br />
chuck, this will damage the precision bearings<br />
inside your unit.<br />

The A6AC collet closer bolts to the<br />
back of the HRT A6 (See the following<br />
illustration). The drawbar and<br />
collet adapters are designed to mate<br />
with the <strong>Haas</strong> A6/5C spindle nose.<br />
The optional A6/3J and A6/16C can<br />
be obtained from a local tooling<br />
distributor. Failure to follow the<br />
A6AC installation instructions may<br />
result in thrust bearing failure.<br />
NOTE: A special drawtube adapter is required for the 16C and 3J. Make<br />
sure to supply the tooling distributor with spindle/drawbar details as<br />
shown.<br />
