TORK-LOK ARBORS AND COLLETS
The Tork-Lok arbor design answers the need for a completely versatile workholding device. Precision ground flats on collets and arbors improve long-term accuracy and torque transmission. Standardization of components permits interchangeability and combination possibilities. Locates straight or tapered holes on true center.
INSTALLATION AND OPERATING INSTRUCTIONS
Safety StopsThe expansion safety stop is fixed in all styles and requires no adjustment. The contraction or loading position safety stop is adjusted to suit the part being chucked.
PreloadAll collets are manufactured to include a preload. Collets should not be adjusted below the range minimum for that collet. Preloads are .008 average on sizes from .500-.874 and .015 from .875-4.467.
Special Work Stop ConsiderationCombination Work Stop and Retaining Sleeve: Restrictor Type Work Stops are necessary for parts whose gripping length is shorter than the collet. Since the Tork-Lok collet expands at both ends, a retaining sleeve is needed to prevent the free end of the collet from over expanding; a Restrictor Expander is used to reduce the expansion safety stop, preventing collet breakage (in case arbor is operated without a part in position).
NOTES: • All Tork-Lok arbor applications require a part stop• If Restrictor Type Stop is used, a special Restrictor Expander is required• Contact us at 1-800-228-BUCK for more information DRAWBAR MODEL
Drawbar should be in forward or push position. Adjust forward expander with Allen wrench until part is a slip fit on the collet. Collet flats both ends must mate.
Collet ChangingDrawbar should be in forward positions. Using Allen wrench, remove forward expander. Collet and rubber sleeve can then be removed. Wash parts in clean solvent. Lightly grease expander flats in contact. Install forward expander. Adjust according to instructions outlined above.
AIR-OPERATED MODEL
Air pressure on the cylinder should be at 70 psi. Adjust forward expander with Allen wrench until part is slip fit on the collet. Collet flats on both ends must mate.
Collet ChangingWith air pressure at 70 psi, follow instructions listed in Drawbar Model.
To Interchange AssembliesApply 70 psi, remove mounting screws, turn arbor assembly counterclockwise until drawbar disengages from piston assembly.
To mount assembly, apply 70 psi. Be sure threads on drawbar are clean and oiled. Turn arbor assembly clockwise until face contacts cylinder. Back off to align tapped holes in cylinder. Insert screws and adjust according to instructions outlined above.
