Obsolete Chuck Crossover

Chuck Selection

ATSC AT/BVC4-JAW

INDEPENDENT

APPLICATIONS:

• Precision machining• Large quantity productions•Higher RPM needs

APPLICATIONS:

• Tool room applications•Grinding

APPLICATIONS:

• Tool room applications•Grinding•Odd-shaped parts

How do you determine what type of chuck and mounting plate is required for the application?

What size of chuck?• For scroll chucks, do not exceed the swing diameter over the

cross slide• For independent chucks, the next larger size may work

What accuracy and repeatability is required?•High precision – the ATSC chucks provide .0005 TIR on

duplicate parts•General I.D. or O.D. work – the BVC chucks provide .001 TIR on

duplicate parts

How many jaws are required?• 2-Jaw – special applications• 3-Jaw – conventional machining• 4-Jaw – square and offset work• 6-Jaw – 2nd operation or thin wall parts

What type of jaw is needed?• The most common are the top reversible jaws. These can be

used for both I.D. or O.D. work and production work•2-piece jaw chucks can be adapted to soft jaws or special

top tooling• Solid jaws are typically used for tool room applications

What mounting is needed?•Determine spindle type using the spindle identifier on page 7•Measure the major diameter of the taper and match to the chart

for the spindle type (page 7)• For threaded spindles, you will need to measure threads per inch

Precision Mated Flats on BothExpander and Arbor Body

Precision Mated Flats on Collet

Safety StopsContractionExpansion

Tork-Lok Arbors and Collets

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.
