Step Chucks are used for accurately holding work up to 6" in diameter. Castings, moldings, stampings and machined parts are held rigidly and accurately. Tubing can be held without crushing or distorting. Accurate gripping, the same as with collets, is yours when you use regular- and extra-depth capacity step chucks for holding larger diameters.
Regular-Depth Step Chucks are 3⁄8" larger in diameter than the rated size so the full capacity may be readily applied to a depth of 1⁄2". A regular-depth step chuck closer is required for each rated size.
Extra-Depth Step Chucks are made so the full rated capacity may be applied to a depth of 11⁄4". An extra-depth step chuck closer is required for each rated size. Small closing angles are available on step chucks for non-rotating use.
Step Chuck Closers are required when using step chucks on rotating spindles. Step chuck closers fit directly to the machine spindle. An inside taper corresponding to that on the step chuck places the closing pressure over the stepped area of the chuck, resulting in greater gripping power and accuracy. When ordering step chuck closers, specify for taper or threaded nose for 5C models or A2-4, A2-5, A2-6, A2-8 spindle noses. A step chuck closer is required for each rated size step chuck. The closer mounts directly on the spindle nose.
