Emergency Step Chucks are made for those situations where time does not allow for the ordering of a hardened step chuck. Emergency step chucks are supplied with pin holes and pins in place for precision machining. Pins are located beyond the maximum rated capacity of the step chuck—this permits stepping the chuck to its full capacity without cutting into the pins. Pins can be used, removed and saved for additional stepping operations.
Regular-Depth Step Chucks are 3⁄8" larger, while Extra-Depth Step Chucks are 3⁄4" larger in diameter than the rated size so the full capacity bore may be easily machined. A regular-depth step chuck can be bored to a maximum depth of 1⁄2", the extra-depth step chuck to a maximum depth of 11⁄4" with 13⁄4" step for the 25C step chuck. A regular- or extra-depth step chuck closer is required for each rated size.
Hardinge Emergency Step Chucks are not designed to be heat treated by the customer. Step chucks with small closing angles are available for use with stationary (non-rotating) workholding devices only. All 5C taper and threaded-nose closers are made from cast iron. All other closers are made of steel.
