Contact an Expert for PricingAsk a Representative
Hardinge 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, which permits stepping the chuck to its full capacity without cutting into the pins. Regular-capacity step chucks are 3/8" larger, and extra-depth capacity 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 1-1/4". A regular- and extra-depth step chuck closer are required for each rated size.
