Step Chucks & Closers 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...

Step Chucks & Closers 5C Emergency Emergency Step Chucks are made for those situations where time does not allow for the ordering of a precision machined 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...

Step Chucks & Closers Emergency 5C - A2-5, A2-4 Hardinge® Emergency Step Chucks used on A2-5 and A2-4 5C spindles have the same criteria as regular step chucks except the shank is longer. The closers are made of steel. • The A2-4 Closer is used on the Hardinge CONQUEST® GT Lathe • The A2-5 Closer is used on the Hardinge CHNC®-5C and HXL A2-5 5C spindle – the same closer used on all A2-5, 16C Spindles Because these 5C Step Chucks have a longer shank than standard 5C Step Chucks, they can only be used on Hardinge CONQUEST GT, CHNC-5C and HXL A2-5 5C lathes. A2-4 and A2-5 hardened and ground...
