What do you do when you need a new chuck?

Buy a HarcÊnge® Sure-Cri ff 3-sJaw Power Qjick-Change Jaw Chuck.

The Hardinge® Sure-Grip series of 3-j aw power chucks are lever-operated, counter-cmtrifugal and dynamically balanced. This enables you to continually operate your CNC lathe at higher spindle speeds and feed rates with less concern for loss of jaw force normally associated with other manufacturer's chucks. Hardinge chucks are directly mounted to ANSI A2-4, A2-5, A2-6 and A2-8 spindles, eliminating the need to adjust the chuck to the centerline of the spindle. Chucks are offered in 4", 5", 6", 8", 10" and 12" sizes with the largest thru-holes in the industry reducing bar stock restrictions.

AH Hardinge chucks are designed using the latest in design software FE A Analysis is done during the design process to accurately depict structural deflections, stress levels, thermal response and vibration response of the assembled components.

The Hardinge Quick-Change Sure-Grip power chucks have the same features as the standard Sure-Grip chucks plus the ability to quickly change the j aws during setup. Each top j aw changes with the simple turn of a single locking bolt in less than one minute (much faster than conventional jaws). No special tools are required, just a standard hex wrench
