Sure-Grip 3-jaw Power Chucks

Lever-Operated and Fully Balanced
Hardinge Sure-Grip Power Chucks are lever-operated, counter-centrifugal 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 wedge-style chucks.

Direct Mount
4", 5", 6", 8", 10" and 12" Sure-Grip Power Chucks mount directly to ANSI A2-4, A2-5, A2-6 and A2-8 spindles, eliminating the added tolerance buildup when using special adapter plates. Sure-Grip Power Chucks come standard with 1.5mm x 60° serrated master jaws designed to ISO specifications. Spindle adapters are required when mounting a large chuck to a small spindle, or when mounting a small chuck to a large spindle.

FEA Design Analysis
Finite Element Analysis (FEA) techniques are used to design and build Sure-Grip Chucks to ensure optimum rigidity and fatigue life. Unique design software accurately depicts the structural deflections, stress levels, thermal response and vibration response of the assembled components. Extreme case loadings are modeled in FEA to determine the effects. This technique fine tunes the engineered design and aids in defining operating specifications while verifying the chuck life expectancy.

Quick-Change Sure-Grip Chucks
Maintain accuracy while increasing productivity with the Hardinge quick-change chuck. The revolutionary patented top jaw design provides top jaw change with the simple turn of a single locking bolt in less than one minute - much faster than conventional jaws! The Hardinge-designed safety feature utilizes centrifugal force and a unique locking system, eliminating the possibility of the quick-change jaws coming off during operation. 6", 8", 10" and 12" chucks accept standard jaws.
