Sure-Grip® 3-Jaw Power Chucks 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. Spindle Adapters Spindle Adapters are required when...
