The Today, Tonight, Tomorrow high-precision workholding system enables converting the basic chuck for OD, ID and 3-jaw clamping operations in a matter of seconds. The SPANNTOP chuck is designed for improved OD workholding with a rugged, balanced design. ID capability with the MANDO Adapt is enhanced by clamping sleeves to provide optimal holding pressure while cushioning the workpiece to avoid damage. The jaw module can be used for both conventional and larger-sized parts, and accuracy is promoted through 80 percent engagement of the part diameter. The versatile chucks are suitable for use by conventional machine shops, specialty gear manufacturers, medical appliance producers and others, and are suitable for automated operations.
