UNILOCK rectangular chucks are well suited for mono-chuck applications. They are available in several sizes, and when matched to the footprint of the workpiece, they provide maximum access from the remaining five sides.
The EDM 100/150 has the lowest profile of all UNILOCK chucks, and the new AFM 146 is not far behind. The AFM 105/65 and the ESM 100/75 are the two narrowest chucks in the UNILOCK family and can be placed very close to the edge of a fixture or workpiece. For extremely large and heavy parts, the new ESM 180/150 with a new robust knob series is your answer.
