There are also independent-jaw (non-self-centering) chucks with three jaws, but they offer few advantages and are very rare. … Collets are most commonly found on milling machines, lathes, wood routers, precision grinders, and certain handheld power tools such as die grinders and rotary tools. Commonly used for holding silicon wafers during lithography processes, an electrostatic chuck comprises a metal base-plate and a thin dielectric layer; the metal base-plate is maintained at a high-voltage relative to the wafer, and so an electrostatic force clamps the wafer to it. However, it is a misconception that such chucks necessarily offer more precision in holding solid workpieces than conventional three-jawed self-centering chucks. Selection of the standard to be used is an agreement between the supplier and the user and has some significance in the design of the chuck.
