Abstract
This invention relates to chucks. Increasing effective operational rotational speeds of chucks, while reducing loss of gripping power due to such speeds, is achieved by a chuck with a wedge unit (13) having a greater expansion rate than that for a master plate unit (14). A master jaw (63) is balanced upon a master bearing (57) carried by the master plate unit and rocks thereon upon actuation of the wedge unit.
