Lathe Chucks
A chuck is a specialized type of used to hold an object, usually an object with , especially a object. It is most commonly used to hold a rotating tool (such as the in a or a rotating workpiece (such as the or blank in the headstock ).
Some chucks can also hold irregularly shaped objects (ones that lack
radial symmetry). In some applications, the tool or workpiece being held
by the chuck remains stationary while another tool or workpiece rotates
(for example, a drill bit in the tailstock spindle of a lathe, or a
round workpiece being milled by a).
Many chucks have jaws, which are that are arranged in a radially symmetrical pattern (like the points of a to hold the tool or workpiece. Often the jaws will be tightened or loosened with the help of a chuck key, which is a wrench-like tool made for the purpose. Many jawed chucks, however, are of the keyless variety, and their tightening and loosening is by hand force alone. Keyless designs offer the convenience of quicker and easier chucking and unchucking at the expense of higher gripping force to hold the tool or workpiece. Collet chucks, rather than having jaws, have which are flexible collars or sleeves that fit closely around the tool or workpiece and grip it when squeezed.A few chuck designs are more complex yet, and they involve specially shaped jaws, higher numbers of jaws, quick-release mechanisms, or other special features.Some chucks, such as magnetic chucks and vacuum chucks, are of a different sort from the radially symmetrical mechanical clamps mentioned above. Instead, they may be surfaces (typically flat) against which workpieces or tools are firmly held by or force.To chuck a tool or workpiece is to hold it with a chuck, in which case it has been chucked. work whose workholding involves a chuck is often called chucking work. that specialize in chucking work are often called chuckers.
