Internal or external threads of different pitches can be produced by. In repulsion motor, zero torque is developed when. In repulsion motor, maximum torque is developed when. A power chuck has jaws operated by pneumatic or hydraulic pressure, automating the securing of a workpiece.

The operator installs the correct jaws and closes the chuck, clamping the workpiece in place. The primary advantage of a power chuck is increased efficiency, along with more consistent pressure on the workpiece.

Explanation: Three jaw chuck is also known as universal or self centering chuck. The majority of the chucks have two sets of jaws for holding internal and external diameters.

All collets have a distinctive length and diameter. Generally collets are used on smaller work pieces than typical three-jaw chucks. Though chucks can also be used for smaller work pieces, collets are much more useful and better grip the items being used. Compared with standard triple-jaw chucks with soft jaws, standard collets tend to be inexpensive and more accurate for gripping in the small-to-medium range. Conversely, three-jaw chucks are usually ineffective and cumbersome when used to grip items this small.

Commonly used to hold endmills, drills, taps and reamers, ER collets exert clamping force when tightened with a nut. Other well-known toolholding alternatives include shrink fit and Weldon flat — also known as side lock — as well as hydraulic and milling chucks.
