The most basic workholding device is a simple clamp, but workholding can also involve complex fixtures that are custom-built for particular parts. Other common workholding devices include vises and chucks, as well as indexers or rotary tables that are able to change the part's position while it is held, so the machine can reach various features.
Vacuum workholding is a highly effective technique for holding thin, irregular shaped or non magnetic parts. Although parts with a large surface area are ideal, as the holding force is also large, there are also techniques for holding small parts. Vacuum workholding can be applied in milling, turning, grinding and drilling applications.

Magnetic Workholding Chucks - Driving competitive edge into precision machining operations . Efficient milling, grinding or cutting requires good machine selection, quality cutting tools, clean fluids and, equally as importantly, an efficient means of clamping or holding the workpiece. With ever faster processes and cutting speeds, it's a vital ...
Workholding is the generic term for any device used to firmly hold your workpiece while machining it. Closely related terms are "jigs" and "fixtures." A fixture holds your workpiece while it is being cut. A jig holds the workpiece and also guides the cutter.
Drill chuck is a tool holding devices used to hold drill bits tool or drill in a drilling machine. Lathe Centers The Center is a work holding devices in lathe that is used to support a long jobs in between headstock and tailstock to carry out a lathe operation.
3:Grinding Fixtures: The work holding devices for grinding operations will depend upon the type of the grinding operation and the machine used. A mandrel is the most common fixture used for grinding external surface of the work piece, a mandrel is hardened and is held between centers of a machine. The mandrel is used for internal chucking or ...
Magnetic Workholding since 1896 Magnetic workholding chucks have been a cornerstone of Walker Magnetics ever since Oakley S. Walker invented the first magnetic workholding chuck back in 1896. The benefits are obvious: Magnetic chucks offer a reliable solution for fabricators who want to grind or mill steel workpieces without damage that can come from mechanical […]
Workholding Devices Vises are generally used with milling machines while chucks or collets are used when running a lathe machine. Sometimes, a part may need a customized workholding setup in order to secure the piece properly during machining. Fixtures and jigs are examples of customized workholding devices.
