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.

Dec 21, 2009 A chuck is a work holding device. It is used for holding work over a lathe machine, which is having large length and small diameter, and also for jobs, which are unable to mount on between the centers i.e., head stock and tail stock centers. A chuck is also employed when a non-axis symmetrical object is to be mounted over the lathe.
The magnetic clamping or magnetic workholding can be used in a wide range of metal processing. Suitable for the daily use in grinding, milling, EDM and measuring. The magnetic technology enables high precision, distortion-free clamping and longevity.
