What is the most commonly used workholding device on the surface grinder? The permanent magnet chuck. From a standpoint of leaving the least residual magnetism in a workpiece, which type of magnetic chuck is preferred? The electromagnetic chuck with degaussing circuitry.
Workholding. Walker engineers and manufactures the highest quality electromagnetic, electropermanent, and permanent magnetic chucks for grinding, machining, milling, turning, EDM, and molding applications. We also offer special chuck designs to meet our customers'' unique application needs.
For grinding internal surfaces of simple circular work piece, the chuck may be used as a standard work holding device. It required special jaws can be provided for the chuck. However, for many components special fixtures may have to be made which are designed on same lines, as the lathe fixtures.
Surface grinding is the most common of the grinding operations. It is a finishing process that uses a rotating abrasive wheel to smooth the flat surface of metallic or nonmetallic materials to give them a more refined look by removing the oxide layer and impurities on work piece surfaces.
A workholding device for use with grinding machines having a grinding Wheel and a base with a post in parallel relation to the axis of the wheel, a base bracket, means for adjustably clamping the base bracket on said post for adjustment at its free end toward and from the grinding wheel, a supporting bracket pivotally mounted upon the free end ...
The tolerances that are normally achieved with grinding are ±2 × 10 −4 inches ( μm) for grinding a flat material and ±3 × 10 −4 inches ( μm) for a parallel surface. The surface grinder is composed of an abrasive wheel, a workholding device known as a chuck, either electromagnetic or vacuum, and a reciprocating table.
The work holding devices are used to hold and rotate the workpieces along with the spindle. Different work holding devices are used according to the shape, length, diameter and weight of the workpiece and the location of turning on the work.
Oct 25, 2014· Principle of the Surface grinding machine • Surface grinding is used to produce a smooth finish on flat surface. It is a widely used abrasive machining process in which a spinning wheel covered in rough particles cuts chips of metallic or nonmetallic substance from a work piece, making a face of it flat or smooth.
A workholding device that holds a workpiece to its surface through air pressure. Vacuum chucks can be used for nonmagnetic workpieces during surface grinding. vises: A workholding device with one fixed jaw and one moveable jaw. Vises are often used to hold simple rectangular or cubic workpieces on a surface grinder. vitrified bonds
