Grinding uses fixed abrasives—the abrasive particles are bonded to the paper or platen—for fast stock removal. Polishing uses free abrasives on a cloth; that is, the abrasive particles are suspended in a lubricant and can roll or slide across the cloth and specimen. A book edited by Marinescu et
Sep 19, 2014· 4.0 Grinding Fixture • The standard magnetic tables are used to rest workpiece such that resting surface will be parallel to the surface to be ground. • However, for light workpiece with lesser resting area, the resting area tends to tilt and fly off the magnetic table due to high speed of grinding wheel and due to high feed, also.
Optical geometry and special tooling design. Geometry determines manufacturing processes for making mold. If simple, turning, lapping, grinding and polishing. Asphere needs different set of operations. Freeform needs diamond turning, hand polishing. Designs for special tool must be done during mold design. Finishing. Abrasive lapping and polishing

1. Center type grinding with axis feed: (Work spins slower) similar to cutting thread in the lathe. difference a shaped grinding wheel is used instead of the point cutting tool. (even multiple shaped grinding wheel can be used ). Speed –given by the RPM of the grinding. Several passes are necessary to complete the thread. 2.
The fixture arrangement is very simple and leads to a smooth grinding operation and also to increase the repeatable usage of such drill bits. This fixture is fixed to the bench grinder by means of some clamping arrangements. Various types of drill bits can also be grinded by using this fixture by with respect their respective tool geometry.
Main Parts Of Jig and Fixture -Jig and Fixture Design. 5. Define sandwich jig. These jigs are a form of plate jig with a back plate. This type of jig is ideal for thin or soft parts that could bend or wrap in another style of jig. Here again, the use of buildings is determined by the number of parts to be made. 6.
