The Shaper Machine tool used for shaping operation is called shaper. Designed for machining flat surfaces on small sized jobs.If the size of the job is large, then planing isused. In a shaper, the work piece is held stationary during cutting, while the tool reciprocates horizontally. the feed and depth of cut are normally provided by moving the work.
SURFACE GRINDING MACHINE The surface grinding machine is used for grinding flat surfaces. The workpiece is supported on a rectangular table which moves back and forth and reciprocates beneath the grinding wheel. Reciprocating surface grinding machines generally have horizontal wheel spindles and mount straight or cylinder-type grinding abrasive ...
collets of varying shapes and diameters. Work may also be held between the head and tail stock of the lathe or "between centers." Grinding Fixtures – Grinding fixtures are a family of fixtures rather than a single classification. The two major types of grinding fixtures are those used for surface grinding and cylindrical grinding.
The work holding device in surface grinding is known as : A. Chuck: B. Mandrel: C. Tool post: D. None of the above: Answer» a. Chuck: Report. ... » We provide you study material i.e. PDF's for offline use. » We take free online Practice/Mock test for exam preparation.
Work holding devices such as jigs and fixtures are used for holding the workpiece. Jig is workpiece holding and locating device that positions and guides or controls a cutting tool. Drill jig makes it possible to drill, ream and tap hole at faster speed and with great accuracy as compared to that of conventional hand methods.
(d) Work holding devices must be fool-proofing to avoid incorrect loading of the job. (e) Work holding devices must be sufficient rigidity to fully withstand the cutting forces. (f) Work holding devices must be safe in use and loading and unloading. (g) Work holding devices must have a sufficient of clamping force for use of full roughing cuts.
broaching machine and surface grinding machine the job remains fixed on the bed or work table of those machine tools. Fixtures are mostly used in the aforesaid machine tools and jig specially for drilling, reaming etc. for batch production.

5.6 Work holding devices For effective machining operations, the workpieces need to be properly and securely held on the machine table. The following are the usual methods of holding work on the table : 1. Vises : i. Plain vise ii. Swivel Vise iii. Universal Vise 2. V- Block 3. Clamps, T bolts 4. Angle Plate
Holding metal parts with magnets is migrating from surface grinding to broader application in general metalworking processes, especially milling. Advances in magnetic technology are causing many shops to re-evaluate how they hang on to workpieces. Here's a look at how magnets may be a viable workholding solution for your shop.

Work-holding devices for milling – simple work-holding device, e.g. machine vice; more complex work-holding devices, e.g. clamping direct to machine table, angle plate, vee block and clamps, indexing head/device, rotary table Teacher demonstration . in a workshop environment. of specific milling techniques using straightforward workpieces.
WORK HOLDING ON THE SURFACE GRINDER. Chuck setup for a workpiece with a projection on chucking side. The work is supported on laminated magnetic parallels. A set of magnetic parallels & vee blocks can be useful. In these cases, the work must be supported with magnetic parallelsor vee-blocks, specially designedfor grinder work.
This type of work holding devices are employed for holding previously drilled or bored hole so as to facilitate effective outer surface machining. The work is loaded over the mandrels between the centers. The ends of the mandrels are made slightly smaller than the original diameter. This is done for effective gripping of the mandrel in the ...
