Devices Used To Hold Work on Drill Table Points : Devices Used To Hold Work on Drill Table, Enlist the different work holding devices used to hold work on drill table

1. Double finger clamp

Bench Vise

Bench Vise Points : Bench Vise, Definition Definition Metal is often seized in a Machinist’s or Bench Vise while skill is required. The vise is generally mounted for sufficient out on the bench edge to permit extended work to be clamped in. a vertical position.

Difference between Jigs and Fixture

Difference between Jigs and Fixture

Difference between Jigs and Fixture Jigs Fixture 1. Jigs direct the cutting tool. Fixture doesn’t direct the Cutting tool.

Jigs and Fixture

Jigs and Fixture Points : Jigs and Fixture Jigs Jig may be define as a device which holds and positions the work, locates or guides the cutting tools relative to the work piece and usually is not fixed to the machine table. It is usually lighter in the construction.

Parallel Clamp

Parallel Clamp
Points : Parallel Clamp, Definition Definition A parallel clamp, also called tool-maker’s clamp or machinist clamp may be used be clamp work in place.

C-Clamp

C-Clamp
Points : C-Clamp, Definition Definition A C-clamp, shaped like the letter C, is measured by the greatest distance it can be opened between the jaw and the end of the screw. It is made in many sizes and is useful when clamping work to the table of a machine.

Jack screw Clamp

Jack screw Clamp
Points : Jack screw Clamp, Definition Definition The jackscrew, also known as planer jack ranges in height fron1 two inches upward. It may be used for leveling or supporting odd-shaped work.

V-Blocks Clamp

V-Blocks Clamp
Points : V-Blocks Clamp, Definition Definition V-blocks are used in certain milling operations to hold round work. They should be made or purchased in pairs so that one can be placed under each end of bug work. They are made with or without clamps.

Stops Clamp

Stops Clamp
Points : Stops Clamp, Definition Definition In making setups on the milling machine, stops are often required. They assure the operator that the work-piece will not shift out of place under the strain which the cutter put on the work.

An Angle Plate Clamp

An Angle Plate Clamp
Points : An Angle Plate Clamp, Definition Definition An angle plate is an L-shaped piece of cast iron or steel accurately machined to an angle of 900. For milling certain shapes of work, the work piece can he mounted on the angle plate as a work-holding device; the angle plate is then bolted to the machine table.

Step Blocks Clamp

Step Blocks Clamp
Points : Step Blocks Clamp, Definition Definition The step block, supports the strap clamp opposite the work. The step the adjustment necessary to keep the strap level.

Strap Clamp

Strap Clamp
Points : Strap Clamps, Definition Definition Strap clamps, make the ‘clamping operation easier if a good assortment is available. The elongated slot permits some adjustment without removing the nut. Use a strip of copper to protect a machined surface that must be clamped.

Hold-Downs Clamp

Hold-Downs Clamp
Points : Hold-Downs Clamp, Definition Definition Sometimes parallels, or combinations of parallels, of the size required to raise the work above the jaws of the vise are not available. This is particularly true when machining this stock.

Parallel Bars/Strips clamp

Parallel Bars/Strips clamp
Points : Parallel Bars/Strips clamp, Definition Definition Parallel bars/strips are hardened, accurately ground steel bars of various thicknesses, widths, and lengths, which are used to raise the work piece and seat it square and parallel with the base of a vise as.

T-Bolts Clamp

T-Bolts Clamp Points : T-Bolts, Definition Definition T-bolts, fit in the slot of the milling machine table and fasten the work or clamping devices to the machine. A washer should always be used between the nut and holding device. For convenience, having at hand an assortment of different length T-bolt is desirable.

Hold-down Devices

Hold-down Devices Points : Hold-down Devices, Clamping Work to the Table , T-Bolts, Parallel Bars/Strips, Hold-Downs, Strap Clamps, Step Blocks, An Angle Plate, Stops, V-Blocks, Jack screw, C-Clamp, Parallel Clamp Before accurate work can be produced, it is necessary to set up the work correctly. This requires the use of certain attachments and accessories such as milling vises, T bolts, strap clamps, parallels, blocks and jacks, stops, V-blocks, angle plates, washers, nuts, etc. Work must be securely fastened and well supported so it will not move during the milling operation.

Types of Vises

Types of Vises Points : Types of Vises, Plain vise, The flanged vise, Swivel vise, Cam action vise, Toolmaker’s universal vise The shape and size of work to be milled will determine what type of vise must be used. The following types of vises are commonly used.
1. Plain vise
2. The flanged vise
3. Swivel vise
4. Cam action vise
5. Toolmaker’s universal vise

Vises and their Use

Vises and their Use
Points : Vises and their Use, Definition Definition To make the various setups for performing milling machine operations, numerous work-holding devices are used. Their use greatly extends the range of work that can be efficiently done on milling machines. The work must be securely fastened milling operations.
