A circular gold jig system gives a single unit the possibility for a large throughput in common feed inlet. This has for outcome a feed system without splitters and a better pattern of cross-flow with less negative side effects.  Jigs are the best all-round units for coarse gold separation in roughing service but good recovery is limited to gold grains larger than – μm in well-classified feed. In the science of mineral processing technique, beneficiation processes (with and without gravity separation) have been extended by investigative research to include compound water cyclones and rotating bowl separators in which centrifugal forces are used to enhance gravity differences, and combined gravity/froth flotation techniques and centrifugal jig separation. Though used largely on milling machines, fixtures are also designed and used to hold. The device holds the workpiece at a 30degree cant. In this post. The jig system definition limit issue in woodworking is a matter about which I have considered at length. Difference Between Jigs and Fixtures. More than any other tool jig system definition limit technique in the woodshop, jigs and fixtures demonstrate the "bottom-up" aspect of woodworking; that is, it is a truth that the majority of woodworking devices created result from woodworkers solving a problem on the the floors of their defniition It could have been seeing that a single-edged chisel would be made more efficient by having a series of edges, and thus the first lijit hand saw was conceived.

The work 1 is clamped by rotating the cam handle 19 which also locates it. The box jigs are generally employed to drill a number of holes on a component from different angles. Fixtures are usually named after the type of machining operation for which they are designed and employed.

It is quite easy-to-hold regular workpieces on lathes in standard job holding devices like chucks and collects, between the centre and on mandrels or faceplates. But irregularly shaped components offer a lot of difficulties in holding them correctly. Simple odd shaped jobs can be held in chuck also, say by proper adjustment of jaws in a four-jaw chuck or by using shaped soft jaws. However, workpieces having complicated shaped have to be necessarily held in position with the help of turning fixtures.

These fixtures are normally mounted on the nose of the machine spindle or on a faceplate and the workpieces held them. These fixtures should be carefully designed, to be rigid enough, with minimum overhang should grip the workpieces very firmly, should not carry any dangerous projections for the machine operator or tool or both and should be able to provide proper support to him to thin and weak sections of the workpieces during the operation.

These fixtures are used on milling for carrying out different milling operations on workpieces. The fixture is properly located on the table of the machine and secured in position by means of bolts and nuts. The table is shifted and set in the proper position, in relation to the cutter. The workpieces are located no the base of the fixture and clamped before starting the operation.

Since the cutting forces involved are quite high, and also intermittent, the clamping elements. Proper locating of the fixture on the machine table is usually achieved with the help of two tenons provided under the fixture base.

These tenons enter a T-slot of the table to provide the required location. The fixture base can then be secured to the table by means of T-bolts and nuts. These fixtures are used on different types of broaching machines to locate, hold, and support the workpieces during the operations, such as keyway broaching operations, such as keyway broaching, hole broaching, etc.

The use of a clamping plate as a fixture for internal pull-type hole broaching. Several different forms of fixtures are used in grinding machines to locate, hold , and support the workpieces during the operations.

These fixtures may be the standard work-holding devices, such as chucks, mandrels, chuck with shaped jaws, magnetic chucks, etc. For example; a vertical surface grinder with a rotary table will normally have a rotary fixture secured to its table.

Similarly, a plain or string fixture may be provided on a surface grinder with the reciprocating table. A drill grinding attachment is a glaring example of a standard fixture used for grinding of drill geometry. Whatever be the types of fixture designed for grinding operation, it should have provisions for supply and exit of coolant, mounting of wheel dressers and should be properly balanced, if it is a rotating fixture.

One of these incorporates the principle of a drilling jig, and in this, the boring bar tool is guided through a pilot bush. Although this fixture incorporates almost all the common principles of jig and fixture design, their construction need not be as sturdy as that of the milling fixtures, because they never have to bear as heavy cutting loads as involved in milling fixtures, because they never have to bear as heavy cutting loads as involved in milling operations.

Several components need machining on the different surface such that their machined surface surfaces or forms are evenly spaced. Such components are required to be indexed equally as many as the number of surfaces to be machined.

Obviously, the holding devices jigs or fixtures used are made to carry a suitable indexing mechanism. A fixture carrying such a device is known as an indexing fixture. Tapping fixture is specially designed to position and firmly secure identical workpieces for cutting internal threads in drilled holes in them.

Odd shaped and unbalanced components will always need the use of such fixtures, especially when the tapping operation is to be carried out repeatedly on a mass scale on such components. It is the name given to the fixture which holds two similar components simultaneously and facilitates simultaneously machining of these components at two separate stations.

While one workpiece is machined at one station. Both the operations according to the requirement may be similar or different. Once machining at both the stations is over, the fixture is indexed through degrees so that the first component is shifted to the second station for the second operation and the finished component to the first station.

The finished component is then uploaded here, replaced by a fresh component and the first operation performed on it. The cycle goes on repeating, which enables mass production of components at a fairly high speed.

Welding fixtures are carefully designed to hold and support the various components to be welded in proper locations and prevent distortions in welded structures. For this, the locating element need to be careful, clamping has to be light but firm, placement of clamping elements has to be clear of the welding area.

The fixture has to be quite stable and rigid to withstand the welding stresses. In many cases, a preferably and commonly used practice is to first tack weld the structure by holding it in welding jig and then transfer it to a holding fixture for full welding. This helps in reducing the chances of distortion considerably and the fixture is subjected to lesser stresses. The function of these fixtures is to hold different components together in their proper relative position at the time of assembling them.

For example, two or more steel plates can be held together in relative positions and riveted. These fixtures, which are used for holding the components for performing mechanical operations, are known as mechanical assembly fixtures.

Against this, there are other types of fixtures which the components are held for joining, such as the welding fixtures are also assembly fixtures, but for hot joining. The following are the advantages of jigs and fixtures in mass production work. So now, we hope that we have clear all your doubts about Jigs and Fixtures.
