What is an indexing jig?
Indexing jig is used to drill holes which are spaced equally along a circle. In this example four equally spaced holes are to be drilled on the periphery of the workpiece. The workpiece has a machined bore. The workpiece is located by a C-washer and a nut. A drill bush is fitted in the bush plate.
What are the different types of jig bushes used?
Fixed Bush, Liner Bush, Renewable Bush, Slip Bush, Screw or Clamping Bush.
Which jig used for thin and soft jobs?
Sandwich Jig: This type of jig is used for drilling thin or soft parts to avoid bending, warping etc.
What type of jigs is the simplest of all types?
The template jig is the simplest of all the types. A plate 2 having holes at the desired positions serves as a which is fixed on component 1 to be drilled.
Why should a drill jig stand on four legs rather than three?
4) Jig plate rest pads or legs: A drill jig should stand on four legs instead of flat surface. If the jig stands on flat surface, chips will get under flat surface and imbalance the jig. To avoid imbalance, jigs stand on four legs.
What is automatic drill jig?
Abstract –An automatic indexing drill jig has been designed and fabricated and installed in a drilling machine. It is a supporting device which holds the work, guides the tool and also locating work piece in its position during machining/drilling process.
Which Bush is mostly used in jigs?
Slip-renewal bushes are used for performing more than one operation in same location, like drilling and reaming. These bushings are used with a liner bushing and are held in place by the radial lock and the bushing head.
Why are bushes used in jigs?
A drill bushing, also known as a jig bushing, is a tool used in metalworking jigs to guide cutting tools, most commonly drill bits. Other tools that are commonly used in a drill bushing include counterbores, countersinks, and reamers. They are designed to guide, position, and support the cutting tool.
What are the two categories of jigs?
Jigs are often divided into two broad categories-open and closed. Open jigs are used when machining a single surface of a workpiece, whereas closed jigs are used when machining multiple surfaces.
What is a mechanical jig?
It is a work holding device that holds, supports and locates the workpiece and guides the cutting tool for a specific operation. Jigs are usually fitted with hardened steel bushings for guiding or other cutting tools. a jig is a type of tool used to control the location and/or motion of another tool.
How thick should the jig plate be to support the bushing?
As a general rule, bushings should be only long enough to guide and support the cutting tool properly. As shown in Figure 10-51, the thickness of the jig plate should generally be one to two times the tool diameter.
