What is a boring jig?
Jig boring is used to accurately enlarge existing holes and make their diameters highly accurate.
Jig boring is used for holes that need to have diameter and total runout controlled to a high degree.
Dedicated jig boring machines are designed to machine holes with the tightest tolerances possible with a machine tool..
How boring is done?
Boring processes are typically performed using a lathe, milling machine or a horizontal boring mill. Each machine uses a different mechanism, but they are all designed to enlarge an existing hole in a workpiece — and that’s the defining characteristic of boring.
What does a jig borer do?
The jig borer is a type of machine tool invented at the end of World War I to make possible the location of hole centers quickly and precisely. Often a jig is hardened; for a jig borer this requires the material to be bored first and then hardened, which may introduce distortion. …
What are the applications of boring machines?
Boring machine, device for producing smooth and accurate holes in a workpiece by enlarging existing holes with a bore, which may bear a single cutting tip of steel, cemented carbide, or diamond or may be a small grinding wheel.
What is Jig Grinding process?
A jig grinder is a machine tool used for grinding complex shapes and holes where the highest degrees of accuracy and finish are required. … The machine operates by a high speed air spindle rotating a grinding bit. The air spindles are removable and interchangeable to achieve varying surface speeds.
How many types of boring are there?
4 Types of Boring Techniques Used During Construction. Boring involves the drilling of holes into the ground for many different purposes. In the construction industry, boring is a technique used to explore the underground surface and to determine if it is capable of holding up a building.
What’s the meaning of boring?
boring Add to list Share. As an adjective boring describes something (or someone) that is tedious, dull, and lacking in interest. As a noun, boring refers to the act of drilling a hole, or the hole itself.
What are the different types of boring machines?
There are several kinds of boring processes including horizontal boring, line boring, and vertical boring. Horizontal boring machines bore holes with a spindle that is parallel to the work table. Line-boring machines have a boring bar that is supported on both ends.
What is meant by jig?

Which jig is used for location in bore?
Post jigsPost jigs are used for location from a bore.
What is jig machine?
Jig concentrators are devices used mainly in the mining industry for mineral processing, to separate particles within the ore body, based on their specific gravity (relative density). The particles would usually be of a similar size, often crushed and screened prior to being fed over the jig bed.

How do boring machines work?
With its rotating cutting wheel, the tunneling machine breaks the material from the tunnel phase. … The material is then transferred to the belt conveyer system in the rear of the shield via a screw conveyer while the hydraulic cylinders press the machine forward continuously.
What is the principle of boring?
In machining, boring is the process of enlarging a hole that has already been drilled (or cast) by means of a single-point cutting tool (or of a boring head containing several such tools), such as in boring a gun barrel or an engine cylinder. … Lineboring (line boring, line-boring) implies the former.
