block diagram of double column jig boring machine

Answer 1

Meaning of Jig Boring:

Jig borers are used for locating accurately and making the numerous holes necessary for jigs, fixtures, gauges and other precision parts. Although the single-point boring bar is the most important tool used in jig borers, yet drills, reamers and counter-borers are also used. The jig boring machine is developed from a locating machine and is relatively a new type of machine. This machine is rugged enough for heavy cuts and sensitive enough for light cuts.
