Mother of machine tool parts

  When it comes to highly accurate machining technology, jig boring is better. So say proponents of the century-old machining technique.In the early part of the last century, jig boring started as a better way to make holes. But the technology has since evolved into a more-versatile machining option.

  Manufacturers of mold bases use jig boring and jig milling machines to finish bores with tolerances tighter than 5µm in roundness, perpendicularity and straightness. 

  To achieve the required level of precision, jig borers are designed and built in ways that set them apart from typical machines. For example, jig borers feature components made with tighter-than-normal tolerances, as well as improved rigidity, thermal stability and vibration-damping capabilities, according to Dolan.

 What’s more, jig borers are made to maintain their accuracy for long periods of time. Dolan said it’s not unusual for a jig borer to remain exceptionally accurate for 20 years or more.
