Jig boring machine is similar to milling machine. But the work produced by jig boring is quite precise. If spindle is rigid and machine itself is massive, therefore the defects, deflection, vibration etc. developed due to change in temperature is insignificant. More precise and high quality holes are required in drill jigs, fixtures and dies.
