Overview

  • 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 jig grinder is very similar to a jig borer, in that the table positioning and spindles are very accurate (far more than a manual milling machine or lathe).
  • It is almost used by tool and die makers in the creation of jigs or mating holes.
  • There are usually many peripheral elements to a jig grinder, including linear motors, pneumatic grinding head (or electrical grinding head), and various cooling systems for supplying coolant to the work and machine itself.
  • The machine operates by a high speed spindle rotation.
  • The spindles are removable and interchangeable to achieve varying process speeds.
  • Some spindles are fixed speed (60,000 rpm), others are adjustable (30,000 ~ 50,000 rpm), and still others are very high speed (150,000 rpm).
  • The main spindle has a wide range of speeds to ensure proper grinder feed rates are maintained.
  • The machines have a standard X and Y table.
  • All axes are indexed to 0.0001 on the handwheels.
  • The machine head adopts linear motors.
  • The spindle rotates at a variable speed and with an accuracy of 0.0001 for very precise holes and grinding.
  • A reliable jig grinder will let work to achieve a higher degree of efficiency level.
  • These features are all critical in precise process.
