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.
