Supertec introduces three sizes of jig grinders covering a full range of capability. Models offered include the pictured JG-510M (20" x 12" x 4" x 13" X,Y,Z,W), the JG-1270CM (47" x 27" x 4" x 16") and the JG-1010G (39" x 39" x 10" x 16"), a double-column style.

The JG-510CM model has an X- and Y-axis positioning accuracy of ±0.000060" and a planetary grinding roundness of 0.00004". The Z-axis is driven by a high-speed linear motor for faster acceleration and greater repeatability.

All models utilize the FANUC 31i-B control for 4-axis simultaneous movement with 12 grinding modes including user friendly automatic pecking macros.

A KSK brand German-made hydrostatic spindle with an rpm up to 60,000 is used for greater accuracy and reliability. Air spindles for speeds up to 150,000 rpm are available based on application.
