Three Sizes of Jig Grinders

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.
