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.

- grinding
grinding
Machining operation in which material is removed from the workpiece by a powered abrasive wheel, stone, belt, paste, sheet, compound, slurry, etc. Takes various forms: surface grinding (creates flat and/or squared surfaces); cylindrical grinding (for external cylindrical and tapered shapes, fillets, undercuts, etc.); centerless grinding; chamfering; thread and form grinding; tool and cutter grinding; offhand grinding; lapping and polishing (grinding with extremely fine grits to create ultrasmooth surfaces); honing; and disc grinding.
- jig
jig
Tooling usually considered to be a stationary apparatus. A jig assists in the assembly or manufacture of a part or device. It holds the workpiece while guiding the cutting tool with a bushing. A jig used in subassembly or final assembly might provide assembly aids such as alignments and adjustments. See fixture.
- linear motor
linear motor
Functionally the same as a rotary motor in a machine tool, a linear motor can be thought of as a standard permanent-magnet, rotary-style motor slit axially to the center and then peeled back and laid flat. The major advantage of using a linear motor to drive the axis motion is that it eliminates the inefficiency and mechanical variance caused by the ballscrew assembly system used in most CNC machines.
