Precision Jig Grinder




  • JG-1012CM double column Jig Grinder with superstructure fabricated by granite, which is well-known by its excellent damping, low heat conductivity, rust-proof, and corrosion resistance, is capable of stabilizing the machine accuracy and enhancing the roughness on workpiece.
  • Stiffness and accuracy is also enhanced with the motors on three axis (X, Y, Z) direct-driven design transmission.
  • C1 grade ballscrew was adopted, pre-tension by 3°C in temperature increment, which is effectively upgrading stiffness and preventing from deformation during operation.
  • FANUC controller: 31i-B
    X, Y, Z W travel: 1000 x 1000 x 250 x 400 mm
    Plate Flatness ≦ 0.01mm
  • NSK P4 heavy load ultra precise linear guideway with rail width of 45mm is adopted in 3 axis (X, Y, Z) and has a wider engagement in order to a low deformation, high strength, vibration resistance as well as capability of max feed speed of 24 m/min.
  • Feeding movement of Z axis is driven by linear motor, which features instrument with hyperresponsiveness, rigidity, high speed, excellent acceleration, and no backlash and not only simplifies the superstructure but also fulfills rapid and precise machining process.
  • Besides, the two additional German-made vibration insulation pads are also incorporated onside to assure the accuracy and quality.
  • Position accuracy: ± 0.0025 mm
    Repeatability: ± 0.001mm
