Model : JW-31, JW-41


  • Ultra-high Stability at High Speed Machining
  • 45° Slant Bed with ridig Construction with Travel 750mm, could add travel every 500mm for Z axis.

Z axis side

  • Bigger Z Axis slideway with double side Taper Gib to keep Z axis accuracy and rigidity, also to keep cutting more stable and tooling longer life.


  • Tailstock Body use double clamping cylinder to fix in Slideway to keep its rigidity. Option accessory for Programable Tailstock with MT 4 Center, Quill Diamenter 110mm with travel 110mm.

CNC operation panel

  • operation panel can be turned 60°, which is good for handel. under has Drawbox to put the tooling . Steanless Panel can resist Oil and dirty , so the life is much longer.
