CNC Double Column Machining Center

Special Designs for SIGMA CNC Double Column Machining Center

    1. Machine Base
      The X-axis linear guideways completed to support the table that maintains the highest precision at any position with zero overlay. SIGMA CNC special design - Two columns distance from 2500mm to 3500mm that is equally supported with Three roller type linear guideways. Two columns distance 4000mm that is equally supported with Four roller type linear guideways. It’s for table’s positioning accuracy, loading balance and prevent heat deformation.
    2. X-axis Ball-screw Supporter It can make the ball-screw life longer, increases position accuracy and position velocity.
      SIGMA CNC special design for columns distance 2500mm and higher models or limited to the X-axis is 3 or 4 guideways machine base.
    3. X-axis Gears Transmission
      Additional X-axis free backlash drive (SIGMA CNC Patent).
    4. Y-axis Ball-screw Supporter
      It can make ball screw life longer, increases position accuracy and position velocity. And, reduce the vibration when machine doing the heavy cutting.
      Machine model columns distance over 2500mm.
    5. Special Design for Beam & Saddle – Three linear guideways on Y-axis (SIGMA CNC Patent)
    6. Special Design for Saddle & Spindle Ram – Four linear guideways on Z-axis (SIGMA CNC Patent)
    7. Heads made by SIGMA CNC
      Extension Head max. 4500rpm (360 / 560mm)
      90゚Angular Head max. 3000rpm
      35゚、45゚Angle Head max. 3000rpm
      Swing Divided Angle Head max. 3000rpm
    8. Splash Guarding Glazed Splash Guard (Standard)
      Glazed Splash Guard with Telescope Door 3-piece (Optional)
      Full Splash Guard (Optional)
    9. SIGMAP Human Interface by SIGMA CNC (For Fanuc controller only)
      Graphical interface is easy to operate for Operators.
