LESTHER J-CNC 650G Gantry Type Double Column 3 Axes Machining Center

Gantry type double column 3 axes machining center perfect for machining extra large work pieces. 24-tools magazine.

Machine Features

  • Fixed table in combination with travelling column and beam that makes the machine suitable for machining extra large work pieces.
  • X-axis travel is transmitted through pinion/rack and driven by a gearbox, featuring high torque output, no backlash and high positioning accuracy (optional).
  • X-axis rapid traverse rate is 36 M/min. Upon request, high rapid traverse rate up to 50 M/min is available (optional).
  • Three axes are equipped with P class high precision linear guide ways. X,Y,Z-axis ball screws are directly coupled with servo motors.
  • 24-tools magazine.
  • Syntec controllers-PC-based, (Opt. Mitsubishi, Fanuc and Siemens).
  • To avoid the tool interference , the design is conducive to machining complex part
  • To the multiple face machining in the once , good for the face position accuracy
  • When the 5 axis machining, tool can fit the irregular face
  • 4 linear guides for Z axis, with high rigidity head
  • Z axis with penumatic balance system , improve Z axis reactivity
