Gantry structure with fixed-beam and movable table. The fixed-beam is equipped with vertical ram-type boring and milling head. - details see: https://www.machineto.com/cnc-plano-miller-with-fixed-beam-moving-table-10130827

Features:

* Gantry structure with fixed-beam and movable table. The fixed-beam is equipped with vertical ram-type boring
and milling head. The table moves along bed guideway in longitudinal direction.
* Constant-current hydro-static pressure rectangular guideway for X axis for heavy duty cutting, rolling-sliding compounded
long-span rectangular ladder type guideway for Y axis, 500*500 square ram for Z axis.
* AC-servo motor driving ball screw or double gear & rack transmission for X axis, Ac-servo motor driving ball screw
transmission for Y and Z axis. Three axis position measurement adopts encoder to realize semi-closed loop control.
* AC servo motor is connected to the spindle unit via automatic two speed gear-box, so the spindle can realize low
speed & big torque heavy-duty cutting and high speed & constant power precision cutting. and it supported by high
precision special bearings.
* With automatic lubrication system and chip & coolant liquid collection function.
* ATC and the 4th axis are optional.
