    • Technical Parameters

      ●   This series of models adopt a typical horizontal table type structure, with the headstock side mounted, the boring shaft embedded in the milling shaft hole, the worktable placed on the top of the slide and rotatable, and the vertical movement of the column;


      ●   The main shaft is equipped with a gearbox structure design, which is suitable for both high-speed die cutting and general low-speed high-torque machining;


      ●   Complete a variety of processes in one clamping, suitable for big part milling, boring, drilling, reaming, tapping, turning, turning, etc.;


      ●   Widely used in civil aviation, shipbuilding, railway, mining and metallurgy, engineering machinery, valves, new energy and other industries.

      01、strong structure

      Large size component castings, optimized reinforcement, strong.


      02、extended machine bed

      Static pressure guide rail and extended machine bed enable longer travel, low friction, creepless and stable operation.



      03、column wall design

      Reinforced column wall thickness, deformation resistant.


      04、transmission system

      Two grade speed change yields high torque reaching 9000Nm.
