Makino's D500 5-axis Machining Center

Makino utilizes three direct drive motors forthe D500's C-axis rotary table and the A-axis trunnion. One direct drive motorcontrols the C-axis motion. Two direct drive motors control motion in theA-axis - one at each end of the trunnion. The dual motor design providesgreater torque and rigidity. Twist and torsion in the trunnion is eliminated toachieve accuracy.

The D500 axisconfiguration provides added performance. The length of the trunnion assemblyruns parallel to the X-axis motion only, making trunnion assemblydeflection-free during quick axis motion for greater accuracy than traditionalfive-axis configurations.

The machinefeatures roller linear guides across all linear axes for extra rigidity. Y andZ axes are located above the work zone, the X axis is located in the bed sideof the machine. Accuracy is achieved with independent axes, in which movementremains uninfluenced by the characteristics of combined axes.

The work zone for the D500 is 500 x450 mm. The X-, Y-, and Z-axes provide strokes up to 550, 1,000 and 500 mm,respectively. Rotary table axes A and C provide rotational motion of +30 to-120 degrees on the A-axis and a full 360 degrees on the C-axis. The D500 iscapable of feedrates of 50m per minute.

Thearchitecture of the D500 is a "closed-loop" design that increases overallstiffness and rigidity of the machine structure. This means all force impactedpoints of the machine are in close proximity to its support structure.

Thisfive-axis machine includes Makino'sThermal Stabilizer system that includes core cooled ball screws and heatinsulation systems. This system allows for sustainable dynamic accuracy inunstable shop environments. Twin internal chip conveyors remove chips from thework zone efficiently where they are evacuated from the machine by a lift-upchip conveyor

The machinecan be easily upgraded for automation. An Automatic Pallet Changer can be addedto the machine at any time. Additionally, a stand alone machine can beup-graded and integrated to a full scale pallet system that can include Makino a51 horizontal machining centers.

Inaddition to the D500, Makino offers 5-axis machining centers based on both a verticalmachining center and horizontal machining platform, including specialty 5-axismachining centers designed to machine largeaerospace structural components.
