High-Rigidity Mechanical Structure The bilateral gate structure in SIRIUS-1250 is the ideal design for distributing the vibration, the weight, and the heat throughout the entire frame. The machine is built through the finite element analysis to minimize the frame distortion which may be caused by machining condition or environment. The box way design for all axes is perfect for vibration absorption during heavy duty machining, and the Hwacheon-developed air levitation system on the X and Y axes keeps the workpiece stable while cutting a heavy-load subject. The distance between the spindle and the body is designed short, so the machine stays stable after a prolonged operation.

The jet of oil is injected directly onto the spindle bearing for effective cooling, and the motor and the spindle assembly are jacket-cooled to limit the displacement caused by heat. To achieve greater precision, the spindle constantly monitors for possible thermal displacement and makes necessary adjustment in real time.

The servo motor is coupled directly to the drive; and the ball screws are tensile preloaded, so that the heat generated from the ball screws do not cause the distortion and affect the machining precision.
