(1) High Rigidity Large CrossrailCrossrail has a wide cross-section to prevent deformation by saddle movement.(1) High Rigid Double Column without overhangOverhang is eliminated to remove vibration during machining.(2) 3 Rows of Linear GuidesAn additional linear guide is placed in the center section of the table to prevent table deflection when a workpiece is placed on it.(2) X-axis Twin Ball ScrewX-axis drive is highly rigid with twin ball screws to move heavy workpieces and restrain table from yawing.(3) High Rigidity Synmetrical StructureSynmetrical structure is applied to prevent deformation of main machine.(3) Thermally Stabilized ColumnThermally stabilized column is standard, reducing the affect of temperature change.(3) Wide ColumnsWide columns with 4 rows of linear guides placed on the front side and inside on the double columns support force at acceleration and deceleration and cutting reaction force rigidity.
Deformation of ball screws is reduced by cooling the motors, support bearings and ball screw nuts, eliminating any heat generation.
Servomotors are directly connected to both ends of ball screws.
"Zero Gap Drive System" prevents the loss of motion accuracy from backlash and minimizes the wobble in machining path.
Max. step from reference surface: 5μm
The precision spindle and the stable mechanical structure that supports it make it possible to eliminate misalignment of the tool edge position and reduce form errors.
