Document Type and Number:
WIPO Patent Application WO/2012/099323
Kind Code:
A2
Abstract:
The present invention relates to a highly rigid complex machine having a structure in which parts constituting a shaft are disposed adjacent to the central portion of a column to reduce rolling and pitching, and a stage is disposed on a saddle to improve rigidity. The highly rigid complex machine includes: a bed (400) on the top surface of which Z-axis guide ways (Z1, Z2) are formed in a lengthwise direction; a saddle (300) on which Y-axis guide ways (Y1, Y2) are formed in the front and rear directions perpendicular to the lengthwise direction, the bottom surface of the saddle (300) having a shape corresponding to that of the top surface of the bed (400) so as to be conveyed in the lengthwise direction of the bed (400); a column (100) on which X-axis guide ways (X1, X2) are formed in the vertical direction perpendicular to the length direction, the column (100) being disposed on the saddle (300) so as to be conveyed in the forward and rearward directions along the Y-axis guide ways (Y1, Y2); and a working shaft (200) disposed at a front side of the column (100) so as to ascend or descend along the X-axis guide ways (X1, X2). The Y-axis guide ways (Y1, Y2) are disposed at positions that are spaced a predetermined distance apart from a lower end of the column (100) in the upward direction.
