US 6,333,480 B1 · Wire electric discharge machining apparatus

Abstract

In order to improve ease of assembly and machining accuracy of a wire electric discharge machine, the present invention constructs a column and a lower support assembly to be separated, and configures the lower support assembly to have a structure integrally composed of a proximal portion having the same sectional shape as a sectional shape of the column, and a central projecting portion that projects from a center of a bottom surface of the proximal portion to support a lower arm. Furthermore, the lower arm is attached to the central projecting portion of the lower support assembly, while a Y-axis guide guided by a Y-axis guide rail of a Y-axis guiding mechanism, for example, is attached to the bottom surface of the proximal portion of the lower support assembly. Then the proximal portion and a bottom surface of the column are connected by bolts.
