PURPOSE:To make the rigidity uniform and reduce deflection by erecting a column side plate also used as a vertical reinforcing member which reaches directly under a bed bottom surface, directly under a saddle guide rail on the bed, in an electrical working machine such as electrical discharge work. CONSTITUTION:The rigidity of a bed 1 can be improved by erecting a column side plate 12 also used as a reinforcing member in L-shaped integral structure directly under a saddle guide rail 3. Since a reinforcing member part 12B is constituted in an integral structure, the rigidity of the bed 1 along the guide rail 3 can be made uniform. Further, the deflection of the bed 1 due to each weight of the saddle, table, and a workpiece can be reduced. Therefore, the working accuracy can be improved. |
