  • Patent number: 4799835
    Abstract: The present invention is an improvement in a machine tool having a pedestal, a vertical column fixedly mounted on the pedestal, a workhead mounted on the column, an elevating mechanism for elevating the workhead along the column, and a worktable provided the pedestal. The workhead carries a spindle, a motor for driving the spindle, a reduction gear and a longitudinal feed gear. According to the present invention, another worktable is provided at a different height from the first worktable and at a position displaced by at least 90 degrees from the first worktable with respect to the column.
