摘要
The boring machine comprises a framework and a work table adapted to have workpieces secured on it mounted on the framework for displacement in the course of a boring operation. Either one or two bridge structures are mounted on the framework, each carrying at least one spindle head with a tool spindle. The housing of the spindle head is secured on the side of the respective bridge structure, facing the work table. The housing of the spindle head is attached so that the axis of the spindle is offset relative to the axis of symmetry of the bridge structure. The housing of the spindle head is retained against displacement w.r.t. the side of the bridge structure by pins pressure-fitted in the housing. The pins are arranged in the housing of the spindle head so that the plane including their axes is offset relative to a parallel plane including the axes of the spindle.
