Abstract: A horizontal boring mill for machining work at a high rate. The boring mill includes a massive boring bar which carries intermediate its end the boring-tool holder from which boring tools extend radially. The boring bar is rotated by a first drive of sufficient power to enable the boring tool to take a deep cut in the work at a high rate. The boring bar is rotatable on bearings of substantial area; a bearing between the first drive and the bar and bearings on each side of the work. The bar, the first drive and the bearing between the first drive and the bar are moved along the bed of the boring mill by a second drive so that the boring tool engages and cuts the work. The other bearings are secured to the bed and the bar is moved through them. Each bearing on each side of the work carries a facing tool which is rotatable by the bar as the bar is rotated but is not movable with the bar. These bearings may be adjustably secured along the bed so that the facing tool is in position to face the ends of the work.
