Gap Chucking-Lathe—Fig. 12 shows a gap chucking-lathe made by the Putnam Machine Co. It is an improved tool of great range and capacity, with 25 and 50 in. swing, the gap being 20 ¾ in. long. The cone is balanced, and has four shifts for a wide belt. The head-stock has ground journals with anti-friction metal boxes, which compensate for wear and preserve the original alignment of the live and dead centers. The bed-slider is operated by rack and pinion. |
