Abstract:
In a combination machine tool, a hollow spindle c is driven at a comparatively low speed for boring, surfacing, or milling, and an inner spindle q is driven by change 'and differential gearing for transmitting the surfacing feedmotion, and is driven also at a high speed when serving as a drilling or tapping spindle, separate gearing being employed for the feed in this latter case. A driving-shaft j with a double toothed slidable wheel i may transmit motion by gearing h. f, e to the main hollow spindle c, and, by a clutch k, change gear l, m, and gearing o, p, the inner spindle q is rotated to transmit the feed through gearing r, s\ s<2> to a spur-wheel fixed on the feed screw. For drilling or tapping, the spindle q is driven through gearing i, v, x, p, the wheel o being thrown out of gear and the feed being transmitted through gearing y, l, m, z, 2, 3, 4. |
