The machine in Fig. 18 provides sixteen changes of feed, ranging from 0.006 inch to 0.300 inch per revolution of cutter, and this particular feed-changing device permits changing the rate of feed through the whole series of changes while the machine is working. This is accomplished by bringing the different combinations of gears, formed by a fixed cone of gears and a sliding gear, into mesh radially by a simple movement of the levers shown over the feed-box at the rear of the machine, and the rate of feed is at all times indexed by the position of the lower lever.
It has power feed for the table in all directions, namely, lengthwise of the table, crosswise in line with the spindle, and vertically, the feed in all directions being under control of a reversing lever. The method of swiveling the table is the same in principle on all universal millers, and provides sufficient angularity to cut spirals up to and including 45 degrees. |
