HORIZONTAL FLOOR BORING AND MILLING MACHINE.
We illustrate herewith a new horizontal floor boring, drilling and milling machine, built by the Newton Machine Tool Works, of Philadelphia. These machines are designed for all classes of boring, drilling and milling, and they cover a greater variety of work than any other class of machine tools. Many operations can be finished on this machine, by the use of a milling cutter, that would require a very large and expensive planing machine for the same work, besides doing the work more rapidly. Many operations, especially where a rotary table is used, can have the entire work finished with one clamping, doing the boring, drilling, tapping and most of the finishing with one setting. This machine, as can be seen by the illustration, is made exceptionally strong, the upright being proportioned to withstand heavy work. The feed mechanism for the bar has many suitable changes for fine roughing cuts to fast finishing cuts. The same feed mechanism controls the feed of the head on the upright and of the upright on the column for milling. The head is counterweighted and has a quick movement on upright, while the upright has a quick power movement on bed, all of which the operator can control without moving from his work. The boring-bars of these machines are all large, with a long, heavy feed.
They are built in three sizes. The No. 1 has a boring-bar 4 inches in diameter and an automatic feed of 32 inches; the No. 2 has a boring-bar 5 ½ inches in diameter and an automatic feed of 48 inches; the No. 3 machine has a boring-bar of 7 inches in diameter and an automatic feed of 60 inches.
Machines of this description can be made to any desired height or length. The outside support for the bar, as shown, can be clamped in any position on the work-table and has a separate adjustment for convenience in setting the support central with the boring-bar. The boring-bar of the machine is driven with a triple phosphor-bronze worm-wheel with a hardened steel worm, which insures a steady, even motion and gives great power to the
cut. |
