Description

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1915 edition. Excerpt: ... On the reduced end of arbor i is a nut which serves to clamp the work up against the face of sleeve j. The method of using this arbor is as follows: To chuck the work, sleeve j and its auxiliary members are removed from the spring collet, and the work is screwed Machinery Fig. 14. Section through a "Qrldley" 3Vi-lnch Automatic Turret Lathe Spindle showing Method of chucking Shrapnel Fuse Body onto the nose of arbor i, the position of which is locked by means of a nut on the stem of the arbor. The entire arbor is then replaced in the collet and the machining operations performed on the work. This type of arbor is necessary because of the heavy cutting with the wide forming tool which would tighten the piece on the threaded nose to such an extent that it could not be removed when finished. With this device, it is only necessary to hold the square end of arbor i in a vise, and loosen the work by relieving the nut on the arbor. In g order to facilitate the work, two arbors of this type are provided with each of the machines employed. The operations performed in the first position consist in forming the external diameters with tool k, facing with the side tool, and drilling with drill m. The second turret face is now skipped and the third brought into position, presenting self-open-ing die n which threads the work. At the fourth indexing of the turret slide, the hole is reamed with reamer o and tool p chamfers the face, completing the work. The forming done at the first indexing of the turret slide is performed on slow speed;the spindle speed, however, changes to high at the third position and back to slow just before the fourth position. Machining the Fuse Body.--The fuse body is made from a hot-pressed brass blank, and is machined...show more
