Newton Nut-Facing Machines consist of a nut-facing machine, for facing the end of the nuts, and a nut-milling machine for finishing the sides. These tools are in use in many locomotive and nut and bolt works. The nut-facing machine. Fig. 8, may be used in place of a lathe or ordinary facing machine. The tools for facing can be made 12 in. long, and the profiles desired are planed or milled lengthwise on their faces. An important feature of this tool is a device for reaming the burr from the thread. A small tool is held in the carriage and operates on the nut the some time it is being faced ; requiring only one operation to face the nut and ream the burr from the thread. The double-headed nut-milling machine, Fig. 4, has two independent head stocks each provided with an adjustable cutter, the teeth of which are made of 3/8 in. square steel, and are 4 in. in length. The teeth are placed in two rows or circles in the cutter-head, and are held in position by set-screws. The first row acts as an advance or roughing cutter, and the inner row, which projects 1/64 in. further, takes the finishing cut. There is a device provided for setting the nuts in position on the arbors, so that they will come exactly square with the face of the cutter when they are placed for milling, and no further setting is required. The machine mills two sides of from 12 to 20 nuts at once, depending on the thickness of the nuts. |
