Brown & Sharpe's Automatic Gear Cutter, shown in Fig. 1. is automatic in all its motions, cutting through for each tooth, and revolving the wheel until all the teeth are cut. thus enabling the operator to attend to other work. The indexing is done by a worm and worm-wheel moved by change-gears. The blank being put in place, and the cutter-head adjusted for length of stroke, the wheel is lowered by a screw having a dial reading to thousandths of an inch, until the proper depth of cut is obtained, when the cutter passes through the blank and back by a quick return movement; the wheel is then moved the proper distance for the next tooth, and so on until finished. The cutter-head is adjustable at any angle for cutting bevel-wheels, the degrees being marked on a graduated arc, no other change being required. There is also provision for moving the cutter out of center each way, for cutting bevel-wheels. |
