Abstract
631,438. Making drills, cutters and taps. SMITH, S. Sept. 3, 1947, No. 24292. [Classes 83 (ii) and 83 (iv)] Forging helical &c. grooves.-In a method of making fluted drills, bits, taps, reamers, &c. a rod is subjected to hammer blows from radially displaced dies. The rod e passes axially through a stationary hollow spindle a having slots for the radial dies d which are actuated by rollers b located between a fly-wheel c and the spindle a, without the use of a cage, and driven in a circular path by the fly-wheel. The dies are adjusted by wedges d<SP>1</SP> as described in Specification 570,723. Helical flutes may be obtained by having dies with helical ribs and rotating the work as it passes through the dies. Any number of flutes may be formed according to the number of radial dies used and two-fluted tools may be made with four dies, one pair of opposite dies producing the flutes and the other pair maintaining the required size and shape. The square end of a tap may be formed in a similar manner, the thread of the tap being subsequently milled or ground.
