Abstract
11,293. Strong, E. C. May 14. Milling.-Articles to be fluted, especially twist drills, are supported by a row of headstocks mounted on a sliding table A, Fig. 2. The grooves are cut by a gang ot cutters F<1>, and the work is supported by rests H, which are independently adjustable by plates- J and screws K to compensate for change in cutter diameter due to regrinding &c. The plates J are preferably pivoted so that the thickness of web increases slightly towards the drill shank. In a modification, the plates are supported by three set-screws, one at one end, and two at the other geared together and having right and left handed threads ; more than three screws may be used. In a further modification, the plates J are dispensed with, and the rests H have lifting- screws bearing directly on the table A, which is then arranged at the required angle to produce the desired thickening of web. The headstocks are then mounted so as to be movable in a vertical plane. Movable headstocks may be employed in all cases, to prevent undue stress on the drill.
