Abstract
1,048,571. Milling; grinding. CARL HURTH MASCHINEN - UND ZAHNRADFABRIK. Aug. 7, 1963 [Oct. 19, 1962], No. 31113/63. Headings B3D and B3K. [Also in Division F2] A machine tool comprises a crank mechanism 22 for feeding a milling or grinding tool 16 longitudinally of a workpiece to cut a key-way &c., and a controllable steplessly.variable drive for modifying the natural quasi-sinusoidal velocity of the feed resulting from the crank mechanism. The work to be slotted is mounted on a table 12 adjusted vertically by a screw 13 and the cutter 16 is mounted in an axially-adjustable spindle sleeve 17 on a slide 15 reciprocated by the adjustable crank 20. The crank is rotated by a motor 38 and infinitely-variable gearing 30, 31 controlled by a cam 36 and a lever 35 to cause the speed of cutting of the slot to be constant over the major part of its length. The tool is fed axially at the ends of the strokes. In a modification, the latter feed is driven by a bevel gear on the shaft 18 and change-speed gearing is interposed between the gearing 30, 31 and the worm 24. The axial feed is imposed through a ratchet wheel which can be over-driven by an electric motor. In a further modification, the speed is varied by an electric motor.
