Abstract

928,294. Milling-cutters. RICHARD LLOYD Ltd. April 4, 1962 [May 10, 1961], No. 16948/61. Class 83 (3). A milling cutter comprising a circular body 1 having transverse slots 2 in its peripheral portion, is provided with cutting units each comprising a holder of L-shaped section adapted to be fixed within a slot 2 with the shorter arm 3<SP>1</SP> of the L overhanging the front face of the body 1, the holder carrying a clamp for fixing a readily removable throw-away cutter tip 4 to the holder. The longer arm or shank 3 of the holder is fixed in the slot 2 in the body 1 by a wedge 10 operated by screws 11 and provided with an extracting screw 13. The cutter tip 4 is held in a recess 5 in one lateral face of the arm 3<SP>1</SP> of the holder by a loose clamping jaw 6 connected to the holder by a screw 7. In a modification, Fig. 6, the cutter tip 4 is adjusted and set in relation to the holder by a locking bar 14 slidably disposed adjacent the holder 3, between the holder and the face of the wedge 10, and operable by a screw 16 inserted into a tapped hole in the holder shank and having a head 16 which engages a recess in the side of the adjusting bar. The bar 14 is ground to a taper section with its thicker edge presented radially downwards and is provided with a right-angled notch to engage the blade. In another modification which provides for a similar adjustment, the shank of the holder is utilized as a wedge.
