Abstract
An indexable insert milling cutter having multiple round inserts located in staggered individual isolated pockets formed in the annular periphery of the cutter body. Each insert is trapped in its pocket with only a small fraction of the cutting edge projecting beyond the periphery of the body. A chip clearance wall extends outwardly from the cutting face of the insert to the periphery of the body.
Claims28
An indexable insert milling cutter comprising an annular cylindrical body, a plurality of individual insert pockets formed in the cylindrical periphery of said body, each of said pockets having a seat for holding an insert with its cutting face in a substantially axial plane modified to the extent of any axial and radial rake angles which are the same for every insert, and a minor portion of its cutting edge projecting beyond said periphery, each pocket having a chip clearance wall associated therewith, said wall providing chip clearance space projecting from the entire cutting face to the periphery of said body, each pocket with its chip clearance wall being substantially isolated from every other pocket by surrounding cylindrical periphery of said body, and said insert pockets being uniformly spaced in overlapping cutting relationship in an axial direction and angularly spaced in a circumferential direction on a continuous helical path for progressive cutter entry in milling a workpiece.
A milling cutter comprising an annular body constructed for mounting a plurality of individual cutting elements on its periphery, with a cutting edge of each element extending beyond the periphery, and on a continuous helical path, with equal angular spacing, within a range of 91.degree. to 100.degree..
