TH90449B - Cutting inserts for milling cutter - Google Patents

Abstract

The fully positioned square cutout inserts have four lateral surfaces connected to the Two end surfaces at the cross section of each side surface and the end surface are edges. Primary cut over the insert corner And along the line of one side surface in a downward direction towards the middle plane of the notched part from the same insert corner And along the lines of the lateral surfaces that are close to each other In an upward direction away from the center plane To be raised above the lean surface of the distal surface Related Cutting insert shape And the insert socket, which is mounted into the insert, has the appearance of The primary cut has a positive axial (helix) angle while the insert has a negative axial relative angle. Peaks for providing axial clearance And the negative radial comparison angle for allocating There is a distance along the radial.

1.Two-end positioning cutting inserts (100) that include The first (102) and second (104) are essentially square ends, which face in opposite directions. Where each end surface has an associated lean surface (108) and four associated insert angles (106), four lateral surface corners (112A, 112B, 112C, 112D). That connect the first end surfaces and at Two for forming, eight edges come up. Each edge is composed of a primary cutting edge (120).
