Embodiment Construction

[0026] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0027] The invention provides an indexable milling insert for side wall processing in view of the problems that the vertical accuracy and smoothness of the processed side surface of the existing insert are not high, and the cutting marks obviously affect the processing efficiency under the condition of large cutting depth.

[0028] like figure 1 , Figure 4 and Figure 5 As shown, the embodiment of the present invention provides an indexable milling insert for side wall processing, including an upper top surface 2, a lower bottom surface 3 and a Two end surfaces 4 and two side surfaces 5 surround an approximately cuboid blade main body 1, said blade main body 1 is provided with a central hole 6 at its axisymmetric center, said upper top surface 2 and t...

Abstract

The invention provides a rotatable milling blade for sidewall machining. The milling blade comprises an upper top surface, a lower bottom surface, two end surfaces connected with the upper top surfaceand the lower bottom surface, and an approximately cuboid blade main body defined by two side surfaces; the upper top surface and the two side surfaces extent at respective curvatures and intersect,and a first main cutting edge and a second main cutting edge are formed; the first main cutting edge is fitted on a first cutting rotating cylindrical surface with the diameter being D and orderly extends on the first cutting rotating cylindrical surface; and the second main cutting edge is fitted on a second cutting rotating cylindrical surface with the diameter being d and extends orderly on thesecond cutting rotating cylindrical surface. The vertical precision and the surface smoothness of a machined side surface at different cutting depths can be met, the cutting quality of the side surface is improved, and the cutting efficiency is improved.

Description

technical field [0001] The invention relates to the field of metal cutting, in particular to an indexable milling insert for side wall processing. Background technique [0002] In today's metal cutting processing field, the machining accuracy of the side of the part is required to be higher and higher. The machining accuracy of the side is mainly reflected in two aspects, one is the surface finish of the side, and the other is the vertical accuracy between the side and the machine tool datum. In an existing indexable insert for milling, the main cutting edge is formed by connecting multiple sections of curved edges that protrude outward relative to the center hole of the insert. When the insert is installed on a tool body with different cutting radius of rotation, it can ensure that the cylindrical surface obtained by at least one section of the curved edge rotating around the tool body rotation axis coincides with the cutting rotating cylindrical surface forming the curved ...
