Problems solved by technology

However, there are also some problems in the design of this cutting edge. When the cutting insert is installed on a tool body with other diameters, especially when the diameter of the tool body differs greatly from the design diameter, the cutting edge is difficult to rotate with the tool body. The cylindrical surfaces coincide, or partially co

Embodiment Construction

[0034] Such as Figure 3 to Figure 8 As shown, the indexable insert for face milling of the present invention includes an insert body 1 surrounded by an upper surface 13, a lower bottom surface 12, two end surfaces 14 connecting the upper and lower bottom surfaces, and two side surfaces 6. The insert body 1 It is formed by pressing cemented carbide powder, and then sintering and shrinking at high temperature in a special sintering equipment. The center of the blade body 1 is provided with the blade center hole 5 perpendicular to the bottom surface 12 of the blade, and the intersection line between the upper surface 13 of the blade body 1 and the two side faces 6 forms a pair of main cutting edges 2, and the upper surface 13 of the blade body 1 and the The intersecting lines of each end face 14 all form the wiper edge 4 and the minor cutting edge 11, and the wiper edge 4 and the minor cutting edge 11 are connected by a recessed part 15, which can reduce the minor cutting edge 1...

Abstract

The invention discloses an indexable cutting tip for a face milling process,, comprising an upper surface, a bottom surface and a cutting tip body surrounded by the two end faces connecting the upper and bottom surfaces and the two side faces. The center of the cutting tip body is equipped with a cutting tip center hole for installing compression screw. An intersection line of the upper and the two side faces is formed to a couple of main cutting edge which is connected by at least three curvilinear cutting edges heaving outward relative to the cutting tip central hole. Each section of the curvilinear cutting edge is formed by crossing the surface and the relative cutting wheeling cylindrical surface respectively. And the two adjacent curvilinear cutting edges are connected by smooth transition. The indexable cutting tip for a face milling process has the advantages of being applied to many kinds of tools with cutting radius of gyration, guaranteeing the precision of the face milling processing and improving the linking cutter marks.

Description

technical field [0001] The invention relates to mechanical cutting technology, in particular to an indexable insert for face milling. Background technique [0002] When the existing commonly used indexable inserts process vertical walls with high precision requirements, the processed walls are not completely vertical, and sometimes the difference is large, especially when the same insert is installed on tool bodies with different diameters. Big. The Chinese patent No. ZL90102672.7 discloses a cutting insert for milling tools, the main cutting edge of which is obtained by the intersection of an axially inclined plane and a cylindrical surface of constant diameter. When on the same tool body, the cylindrical surface obtained by the rotation of the cutting edge can be well overlapped with the rotating cylindrical surface of the tool body. Using such a helical cutting edge, a vertical wall surface with good machining accuracy can be obtained. However, there are also some probl...
