Double-faced indexable four-cutting-edge milling insert

Abstract

The invention relates to a double-faced indexable four-cutting-edge milling insert. The double-faced indexable four-cutting-edge milling insert comprises a base body and four welding sheets arranged on the base body in a staggered mode. A cutting edge is arranged on each welding sheet, each cutting edge comprises a main cutting edge and an auxiliary cutting edge, the cross points of the main cutting edges and the auxiliary cutting edges are tool noses, and two tool noses of the cutting edges are arranged on each of the obverse side and the reverse side of the base body; and conical surfaces used for being matched with a height adjusting device are symmetrically arranged on the upper side surface and the lower side surface of the base body, and a mounting hole is formed in the center of the base body. According to the double-faced indexable four-cutting-edge milling insert, an adjusting mechanism of the milling insert is simplified, only the conical surfaces need to be arranged on the milling insert, the double-faced milling insert is designed, and the effect that the cutting edge number is doubled is achieved; and one milling insert has the four usable cutting edges, the milling insert can be used for 4 times, meanwhile, the tool noses are located on the obverse side and the reverse side of the base body correspondingly and arranged in a staggered mode, so that the cutting edges of the welding sheet parts give way to each other, and interference is prevented.

Description

Technical field [0001] The invention relates to the field of milling blades, in particular to a double-sided indexable four-edge milling blade. Background technique [0002] In metal cutting processing, the finishing of face milling has always been a key and important technical point. In order to pursue high surface quality requirements, PCD tools are generally used for milling in non-ferrous metal processing centers, and milling blades are generally used in cutting processing centers. They are all consumables, and it is usually expected that the milling insert has as many cutting edges as possible. Because PCD face milling cutters have strict requirements for the axial runout of the cutter head, the inserts need to have a height adjustment unit, so most of the current PCD The milling inserts are all single-sided design, with one or two cutting edges, which can be used less frequently, and the economy is not good. Summary of the invention [0003] The purpose of the present inven...

[0002] In metal cutting processing, the finishing of face milling has always been a key and important technical point. In order to pursue high surface quality requirements, PCD tools are generally used for milling in non-ferrous metal processing centers, and milling inserts are generally used in cutting processing centers. They are all consumables. It is usually expected that milling inserts have as many cutting edges as possible. Since PCD face milling cutters have strict requirements on the axial runout of the cutter head, the inserts need to have a height adjustment unit. Therefore, most of the current PCD Milling inserts are designed on one side, with one or two cutting edges, which can be used less frequently and are not economical
