Embodiment 1

[0031] Example 1. A kind of microstructure cemented carbide turning blade for cutting superalloy GH4169, its composition is as follows figure 1 As shown, including the rake face 1, the edge of the rake face 1 is provided with a main cutting edge 2, and the cutting edge of the rake face 1 is provided with a microgroove 5 near the region 4; the microgroove 5 is asymmetrical and integral J-shaped microstructures with unequal widths and unequal depths (such as figure 2 shown).

[0032] Aforesaid microgroove 5 (as Figure 3-5 As shown), the section on the rake face 1 is asymmetrical curve, the bottom surface 7 of the microgroove 5 is flat, and the maximum depth H of the microgroove 5 is 0.27-0.34mm.

[0033] The length L of aforementioned microgroove 5 is 2.15~2.66mm; The maximum width W of microgroove 5 (as figure 2 Shown) is 0.89 ~ 1.21mm.

[0034] The minimum distance T (such as figure 2 shown) is 0.06~0.09mm.

[0035] The connection form between the outer edge 3 of the ...

Abstract

The invention discloses a microstructure hard alloy turning blade cutting high temperature alloy GH4169. The microstructure hard alloy turning blade cutting the high temperature alloy GH4169 comprises a front blade face (1). The edge of the front blade face (1) is provided with a main cutting edge (2). A microgroove (5) is formed at the position of a cutting edge near area (4) of the front blade face (1). The microgroove (5) is of a dissymmetrical J-shaped microstructure which is equal in width and different in depth on the whole. The microstructure hard alloy turning blade cutting the high temperature alloy GH4169 has the advantages of lowering the cutting temperature and improving the durability of a tool.

Description

technical field [0001] The invention relates to a cutting tool used in the field of cutting processing, in particular to a microstructure hard alloy turning blade for cutting superalloy GH4169. Background technique [0002] Cutting is the main means of material removal in the machinery manufacturing industry, and the quality of cutting tools directly affects the efficiency and quality of cutting. In the cutting process, the cutting edge is the main part of removing material, the cutting edge and the rake face area near the cutting edge (the near area of ​​the cutting edge refers to the small area on the rake face of the tool close to the cutting edge, such as figure 2 The area surrounded by the middle dotted line) has the worst working environment, and its structure is directly related to the durability of the tool, the efficiency of machining and the quality of machining, so the reasonable design of the cutting edge and the near-field structure of the cutting edge is partic...
