Large grain diamond directional arrangement milling cutter

Abstract

The invention provides a milling cutter with large-size diamonds arrayed in an oriented manner, and belongs to the technical field of ultrahard tools. The milling cutter structurally comprises three parts, namely, a cutter handle (1), a cutter disc (2) and a diamond tool nose (3). The diamond tool nose (3) is formed by arraying the large-size monocrystal diamonds on the cutter disc (2) in an annular and oriented manner. According to the milling cutter, points and edges of the monocrystal diamonds are effectively used as cutting edges, the milling cutter can be used for face machining and hole machining of ultrahard materials, and when rough machining is conducted, the milling cutter has the beneficial effects of being large in removal amount, high in efficiency, durable in use, good in profiling and the like; and when fine machining is conducted, the milling cutter has the beneficial effects of being high in precision, high in surface smoothness degree, good in profiling and the like.

Description

technical field [0001] The invention belongs to the technical field of superhard cutting tools, in particular to a diamond milling cutter. Background technique [0002] Ceramic composite materials represented by aluminum-based ceramic composite materials and carbon fiber ceramic composite materials have attracted more and more attention due to their relatively good comprehensive performance, and have been successfully used in industrial manufacturing, especially in the development of aviation and aerospace equipment. Good for a wide range of applications. However, these special composite materials have the characteristics of high toughness and high hardness. At the same time, the processing difficulty is significantly increased. It is difficult to achieve effective precision machining with conventional alloy tools and PCD diamond tools, and the tool wears quickly, which affects the processing effect. Therefore, higher requirements are put forward for the cutting tools for m...

Patent application CN104551171A proposes to use ultra-fine-grained cemented carbide rods as the base material to prepare milling cutters, which are mainly used for processing difficult-to-machine materials in printed circuit boards, with small processing removal and low efficiency, and the cutter can only achieve ceramic substrates Rough machining of composite materials, finishing machining cannot be achieved

Patent application CN105970071A proposes a weakly inlaid diamond milling cutter. The diamond particles are small, the diamonds are randomly arranged, there is no sharp cutting edge, the processing efficiency is low, and it is only used for milling alumina ceramics, which is not suitable for toughness and hardness. High material processing, the processing material is single, and cannot meet the processing needs of various ceramic matrix composite materials
