Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0016] like Figure 1-2 As shown, a wave-shaped spiral edge reamer includes a cutter head 1, a neck 2 and a handle 3 connected in sequence; it is characterized in that the cutter head 1 includes a knife tooth 4 at the top of the knife head, and a knife tooth 4 The connected side cutting edges 5 and the chip flutes 6 between the side cutting edges; the side cutting edges 5 are helical sinusoidal wave edges; the cutter head 1 is provided with a soft coating; the cutter of the cutter teeth 4 The rake angle α is 2°, and the back angle β is 6°.

[0017] The corrugated spiral blade reamer is made of high-speed steel as a whole.

[0018] The soft coating material on the cutter head 1 is tungsten dis...

Abstract

The invention discloses a wave-shaped helical-edge reamer comprising a bit (1), a neck portion (2) and a handle (3). The wave-shaped helical-edge reamer is characterized in that the bit (1) comprises teeth (4) at the top of the bit, side-cutting edges (5) connected with the teeth (4) and chip spaces (6) formed between the side-cutting edges; the side-cutting edges (5) are helical sine shaped edges; the bit (1) is provided with a flexible coating; anterior angle Alpha of the teeth (4) is 2 degrees, and posterior angle Beta of the teeth (4) is 6 degrees. The wave-shaped helical-edge reamer has the advantages that due to the wave-shaped helical edge structure, cutting is quick, chip breaking performance is excellent, chip removing is smooth, vibration is small, no damages occur to the edge, service life is long, change frequency and cost are low, production efficiency is improved, and the surface roughness of the workpieces to be processed is improved.

Description

technical field [0001] The invention relates to a wave-shaped spiral blade reamer, which belongs to the technical field of numerical control cutting tools. Background technique [0002] The reamer is used to ream the drilled hole on the workpiece, mainly to improve the machining accuracy of the hole and improve the roughness of its surface. It is a tool for finishing and semi-finishing the hole. When the hole to be machined is deep, it will be difficult to remove chips during the process of using the standard reamer. The clogged chips scratch the machined surface, and the surface quality of the hole cannot meet the requirements; The blade of the reamer will cause serious damage to the reamer. Increase the reamer replacement frequency and cost, while reducing processing efficiency. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the object of the present invention is to provide a wave-shaped spiral blade reamer. [0004] In order t...
