Abstract

The invention discloses a cutting tool. The cutting tool comprises a clamping component and a cutting component capable of being installed on the clamping component, wherein the clamping component comprises a clamping handle part and a clamping head part; the cutting component comprises a cutting head part and a cutting tail part; a clamping bulge is arranged on the end surface of the cutting tail part; an external thread is formed on the clamping bulge; a clamping recession is formed in the end surface of the clamping head part; an internal thread matched with the external thread on the clamping bulge is formed on the clamping recession; an external transition surface located between the external crest and the external root of the external thread is formed at the beginning part of the external thread; the external transition surface comprises an external variable-diameter surface and an external equal-diameter surface; the external variable-diameter surface is connected with the external equal-diameter surface and the external crest; and the distance between the external equal-diameter surface and the external crest in the radial direction of the external thread is r, the internal crest of the internal thread has a constant diameter d1, and the external crest has a constant diameter d2, and r is not less than 0.02mm and not greater than 0.45(d1-d2). The cutting tool disclosed by the invention has the advantages of being stable in structure, high in anti-impact capacity, long in service life and the like.

Description

technical field [0001] The invention relates to the technical field of metal cutting, in particular to a cutting tool. Background technique [0002] Only the cutting part of the cutting tool participates in cutting during the machining process, and the clamping handle does not participate in cutting. In order to avoid the damage of the cutting part and cause the entire cutting tool to be scrapped, and to prolong the service life of the cutting tool, the cutting part of the cutting tool and the clamping tool are usually combined The shank is set separately, that is, the cutting part and the clamping shank are connected by ordinary threads to realize repeated loading and unloading of the cutting part on the clamping shank. [0003] However, with the development of metal processing technology, the length-to-diameter ratio of cutting tools is increasing, which requires cutting tools to have higher strength and rigidity. It is made of cemented carbide or materials with propertie...
