Problems solved by technology

[0002] Turning tools need to be used in turning processing. The current turning tools are generally made by fixing the blade on the handle, and the mutual positional relationship between the blade and the handle is also fixed after being made, and cannot be adjusted any more. Due to blade wear and other reasons, there is often a need to fine-tune the blade
In addition, the existing turning tools lack chip breaking ability, and the chips are often wrapped around the surface of the tool or workpiece, scratching the machined surface

Abstract

The invention relates to the field of tools used for lathes or boring mills, in particular to a turning tool capable of realizing chip breaking. The turning tool capable of realizing chip breaking comprises a tool frame (1), and is characterized in that the turning tool further comprises a blade (2), wherein the tool frame (1) is a convex polygon, the number of sides of the convex polygon is not less than three, all the sides are equal, and at least one vertex angle of the tool frame (1) is cut inwards to form a blade groove (12); and the blade (2) comprises a cutting portion (21) and a chip breaking portion (22), the front portions of the top surfaces of the cutting portion (21) and the chip breaking portion (22) are separately formed by smoothly connecting the two ends of a section of inferior arc with a straight section, the front portion of the cutting portion (21) is a cutting edge (211), and the front end of the chip breaking portion (22) is an oblique plane. The turning tool capable of realizing chip breaking is simple in structure, convenient to use, good in chip breaking effect and high in adaptability.

Description

technical field [0001] The invention relates to the field of cutting tools used in lathes or boring machines, in particular to a chip-breaking turning tool. Background technique [0002] Turning tools need to be used in turning processing. The current turning tools are generally made by fixing the blade on the handle, and the mutual positional relationship between the blade and the handle is also fixed after being made, and cannot be adjusted any more. Due to blade wear and other reasons, there is often a need for fine-tuning of the blade. In addition, the existing turning tools lack chip breaking ability, and the chips are often wrapped around the surface of the tool or workpiece, scratching the machined surface. Contents of the invention [0003] In order to overcome the defects of the prior art and provide a cutting tool with simple structure, convenient use, flexible adjustment and strong adaptability, the invention discloses a chip-breaking turning tool. [0004] Th...
