Description

Technical Field

[0001] The utility model relates to a multi-layer composite T-shaped tool, specifically a tool for machining mechanical parts, and belongs to the technical field of tools. Background Art

[0002] The multi-layer composite T-type tool has an ingenious structural design, combining multiple cutting functions in one tool. Its basic principle is to achieve the goal of completing multiple processes in a single machining process by providing multiple cutting edges or cutting layers on the same tool. The multi-layer composite T-type tool is one of the important tools in modern machining. Its high efficiency, high precision and wide adaptability make it play a vital role in the machining of mechanical parts.

[0003] In the prior art, a T-shaped tool, such as that disclosed in Publication No. CN206662364U, comprises a shank and a cutting section. One end of the shank is connected to the cutting section, forming a T-shape. The cutting section comprises six helical teeth, six front teeth, and six rear teeth, with the helical teeth connected between the front and rear teeth. This tool structure is more stable, extends the tool's service life, and meets customer needs.

[0004] Although the above technical solution ensures that the tool structure is more stable and improves the service life of the tool, its tool can only perform cutting processing on the workpiece and cannot perform chamfering processing on the workpiece, resulting in the need to replace the tool when the workpiece needs chamfering, and its practicality is poor. In view of this, a multi-layer composite T-shaped tool for machining mechanical parts is provided to overcome the above defects. Utility Model Content
