Description

Technical Field

[0001] This utility model relates to the field of cutting tool technology, and in particular to a cutting tool for CNC machining of the outline of a mobile phone frame. Background Technology

[0002] As mobile phone appearances continue to evolve and designs change, the demands on CNC machining technology are also increasing. In recent years, more and more mobile phone mid-frames have added decorative pieces to their top edges. Therefore, during CNC machining, an additional U-groove needs to be milled for attaching the decorative piece. Currently, when machining the U-groove using CNC side holes, uneven heights occur on the left and right sides of the U-groove. This results in uneven decorative pieces on the finished product, causing discomfort and a rough feel. The reason is that when machining the U-groove using CNC, the probe probes the end face of the display screen. This misaligns the coordinates of the U-groove with the overall shape, leading to inconsistent depths. Therefore, a new tool for machining the CNC outline of mobile phone mid-frames has been designed. Utility Model Content

[0003] The purpose of this utility model is to provide a CNC machining tool for the outer contour of a mobile phone frame, which addresses the shortcomings of the existing technology. This tool has a novel design and simple structure, does not require tool replacement, and can simultaneously machine the outer contour of the frame and the U-shaped groove, greatly improving machining efficiency.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution.

[0005] A tool for CNC machining the outline of a mobile phone frame includes a tool body, a cylindrical tool holder at the upper end of the tool body, a tool head at the lower end of the tool holder, a U-groove cutting edge at the upper end of the tool head, and an arc-shaped cutting edge at the lower end of the U-groove cutting edge.

[0006] The tool body is made of imported AF material.

[0007] The U-groove cutting edge is perpendicular to the handle.

[0008] A chamfer R is provided between the U-groove cutting edge and the outer shape cutting edge.

[0009] The beneficial effects of this utility model are as follows: The CNC machining tool for the outer contour of a mobile phone frame, as described in this utility model, includes a tool body, a cylindrical tool holder at the upper end of the tool body, and a tool head at the lower end of the tool holder. The upper end of the tool head has a convex U-groove cutting edge, and the lower end of the U-groove cutting edge has an arc-shaped outer cutting edge. By providing a convex U-groove cutting edge at the upper end of the tool head and an arc-shaped outer cutting edge at the lower end, this utility model allows for simultaneous machining of the outer contour of the frame and the U-groove without the need to change tools, greatly improving machining efficiency. Therefore, this utility model has the advantages of novel design, simple structure, and the ability to simultaneously machine the outer contour of the frame and the U-groove without the need to change tools, thus significantly improving machining efficiency.
