Description
Technical Field
[0001] This utility model belongs to the field of alloy drill bit processing technology, and in particular relates to a multi-axis tool holder for alloy drill bit processing. Background Technology
[0002] Carbide drill bits are tools commonly used in drilling operations, primarily composed of cemented carbide (such as tungsten carbide, cobalt-based alloys, etc.) and other metallic materials. Due to the extremely high hardness and wear resistance of cemented carbide, carbide drill bits can maintain their sharpness at higher cutting speeds and for longer periods compared to traditional high-speed steel drill bits.
[0003] During the machining process, the drill bit needs to be cut on the outside of the blank shank and then drilled internally to form the drill bit handle. This step involves clamping the front end of the drill bit on the machine tool and then pushing the cutting tool and drill bit towards the blank shank for machining through a single-axis pushing mechanism. However, in the existing method, the external cutting and internal drilling steps are separated, which obviously reduces efficiency. Since two clamping operations are required, there is a certain error, which ultimately affects the quality and consistency of the drill bit.
[0004] To address the aforementioned issues, this application proposes a method for machining multi-axis tool holders using alloy drill bits. Utility Model Content
