Description

Technical Field

[0001] The utility model relates to the technical field of cutting tools, and more specifically, to a milling and drilling composite machining cutting tool. Background Art

[0002] Milling cutters are cutting tools commonly used in milling machines or processing machines to perform milling operations. They remove materials through their fixed feed rate in the machine. Drill bits are cutting tools used by general drills or drilling machines to cut circular holes. The basic principle of the drill bit is to rotate the drill cutting edge, cut the workpiece, and then remove the drill chips through the drill groove. In order to complete most or all processing steps in one clamping, thereby reducing machine tools and fixtures and improving workpiece processing accuracy, milling and drilling composite processing tools are specially used.

[0003] The utility model patent with patent application number 201921560107.6 discloses a milling and drilling composite machining tool, including a cutter head and a threaded hole, wherein a drill bit is provided at the upper end of the cutter head, and the outer wall of the cutter head is provided with a helix angle, a threaded column is connected to the lower end of the cutter head, and a pin hole is provided inside the threaded column, and a tool handle is provided at the lower end of the threaded column. The milling and drilling composite machining tool is provided with a blade, and since both the milling cutter and the drill bit are provided with a spiral rotating structure and can both play a role in chip removal, in order to enable the new type to be used as a milling cutter while drilling holes, blades are provided at both the upper and lower ends of the helix angle, which can be used for cutting materials, and the double-layer design of the blade can make the new type of cutting speed faster.

[0004] However, in actual use, the connecting pin and the semi-threaded column need to be rotated and inserted to complete the installation, which is cumbersome to operate.
