Embodiment 1

[0014] Such as figure 1 As shown, the thread milling cutter of this embodiment includes a shank 1 and a blade 2. The key point is that the blade 2 is composed of a milling edge 3 for milling a bottom hole and a forming edge 4 for milling a thread. end of section 2.

[0015] Further, the forming edge 4 and the milling edge 3 share the chip removal groove 5, so that the debris generated when milling the bottom hole will not accumulate at the forming edge 4, resulting in a decrease in thread quality.

[0016] Further, there are multiple milling edges 3, and the arc angles of each milling edge 3 are different, so as to be suitable for different kinds of materials.

[0017] When the above-mentioned thread milling cutter is milling threads, the milling edge 3 is used to remove the allowance of the workpiece first, and the bottom hole of the thread is milled out. As the milling edge 3 deepens, the forming edge 4 mills the thread out of the bottom hole, and there is no need to change...

Abstract

The invention aims to provide a thread milling cutter. When threads are milled, the work efficiency of machining the threads can be effectively improved, and the production cost can be reduced while the product quality is guaranteed. The thread milling cutter comprises a handle part and a blade part, and is characterized in that the blade part consists of a milling blade for milling bottom holes and a forming blade for milling the threads, wherein the milling blade is positioned on the end part of the blade part. When the thread milling cutter is used for milling the threads, the allowance of a workpiece is removed and thread bottom holes are milled by the milling blade, and along with the advance of the milling blade, the threads in the bottom holes are milled by the forming blade; the cutter is not required to be changed in the whole process, so that cutter changing, cutter installing and cutter setting time is shortened; the product quality is guaranteed and the production cost can be reduced.

Description

technical field [0001] The invention belongs to the technical field of cutter manufacturing, and in particular relates to a thread milling cutter. [0002] Background technique [0003] When the traditional milling cutter mills the thread, first use the drill bit to process the bottom hole of the thread, and then use the milling cutter to mill the thread. The failure of the drill bit and the milling cutter to be coaxial results in unstable product quality and increases production costs. [0004] Contents of the invention [0005] The object of the present invention is to provide a thread milling cutter, which can effectively improve the working efficiency of thread processing when milling threads, and can reduce production cost while ensuring product quality. [0006] The thread milling cutter of the present invention includes a shank and a blade, the key point is that the blade is composed of a milling edge for milling a bottom hole and a forming edge for milling a thr...
