Embodiment 2

[0051] This embodiment provides a kind of ball cutter, adopts the processing method of above-mentioned ball cutter, such as Figure 3-Figure 4 As shown, the ball cutter includes a handle 2 and a cutting part 1. The cutting part 1 is arranged at one end of the handle 2. The cutting part 1 includes a body 11 and a first cutting edge 1111. The body 11 is provided with a helically extending flute. 116, the two first cutting edges 1111 are arc-shaped and symmetrically arranged on the end of the body 11 away from the handle 2, the two first cutting edges 1111 intersect to form a chisel edge 112, and the chisel edge 112 is provided with an oblique linear chisel edge Line 1121.

[0052] Such as Figure 5 As shown, the ball cutter provided in this embodiment has a neat oblique linear chisel edge line 1121 on the chisel edge 112 between the two arc-shaped and symmetrical first cutting edges 1111, which enhances the surface finish of the workpiece to be processed. effect, thereby impro...

Abstract

The invention belongs to the technical field of cutting tools, and discloses a ball cutter machining method and a ball cutter. The machining method of the ball cutter comprises the steps that firstly, rough machining is conducted on a bar, and a hemispherical blade part is formed at one end of the bar; then the bar is polished, and a chip groove is formed; and finally, the semispherical blade part is polished in the direction from the maximum cross section to the minimum cross section, so that a first cutting edge and a chisel edge are formed, and the chisel edge is provided with an oblique linear chisel edge line. According to the machining method of the ball cutter, in the forming machining process of the ball cutter, the machining path is simple, it can be guaranteed that in the machining process of the to-be-machined part through the ball cutter, the surface roughness of the surface of the to-be-machined part is reduced, meanwhile, the machining time is shortened, and the machining efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of cutting tools, in particular to a processing method of a ball cutter and the ball cutter. Background technique [0002] When processing the ball cutter in the prior art, it is necessary to select a suitable bar, and use a grinding wheel to rough the bar, so that one end of the bar forms a hemispherical cutter head, and then place the bar on the grinder for chip removal After the flute is opened, the grinding wheel is used to process from the top to the bottom of the hemispherical cutter head to form the cutting edge and chisel edge. This processing method is easy to form irregular chisel edge lines on the chisel edge. The chisel edge line leads to poor processing rigidity of the ball cutter during the processing of the product to be processed, poor surface accuracy and smoothness of the processed workpiece, and low processing efficiency. [0003] Therefore, urgently need a kind of processing method of ba...
