Embodiment Construction

[0011] refer to figure 1 , a chip breaking ball end milling cutter, comprising a tool holder 1 and a cutting portion 2, the cutting portion 2 includes a circular cutting edge 6 on the end face of the cutting portion, and a helical cutting edge is also provided on the peripheral surface of the cutting portion 2 Edge 3, the arc-shaped cutting edge 6 is connected with the helical cutting edge 3, and a chip removal groove 5 is formed between the helical cutting edges 3, and a spiral shape extending toward the front end of the cutter head is formed between the chip removal grooves. The protruding ridge 7 is provided with a chip breaking port 4 for chip breaking.

[0012] The total axial length of the tool handle 1 and the cutting part 2 is 50mm-100mm.

[0013] The arc angle of the arc-shaped cutting edge 6 is 185°-205°.

[0014] The cutting part 2 is also coated with a silicon coating; the performance of waterproof and corrosion resistance of the milling cutter is improved, and t...

Abstract

The invention discloses a chip breaking ball-end milling cutter. The chip breaking ball-end milling cutter comprises a cutter handle and a cutting part, wherein the cutter handle and the cutting part are integrated; the cutting part comprises an arc-shaped cutting edge which is positioned on the end surface of the cutting part; spiral cutting edges are also formed on the peripheral surface of the cutting part; the arc-shaped cutting edge is connected with the spiral cutting edges; a chip discharging groove is formed between every two spiral cutting edges; a spiral ridge which extends to the front end of a cutter head is formed between every two chip discharging grooves; a chip breaking opening used for breaking a chip is formed in each spiral ridge; through the arrangement of the chip breaking openings, the cutting chips generated by cutting can be cut into small sections and cannot wind around a workpiece or the milling cutter, so that the damage to the milling cutter caused by the cut chips is avoided; a silicon coating also coats the cutting part; the waterproof performance and the carrion resistance of the milling cutter are improved; the surface finish degree of the milling cutter is improved.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a chip breaking ball end milling cutter. Background technique [0002] In mechanical processing, ball end milling cutters can be used to process grooves, cavities, arc surfaces, curved surfaces, etc. During the processing, continuous and linear chips will be generated. If these chips are too long, it will affect the processing. Proceeding normally, when these swarf entangles on the workpiece or tool, it poses a danger to the workpiece, the tool itself and the operator. Contents of the invention [0003] The object of the present invention is to provide a chip-breaking ball end mill capable of chip-breaking generated waste chips. [0004] The present invention is achieved through the following technical solutions: a chip-breaking ball end milling cutter, comprising a tool holder and a cutting portion, the cutting portion includes an arc-shaped cutting edge on the end surfac...
