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
The present invention relates to field of machining, be specifically related to a kind of chip breaking rose cutter.
Background technology
In machining, rose cutter can be used for working groove, die cavity, arc surface, curved surface etc., in process, the chip of continuous print, orthoscopic can be produced, if these chips are oversize, normally carrying out of processing will be affected, when these chips are wrapped on workpiece or cutter, all can form danger to workpiece, cutter itself and operator.
Summary of the invention
The object of this invention is to provide a kind of chip breaking rose cutter that can carry out chip breaking to the scrap produced.
The present invention is achieved through the following technical solutions: a kind of chip breaking rose cutter, comprise handle of a knife and cutting portion, described cutting portion comprises the radiused cutting edge be positioned on cutting portion end face, cutting portion side face is also provided with helical cutting edge, described radiused cutting edge is connected with helical cutting edge, form chip area between described helical cutting edge, form the spiral helicine ridge extended to cutter head front end between chip area, ridge is provided with the chip breaking mouth for chip breaking.
The axial overall length of described handle of a knife and cutting portion is 50mm-100mm.
The arc angle of described radiused cutting edge is 185 °-205 °.
Described cutting portion is also coated with silicon coating; Improve the waterproof of milling cutter and corrosion resistant performance, improve the surface smoothness of milling cutter.
Beneficial effect of the present invention is: helical cutting edge is provided with chip breaking mouth, the setting of chip breaking mouth, cut into segment, can not be wrapped in cutting the chip produced on workpiece or milling cutter, avoiding chip to the damage of milling cutter; Cutting portion is also coated with silicon coating; Improve the waterproof of milling cutter and corrosion resistant performance, improve the surface smoothness of milling cutter.
