The feed per tooth of the high-feed milling cutter can reach about 3mm at present, which can be increased by more than ten times compared with the traditional face milling cutter, but at the same time it is at the expense of the depth of cut, because the high-feed milling cutter The design principle is to set the cutting edge at the bottom of the blade and the bottom surface of the cutter head at a certain angle, and transform the radial force of the ordinary milling cutter into the axial force of the high-feed milling cutter, so as to achieve a large Feed processing, so the high-feed milling cutter mainly relies on the bottom cutting edge for cutting, and its cutting depth is limited. At present, the general high-feed milling cutter has a cutting depth of about 1.5mm, which is far lower than the conventional face milling cutter. 3mm or even 7~8mm can be achieved

The invention discloses a large-cutting-depth large-feeding indexable milling cutter which comprises a rotating cutter body and a plurality of indexable milling cutter blades, wherein a plurality of chip discharge grooves are distributed along the circumference of the rotating cutter body; a cutter blade positioning groove is formed inside each chip discharge groove; the indexable milling cutter blades are arranged inside the cutter blade positioning grooves; two circumferentially adjacent indexable milling cutter blades are arranged in a staggered manner; bottoms of two indexable milling cutter blades are connected with blade lengths of cutting blades. The large-cutting-depth large-feeding indexable milling cutter has the advantages that the structure is simple, the cutting efficiency is high, and the application range is wide.
Description
technical field [0001] The invention relates to a machining cutter, in particular to an indexable milling cutter with large depth of cut and large feed. Background technique [0002] In the international market, high-feed milling cutters have been widely used in the mold market and automotive industry and other machining industries. The biggest feature of this kind of cutter is that it can realize high-feed processing, thereby improving processing efficiency. The feed per tooth of the high-feed milling cutter can reach about 3mm at present, which can be increased by more than ten times compared with the traditional face milling cutter, but at the same time it is at the expense of the depth of cut, because the high-feed milling cutter The design principle is to set the cutting edge at the bottom of the blade and the bottom surface of the cutter head at a certain angle, and transform the radial force of the ordinary milling cutter into the axial force of the high-feed milling ...
