Problems solved by technology

[0002] Grooves need to be machined on the mobile phone shell. In the past, the milling cutter was placed horizontally, and the blade was set on the side of the cutter bar, and then extended into the mobile phone shell to process irregularly shaped grooves. The above-mentioned processing method is difficult to process, so the applicant designed A one-piece forming knife can process the three sides of the groove in a vertical manner, thereby reducing the difficulty of processing

Abstract

The invention discloses a cutter capable of integrally forming a groove, which is characterized by comprising a cutter bar, a cutter neck and a cutterhead which are sequentially arranged, wherein a plurality of edge parts integrally formed with the cutterhead are annularly and uniformly arranged on the side surface of the cutterhead; each edge part comprises an arc-shaped rake face, a left first flank face, a bottom first flank face, a right first flank face, a left second flank face, a bottom second flank face and a right second flank face, wherein the rake face intersects with the left firstflank face to form a left cutting edge, the rake face and the bottom first flank face intersect to form a bottom cutting edge, the rake face and the right first flank face intersect to form a right cutting edge, and the left cutting edge, the bottom cutting edge and the right cutting edge continuously intersect; the rake faces and the side surface of the cutterhead define a chip discharge groove;and the left cutting edges and the bottom cutting edges are arc-shaped, the right cutting edges are straight, and the left cutting edges, the bottom cutting edges and the right cutting edges are smoothly connected.

Description

technical field [0001] The invention relates to a milling cutter, in particular to a groove integrally formed cutter. Background technique [0002] Grooves need to be machined on the mobile phone shell. In the past, the milling cutter was placed horizontally, and the blade was set on the side of the cutter bar, and then extended into the mobile phone shell to process irregularly shaped grooves. The above-mentioned processing method is difficult to process, so the applicant designed A one-piece forming knife can process the three sides of the groove by vertical processing, thereby reducing the difficulty of processing. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a groove-integrated knife. [0004] The technical solution adopted by the present invention to solve its technical problems is: [0005] A groove integrally formed knife is characterized in that: it includes a knife rod, a knife neck, an...
