Abstract

PURPOSE:To improve cutting efficiency by staggeredly fitting right and left side cutting edges to a body in a staggered teeth equal angle cutter for chipping the back side of an aluminum weld part. CONSTITUTION:Cutting edges are divided into left side cutting edges 1 and right side cutting edges 2 and staggeredly fitted to a body. When cutting is carried out by the use of this tool, first, the left half of a weld part is cut by means of the cutting edge 1 allowing a chip to escape in a direction 8 perpendicular to the cutting edge 1 and discharging it from the inside of the cutting edge. Then, the right side cutting edge 2 equally cut the right half, discharging a chip in a direction 9. Thereby, mutual interference between chips can be prevented, a built-up edge is not created, and the cutting efficiency can be improved.

のである。DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a staggered blade conformal milling cutter, and is particularly suitable as a tool for chiseling the back side of aluminum welds.

〔発明の背景〕[Background of the invention]

た。When cutting with a conventional conformal milling cutter, cutting waste flows along the rake angle, but since it flows from the left and right sides of the cutting edge toward the center, the cutting waste interferes with each other at the center of the cutting edge, resulting in a short period of time. Over time, a so-called built-up edge was generated, which had the disadvantage of being inefficient in terms of sharpness and shortened tool life.

〔発明の目的〕[Purpose of the invention]

したことを特徴とする。A built-up edge occurs because cutting chips cannot flow out smoothly from within the cutting edge. Therefore, in order to make the flow of cutting waste smooth, it is sufficient to prevent the cutting waste generated by the left and right cutting blades from interfering with each other. The present invention is characterized in that the cutting edges are arranged in a staggered manner and a rake angle is provided with respect to the cutting surface, so that the flow of cutting waste is made smooth.

切削を行うことができる。In the present invention, as shown in FIG. 1.2, the cutting blades are attached to the main body 10 in a staggered manner into a left cutting blade and a right cutting blade 2. In cutting, as shown in FIG. 6, in the first step, the left half of the welded portion 5 is cut with the dovetail cutting edge 1, and the cutting waste flows in the direction of arrow 8 and flows out from within the cutting edge. Next, in the second step, the right half is cut by the cutting blade 2 as shown in FIG. 7, and the cutting waste flows in the direction of the arrow 9. Therefore, there is no interference between the cutting chips and no built-up edge is generated. Furthermore, by providing the rake angle 4 shown in FIG. 4 in a direction perpendicular to the cutting surface, even sharper cutting can be performed.
