New description: [New technical field] This creation is about the improvement of the spherical structure of the round head, especially the sharp knife structure of the spiral blade of the ore cutter blade. To make the knife and life and sharpness last longer. [Prior Art] As for the "sharp knife of the round head", it is applied to the sharp car bed, and the curved surface is cut into the curved surface, which is made by the missing cylinder seat. Or the cutting of the curved surface, and the dragon's milling cutter 1 Q structure (as shown by the first circle) is mainly composed of a plurality of spiral blade portions 1 2 screwed to the front end of the rod body 1 1 and two (10) spiral blade portions 丄2 sets of a row of chips 3' (such as the first - map Ma), but the listening structure encountered in the work of the material to see _ questions such as: 1. Because the blade i 2 is spirally wound around the body 2 i The chips generated on the workpiece are elongated, and the high-speed rotation of T, f makes the long-shaped field difficult to be discharged by the chip-scraper 3, which causes the process to be secreted and reinforced.丨2 is used by a husband. .接触 兴 兴 加工 的 的 兴 兴 兴 兴 兴 兴 兴 兴 兴 兴 兴 兴 兴 兴 兴 兴 兴 兴 兴 兴 兴 兴 兴 兴 兴 兴 兴 兴 兴 兴 兴 兴 兴 兴Take the vibrating test line of Shengwang* ’ discovery _ lost, _ kind of question. - Out of the case, with Dalin and effective transfer of the practice type [new content] M375568 ^ The main purpose of the creation is to reduce the resistance, solve the problem and reduce the vibration during processing. And maintain the sharpness of its cutters to achieve sharp cutters that are more suitable for curved surfaces. [Embodiment] In order to enable your review committee to further understand the content and efficacy of this creation, please refer to the detailed description of the following:
請參閱第二圖至第三圖所示者， 旋刀刃部2 2旋設於桿體21前端， 排屑槽2 3，其特徵在於： 本創作主要係由二個或二個以上之螺 而兩相鄰的螺旋刀刃部2 2間設有一 八每-職刀刀部2 2的外圍於預定角度、間距凸伸複數個齒刃2 4， 以々_旋刀刀2 2部形成螺旋鑛齒刀刀狀者（如第三圖所矛者广 二，構者，當進行高速旋轉對加工物進行切削動時，由螺旋刀刃部 、刀4同時對加工物進行切屑，而令切屑形成短 而可改善習積屑問題。 ⑷狀排出 丹者 觸面_&、刀刃部22係由複數個齒刀24構成，與加工物的接Referring to the second to third figures, the rotary blade portion 2 2 is screwed to the front end of the rod body 21, and the chip flute 2 3 is characterized in that: the creation is mainly composed of two or more screws. Between the two adjacent spiral blade portions 22, a periphery of the eight-per-knife blade portion 2 2 is protruded at a predetermined angle and a plurality of tooth edges 2 4 at a predetermined angle, and the spiral ore is formed by the 々-rotary knife 2 If the cutter is in the shape of a knife, as in the case of the third figure, when the workpiece is cut at a high speed, the workpiece is scraped by the spiral blade and the knife 4, and the chip formation is short. It can improve the problem of the accumulation of chips. (4) The shape of the contact person is _& The blade portion 22 is composed of a plurality of tooth cutters 24, and is connected with the workpiece.
