摘要： The milling cutter, in particular a round-head milling cutter, has a tool head, which extends along an axial direction and has a number of cutting teeth that each have a cutting edge. Chip flutes are located between each of the cutting teeth. The cutting teeth each have a front-side radial portion and a circumferential axial portion. The respective cutting edge and the chip flute are disposed such that they are inclined in opposite directions with respect to the axial direction such that the cutting tooth widens towards a foot region. In another embodiment, the tool head has two parts; a carrier part made of a tool steel, and a cutting part made of hard metal fastened to the carrier part. The milling cutter is distinguished by a long service life with a high cutting rate and a high quality of machining.

摘要： The present invention relates to a cutting insert for a cutting tool for the chip-removing high feed milling machining of workpieces, the cutting tool having a holder with a seat for receiving the cutting insert, the cutting insert having at least one cutting edge lying in a covering surface. To achieve a higher feed speed and greater cutting depth, particularly during high feed milling, there is provision, according to the invention, whereby the cutting edge has in portions three different radii of curvature, a first portion having the smallest radius, a middle second portion adjoining it having the largest radius, and a third portion adjoining the latter having a medium radius lying between the smallest and the largest radius, and whereby a peripheral line, running through all the cutting edges, of the covering surface is exclusively convexly curved. The invention relates, furthermore, to a correspondingly configured holder and to a cutting tool.

摘要： An indexable cutting insert includes at least two side edges each defining an indexable edge of the insert and at least two cutting teeth are on each indexable edge. The cutting insert includes locating means on a plane of the upper face and/or a plane of the lower face. When mounted on a material removal tool, the locating means cooperate with receivers on the working face of the material removal tool to constrain degrees of freedom of the cutting insert. Further, the mounted cutting inserts each locate the radial edge of the cutting teeth in the active position on a common circumference of a circle centered on an axis of rotation of the material removal tool. A mounting system per see is also disclosed as well as a method of removing material from a workpiece with the material removal tool.

摘要： A cutter includes a cutter handle and cutter head including a main body and a plurality of curved cutting edges separately extending from a periphery of the main body. Each cutting edge has a top surface, a first side blade surface, a second side blade surface, and a bottom surface. The top surface, the first side blade surface, the second side blade surface, and the bottom surface intersect to form a front edge, a middle edge, and a back edge. The front edge, the middle edge, and the back edge cooperatively form an edge tip. A tangent of the middle edge at the edge tip intersects with the bottom surface to form a cutting angle in a range from 30° to 60°.

摘要： 12. A rotationally drivable milling cutter has a cylindrical carrier body (10), which is equipped on its circumference with a plurality of cutting bodies (12) comprising a cutting material that is harder than hard metal. The cutting bodies (12) are embodied in platelike form and are each embodied and disposed such that the leading region of the radially outer circumferential edge forms the cutting edge, the adjacent side face (15) forms the first face with a negative rake angle, and the top face (17) diametrically opposite the bottom face forms the flank. To that end, the cutting bodies (12) are each secured with their bottom face on the end face of blind bores (30), in the circumferential face thereof, that are oriented with the angle to the shortest connecting line between the center point of the end face and the center longitudinal axis of the carrier body (10) such that the side face (15) adjacent to the cutting edge forms the predetermined rake angle.

摘要： In this insert, in addition to the insert being formed so that the cutting edge is twisted at a helix angle within the range of 5° to 25° about the axis when the insert is attached to the insert mounting seat, the thickness of the insert body at the flank located on a straight line, which passes through the center of the rough hemisphere formed by the rotational locus of the cutting edge and forms an angle of inclination of 90° relative to the axis, is set to be within the range of 0.5D to 0.9D relative to the thickness D of the rough plate that composes the insert body. As a result, since a comparatively gentle but adequately large helix angle is imparted to the cutting edge, cutting resistance decreases. In addition, since the thickness of the insert body at the flank on the rear end side of the insert body is not excessively thin, the rigidity of the insert body is adequately secured.

摘要翻译： 在该插入件中，除了插入件之外，当插入件附接到插入物安装座时，切削刃以围绕轴线的5°至25°的范围内的螺旋角度被扭转，插入件的厚度 在通过切削刃的旋转轨迹形成的粗糙半球的中心的直线上的侧面上形成相对于轴线形成90°的倾斜角度的主体被设定在 相对于构成插入体的粗板的厚度D为0.5D〜0.9D。 结果，由于赋予切削刃相当温和但足够大的螺旋角，所以切削阻力降低。 此外，由于插入体在插入体的后端侧的侧面的厚度不会过薄，因此能够充分确保插入体的刚性。
