    摘要： A throwaway insert for a ball end mill having an ideal cutting edge shape corresponding to the cutting speeds and loads at different portions of the cutting edges, high in strength and capable of discharging chips smoothly. As viewed in a direction perpendicular to the line connecting noses, each cutting edge forms a convex curve with its nose portion at the lowest level. As viewed in a direction perpendicular to the abovesaid direction, rake faces form symmetrical, downwardly sloping convex accurate surfaces or straight surfaces having a positive rake angle of 5-25.degree.. The wedge angle at the cutting edges is set at 85-65.degree.. Thus, the rake angle will be negative at the noses and positive at other portions. Further, the rake angle increases toward the side where the cutting speed is higher. The thickness of the insert increases toward the side where the load is greater. Since this insert is a modification of a negative insert, i.e. an insert of the type having a side perpendicular to its bottom, it has enough strength. Chips can be discharged smoothly too.

    摘要翻译： 一种用于球头铣刀的一次性刀片，其具有对应于切削刃的不同部分处的切削速度和负载的理想切削刃形状，强度高并能平滑地排出切屑。 从垂直于连接鼻部的线的方向观察，每个切割刃形成凸起曲线，其鼻部部分处于最低水平。 从与上述方向垂直的方向观察，前刀面形成对称的，向下倾斜的凸形精确表面或具有5-25°的正前角的直线表面。 切削刃处的楔角设定在85-65°。 因此，前角在鼻部为负，其他部分为正。 此外，前角朝向切割速度较高的一侧增加。 插入件的厚度朝向负载较大的一侧增加。 由于该插入件是负插入件的改型，即具有与其底部垂直的一侧的插入件，其具有足够的强度。 芯片也可顺利放电。

    摘要： A throwaway insert for a pin mirror cutter in which eight corners can be used and which the cutting performance and machining accuracy can be increased by making positive the axial rake angle of the peripheral cutting edge. Side faces of a negative insert of a parallelogrammic shape are formed by two surfaces connecting to each other at an angle so as to have a first included angle and a second included angle. Further, independent arcuate surfaces are provided at the intersections between the arcuate corner sides of each of the side faces and the top and bottom surfaces and the intersections between the obtuse corner sides and the top and bottom surfaces.

    摘要： The present invention provides a pin milling cutter formed by combining a cutter and an adapter to prevent errors in attaching a cutter to the adapter even when the cutter is similar but of a different type and even if the engagement section between the cutter and the adapter are the same. A mounting error prevention mechanism is provided on a main cutter unit and an adapter to prevent an erroneous combination of a cutter and adapter from fitting together normally. The mounting error prevention mechanism includes: a projection and a cavity corresponding to the main cutter unit and the adapter and providing a tapered fit; and a projection and a corresponding groove. The projection can be inserted into the groove only when the cutter and the adapter are combined correctly.

    摘要： A replaceable-blade cutting insert for corner milling cutters has a first and second surface; a third and fourth surface connected to a first side edge and a second side edge thereof respectively; and a fifth and sixth surface connected to a first edge and a second edge of the first surface and the second surface respectively. The first surface is used as rake face, the third surface is used as an outer perimeter flank face, and the fifth surface is used as a forward flank face. A twisted surface is disposed on a section of the third surface, forming a ridge line that acts as a main cutting edge intersecting with the first surface and interposed between the third and first surface. The first and second surface can be positioned with a height offset relative to each other so that at least one set of diagonal corners are projected.

    摘要： A disposable cutter has a cutter body formed with chip pockets and a plurality of disposable inserts having cutting edges. Each pocket is formed at least at the front or inner side of the body with a spherical blind groove portion. The center of radius of curvature of the spherical blind groove portion is located on an imaginary line drawn from the front end of each cutting edge toward the pocket at a substantially right angle with respect to each cutting edge.
