摘要： A throwaway ball end mill comprising an end mill body and a tip pressed by a clamp screw onto a cutout formed at the forward end of the end mill body. The cutout is formed in a longitudinal direction with respect to the end mill body, and a pair of lateral regions forked by the cutout have opposite flat surfaces, the lateral regions have clamp holes formed in a direction making a right angle with the cutout, one clamp hole has a conical surface extending toward the periphery of the corresponding lateral region, and the other clamp hole has a female thread formed therein,the centerline of the conical surface is deviated from that of the clamp holes toward the base end of the end mill body. When the clamp screw is tightened with the tip inserted in the cutout, the tip is pressed against the end of the cutout accordingly, and at the same time one lateral region is bent toward the other lateral region.

摘要： An insert rotary cutter for processing a metal workpiece includes a cutter body of a generally circular cross-section having an axis of rotation therethrough. The cutter includes one or more cutter inserts releasably mounted on a periphery of the cutter body. The insert includes a generally quadrilateral plate defined by a front face, a rear face disposed generally parallel to the front face and four side faces. The insert has a pair of main cutting edges defined by the front face and one pair of the opposite side faces. The pair of opposite side faces serve as respective rake surfaces for the main cutting edges. Each of the rake surfaces is convexly curved in such a manner that the width of the insert between the rake surfaces is larger at a central portion of each main cutting edge than at opposite ends of the main cutting edge.
摘要翻译：用于处理金属工件的插入式旋转切割器包括具有通过其旋转的轴线的大致圆形横截面的刀具本体。切割器包括可释放地安装在切割器主体的周边上的一个或多个切割器刀片。插入件包括由前表面限定的大致四边形板，大体上平行于前表面设置的后表面和四个侧面。刀片具有由前表面和一对相对侧面限定的一对主切削刃。一对相对的侧面用作主切削刃的相应的前刀面。每个前刀面以这样的方式凸出地弯曲，使得前刀面之间的刀片的宽度在每个主切削刃的中心部分比在主切削刃的相对端处更大。
