Abstract: An indexable cut-off saw is used for cutting metal components, e.g. cutting a bearing cap cluster into separate caps. The saw has a circular tool body for mounting on an arbour and this tool body has flat side faces and a narrow outer periphery. A plurality of circumferentially equally spaced cutting inserts are mounted at the outer periphery of the tool body, these inserts being arranged in groups of three such that the total width of the saw cut is divided between the actions of three cooperating cutting inserts. These three cooperating cutting inserts include a central insert mounted centrally on the outer periphery of the tool body and left and right side inserts mounted in pockets extending into the side faces of the tool body. The left and right side inserts are of rectangular configuration presenting straight cutting edges, while the central cutting insert of each group presents a curving cutting face. The central cutting insert is preferably in the form of a cylindrical cutter disc with flat end faces providing a cutting edge disposed about the periphery of an end face. These cylindrical cutter discs are mounted on an end face thereof at an angle within about 1.degree.-15.degree. of coincidence with the direction of travel of the insert during cutting. It is also possible to use as the central cutting insert a circular cutting disc mounted axially into a pocket in the periphery of the tool body.

Abstract translation: 可转位切割锯用于切割金属部件，例如， 将轴承盖簇切成单独的盖。 锯具有用于安装在心轴上的圆形工具体，该工具主体具有平坦的侧面和窄的外周。 多个周向相等间隔的切削刀片安装在工具主体的外周，这些刀片以三个组合布置，使得锯切的总宽度在三个协作的切削刀片的作用之间分开。 这三个配合的切削刀片包括安装在工具主体的外周上的中心插入件，以及安装在延伸到工具主体的侧面的凹穴中的左侧和右侧插入件。 左侧和右侧插入件具有呈现直的切割边缘的矩形构造，而每组的中心切削刀片呈现弯曲切割面。 中央切削刀片优选为圆柱形切割刀片的形式，其具有平坦端面，其提供围绕端面周边设置的切割边缘。 这些圆柱形切割盘在切割期间以与插入件的行进方向一致的约1°-15°的角度安装在其端面上。 还可以将中心切削刀片用作轴向安装在工具主体周边的凹槽内的圆形切割盘。

Abstract: A broaching tool is described having an elongated tool body with a plurality of spaced ribs disposed generally transverse to the longitudinal body axis. Each such rib defines a substantially circular arc of at least 45.degree.. A plurality of cylindrical cutter discs are mounted along each rib, each disc being positioned with its longitudinal axis disposed within 1.degree.-15.degree. of coincidence with the longitudinal axis of the body. Each disc has an end face providing a cutting edge disposed about the periphery of the end face. The discs along each arcuate row are circumferentially staggered with respect to the discs of the next adjacent rib with each disc projecting beyond the outer face of the rib and being rotatably indexable about its axis to bring successive cutting portions into cutting positions.
