摘要: A parting tool includes a thin holder forming a groove open at one end, and a double-ended cutting insert mounted in the groove. The insert includes front and rear cutting edges and a rear end surface abutting against a rear support surface of the groove. The rear support surface is configured to enable differently shaped double-ended inserts to be mounted therein without the occurrence of contact between the rear cutting edge and a surface of the holder.

摘要: A cutting insert for grooving operations includes a central shank portion and a forward cutting head. The cutting head includes a front clearance surface having a main cutting edge at an upper end thereof. The clearance surface is non-planar. Rather, the clearance surface exhibits a curvature in order to strengthen the main cutting edge.

摘要: A double ended metal-cutting insert includes a pair of circular cutting edges disposed at respective end surfaces of the insert. Each end surface includes an upper portion connected to the cutting edge, and a lower portion connected to the upper portion by a concave transition portion. The lower portion is recessed relative to the upper portion in a direction toward the opposite cutting edge. The lower portion is a flat face oriented perpendicular to the bottom surface.

摘要: A tool for chip-removing machining includes an insert holder and an insert that is mechanically connected with the holder via upper and lower interfaces. Each interface includes a pair of contact surfaces that extend at an obtuse angle relative to each other. Disposed centrally between one of those pairs of contact surfaces is a ridge, and disposed centrally between the other pair of contact surfaces there is a flute. Each of the recess and flute is defined by side surfaces that extend at an acute angle relative to each other. When the ridge engages the flute, a proper absorption of transverse forces acting upon the insert is guaranteed, whereby the insert is maintained essentially immovable in its position in order to guarantee a proper machining accuracy.

摘要: A tool for chip removing machining includes a holder and a cutting insert removably mounted therein. The insert includes a shaft having opposite ends and defining a first longitudinal center line. A cutting head projects integrally from at least one end of the shaft. The cutting head includes a cutting edge forming an angle of 45° with the first longitudinal center line. Alternatively, or additionally, the cutting head defines a second longitudinal center line forming an angle of 45° with the first longitudinal center line.
