A cutting plate for a processing tool, particularly a milling tool, is connected to a holding device for such a cutting plate. The cutting plate has at least one blade () configured in a radially protruding manner on a central body () of the cutting plate. The central body () is provided with a coupling part for mounting the cutting plate on a frontal seat of a shaft-type holding device () which defines a longitudinal axis. The coupling part forms at least one driving surface transmitting an operating torque from the holding device () to the cutting plate. The cutting plate also includes a shaped part which forms a fixing device on the seat () of the holding device () in cooperation with an associated embodiment ().

Cutting plate for a processing tool and holding device for such a cutting plate

A holding device for machine tool inserts includes a recess delimited by clamping jaws. The recess serves as a clamping seat for the insert. The holding device also includes a slot extending the recess and having a receptacle for a spreading body of a spreader key. The slot has a half-circular expansion on one of its edges serving as a receptacle for the spreading body. The cross section of the spreading body of the spreader key is a polygon outline in the shape of an isosceles triangle whose corners are each rounded with an equal radius of curvature.

Holding device for machine tool inserts

A holder for free-cutting machining tool inserts, especially for chiseling, piercing or cutting inserts, includes an essentially beam-like edge support (1) with a receiving pocket (5) constructed in its end for the blade edge inserts. Clamping jaws (9 and 11) define the narrow width of the receiving pocket (5). A slot (29) is configured in the blade edge support (1) forming a flexible pivot for moving one clamping jaw. An operating member (37) is provided for producing a clamping force in the area of the slot (29) on the movable clamping jaw (11). The operating member (37) is mounted in a bore (39) at some distance from the slot (29). The clamping force is transmitted to the movable clamping jaw (11) through a force transmission member (43) which is slidably guided in the blade edge support (1).
