Grooving and turning tool with clamping surfaces

摘要

Small size insert and insert-blank apparatus for machine tools for grooving and turning have a body with generally parallel and opposing sides, and top and bottom surfaces which have at least a portion thereof inclined from adjacent a first end to the opposite end. The body of the apparatus is adapted to be mounted in a toolholder having a nest or pocket having an inclined bottom wall which cooperates with the inclined portion of the bottom surface of the apparatus, and a clamp secured to the toolholder having a finger portion cooperative with the inclined portion of the top surface of the apparatus to resist forces on the apparatus during turning. Small size insert and insert-blank apparatus optionally have at least one head having a rear end and a body extending from the rear end of the head having top and bottom surfaces with inclined portions intersecting the rear end of the head forming portions adapted to serve as stops to prevent rearward movement with respect to the machine tool when in use. The small size insert and insert-blank apparatus may include two heads extending from opposite ends of the body, each head having a rear end with which the body forms portions adapted to serve as stops to prevent rearward movement with respect to the machine tool when in use.
