The device for supporting a cutting-tool is intended to be placed in a head for machining grooves in a cylindrical rod and mainly comprises a frusto-conical support member having an axial bore through which the cylindrical rod to be machined is capable of passing. The support member is placed within a frusto-conical recess of the machining head and provided with a cutting-tool recess having an opening which defines the profile of the cylindrical rod. The cutting-tool is clamped within its recess by means of a ring which is screwed into the support member and has a control front face for receiving the rod to be machined.

Tool-supporting device for machining a cylindrical rod and a machining

A machining tool comprises an annular structure having the same number of teeth as there are grooves to be machined, arranged radially in the structure, each tooth carrying a pin engaged in a curved slot. It also comprises a locking device constituted by a ring occupying a recess in the structure and a system of pawls carrying fingers which penetrate into the curved slots of the structure. It also incorporates a collar for controlling the locking device.
