Milling tool for producing a countersink, machine for turning and advantages of a countersink

摘要

The present invention relates to a milling tool (100) comprising a stem (110) is axially symmetrical about a longitudinal axis (a) intended to coincide with the axis of rotation (x) of a machine for turning (20) and a cutting head (130) connected to the shank by a rod (120). The rod (120) extends along a direction (b), parallel and offset relative to the longitudinal axis (a) of the tail (110) of the milling tool, and in that the cutting head (130) projects from the rod (120) in a direction perpendicular to the direction (b) along which extends said rod, the cutting head (130) comprising a cutting edge (132) forming an angle less than or equal to 90° with the longitudinal axis (a) of the tail (110) of the milling tool. The present invention also relates to a machine equipped with such a vertical lathe tool, and a method of producing a countersink.
