Cutting tool having an adjustment mechanism

摘要

A cutting tool has a tool body provided with at least one insert pocket in which a cutting insert is retained. A device for adjusting a position of the cutting insert within the insert pocket is also provided. A cavity adjacent the insert pocket accommodates an adjustment wedge having a forward surface in sliding contact with a minor side surface of the cutting insert and an adjustment screw threadingly engaged with a female threaded section of the adjustment wedge. The adjustment screw is constrained to remain in its position in the cavity, although rotation of the adjustment screw about its axis results in a sliding motion of the adjustment wedge relative to the cavity and a sliding motion of the forward surface relative to the minor side surface, which translates to displacement of the cutting insert in a direction parallel to a base surface of the insert pocket.
