20190084056 · 2019-03-21 ·

An axially and radially compliant deburring tool holds a commercially available end tool holder, which in turn holds a variety of commercially available interchangeable deburring end tools, such as those commercially available for the hand deburring market. The axially and radially compliant deburring tool exhibits axial compliance in response to an external force by allowing a longitudinal sleeve holding the end tool holder to move longitudinally along a longitudinal axis of the tool, against a bias force. The axially and radially compliant deburring tool exhibits radial compliance in response to an external force by interaction between a cam contact member and a concave cam surface, both under the bias force and hence operative to return the commercially available to a centered, extended position in the absence of external forces.
