  • Patent number: 10835967
    Abstract: A hole cutter has a substantially cylindrical blade body defining a blade body circumference, a cutting edge formed on one end of the blade body, and an axially-elongated slot formed through the substantially cylindrical blade body. The axially-elongated slot is configured to receive chips flowing from the cutting edge within the interior of the blade body and (i) into the slot and/or (ii) through the slot, to prevent the collection of such chips within the interior of the blade body and/or at an interface between the blade body and the work piece. The axially-elongated slot defines a first end adjacent to the cutting edge, a second end axially spaced further from the cutting edge, and a slot area. The hole cutter further defines a total slot area to blade body circumference ratio within the range of about 0.1 to about 0.3 depending on the size of the hole cutter.

  • Patent number: 10814407
    Abstract: 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.

  • Patent number: 10766110
    Abstract: A tool changer includes a holding member having a tool change arm disposed thereon, a rotation mechanism rotating the holding member at a first rotation speed in normal and reverse directions, a forward/backward movement mechanism moving the holding member forward and backward at a first forward/backward movement speed, and a controller comparing a first difference as a difference between a command value for the rotation and an output value of an encoder with a first threshold. When the first difference is equal to or greater than the first threshold, a rotational speed of the holding member is chained to a second rotation speed slower than the first rotation speed. Alternatively, when the first difference is less than the first threshold, the rotational speed of the holding member is maintained at the first rotation speed.
