A deburring tool for stable processing is provided. The deburring tool includes a cylindrical housing; a spindle loosely fitted and supported to be tiltable with respect to an axis of the housing, the spindle having a rotatable attachment portion for detachably attaching a cutting tool at a distal end; a pressed member arranged to the spindle; a piston slidably disposed inside the housing, the piston configured to press the pressed member toward the distal end; an elastic member configured to urge the piston toward the distal end; a separate ring arranged between the piston and the elastic member; and a flow path for supplying a compressible fluid between the separate ring and the piston.

A flexible bit holder may include a drive body having a receiving orifice formed therein, a drive body having a shank and a flexion assembly. The receiving orifice may be configured to receive a bit, and the shank may be configured to interface with a driver to receive rotational energy from the driver. The flexion assembly may be disposed between at least a portion of the drive body and the driven body to operably couple the drive body and driven body. The flexion assembly may be configured to transfer torque applied to the driven body by the driver to the drive body. The flexion assembly may be formed of flexible material such that the drive body is rotatable relative to the driven body about a common axis of the drive body and the driven body.

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.

A tool holder includes a tubular body having a shank on a first axial end portion, a tool gripping portion on a second axial end portion, and an elastic segment interposed between the shank and the tool gripping portion in the axial direction of the body. The elastic segment is more elastically deformable along the axial direction and around a circumferential direction of the tubular body than the shank and the tool gripping portion owing to a plurality of voids that extend through the elastic segment from an outer peripheral side of the tubular body to an inner peripheral side of the tubular body. Each of the voids includes segments that extend around the circumferential direction and along the axial direction of the tubular body.

A flexible coupling for attaching a collet to a draw bar includes a draw bar having a first longitudinal axis and a first coupling portion. The first coupling portion includes two or more legs spaced apart from one another with each of the legs having first coupling surface formed thereon. The flexible coupling includes a collet having a second longitudinal axis and a clamping portion proximate one end of the collet. The collet includes a second coupling portion proximate a second end of the collet. The second coupling portion has a second coupling surface formed thereon and configured in a shape complementary to the first coupling surface so that the first coupling surfaces moveably engage the second coupling surface such that the first longitudinal axis and the second longitudinal axis are coaxial when an axial force is applied to the draw bar and the collet.

A chuck device that allows easy attachment of a clamping target component and can provide powerful and highly reliable clamping includes a main body including a metal core part and an annular space coaxial with and formed around the metal core part; a rubber elastic body fitted in the annular space of the main body such that there is a pressure chamber between a circumferential wall that defines the annular space and the rubber elastic body, and a clearance for allowing a tubular clamping target component to be inserted between the rubber elastic body and the metal core part; and a passage for introducing a fluid to the pressure chamber, wherein the rubber elastic body is deformed to expand toward the metal core part by a pressure of a fluid introduced to the pressure chamber via the passage so that a tubular clamping target component that is attached to the metal core part is clamped by the metal core part and the rubber elastic body that has deformed to expand.
