A tool includes a flexible section; a head that extends form the flexible section; and an exciter within the head. A method of additively manufacturing a component including burrowing a tool into a conglomerated powder within an internal passage of an additively manufactured component, the tool vibrating in a manner to facilitate removal of the conglomerated powder.

Disclosed is a device for automatically removing burrs from a riser of an aluminum alloy wheel. The device is composed of a frame, a clamping gear rack structure, a support plate, a servo motor and the like. When a clamping cylinder drives a left sliding plate to move, clamping wheels are controlled to center and clamp the wheel, and the servo motor controls the rotation of the clamping wheels, so that the wheel may rotate while being clamped. When a distance adjusting cylinder drives a right sliding block to move, a left sliding block and the right sliding block move synchronously under the action of a feed gear rack structure, so that a left burr tool and a right burr tool move synchronously to adjust the distance between them according to the diameter of a cap slot.

The application discloses a multi-station wheel burr removing device, includes lifting translation systems, a clamping drive system and grinding systems. In practical use, the four V-shaped rollers clamp a wheel, a sixth servo motor and the first electric servo cylinder respectively adjusts the angle and the position of the rolling brush, and when the rolling brush contacts the edge of a wheel flange, burrs can be removed; the fifth servo motor and the sixth servo motor respectively adjusts the position and the angle of the lower grinding head, and when the lower grinding head contacts a wheel valve hole, burrs below can be removed; the third servo motor and the second electric servo cylinder respectively adjusts the angle and the position of the upper grinding head, when the upper grinding head contacts the wheel valve hole, burrs can be removed.

A diameter expansion drill bit used to expand the diameter of a part of a prepared hole bored in a frame by grinding includes: a cutting-blade portion that has a plurality of separate cutting-blade portions; a cutting-blade holding portion that slidably holds the plurality of separate cutting-blade portions in a radial direction; and a shank portion that supports the cutting-blade holding portion. The plurality of separate cutting-blade portions is arranged in a peripheral direction and arranged over a plurality of stages in a shaft direction, and the plurality of separate cutting-blade portions of the respective stages is caused to slide by a centrifugal force resulting from rotation so as to spread to an outside in the radial direction with respect to the cutting-blade holding portion.

A honing tool for working several separate bores that are arranged coaxially in series and have different diameters. The honing tool includes several cutting bar groups arranged coaxially in series, wherein a diameter of a cutting bar group of the several cutting bar groups, which diameter is formed by radially extendable cutting bars, differs from a corresponding diameter of at least one other cutting bar group of the several cutting bar groups. A centering bar group is arranged in an axial direction to a free end of the honing tool adjacent at least one cutting bar group; or a guide bar group is arranged directly adjacent opposite the free end of the honing tool adjacent the at least one cutting bar group, or both the centering bar group and the guide bar group are arranged accordingly.
