A device for removing flashes of a wheel blank includes two layers of turnover mechanisms, wherein the lower-layer turnover mechanism realizes the initial positioning of a wheel and has the function of removing the flashes at both the inner side and the outer side of an inner rim of the wheel, and the upper-layer turnover mechanism realizes the secondary positioning of the wheel and has the function of removing the flashes on the outer rim side. By means of the two layers of turnover mechanisms, the flashes on the front face and end face of a wheel blank outer rim wheel lip, and the inner side and outer side of the inner rim are removed, and coaxial processing conversion and orderly takt connection are ensured. The disclosure also provides a method for removing flashes of a wheel blank.

A perforating apparatus for a cylindrical workpiece, including: a cradle having a groove extending in one direction horizontally from one end to another end; a stopper provided at the one end of the groove; a drill disposed vertically above the groove and movable at least in vertical direction, having a drill bit that extends vertically; and a chuck having a pair of opposing grippers movable toward each other in a horizontal direction perpendicular to the direction in which the groove extends, and symmetrically with respect to a rotation axis of the drill bit, each of the grippers further having a pair of vertically symmetric inclined surfaces expanding upwards and downwards.

An orbital drill bushing adapter for use with a drill unit. In one embodiment, the orbital drill bushing adapter comprises a main body and locking arms. The main body includes a base member having an upper surface, a lower surface, and an external side wall that extends between the upper surface and the lower surface. The main body further includes a cylindrical spacer that projects from the lower surface of the base member, and is configured to fit in a drill hole of an orbital drill bushing. The main body includes a cylindrical hole that passes through the base member and the cylindrical spacer. The locking arms are pivotally coupled to the base member, and are configured to clamp the main body onto the orbital drill bushing.

An orbital drill includes a drilling portion, a shank portion, and a neck portion between the drilling portion and the shank portion. The drilling portion includes one or more right-handed spiral flutes with cutting edges having a positive axial rake angle for positive cutting action while orbiting into a material. The right-handed spiral flutes have a positive radial and axial rake angle. The drilling portion also includes one or more left-handed spiral flutes located rearward of the one or more right-handed spiral flutes with cutting edges having a positive axial and radial rake angle for positive cutting action while orbiting back out of the material and removing any material left in the hole, thereby eliminating a separate reaming operation. A method of machining a workpiece using the orbital drill is also disclosed.

A method for forming dimples on a workpiece includes providing a rotary cutting tool. The rotary cutting tool includes a cutting edge that protrudes in a leading direction parallel to a longitudinal axis of the tool. The cutting edge extends from a position at the leading end of the rod-shaped main body that is radially offset from the longitudinal axis. The rotary cutting tool is set such that the longitudinal axis of the rotary cutting tool is inclined relative to a line perpendicular to the processing surface of the workpiece. The rotary cutting tool is moved along the processing surface while the rotary cutting tool is rotated about the axis. The processing surface is cut by the cutting edge to form the dimples, which are spaced apart from each other on the processing surface.
