A processing apparatus includes a rotary table that causes a workpiece to rotate around a rotary axis, a roller-shaped member that rotates on an axis orthogonal to the rotary axis of the rotary table, a vertical driving section that is driven in a direction of the rotary axis of the rotary table so as to bring the roller-shaped member and the workpiece into contact with each other, an ultraviolet ray irradiation source that irradiates a portion between the roller-shaped member and the workpiece with an ultraviolet ray, a polishing material that is supplied to the portion between the roller-shaped member and the workpiece, and a light scattering medium that is supplied to the portion between the roller-shaped member and the workpiece and scatters an ultraviolet ray from the ultraviolet ray irradiation source.

A size-adjustable adaptive online wheel deburring device, including a synchronous clamping and rotating system, a left brush system, and a right brush system. The synchronous clamping and rotating system enables the wheel to rotate in a clamped state; the servo electric cylinders and a servo motor adjust the left working wheel, the left adjusting wheel, the right adjusting wheel and the other left working wheel to respective corresponding positions, and adapt the shape of a belt-type brush to a back cavity shape and the radius of the wheel; other servo electric cylinders can adjust the positions of the right working wheel and right working wheel according to the back cavity shape and the size of the wheel, another servo electric cylinder can remove the burrs on the flange root corners and rim root corners of the wheel by adjusting the angle of the right brush system.
