A rotation joint includes a base and a rotation member sleeved on the base. An end of the base defines at least one first air guiding hole and a first air outlet. An outer sidewall of the base defines an air guiding groove. The air guiding groove extends around an axis of the base. A bottom wall of the air guiding groove defines a second air guiding hole communicating with the first air guiding hole. The outer sidewall of the base further defines a second air outlet. The first air outlet communicates with the second air outlet. Sidewalls of the rotation member define connecting holes. One of the connecting holes communicates with the second air outlet, while the other connecting holes communicate with the air guiding groove. The present disclosure further provides a multiple air channel workstation using the rotation joint.

An exemplary metal structure () includes a base portion (), a flange (), and an edge portion (). The base portion defines a circular flanged hole (). The flange extends from a top surface of the base portion and the flange surrounds the circular flanged hole. The edge portion is configured for connecting an inside surface of the flange and the top surface of the base portion. The edge portion includes an edge surface, and a ratio of a radius of the edge surface () of the edge portion with respect to a thickness of the base portion is less than 0.4. A method for making a circular flanged hole in a metal sheet () is also provided.

An exemplary flipping apparatus includes a slider, a flipping member and a holding table. The slider is slanted relative to the horizon. A first end of the flipping member is connected to the slider. The flipping member includes a first flipping plate and a second flipping plate facing the first flipping plate. The first flipping plate and the second flipping plate are contoured to define a workplace groove to receive a workpiece to be flipped. An angle defined by the slider and an end section of the first flipping plate opposite to the slider is less than an angle between the slider and the horizon. The holding table is connected to a second end of the flipping member, and the second end is opposite to that of the first end of the flipping member.
