Machine tool drive system
A drive system for a machine tool comprises two, at least equally long drive spindles, extending parallel to each other and being structurally identical with regard to their torsional rigidity and their axial rigidity, which are each supported to rotate about a spindle axis, and which can be driven about the spindle axis concerned. Each of the drive spindles has a fixed bearing at one end, acting in its longitudinal direction. Spindle nuts, which are seated on the drive spindles can be moved simultaneously with longitudinal movements in the longitudinal direction of the drive spindles.

Bus bar and method for producing same
A bus bar formed using a metal plate is provided. The metal plate includes one or more holes extending through the metal plate on a bend line. The bus bar includes a folded part formed by bending the metal plate along the bend line through hemming. The folded part includes a first region and a second region. The first region is located between an outer edge of the metal plate and the bend line. The second region overlaps in close contact with the first region. The bus bar also includes a terminal arranged in the first region. The folded part includes one or more welds in which the first region and the second region are welded to each other.
Container and method for producing a container
The present disclosure relates to a mesh container and a method of making a mesh container that has a first and a second set of opposing side panels, a bottom panel, and a rim directed outwards from the upper edges of the side panels. At least two adjacent sides panels of the container and portion of the rim directed outwardly from the upper edge of the side panels are made from a sheet metal precursor with least one perforated and a stretched portion and unstretched metal portion. The precursor is folded so that the unstretched metal portion joins the two side panels and is bent to form the rim. A notch is cut from the edge of the unstretched metal portion where it is bent at the corner formed by the two side panels.
