Abstract (en)
[origin: EP2722194A1] The tool (11) has upper tools (21) for receiving machining tools (20), and a secondary tool (22) for receiving a backstop. The backstop is operated as a spring ball. The upper tools and the secondary tool are arranged opposite to each other such that a workpiece (12) is arranged between a side of the backstop and sides of the machining tools. The spring ball comprises an outer rim, which comprises smaller surface hardness than the workpiece to be machined on a workpiece surface of the workpiece to be machined. The outer rim is designed as a coating or a covering.
