Abstract: An electrically powered disc cutting machine for cutting off discs from in particular elongate material to be cut, preferably food, includes: a cutting device having a circular blade that rotates in a cutting plane about an axis of rotation perpendicular to the cutting plane and is driven by a blade motor. The cutting device includes: a carriage for carrying a carriage plate in a carriage plane perpendicular to the cutting plane and to carry at least one carriage wall that protrudes from the carriage plane; and a holder for material to be cut, the holder having a bearing surface for receiving the material to be cut and for bringing the material to be cut closer to the circular blade at an angle ?<90° relative to the cutting plane. The holder for material to be cut includes a fastening apparatus for fastening the holder for material to be cut.

Abstract: The invention relates to a cold-rolled flat steel product which, despite high strength values, has a high level of deformability characterized by a high elongation at break and a good hole expansion ratio ?M. For this purpose the flat steel product is produced from a steel that is composed of (in % by weight) C: 0.12-0.19%, Mn: 1.5-2.5%, Si: >0.60-1.0%, Al: ?0.1%, Cr: 0.2-0.6%, Ti: 0.05-0.15% with the remainder being iron and unavoidable impurities caused by the production process, and which comprises a perlite- and bainite-free structure having 4-20% by vol. martensite, 2-15% by vol. residual austenite, remainder ferrite, an elongation at break A80 of at least 15%, a tensile strength Rm of at least 880 MPa, a yield strength ReL of at least 550 MPa and a hole expansion ratio ?M of more than 6%. The invention also relates to a method which easily enables production of a flat steel product according to the invention.
