Materials Testing Product Information Specimen blanking machines for specimen preparation of metals Hydraulic specimen blanking machine type M-Cut 65 Hydraulic specimen blanking machine type RZ 100 Nowadays test pieces from steel sheet and metal foils are economically and accurately produced using speci- men Planking machines. The standards, e.g. ISO 6892, ASTM A 370, ... stipulate that the test results must not Pe influenced by any material change caused by strain-hardening at the test piece edge zone. Numerous structural examinations of steel sheet have shown that the strain-hardening zone along the cut- ting line is generally a maximum 10 % of test piece thickness. This is achieved by a low cutting speed and special blanking tool design and offers substantial eco- nomic advantages in the event of subsequent grinding. In this way high specimen quality is ensured. We offer following models: C-shape specimen blanking machines The open shape of specimen blanking machines and blanking tools (C-shape) also allows specimens to be taken from panels. If several blanking tools are used the roller table version of the table extension is recom- mended: So blanking tools not being used at that time can be put aside. With table extension, tool changes take about 20 seconds, offering significant time-savings where tool changes are frequent. The blanking machine M-Cut 65 (with a compressive force of 650 kN) is suitable for the material thicknesses 0.04 to 6 mm (depending on tensile strength and speci- O-shape specimen blanking machines The closed shape (O-shape) requires pre-cut strips 70 ... 80 mm wide. These specimen blanking machines are already equipped with a table extension. Blanking tools Blanking tools can be produced exactly to customers' requirements, an example being tools made from a spe- cial steel which were produced with additional guides to enable dumbbell specimens to be punched from foils with a thickness of 0.04 mm and a tensile strength of 2,150 MPa. Depending on the strength of the material, duced with the tools, which can then be re-sharpened. • Fast, cost-efficient production of tensile specimens • No specialists required - anyone can operate the machine after a brief training period • Manufacture of very high-quality specimens by finishing with a specimen grinding machine • Robust, easily maintained machines • Long edge life of the blanking tools and possibility of repeated resharpening
