This system machines metallic tensile and Charpy/Izod impact specimens across the full range commonly encountered in QA and R&D laboratories, from soft and ductile alloys through hardened steels. With appropriate tooling and parameters, it can machine materials with hardness values exceeding 60 HRC.

Typical materials include aluminum and copper alloys, stainless and low-alloy steels, and tool or tool-hardened steels. The system supports standardized tensile specimen geometries such as ASTM E8/E8M and equivalent international formats, based on the selected fixturing.

In terms of part size, the Classic Upgrade accommodates specimens up to approximately 14 in (350 mm) long and 2 in (50 mm) wide, and it can machine single-piece stock up to 1.5 in (38 mm) thick. Fixturing options and the available machining envelope determine how parts are oriented and whether multiple specimens are run in one setup.

For impact testing, the system prepares standard Charpy/Izod impact blanks (for example 10 × 10 × 55 mm and 7.5 × 10 × 55 mm) with surface finishes suitable for reliable impact results. Final U- or V-notch preparation is typically performed using a dedicated impact notching or broaching machine in accordance with ASTM E23 and related standards.

If you need confirmation for a specific alloy, a high-hardness heat-treated material, thicker stock, or a higher-throughput workflow, learn more or request a quote and our applications team will review your material and specimen requirements.
