  • Industry-Specific Tools and Strategies for Machining

    Machining ISO-S materials is challenging because alloys transfer heat poorly, also known as low thermal conductivity. The heat generated in machining (~1100 degrees Celsius to 1300 degrees Celsius) is absorbed by the tool and workpiece instead of being carried away in the cut chips. Thereby, tool life suffers, and part distortion can occur.
