Hard chuck jaw

Overview
We provide a full range of heat treatment services including through-hardening, induction hardening, carburizing, vacuum quenching and related processes. We also perform various grinding and polishing operations such as surface grinding, cylindrical grinding, barrel polishing and buffing. Integrated process management and delivery for multi-operation parts including machining are available.
