Tool Steel Machining
For manufacturing dies, molds, and wear-resistant components, our tool steel machining capabilities are second to none. We work with grades like A2, D2, and O1, which are heat-treated to achieve high hardness and resist abrasion during heavy-duty operations.
Technical Specifications and Machining Power
We back our CNC steel production with a robust infrastructure designed for heavy-duty industrial applications. Our facility utilizes advanced CNC turning services and milling centers featuring live tooling, which allows us to perform multiple operations—drilling, tapping, and turning—in a single setup. This capability is essential for maintaining alignment and reducing production time for complex CNC machining steel projects.
For high-tolerance metal parts made from hardened steel or requiring intricate internal geometries, we employ Wire and Sinker EDM (Electrical Discharge Machining). This ensures we can process materials that are too hard for standard cutting tools without inducing thermal stress. Our integrated manufacturing base, which includes capabilities similar to a dedicated alloy casting foundry, enables us to handle large part dimensions and heavy workpieces that smaller shops simply cannot accommodate.
