Precision Machining Services
Tight-tolerance machining of stainless, cobalt, tool steels, and cast iron.
Overview
Our machining department complements Coronado’s casting and fabrication operations, providing customers with a single, reliable source for precision-machined components and assemblies. We perform lathe work—including OD and ID turning, facing, and boring—as well as milling and drilling for both rough and finish machining across a wide range of stainless steel and high-alloy materials.
This in-house machining capability ensures tight control over tolerances, surface finish, and lead time, reducing the need for outsourcing and delivering consistent, high quality results from casting to finished part.
