Top Machine Shops in San Diego (CA)

Top Machine Shops in San Diego (CA) – With its naval and air facilities, San Diego has long been known as a military town, so it should come as no surprise that the city’s machine shops serve the demands of relevant government contractors in the aerospace, defense, and military sectors. Many of these businesses are classified as small or diversified businesses, which facilitates winning large government contracts. The region also has a large number of non-government manufacturing companies, such as Solar Turbines, and local machine shops step up to fill those orders as well.

Of course, CNC machining is the main activity, but many shops also provide traditional turning and milling services when necessary. Many businesses specialize in aerospace and defense work. Some people focus on Swiss-style machining for tiny parts. Numerous businesses also provide further related services, including EDM, fabrication and assembly, heat treatment, engineering, prototyping, and other machining services as required.
