CNC Machining Materials: Steel, aluminum, plastics, brass, copper, hastelloy, titanium and exotic materials  YouTube   Facebook We machine more than 20 engineering-grade metal and plastic materials. There are limitations on the sizes and thicknesses of some metals and plastics because not every part can be made in every material. Custom machining consists of a surprisingly diverse set of works. With seemingly endless options for customization, materials, and techniques, cnc machining can produce parts for many industries and people's needs. We use the newest 5 axis cnc equipment (Haas UMC 750 and Haas VF-5SS ) as well as all fashioned conventional lathe and milling machines (Bridgeport, Hardinge). If you require a material that is not on the list or have specific questions, please let us know and call our cnc machine shop ( we do not machine wood parts). We provide Turning and Milling, 3 axis , 3+2 axis & continuous 5 axis cnc machining. We accept both small and large run jobs, Minimum quantity for order is 1. Short lead times are often available 2-3 days. Standard lead time is 2 weeks.
