Columbia Manufacturing, Inc.'s precision CNC and conventional milling services produce components for a variety of industries including aerospace, turbine, and military/government. We offer 3D milling, 4-axis simultaneous milling, and 5-axis boring as well as horizontal, vertical, drilling, boring, counterboring, countersinking, gang drilling, pocketing, profiling, reaming, tapping, and thread milling. Our equipment includes vertical, horizontal, and horizontal boring mill machinery and with our full tool room and with EDM capabilities we can manufacture in-house custom tooling and fixtures.

Our 3, 4, and 5-axis capabilities enable us to produce components that measure up to 60" long, in widths that range from 1" to 30" and heights from 1" to 32". We work with a wide range of materials including alloy steels, aluminum, carbon steel, cobalt, nickel-chromium based superalloys, molybdenum, nickel alloys, stainless steel, and titanium allows us to meet the needs of our industrial clients. For CNC and conventional milling we maintain tightest tolerances of ± .0002".
