CNC (Computer Numerical Control) Machining is a high-precision, subtractive (meaning we remove material, not add it, like in 3d printing – or additive) manufacturing process where pre-programmed computer software spins milling tools (metal, carbide, diamond tipped, etc.) at high spin rates to remove material in very precise cuts.  Modern CNC manufacturing utilizes advanced CAD models translated into G-code (geometric toolpaths) and M-code (miscellaneous machine functions) to automatically carve parts from solid blocks of raw material. Most of the encoding can be done with advanced software, but human machinists play a critical role in understanding what is technical feasible, and what isn’t.

This process is critical for producing flight-grade, high-reliability components across the aerospace, defense, and industrial sectors. Multi-axis CNC machining centers—ranging from standard 3-axis mills and lathes to highly complex 5-axis systems—hold strict tolerances down to ±0.0001 inches, retaining 100% of a material’s native structural integrity. It is widely utilized to shape demanding metals like titanium, aluminum, steel, and high-temperature Inconel for turbine blades or landing gear, as well as rugged engineering plastics like Delrin, ABS, and PEEK for industrial bearings, seals, and electronics housings.
