CNC Machining

Everything you need to know about CNC machining — from precision milling and turning to multi-axis operations and surface finishing.

CNC (Computer Numerical Control) machining is a subtractive manufacturing process where pre-programmed software controls the movement of factory tools and machinery. It enables the production of complex, precision parts from metals, plastics, and composites with tight tolerances. From 3-axis milling to 5-axis simultaneous machining, CNC technology offers unmatched versatility for prototyping and production. Common operations include milling, turning, drilling, and EDM — each suited to specific geometries and material types. At OrderCAD, our CNC machining capabilities span a wide range of materials including aluminum, steel, titanium, brass, and engineering plastics. We deliver parts with tolerances as tight as +/-0.025mm, backed by full quality inspection reports.
