Metal CNC

Metal CNC is the precision processing of metallic materials using computer-controlled cutting tools. Metals provide the highest strength, durability, and temperature resistance of all engineering materials. Common metals include aluminum, steel, stainless steel, titanium, brass, copper, bronze, magnesium, tungsten, Inconel, and specialty alloys.

CNC metal machining encompasses milling, turning, drilling, boring, grinding, and EDM. Tolerances range from ±0.02-0.05mm standard. Applications include aerospace structural components, automotive engine parts, medical implants, industrial equipment, electronics, and mechanical components.
