CNC Fiber Laser Cut Aluminum and Stainless Steel Parts

Fiber lasers focus a high-power beam to melt the sheet while assist gas blows the kerf clear. Nitrogen gives clean, oxide-free edges on stainless and aluminum, ready for welding or coating; oxygen cuts carbon steel faster but leaves an oxide layer. Parts are nested to minimize scrap, and small tabs hold them in the skeleton until removal. Fine features down to roughly the sheet thickness are achievable.

Aluminum reflects laser energy, so it is cut with fiber sources that handle reflective metals. Stainless 304 cuts cleanly with nitrogen and keeps its corrosion resistance. Carbon steel is the most economical and usually needs powder coat or paint. Heat-affected zones are narrow but can slightly harden edges. If edges must be bright and smooth, light grinding or tumbling follows cutting.

Cut parts are checked against the DXF with calipers and vision systems at first article, and edges inspected for dross. Critical dimensions are 100% verified before shipping. Finished parts can be bent, welded or machined further. Common uses include mounting plates, decorative screens, gaskets, nameplates, machine blanks and drone or robot chassis plates.
