CNC Machining & Routing
High-yield 4x8 ft CNC machining and routing cells engineered for precision profiling, pocketing, tapping, and sheet metal parts fabrication right from scratch.
Turnkey CNC Routing & Milling Solutions
At Lumicision, our precision CNC capabilities complement our laser fleet to provide complete end-to-end component manufacturing right from raw sheet stock. With a dedicated 4x8 ft CNC bed capacity that can accommodate even larger format materials, we handle everything from rapid one-off mechanical prototypes to recurring production batches.
Why Combine CNC Machining with Laser Services?
- Zero-Heat Material Processing: For thick aluminum plates, engineered plastics, and delicate hardwoods sensitive to thermal distortion, our high-speed CNC routers deliver clean, stress-free edges without thermal discoloration.
- Complex Multi-Depth Machining: CNC milling allows stepped pockets, countersunk holes, threaded blind holes, and precision o-ring grooves that cannot be produced with 2D cutting alone.
- Large Format Capability: Our 4x8 bed handles full-size industrial sheets with automatic tool changer efficiency, reducing material handling and optimizing sheet yield.
- Turnkey Production from Scratch: Receive fully cut, pocketed, deburred, and finished parts ready for direct assembly or secondary press brake bending.
Compatible Materials & Alloys
Our laser systems are optimized with assist gases (Nitrogen, Oxygen, Shop Air) and beam frequency controls for clean cuts across:

Frequently Asked Technical Questions
What is your maximum machining envelope on the CNC router?
Our standard machining envelope is 4 ft x 8 ft (1220 mm x 2440 mm), but our open-bed clearance design accommodates oversize stock up to 5 ft wide and continuous nested lengths for architectural panels and industrial structural frames.
When should I choose CNC machining over laser cutting for plastics?
CNC routing is ideal for engineering plastics that cannot be thermally laser-cut due to toxic gas release or melting (such as PVC, polycarbonate over 0.25", UHMW-PE, and carbon fiber), as well as parts requiring pocket depths, chamfers, countersinks, and threaded blind holes.
Can Lumicision tap threads and drill precision counterbored holes?
Yes. Our CNC centers perform multi-tool drilling, rigid tapping, countersinking, counterboring, and 3D surfacing in a single setup, delivering finished parts ready for final assembly.
Do you supply raw aluminum plates or can customers provide their own stock?
We offer both turnkey sourcing with comprehensive material test certificates (MTRs) and toll-machining on client-supplied sheet, plate, or extruded billet stock.
Have CAD Files Ready?
We accept STEP, STP, DXF, DWG, AI, and PDF drawing packages for instant tooling & turnaround evaluation.
