Laser Cutting
High-power CNC fiber and CO2 laser cutting delivering clean edges, intricate geometries, and zero mechanical tool wear on sheet metals, plastics, and composites.
Precision CNC Laser Cutting Capabilities
Lumicision provides industry-leading laser cutting solutions designed for rapid turnaround and uncompromising part accuracy. Our high-power laser systems direct focused energy with optical precision, vaporizing and blowing molten metal away with clean assist gases (Nitrogen, Oxygen, and Shop Air).
Why Choose Lumicision Laser Cutting?
- Zero Tool Wear & Contactless Cutting: Unlike mechanical shearing, punching, or milling, lasers do not deform or stress delicate workpieces.
- Micro-Kerf Efficiency: Thin cut widths allow tight nesting of complex parts, drastically lowering expensive raw material scrap.
- Burr-Free Finishes: Clean cuts mean little to no secondary deburring or post-processing is required prior to welding or finishing.
- Fast Turnaround: Direct CAD-to-cut digital workflow ensures parts are in production minutes after file validation.

Frequently Asked Technical Questions
What is the maximum plate thickness Lumicision can laser cut?
Our 6kW CNC fiber laser and dual-source CO2 systems (5'x10' bed) can cleanly cut up to 1.0 inch (25.4 mm) in carbon steel, 0.75 inch (19 mm) in stainless steel, 0.50 inch (12.7 mm) in aluminum, and up to 1.0 inch in cast acrylic and engineering plastics.
What edge quality can I expect on stainless steel and aluminum?
We utilize high-purity high-pressure Nitrogen (N2) assist gas for stainless steel and aluminum, resulting in bright, dross-free, oxide-free edges that are immediately ready for powder coating, anodizing, or TIG/laser welding without mechanical grinding.
What tolerances can Lumicision maintain on laser-cut sheet metal parts?
We consistently achieve positioning accuracy of ±0.001 inch (±0.025 mm) and typical feature dimensional tolerances of ±0.002 to ±0.005 inches depending on material grade, thickness, and nest geometry.
Can you provide rush turnaround for emergency or R&D prototype parts?
Yes. With extensive in-stock sheet inventory and rapid CAD file processing, we offer expedited 24 to 48-hour turnarounds for prototyping and mission-critical production runs throughout Toronto and the GTA.
Have CAD Files Ready?
We accept STEP, STP, DXF, DWG, AI, and PDF drawing packages for instant tooling & turnaround evaluation.
