What is Laser Cutting Technology?
Laser cutting is a non-contact process that uses a focused laser beam to melt, burn, or vaporize material. It offers unmatched accuracy, fine detailing, and minimal material waste—especially for sheet metal fabrication.
Key Features of Laser Cutting Technology:
- Highly accurate and consistent cuts
- Low material wastage
- Compatible with a wide range of materials
- Faster than conventional machining
- Integrates with CAD/CAM workflows
How Does a Laser Cutting Machine Work?
A laser cutter directs a high-energy beam through mirrors and lenses onto the material, following a pre-programmed CNC path for precise cutting.
Step-by-Step Laser Cutting Process:
- 1. Material Preparation: Select suitable sheet metal and perform hardness testing.
- 2. CAD Design: Create drawings with GD&T specifications.
- 3. Laser Beam Generation: Fiber, CO₂, or Nd:YAG laser generates a focused beam.
- 4. Cutting Execution: Laser melts or vaporizes metal along CNC-controlled paths.
- 5. Bending (If Required): Calculate bend allowance and form the part.
- 6. Inspection: Validate dimensions with GD&T checks.
