Choose CNC Plasma When
- ✓Cutting mild or stainless steel 6–80mm
- ✓Budget is under $150K for machine + table
- ✓Need fast payback (under 18 months)
- ✓Running structural, fabrication, or job shop work
- ✓Need to cut up to 160mm thick plate
- ✓Operating cost per part is the primary metric
Choose Fiber Laser When
- ✓Cutting thin material (under 12mm) at high volume
- ✓Precision and edge finish are critical
- ✓Cutting stainless or aluminum sheet metal
- ✓No heat-affected zone tolerance is required
- ✓Running 2–3 shifts for fast ROI
- ✓Products require tight dimensional tolerances
Choose Waterjet When
- ✓Cutting sensitive materials (titanium, composites, stone)
- ✓No heat-affected zone is mandatory
- ✓Cutting very thick material (100mm+)
- ✓Mixed material facility (metals + non-metals)
- ✓Cutting reflective materials laser can't handle
- ✓Part integrity cannot tolerate thermal distortion
