The CNC laser cutting system features a rigid steel frame with thermally stabilized components to maintain geometric accuracy during operation. Heavy-duty linear guideways support the cutting head assembly across X-Y axes, while servo-driven ball screws ensure precise positioning. The machine bed incorporates a slat or honeycomb design for optimal material support and scrap removal, with load capacities ranging from 500kg to 5000kg depending on model size.
Laser Source Technology
Modern systems utilize three primary laser types:
