High Power Core: 6000W-20KW laser range (20KW max cuts 30mm carbon steel/25mm stainless steel); 6000W entry power enables direct mid-thick material (10-15mm) cutting.
Key Specs: 4000×2000mm wide platform (100kg max load), ±0.03mm axis precision (maintained at 20KW power), 100m/min speed, double rack & pinion servo drive.
Efficiency: 1.0G acceleration + 20KW power cuts 20mm carbon steel 45% faster than 5KW low-power machines.
Fit: Heavy machinery/steel structures; 380V/50Hz for industrial high-power thick-sheet processing.

Advantage
High Power Threshold for Mid-to-Ultra-Thick Cuts: With a 6000W minimum power (vs. 1500W of standard models), the QH-4020F skips the "low-power limitation"—directly handling mid-thick materials (10-15mm carbon steel) without power strain, while 20KW max power tackles ultra-thick 30mm carbon steel. This eliminates the need for pre-cutting or secondary processing, reducing production steps and lowering costs by 30%-35% for thick-sheet-focused projects.
Wide Platform + High Power Boosts Large-Format Efficiency: The 4000×2000mm wide processing area allows one-time cutting of large thick workpieces (e.g., 4×2m 20mm stainless steel panels), while 20KW power cuts at 8-12m/min (vs. 3-5m/min for 5KW models). For example, a full 4×2m 18mm carbon steel sheet takes only 20-25 minutes to cut—halving the time of low-power machines and accelerating large-batch thick-sheet production.
High Power Maintains Precision for Thick-Sheet Quality: Unlike many high-power cutters that sacrifice accuracy for power, the QH-4020F’s double rack & pinion servo transmission ensures ±0.03mm precision even at 20KW. This is critical for thick-plate applications like steel structure joints, where cut accuracy directly impacts weld fit-up—reducing weld rework rates by 40%-50% compared to less precise high-power alternatives.
