High-Speed Core: 1.5G maximum linkage acceleration + 100m/min speed; cuts empty travel time by 50% vs. 1.0G machines, ideal for batch processing.
Key Specs: 4000×2000mm large area (100kg max load), ±0.03mm axis precision (maintained at high speed), 1500W-20KW power (0.5-25mm material cutting).
Stability: Double rack & pinion servo transmission prevents vibration during 1.5G acceleration, ensuring consistent cut quality.
Fit: Auto parts/batch hardware production; 380V/50Hz industrial compatibility.

Advantage
1.5G Acceleration Boosts Batch Throughput: The ultra-high 1.5G linkage acceleration enables rapid transitions between cutting features—for example, when processing a 4×2m sheet with 500+ small holes, it reduces total cycle time by 30%-40% compared to machines with 1.0G acceleration. This is a game-changer for mass production (e.g., auto component batches), where every minute of process time directly impacts output.
High-Speed Cutting Without Precision Loss: Thanks to the double rack & pinion servo transmission (low backlash and high rigidity), the machine maintains ±0.03mm axis accuracy even when accelerating at 1.5G and moving at 100m/min. Unlike low-end high-speed machines that sacrifice precision for speed, the QH-4020F ensures consistent cut edges (no burrs or dimensional 偏差) for high-tolerance parts (e.g., electrical cabinet frames).
Large-Format High-Speed Efficiency: For 4×2m oversized sheets (common in structural hardware), the 1.5G acceleration eliminates slow motion delays when traversing the large workspace. Cutting a full 4m-long straight edge takes just 4 seconds (at 100m/min), vs. 6 seconds with 1.0G acceleration—summing to significant time savings for multi-feature large workpieces, while the 100kg load capacity handles heavy thick sheets without speed reduction.
