High Power Enables Thick-Plate One-Pass Processing: The 6000W-20KW range eliminates the need for multi-pass cutting of thick plates—for example, 25mm carbon steel (a challenge for low-power machines) is cut in one pass at 12-15m/min, reducing processing time by 50%-60% vs. 3000W machines that require 2-3 passes. This also ensures consistent cut quality (no edge jaggedness from repeated heating) for thick-plate weld joints.​

High-Power Beveling for Thick Workpieces: Unlike low-power models that struggle with ±45° bevels on >10mm plates, the QH-3015F-BG’s 6000W+ power delivers deep, smooth bevels on 10-25mm thick metal. For instance, 20mm stainless steel U-type bevels are completed in a single operation with ±0.5° angle accuracy, avoiding the need for post-bevel grinding and cutting weld prep time by 40%.​

Precision Retention Under High Power: The double rack & pinion servo transmission maintains ±0.03mm axis accuracy even during high-power (20KW) thick-plate cutting—critical for large workpieces (e.g., 3m-long 20mm steel plates) where slight deviations would ruin bevel alignment. This precision reduces scrap rates by 30%-35% compared to high-power machines with less stable transmission systems.​

Efficient High-Power Workflows: The combination of 6000W-20KW power, 1.0G acceleration, and 100m/min speed creates a high-throughput system—batch processing 10 pieces of 3000×1500×15mm carbon steel plates (with ±30° bevels) takes ~2.5 hours, vs. 4+ hours with 3000W machines. The semi-enclosed design also minimizes downtime from cleaning high-power cutting debris, further boosting productivity.
