High-Speed Core: 1.5G maximum linkage acceleration enables fast tube cutting/traversal; paired with ±0.03mm precision for speed without accuracy loss.​

Shared & Variant Specs: Both cut round Φ15-500mm/square 15×15-500×500mm tubes (5500-6500mm length); QH-GZ: 6000W-20KW/2T/9620×2950×2080mm (heavy-duty high-speed); QH-GS-6012:1500W-20KW/1.7T/8500×1380×2050mm (compact high-speed).​

Semi-auto Fit: Manual tube positioning + auto clamp/cut; ideal for custom batches—1.5G cuts batch processing time vs. standard-speed semi-auto machines.

1.5G Acceleration Cuts Batch Time by 35%-45%: The high-speed linkage drastically reduces processing duration for long tubes—for example, cutting 50 6500mm-long Φ200mm carbon steel tubes takes 2.5 hours (vs. 4+ hours with 1.0G standard machines). This efficiency gain is critical for small-to-medium batches, where rapid turnaround enhances productivity without the high cost of fully automated high-speed systems.​

High Speed Maintains ±0.03mm Precision: Unlike low-cost high-speed cutters that sacrifice accuracy for speed, the QH-GS’s side-mounted lathe minimizes vibration during 1.5G operation, while laser-guided alignment (paired with semi-auto manual adjustments) corrects minor tube misalignments. Even when cutting thin-walled tubes (0.5mm aluminum) at maximum acceleration, the machine retains consistent precision, reducing scrap rates by 20% vs. unstable high-speed alternatives.​

Model-Specific High-Speed Adaptability: QH-GZ leverages 6000W-20KW power + 1.5G acceleration to tackle thick-wall tubes (15-25mm) at speed—its 2T sturdy frame prevents deflection during fast cutting of heavy workpieces, a capability lightweight high-speed machines lack. QH-GS-6012, meanwhile, delivers 1.5G efficiency in 8500mm-length workshops (vs. 10m+ space needed for fully automated high-speed cutters), making high-speed processing accessible for small-scale facilities.​

Semi-auto + High Speed Balances Flexibility & Speed: Fully automated high-speed cutters require 30+ minutes of programming for custom tube sizes; the QH-GS’s semi-auto loading lets operators switch between Φ50mm and Φ300mm tubes in 5 minutes (manual positioning + auto high-speed cutting), retaining 1.5G efficiency while adapting to bespoke orders—filling the gap between slow manual machines and inflexible fully automated high-speed systems.
