QH-GC3-H 3-Chuck Heavy Duty Lathe Tube Cutting Machine Fully-automatic Loading Beveling Cutting

Fully-automatic Loading Drives High-Volume Efficiency: Unlike semi-automatic models that rely on manual feeding (slow and error-prone for long/heavy tubes), the QH-GC3-H’s fully-automatic system handles 11500-12500mm long tubes and 580mm large-diameter tubes end-to-end. It reduces loading/unloading time per tube by 80% and enables 24/7 continuous operation—critical for large-batch orders (e.g., 500+ oil pipeline sections) where throughput directly impacts project timelines.

±45° Beveling Ensures Weld-Ready Precision: The machine’s ±45° beveling range (with consistent angle accuracy) creates weld-ready joints directly during cutting. For thick-walled tubes (e.g., 20-50mm carbon steel for steel structures), this eliminates secondary beveling steps that often introduce dimensional errors—reducing weld joint rework rates by 50%-60% and ensuring compliance with strict industrial welding standards (e.g., API for oil pipelines).

3-Chuck Heavy-Duty Synergy with Auto-Bevel Capability: The 3-chuck lathe structure (paired with 20T machine weight) minimizes tube deflection during processing—even for 12500mm long, 580mm diameter tubes—while the fully-automatic system maintains ±0.03mm precision. This synergy ensures uniform bevel quality across the entire tube length (no angle deviation at tube ends) and supports seamless switching between round and square tubes (no fixture adjustments). For mixed orders (e.g., 300pcs Φ500mm round tubes + 200pcs 500×500mm square tubes), it boosts production efficiency by 35%-45% vs. single-format machines.
