Semi-automatic Loading Ensures Bevel Precision for Irregular Heavy Tubes: Unlike fully-automatic systems limited by standard tube straightness, the semi-automatic workflow lets operators adjust for slight end irregularities (common in heavy steel pipes) before auto-clamping. The system’s consistent clamping force secures tubes in place, ensuring ±45° bevel angles stay within ±0.5° tolerance—critical for weld joint fit-up, and reducing bevel rework rates by 35%.

±45° Beveling Simplifies Long-Tube Welding Prefabrication: The machine’s beveling capability covers the full ±45° range needed for heavy tube welding (e.g., 30° V-bevels for wind tower flanges, 45° double-sided bevels for oil pipelines). Paired with ±0.03mm axis accuracy, it maintains uniform bevel depth and angle across 11500-12500mm long tubes—avoiding alignment errors from segmented beveling and cutting overall prefabrication time by 40%.

Cost-Effective Balance of Flexibility & Bevel Efficiency: Semi-automatic loading reduces upfront investment by 20-25% vs. fully-automatic horizontal lathes (no need for conveyor systems), while still cutting manual labor time by 50% vs. fully manual beveling. For medium-batch, multi-spec tube processing (e.g., mixing Φ200mm and Φ500mm tubes), it skips time-consuming automatic changeovers, keeping bevel production efficient without overspending on automation.

20T Frame & Horizontal Layout Stabilize Heavy-Tube Beveling: The 20T heavy-duty frame and horizontal lathe structure distribute weight evenly across 12m-long, 580mm-diameter tubes, minimizing sagging or vibration during ±45° beveling. This stability prevents bevel edge deformation (a common issue with lighter machines) and ensures the ±0.03mm precision is retained even for 20mm-thick wall tubes—guaranteeing weld strength in high-load applications like pressure pipelines.
