Core Features
(1) Octagonal Optimized Design
• 8 - sided Symmetrical Structure: No blind spots, suitable for multi - angle welding by robots, reducing the need for turntables.
• High Space Utilization: Saves more space than a square tabletop while ensuring welding accessibility.
(2) Nitrided D28 Hole System
• Ultra - high Hardness: Surface nitriding treatment (gas or ion nitriding), hardness ≥ HRC50, and wear resistance is 3 - 5 times higher than that of ordinary cast iron.
• Rust and Corrosion Resistance: Suitable for the humid and oily environment in the automotive industry.
• D28 Large Bore: Compatible with heavy - duty positioning pins and fixtures, with stronger load - bearing capacity.
(3) 3D Omni - directional Positioning
• X/Y/Z Three - way Adjustment: Both the tabletop and sides are equipped with standard holes, supporting three - dimensional clamping.
• Modular Expansion: Multiple workbenches can be spliced to adapt to workpieces of different sizes.
(4) Robot Welding Optimization
• High Repeatable Positioning Accuracy (±0.05mm), ensuring the consistency of robot welding.
• Thermal Deformation Resistance: Cast iron + nitrided layer effectively resists high - temperature deformation during welding.
• Quick Change - over:Apply pneumatic/hydraulic fixtures to meet the cycle time requirements of automotive production lines.
This 1200×1200mm octagonal 3D flexible welding table is a high - end solution for automotive robot welding. With nitriding treatment, D28 heavy - duty hole system, and optimized octagonal design, it becomes an ideal choice for high - precision and high - efficiency automated welding.
