D28 Series Heavy Duty Modular Nitrided 3D Welding Table

The D28 Series Heavy-Duty Modular Nitrided 3D Welding Table is a flexible 3D tooling platform designed for industrial-grade heavy-duty welding and precision assembly. Centered on a configuration of standard φ28mm positioning holes, a 100mm grid pattern, five working surfaces, and a nitrided hardening treatment, it excels in heavy-load capacity, high precision, superior wear resistance, and versatile 3D clamping, making it ideal for heavy workpieces, large structural components, and high-load production lines.

• Support: Each 3D welding table is equipped with standard adjustable legs (±50mm leveling adjustment), a fixed steel frame, or a mobile stand with casters
• Expansion: Multiple welding tables can be joined together to accommodate the welding of extra-long or extra-wide workpieces

• Tooling Costs: Replaces dedicated fixtures, saving over 90% on design and manufacturing expenses
• Rework Costs: High-precision positioning reduces the scrap rate by more than 60%
• Maintenance Costs: Nitrided for wear resistance; requires no major overhaul for 10 years, with annual maintenance costs under 500 RMB

• Changeover Time: Modular, rapid reconfiguration cuts changeover time by over 80%
• Clamping Efficiency: Five-sided positioning allows complex workpieces to be processed in a single setup, boosting efficiency by over 50%
• Production Capacity: Compatible with flexible production lines, increasing capacity by 30%-50%

• Size Selection: Determine based on the workpiece's maximum length and width plus clamping clearance, allowing an extra 200-300 mm margin
• Material Selection: Choose nitrided Q355 steel for heavy-duty, high-frequency applications; choose nitrided HT300 cast iron for high rigidity and low vibration
• Accuracy Grade: Select standard accuracy (flatness: 0.1 mm/1000 mm) for general industrial use; select high accuracy (0.05 mm/1000 mm) for precision welding or inspection tasks
• Accessory Configuration: Basic setups include locating pins, right-angle brackets, and quick-action clamps; complex operations may require additional pneumatic clamping systems and angle-adjustment brackets
• Surface Treatment: Prioritize nitrided 3D welding tables (offering high hardness and excellent wear resistance); opt for standard black oxide or paint finishes only if the budget is limited
