D28 Series Welding Fixture Table with 28mm Standard Hole Grid Layout

The D28 Series Welding Fixture Table with 28mm Standard Hole Grid Layout is an industrial heavy-duty 3D welding fixture platform built around the global universal 28mm hole grid standard. Featuring a full five-sided hole layout, it supports free combination of positioning blocks, quick locking pins and clamps to replace traditional single-purpose fixed jigs, greatly cutting jig production costs and shortening product changeover time. With strict precision inspection and two optional high-strength materials, this welding table delivers stable dimensional consistency for mass welding production and automated robot welding stations.

• Structure: One-piece box-type stiffener casting, 550℃ high-temperature annealing + vibration double aging, completely eliminating casting internal stress.
• Hardness: Working surface quenched HB180~220, weld slag does not easily adhere, vibration damping and stability.
• Advantages: Long-term high-temperature welding, heavy load, not easily deformed, long-term precision retention, suitable for large heavy industry and robotic welding workstations.
• Load capacity: Single table static load 5~10 tons.

• Process: Steel plate integral CNC milling, plasma nitriding treatment, nitriding layer 0.25~0.35mm
• Surface Hardness: Nitriding layer HV450~630, wear-resistant, anti-spatter, rust-proof and corrosion-resistant.
• Advantages: Lightweight, easy to transport, good toughness, commonly used in shipbuilding and vehicle frame mass production lines.

• Flatness: 0.1mm/1000mm
• Perpendicularity of Tabletop and Side: 0.1mm/200mm
• Hole Center Positioning Accuracy: ±0.03mm
• Convenience Feature: 1mm precision scale etched on the tabletop edge, eliminating the need for scribing for alignment.

1. Universal 28mm standard hole grid layout - This heavy duty 3D welding table uses 100 by 100 mm grid holes, fully compatible with all D28 modular fixtures. Standard jig accessories can be shared to cut procurement costs.
2. Five sided full hole three dimensional clamping - The D28 welding fixture table has holes on top and four vertical sides, supporting multi angle one time clamping for tubular frames and box parts to avoid repeated repositioning.
3. Strict high precision for mass welding - Flatness is controlled within 0.1mm per meter and hole tolerance stays at ±0.03mm. Consistent machining accuracy of this modular welding platform largely lowers product rework rate.
4. Superb load bearing for heavy structure processing - Reinforced box body greatly improves stability. Cast iron version holds 10 ton uniform load and steel version supports 6 ton load, suitable for engineering machinery and rail transit workpieces.
5. Greatly save jig cost and shorten changeover time - Flexible D28 welding fixture table replaces traditional fixed custom jigs. New product fixture assembly only takes 10 to 30 minutes and saves storage space for idle tooling.
6. Wear resistant surface with low maintenance cost - Paint free hard surface will not produce toxic fumes during welding and resist welding spatter. Simple daily cleaning can extend the service life of the 3D welding table.
