D28 Series Standard 3D Welding Fixture Table 28mm Hole System
The D28 Series Standard 3D Welding Fixture Table with 28mm Hole System is a heavy-duty, modular, precision welding platform based on a 100×100mm orthogonal grid and Φ28mm positioning holes. Commonly known in the industry as the "D28 welding platform," it represents a mainstream heavy-duty standard within 3D flexible welding systems and is suitable for the positioning, clamping, welding, and assembly of heavy steel structures, machinery frames, and thick-plate workpieces.
Hole System Specifications
Specification
Details
Hole Diameter
Φ28mm (tolerance typically ±0.02mm to ±0.05mm)
Hole Grid Spacing
100mm × 100mm (tolerance ±0.05mm)
Positioning Datums
Precision machining on 5 surfaces (top face + 4 sides); fully interconnected hole matrix; supports 360° 3D clamping
Comparison with D16 Series: The D16 series features Φ16mm holes and a 50×50mm grid, making it suitable for small, precision components. The D28 welding table is designed for heavy-duty applications, offering approximately double the load-bearing capacity and about 50% greater clamping force compared to the D16 welding table.
Structural Design
Tabletop Thickness: Standard 25mm, with heavy-duty options up to 30mm
Reinforcement: Dense array of underside reinforcing ribs
Load Capacity: 2t/m² (5t/m² for frame-style models)
Sides: All four sides feature 100mm grid hole pattern with 200mm height
Modularity: Supports vertical or horizontal clamping and modular expansion through connection of multiple welding tables.
Standard Configuration (2000×1000mm)
3D Welding Table: 2000×1000×25mm, Q355 material, nitrided finish, Class 1 precision
Support: 4 adjustable support legs (M24, ±50mm travel)
Accessories (Basic Set):
Φ28 locating pins (10 pcs)
Quick-action clamps (4 pcs)
L-shaped positioning squares (2 pcs)
Reference blocks (2 pcs)
Grounding cable (1 set)
