D28 Modular Fixturing Table with Five-Sided Precision Machining

Looking for a rigid, high-precision 3D fixturing table for heavy welding jobs? Our D28 Modular Fixturing Table with Five-Sided Precision Machining comes with fully machined top and four side walls to offer full three-dimensional clamping capacity.

Standard D28 hole grid enables quick assembly of locating blocks, clamps and supports, while nitrided surface resists weld spatter, scratches and rust. Two material options meet light/heavy load demands, perfectly matching automated robot lines and manual workshop production.

Cut fixture changeover time by over 60% and eliminate repeated custom jig costs with our five-sided precision modular worktable.

• Flatness: 0.02-0.1 mm/1000 mm (max. 0.1 mm/m for large tables), ensuring stable dimensional tolerances for welded workpieces.
• Side-wall perpendicularity: 0.1 mm/200 mm; sides are strictly perpendicular (90°) to the table surface, ensuring error-free positioning with right-angle fixtures.
• Hole position accuracy: Center-to-center tolerance of ±0.03-±0.05 mm for all system holes; inner hole walls are fully precision-machined.
• Hole diameter tolerance: Φ28.065-Φ28.149 mm, ensuring smooth insertion/removal of positioning pins without play and maintaining precise repeatable positioning.
• Surface roughness: Ra 1.6-Ra 3.2; facilitates easy removal of welding spatter and ensures strong adhesion for wear- and corrosion-resistant coatings.

• Heavy Construction Machinery: Welding of excavator, crane, and loader frames
• Rail Transit: Freight car bodies, vehicle frames, and track-related steel structural components
• Automotive Manufacturing: Truck chassis, bus frames, and new energy battery frames
• Steel Structures / Pressure Vessels: Pipe supports, enclosures, and equipment frames
• Robotic automated welding workstations, precision assembly, and dimensional inspection stations
• Mass production of frames for ships, agricultural machinery, and large-scale equipment
