High Accuracy Grid Hole D28 3D Welding Positioning Workbench

The High Accuracy Grid Hole D28 3D Welding Positioning Workbench is a professional modular clamping platform built for precision metal fabrication, structural welding and component inspection. Centered on the standard D28 100mm uniform grid hole layout, this workbench delivers ultra precise hole positioning and flatness control to eliminate dimensional deviation during batch welding.

The whole tabletop is processed via full CNC milling and optional deep nitriding treatment to resist welding spatter, scratches and oxidation. Constructed with thickened Q355 high strength steel and internal dense reinforcing ribs, it maintains stable flatness without deformation under long term heavy load pressure.

The five sided perforated design enables full three dimensional clamping on top and four vertical sides, supporting flexible combination of all universal D28 fixtures, positioning pins and angle brackets. It replaces costly custom fixed jigs, shortens workpiece setup time and unifies processing standards for small batch trial production and mass welding lines. Complete CE certification can be provided to meet import standards for European and global industrial markets.

• Micron Level Grid Hole Precision Ensures Zero Dimensional Discrepancy
  All grid holes are processed by five-axis CNC machining center, with uniform hole spacing and tiny positioning tolerance. Every workpiece clamped on the table can maintain unified benchmark standards, drastically cutting the rate of defective finished products during continuous welding mass production.
• Five Sided Through Hole Layout Achieves Full Space Three Dimensional Fixing
  The through-hole structure covers the top surface and four vertical side plates of the workbench. Operators can lock workpieces horizontally, vertically or diagonally, which greatly simplifies the clamping process of irregular metal frames, tubular parts and mechanical chassis.
• High Temperature Nitriding Layer Greatly Extends Table Service Lifespan
  The integral nitriding process forms a compact hard protective layer on the entire table surface. It can effectively isolate welding spatter adhesion, prevent surface scratches and slow down oxidation rust, reducing daily maintenance frequency of workshop equipment.
• Universal D28 Grid Matches All International Standard Modular Fixtures
  The globally recognized D28 100mm grid layout is compatible with all mainstream D28 fixture accessories in the industry. Factories do not need to develop exclusive custom jigs for different workpieces, which lowers tooling development cost significantly.
• Reinforced Integrated Frame Prevents Permanent Deformation Under Heavy Load
  Thickened Q355 steel plates and cross internal rib structure enhance the whole table's structural rigidity. Even under long-term pressure and collision of heavy metal workpieces, the tabletop will not warp or sink, maintaining long-term stable flatness.
• Quick Fixture Combination Greatly Improves Workshop Operational Efficiency
  Modular fixtures can be assembled and disassembled within minutes, which largely reduces workpiece clamping preparation time. Less repeated manual calibration cuts labor input and shortens the whole production cycle to raise daily workshop output.

This high precision D28 grid hole positioning workbench covers multiple metal processing and heavy manufacturing fields. It is widely used for new energy equipment frame welding, vehicle accessory assembly, construction steel structure fabrication, logistics equipment processing, agricultural machinery part welding and metal mold repair work. It is suitable for prototype trial workshops, small-batch custom processing factories and automated robot welding stations, and can also serve as a dedicated measuring platform for workpiece dimensional detection.
