High Light 5-side machined welding table ，welding table for engineering machinery ，welding fixture table with machining
D28 5-Side Machined Welding Table for Engineering Machinery Part
D28 5-Side Machined Welding Table for heavy-duty engineering machinery components

Designed specifically for heavy-load production of engineering machinery components, the D28 5-Side Machined Welding Table features complete five-side CNC precision machining. The table includes standard D28 Φ28 H7 hole grids distributed on the top working surface and all four side walls.

Subjected to strict stress-relief treatment and ion nitriding at HV550-900, the table maintains excellent flatness and hole-position accuracy under heavy cyclic loading. It allows flexible 3-dimensional clamping for excavator arms, chassis, brackets, and other thick-plate structural workpieces.

Compatible with the full series of D28 modular fixtures, it supports multi-table splicing for oversized parts and seamless integration with robotic welding cells, serving as a high-efficiency alternative to costly dedicated welding jigs.

Hole Details
  • Hole diameter: Φ28H7, hole spacing 100±0.05mm, through-hole design for easy removal of welding slag and cleaning
  • Compatible with M16 bolts and Φ28 locating pins
  • C3 chamfer at the hole opening ensures smooth insertion and removal of pins/bolts without scratching
  • Integral nitriding of the hole wall, HV550-900, provides wear resistance and prevents hole bulging or wear
  • Ensures long-term stable repeatability and positioning accuracy
Key Product Features
D28 welding table showing five-side machining and hole grid system Close-up view of D28 hole system and precision machining
1. All five sides are perforated and precision-machined
The top surface and four sides all feature D28 standard grid holes. Workpieces can be laid flat, mounted upright, or clamped at an angle, enabling multi-angle assembly and welding. Perfectly compatible with irregularly shaped frames and boom-like parts in engineering machinery. Squares, positioning blocks, and supports can be directly mounted on the sides without additional backing plates or brackets.
2. Heavy-duty rigidity for thick plates and large parts
The D28 hole system offers higher strength than D16, suitable for welding thick steel plates and heavy castings. Impact resistant, resists welding heat deformation, ensures interchangeability accuracy for batch parts, and can be integrated with robotic automated welding workstations.
3. Nitriding process enhances durability
Nitriding hardens the holes and working surfaces, preventing welding spatter from adhering to the worktable and reducing grinding and cleaning workload.
4. Modular and flexible tooling reduces costs
A single welding workbench, equipped with standard fixtures (locating pins, squares, clamps, and support blocks), replaces numerous dedicated welding jigs. This allows seamless switching between different types of engineering machinery parts with short tooling adjustment times, making it suitable for multi-variety, small-batch production.
5. Multifunctional design
A single welding table simultaneously performs welding, assembly, dimensional inspection, grinding, and drilling processes, eliminating the need for repeated workstation changes.
Usage and Maintenance Guidelines
  • Do not perform gas cutting directly on the welding table; high-temperature gas cutting will cause localized annealing, damaging the nitrided layer and causing localized deformation
  • Clean welding slag promptly; do not allow thick layers of slag to accumulate as this will elevate the workpiece and lead to inaccurate positioning
  • Do not hammer or strike the table surface or openings; when tapping or correcting the workpiece, place it on a support block, not directly on the table itself
  • Regularly clean welding slag from through-holes to prevent pin jamming
  • Recheck the flatness annually; for heavy-load conditions, a recheck every six months is recommended

Built for heavy-duty engineering machinery component fabrication, our D28 5-Side Machined Welding Table supports custom sizes, material options, and robotic-ready precision.
