3D D28 Welding Table with Five Sided Machined Working Surfaces

3D D28 Welding Table with Five Sided Machined Working Surfaces
3D D28 Welding Table overview showing precision machined surfaces and locating holes

The 3D D28 Welding Table with Five-Sided Machined Working Surfaces is a heavy-duty modular 3D welding fixture table. Its top surface together with four vertical side faces are all CNC-machined working datums, fitted with Φ28 mm H7 locating holes in 100 mm grid pitch. Complete stress-relief treatment minimizes structural deformation. Material options include Q355 steel and HT300 cast iron. Optional ion nitriding delivers high hardness against welding spatter and wear. This welding table supports multi-direction clamping and inter-table splicing, fully compatible with global D28 fixture accessories, ideal for heavy fabrication and robotic welding cells.

Production Process
Manufacturing process showing CNC machining and precision boring operations
  1. Steel plate/cast iron blank, artificially aged to relieve stress and prevent later deformation
  2. CNC five-sided milling, top surface + four sides are all milled flat
  3. Precision boring of D28 standard holes
  4. Shot blasting; nitriding hardening treatment optional
  5. Bottom surface reinforcing rib structure to ensure rigidity; millimeter scale can be engraved around the perimeter
Main Advantages
  • Five-sided clamping: Not only the top surface, but also the four vertical sides can be used to fix the fixture, achieving vertical and oblique workpiece positioning, making welding of complex frames, boxes, and chassis very convenient
  • Expandable platform: Any side can be connected to another welding table, infinitely expanding the work area
  • Flexible tooling, replacing dedicated fixtures: With positioning pins, quick clamps, corner blocks, V-blocks, and heightening blocks, new products do not require re-designing welding tooling; tooling changeover can be completed in tens of minutes, making it very cost-effective for small-batch, multi-variety production
  • High precision and good repeatability: Suitable for manual welding and robotic welding workstations
  • Nitrided version welding station: Resists weld slag spatter, is not easily damaged by impacts or wear, and has a long service life
FAQ
Q: Is ion nitriding treatment mandatory?
A: No, it is optional. Shot-blasting is the basic finish. Ion nitriding reaches surface hardness HV550-900, greatly improves anti-spatter, wear-resistant and anti-rust performance, extending table service life. It is strongly suggested for high-volume welding workshops.
Q: Are your tables compatible with mainstream D28 fixture accessories?
A: Yes. Our 3D D28 welding table is fully interchangeable with global standard D28 fixture accessories including locating pins, angle blocks, clamps, V-blocks and splicing connectors. You can reuse your existing D28 tooling sets.
Q: Can multiple tables be spliced together for a larger working area?
A: Yes. Thanks to five-sided machined side datums, tables can be connected side-by-side with special splicing pins. Do not tighten tables only by bolts, otherwise table deformation will occur. We can control accumulated splicing tolerance upon request.
Q: Are table legs and clamping accessories included in table price?
A: No. The quoted price is for table top only. Table legs, adjustable feet and all fixture accessories are ordered separately. We can supply complete one-stop packages.
Q: Can you provide inspection & measurement protocol?
A: Yes. We can supply factory inspection report covering flatness, side perpendicularity and hole-position tolerance. For nitrided tables, hardness test record is also available.
Q: What size options are available?
A: Standard dimensions range from 1000×800 mm to 4000×2000 mm. Custom sizes are acceptable. For dimensions over 4000 mm, multi-table splicing solution is recommended for manufacturing and shipping consideration.
Q: What causes accuracy loss of welding table?
A: Main reasons include insufficient stress-relief treatment, operating without proper leg levelling, heavy hammer striking working surface, arc burning locating holes and long-time local high-temperature baking. Please follow our operation & maintenance instructions.
