D28 Precision 3D Welding Table with Millimeter Graduation Scale
The D28 Precision 3D Welding Table with Millimeter Graduation Scale
is a modular fixture base designed for heavy-duty steel structures
and automated robotic welding lines. The table features a
monolithic design precision-machined on five faces via CNC; it
utilizes a standardized Φ28 positioning hole system combined with
precise 1mm coordinate scales on the sides, enabling rapid 3-axis
workpiece positioning without the need for additional measuring
tools. Through a dual stress-relief process and a wear-resistant
vacuum-nitrided surface, the table maintains micron-level flatness
accuracy even under long-term heavy loads and continuous
high-temperature welding. It is fully compatible with the entire
D28 fixture range, supports flexible batch welding for diverse
workpieces, and is a preferred choice for high-precision welding
fixtures in overseas factories.

Hole-Basis System & Surface Treatment

- Process Type: Gas Nitriding
- Total nitriding depth: 0.28-0.35 mm (surface hardened layer: 0.08 mm)
- Surface hardness: HV 550-800 (compared to just HV 180 for standard black-oxide
finished carbon steel), resulting in a threefold increase in wear
resistance
- High-temperature resistance: Withstands short-term exposure to 800°C welding spatter without
surface damage, whereas standard paint or black-oxide finishes peel
and rust immediately upon exposure to high heat
Process integrating millimeter graduations with the coating:
Processing sequence: CNC surface milling → deep laser engraving of
graduations → overall nitriding. The engraved grooves remain
exposed (uncovered by the nitriding layer); with a groove depth of
0.15 mm for the 1 mm graduation lines, the markings remain clear
despite welding spatter or repeated cleaning with wire brushes. (In
contrast, low-end tables apply the coating before engraving, making
the markings highly susceptible to rust and wear.)
Safety Structural Design
- Rounded Corners and Edges: The four corners of the welding table tabletop and the edges of
the side panels feature an R5 radius to prevent worker injury from
bumps or scratches, complying with Machinery Directive 2006/42/EC
- Load-Bearing Safety Margin: The D28 welding table supports a uniformly distributed load of 5
tons/m² with a structural safety factor of 2.5, far exceeding daily
operational requirements
- Non-Slip Work Surface: A nitrided, matte, textured surface prevents workpiece slippage
during welding, eliminating the need for additional anti-slip mats
- Safe Lifting: Features four symmetrical threaded lifting points (single-point
lifting is prohibited); the manual specifies load limits to
mitigate the risk of deformation during transport and lifting
- Arc Protection: The tabletop utilizes a non-conductive layered structure to
minimize damage to CNC equipment and robots caused by stray welding
currents
FAQ
What sizes are in stock? Can I customize dimensions?
Standard ready sizes: 1000×800, 1200×1200, 1500×1000, 1500×2000,
2000×3000, 2000×4000. Custom length, width, 300mm tall side plates
and 50×50 dense hole grid are acceptable with a 15-25 working day
lead time.
Is your D28 system compatible with Siegmund fixtures?
100% interchangeable. Our Φ28H7 hole standard follows international
industry norms, fully compatible with all mainstream D28 brand
accessories.
How long is the warranty period?
12-month warranty for the whole table body against manufacturing
deformation and hole tolerance defects. Consumable accessories like
clamps and pins carry a 12-month warranty; spare parts are supplied
at factory cost long-term.
Can we print our company logo on the welding table or accessory
kits?
OEM logo service is supported. We can laser engrave your brand logo
on table edge or customize color boxes for fixture kits with your
branding, no extra mold charge for large orders.
Which HS code do you use for customs declaration? Can you adjust HS
code as our customs demand?
Standard HS code: 73269000. We can issue commercial invoice,
packing list matching your designated HS code if your local customs
has special regulations.Cut down your welding fixture setup time
