D28 H7 modular welding table

,H7 hole welding table
Our D28 H7 hole modular welding table is a heavy-duty 3D flexible fixturing platform built for precision metal fabrication. Engineered around the global standard φ28 H7 precision hole system on a 100 mm × 100 mm grid, it delivers consistent repeat positioning for fit-up, tack welding, assembly and inspection work. Available in 2D single-sided and 3D five-sided configurations, this modular welding platform supports fast fixture reconfiguration and seamless interconnection between tables for oversized workpieces. Choose stress-relieved Q355 steel with gas nitriding or thermally stable HT300 cast iron to match your workshop needs, fully compatible with mainstream D28 clamping accessories.
| Parameter | Specification |
|---|---|
| Hole Grid | 100 mm × 100 mm equidistant grid (50 mm × 50 mm for the D16 series) |
| H7 Hole Tolerance | φ28 H7, with strictly controlled hole dimension tolerances. Compatible with M16 locating pins and quick-locking pins; interchangeable with accessories from global brands such as Siegmund and Demmeler |
| Table Types | 2D Welding Table: Holes on the top surface only. 3D Welding Table: Holes on the top surface and all four sides (5 working surfaces total), enabling multi-angle clamping across X, Y, and Z axes — ideal for complex frames, racks, and robotic welding applications. |
| Material Options | HT300 Gray Cast Iron: Excellent vibration damping and minimal thermal deformation; high precision, commonly used for robotic welding. Q355 Low-Alloy High-Strength Steel: Higher load-bearing capacity; the standard choice for export. Can undergo nitriding treatment (HV 550–900) for resistance against weld spatter, wear, and rust. |
| Flatness | Standard ≤0.1 mm/1000 mm; high-precision (Grade 0) can reach ≤0.05 mm/1000 mm |
| Load Capacity | Designed for medium-to-heavy workpieces. Each leg supports 700–1000 kg, with a total static load capacity of 3–10 tons for the entire table. While the D16 series is geared toward smaller sheet metal components, the D28 welding table is primarily designed for steel structures, vehicle frames, heavy machinery, and industrial racks. |
| Aging Treatment | Subjected to artificial stress-relief aging to neutralize thermal shock from welding, ensuring the table remains resistant to warping or deformation during long-term use. |
Three-stage CNC precision machining (unlike many products on the market that undergo only a single milling pass): rough milling → aging → semi-precision milling → precision reaming of H7 holes.
- Hole walls are precision-reamed individually to ensure a φ28 H7 tolerance.
- Grid markings: Metric (mm) scale; imperial (2-inch) grid markings are also available upon request.
- Controlled side perpendicularity: The perpendicularity between the side faces and the top surface is ≤0.1 mm/200 mm, ensuring reliable vertical positioning when used in 3D five-sided setups.
- Packaging: Large surface plates are packed in fumigation-free solid wood crates or export-grade plywood crates, featuring base supports and steel-strap reinforcement; crates are clearly marked with lifting points and moisture-proof labels. Large items may be shipped in flat-pack configuration to reduce volume and minimize ocean freight costs.
- Lead Time: 10–18 business days for standard sizes; 20–28 business days for custom-sized (extra-large) units, items with specific hardness requirements, or those featuring imperial-grid patterns.
- Customizable table dimensions (non-standard sizes available)
- Material options: Q355, HT300, or P20 mold steel
- Customizable nitriding hardness; imperial-unit grid markings
- Pre-configured cutouts for scrap/part discharge and clearance gaps for robotic access
