In-depth Details
- The standard height of the side panel is 200 mm; the sides of the D28 welding table feature a full grid of D28 holes (spaced at 100×100 mm) extending from top to bottom, rather than just a few sparse rows.
- The perpendicularity tolerance between the top surface and the four side panels is 0.1 mm / 200 mm. This specification directly determines the accuracy of 90° right-angle setups for side-mounted workpieces.
- "Five-sided hole configuration" is not merely a matter of drilling holes in the sides; the top surface and all four sides undergo unified CNC machining based on a single reference point to ensure alignment across the entire hole pattern.
- Side holes allow for the direct mounting of right-angle blocks, side clamps, and vertical extension modules. Workpieces can be mounted vertically against the side panel without the need for riser blocks, thereby eliminating cumulative errors.
Transportation and Installation
- D28 welding tables are very heavy; for instance, a 2000×1000mm unit weighs approximately 700-900 kg. Forklifts or overhead cranes are required for lifting; lifting holes are a standard feature on the tabletop.
- Export/Sea Freight: Packed in fumigation-free solid wood crates with internal foam protection for the working surface to prevent impact damage during transit.
- Installation Sequence: Position tabletop → Lift into place → Install legs → Rough leveling → Fully tighten fasteners → Verify flatness with a laser level → Install fixtures.
- Floor Requirements: For heavy-duty applications, a concrete floor thickness of ≥150 mm is recommended. For heavy-duty robotic welding stations, securing the unit to the floor with chemical anchors is recommended.
FAQ
Q: Is this D28 5‑sided welding table compatible with other brand D28 fixtures?
A: Yes, it follows DIN D28 hole‑system standard, compatible with most mainstream D28 modular fixture sets on the market.
Q: Can you offer OEM / ODM service?
A: Yes. Custom dimensions, special marking/logo are available. Minimum order applies for OEM service.
Q: What is your lead time for 5‑sided D28 welding tables?
A: For Q355 steel version: 7‑15 working days. For HT300 cast iron version: 20‑35 working days. Custom large sizes over 3000×2000mm will take extra production time.
Q: What is your payment term?
A: 30% deposit upon PI confirmation, 70% balance before shipment. Other negotiable terms available for long‑term bulk orders.
Q: Do you provide inspection report before shipment?
A: Yes. We supply dimension report, flatness & perpendicularity test record. Third‑party inspection is acceptable upon buyer's request.
