28mm Hole 3D Welding table 2400 x1200 x200mm Nitrided Finish 25mm Table Plate

28mm Hole 3D Welding table 2400 x1200 x200mm Nitrided Finish 25mm Table Plate

The 28mm Hole 3D Welding Table (2400×1200×200mm, Nitrided Finish, 25mm Table Plate) is a high-precision, heavy-duty, and highly wear-resistant 3D flexible welding workbench. Its core parameters are designed to meet the precise welding needs of medium to large workpieces. The following is a detailed breakdown and product description:

1. Tabletop Material
The main body is made of high-strength cast iron HT300 (some high-end models use Q355B alloy steel plate). HT300 cast iron has excellent vibration resistance, thermal conductivity, and dimensional stability. It undergoes a dual treatment of artificial aging and natural aging to completely eliminate internal casting stress, ensuring that the flatness of the tabletop does not change significantly during long-term use.

2. Hole System Structure
In addition to the φ28mm main positioning holes, the tabletop also features φ16mm auxiliary positioning holes (on some models). The hole walls are precisely reamed and heat-treated, with a perpendicularity error of ≤0.02mm/100mm, ensuring precise positioning and quick locking of tooling accessories.

3. Support Structure
For the 2400×1200mm large tabletop, four sets of heavy-duty support legs are standard (upgradable to six sets). The leg assemblies are welded from thick-walled square tubes with built-in reinforcing ribs. Each leg has a load capacity of ≥3T, and the overall workbench can support 12–18T, meeting the needs for placing heavy workpieces.

1.Ultra-high precision: Tabletop flatness error ≤ 0.05mm/1000mm, overall flatness ≤ 0.2mm/2400mm, meeting the precision requirements for precision welding and assembly;

2.Ultra-long lifespan: The nitrided tabletop has 3-5 times the wear resistance of ordinary hardened tabletops, maintaining hole system accuracy and surface flatness for a long time, reducing maintenance costs;

3.Ultra-strong load-bearing capacity: 25mm thick tabletop + heavy-duty support legs can withstand the static load of heavy workpieces and thermal deformation stress during the welding process, without the risk of tabletop collapse;

4.Flexible compatibility: φ28mm standard hole system is compatible with mainstream flexible tooling accessories worldwide, supporting rapid fixture replacement and multi-station combinations, meeting the needs of multi-variety, 5.small-batch production.

1.Medium to large-scale steel structure welding: such as crane arms, building steel structures, bridge components, etc.;

2.Special equipment enclosure assembly: such as engineering machinery cabs, mining equipment housings, large control cabinets, etc.;

3.Rail transit component manufacturing: such as subway car frames, high-speed rail seat brackets, rail connectors, etc.;

4.Heavy machinery parts processing: such as large gearboxes, hydraulic supports, excavator chassis, etc.

1. Compliance Guarantee: All wooden packaging strictly conforms to IPPC/ISPM 15 standards, undergoing fumigation/heat treatment and marked with the HT symbol, ensuring smooth customs clearance worldwide and preventing delays caused by packaging compliance issues.

2. Precision and Protection Guarantee: A rigorous component protection process is implemented, with nitrided surfaces, 28mm positioning holes, and metal parts treated for rust prevention, scratch resistance, and deformation prevention, ensuring that the product's precision and surface condition remain consistent with factory specifications after transportation, free from dents, corrosion, or precision deviations.

3. Load-Bearing and Safety Guarantee: The overall packaging has a load capacity of ≥3T, suitable for ocean shipping stacking and mechanized handling. Forklift holes and lifting lugs are designed to meet safety standards, preventing packaging damage and product displacement during loading, unloading, and transportation.

4. Documentation and Labeling Guarantee: A complete set of English documents (packing list, instruction manual, certificate of conformity, etc.) is included with each package. The outer packaging is clearly and accurately labeled, ensuring customers can quickly verify and install the product upon receipt.

5. Timeliness Guarantee: A strict packaging cycle of 1-2 days per set is maintained, ensuring on-time delivery and preventing delays in overall export schedules.
