Nitrided D28 and D16 System 3D Welding Table is a high-precision modular tooling system specifically designed for welding metal components such as gantries, brackets, cabinets, and handrails. This welding workbench adopts advanced 3D positioning technology, which can provide a highly flexible and accurate positioning solution for welding operations.
Main features
Nitrided surface:
The workbench surface undergoes special nitriding treatment, significantly improving wear resistance and corrosion resistance.
This extends the service life of the workbench.
It ensures that the positioning accuracy remains stable over the long term.
Dual - specification system:
D28 system: With a 28mm hole diameter standard, it is suitable for heavy - duty welding applications.
D16 system: With a 16mm hole diameter standard, it is suitable for precision welding and small workpieces.
3D modular design:
It can be flexibly positioned in the X, Y, and Z dimensions.
Precise positioning of complex workpieces can be achieved by combining different modules.
Multi - functional application:
It is particularly suitable for welding structural parts such as gantry, brackets, cabinets, and handrails.
It can be used for welding positioning of various metal materials.
