• Materials:
Tabletop: High-strength cast iron (HT250/HT300) or pre-hardened alloy steel (such as S355JR), with strong anti-deformation ability.
Surface Treatment: Precision grinding (roughness Ra≤1.6μm), and options of galvanizing, blackening, or anti-rust spraying are available.
• Load-bearing Capacity: The static load is usually ≥ 5 tons, and the dynamic load (welding vibration) is ≥ 2 tons.

Typical application scenarios
• Industry:
Heavy machinery welding, rail transit component assembly, shipbuilding, energy equipment (such as wind power towers).
• Processing types:
Multi - position welding of large - scale structural components, precise component alignment, inspection fixture platforms.
• Advantageous cases:
When welding trusses, multiple support points are quickly fixed through the D28 hole system to avoid thermal deformation.
Frequently Asked Questions
• Q: Can the D28 hole system be compatible with other standard fixtures?
A: It can be adapted through an adapter plate (such as D28 to D16), but the loss of rigidity needs to be considered.
• Q: Is foundation fixing required?
A: For processing heavy workpieces, fixing (chemical anchor bolts or embedded steel plates) is recommended. For light - duty use, shock - absorbing feet can be equipped.
• Modular 3D Clamping System:
Achieve 360° multi - angle positioning through the D28 hole array, supporting vertical, horizontal, and inclined clamping.
Compatible with standard fixtures (such as clamps, locating pins, angle adjustment blocks).
• High - Rigidity Structure:
Box - type welded base or rib - reinforced design to reduce vibration and deformation, with flatness ≤ 0.1mm/m².
.
-
• Extended Flexibility:
Multiple units can be spliced (connected by locating pins or bolts), and customized T - slots or vacuum adsorption functions are supported.
• Quick Changeover:
Use quick - release handles or hydraulic fixtures to shorten the tooling adjustment time (typical changeover time < 5 minutes).
