Welding Cast Iron Table and Fixture 3D CNC Machining Industry is a cast iron 3D welding workbench designed specifically for high-precision welding and CNC machining. It adopts the D28 standard hole system, with dimensions of 1500mm×2000mm×200mm (length×width×height), and is suitable for fields such as industrial manufacturing, mold processing, and welding fixture positioning.
This workbench is made of high-strength cast iron, undergoes precision machining and heat treatment, and has excellent stability, shock resistance, and wear resistance. It is particularly suitable for applications such as 3D welding, CNC machining, assembly, and inspection.
Core Features
1. Materials and Structure
High-strength cast iron material: It has excellent seismic resistance and rigidity, reducing machining vibration and improving stability.
Precision machining: The workbench surface is ground and scraped to ensure high flatness (usually ≤0.02mm/m).
Nitriding treatment or surface hardening (optional): It improves wear resistance and corrosion resistance, extending the service life.
2. D28 Standard Hole System
28mm positioning holes: The standardized D28 system is adopted (the hole pitch is usually 50mm or 100mm), which is compatible with various fixtures.
Modular design: It can be equipped with accessories such as 3D welding fixtures, positioning pins, and quick clamps to achieve multi-angle positioning.
High repeat positioning accuracy (±0.05mm), suitable for precision welding and CNC machining.
3. Size Specifications (1500×2000×200mm)
Length 1500mm × Width 2000mm: Suitable for welding and processing of medium and large workpieces.
Thickness 200mm: It provides sufficient rigidity and stability to prevent deformation.
Customizable sizes (such as 1000×1000, 2000×3000, etc.).
