High Hardness Nitrided Cast Iron 3D Welding Table is a professional - grade precision welding and assembly work platform, specifically designed for the high - precision manufacturing field. Its size is 1000mm×2000mm, and the hole pitch is D28 (with a 28mm spacing).
Main features
High-hardness nitrided surface:
After special nitriding treatment, the surface hardness can reach HRC50 - 55.
Significantly improve wear resistance and corrosion resistance.
Prolong the service life of the worktable.
High-quality cast iron material:
Manufactured with high-strength cast iron.
It has excellent stability and shock absorption performance.
The thermal deformation coefficient is low, ensuring long-term use accuracy.
D28 hole system:
28mm standard hole pitch design.
Complies with international common fixture system standards.
Compatible with most brand fixtures and accessories.
Precision machining:
The flatness of the worktable is usually controlled within 0.05mm/m².
The hole position accuracy is high, and the repeat positioning accuracy is excellent.

Application fields of
High Hardness Nitrided Cast Iron 3D Welding Table
√Precision welding: Welding of precision components in industries such as automobiles, aerospace, and rail transit.
√Tooling fixtures: Used as a basic platform for the installation of various tooling fixtures.
√Inspection and measurement: Used as an inspection reference platform.
√Mechanical assembly: Precision assembly of large mechanical equipment.
√Mold manufacturing: Mold processing and inspection.

• Modular design: Install fixtures, locating pins, bolts and other tooling quickly through the D28 hole system to adapt to the processing of various workpieces.
• Flexible application:
High Hardness Nitrided Cast Iron 3D Welding Table can be equipped with extended accessories (such as angle adjustment modules, T-slot guides) to achieve multiple functions (welding, inspection, assembly, etc.).
• High precision: The flatness of the tabletop is usually ≤0.1mm/m², and the hole position tolerance is ±0.05mm to ensure processing consistency.
• High temperature resistance: Q355 steel can withstand welding spatter, and the surface can be galvanized or sprayed with an anti-rust layer to extend its service life.
