1500*1000 D28/D16 China-Made Nitriding 3D Welding Worktable is a modular and high-precision welding and assembly platform, specifically designed for the welding of small and medium-sized workpieces, fixture positioning, and precision inspection. This workbench is made of high-quality cast iron or structural steel and undergoes nitriding heat treatment, featuring ultra-high hardness, wear resistance, and anti-deformation properties. It is widely used in fields such as machining, automotive parts manufacturing, mold assembly, and automated welding.
Core Features
(1) Dual-aperture (D28/D16) Precision Hole System
D28 Large Hole: Used for the installation of heavy-duty fixtures and positioning pins, with strong load-bearing capacity.
D16 Small Hole: Used for precise fine-tuning and fixing small fixtures, improving flexibility.
Matrix Arrangement: Equally spaced at 100mm intervals (50mm high-density holes are optional), ensuring high-precision positioning.
(2) Nitriding Heat Treatment Process
Ultra-high hardness (HV900 - 1200), with wear resistance far exceeding that of ordinary welded platforms.
Corrosion Resistance: The nitrided layer effectively prevents the erosion of welding slag and coolant.
Anti-deformation: It can still maintain high flatness after long-term use, suitable for precision welding.
(3) Modular Design
Compatible with quick fixtures, positioning blocks, and hydraulic clamping systems.
Scalable and spliceable, multiple units can be combined to form a larger working area.
Supports robotic automated welding and is adaptable to mainstream fixture systems (such as DEMMELER, Rexroth, etc.).
(4) High Rigidity and Stability
HT250 Cast Iron: Good shock absorption, reducing welding deformation.
Q355 Steel Structure: Welded and reinforced type, suitable for heavy-duty working conditions.

Usage and Maintenance Guide
1.Installation Requirements
Place it on a flat surface or a reinforced support to avoid distortion.
Use a special positioning pin to install the fixture. Do not directly hammer the tabletop.
2.Daily Maintenance
Regularly blow the hole system with compressed air to prevent welding slag from clogging.
Residual spatter on the surface can be cleaned with an anti-rust cleaning agent.
When not in use for a long time, apply anti-rust oil and cover it with a dust-proof cloth.
3.Precautions
Avoid local overloading (single-point force ≤ 3 tons).
Do not directly apply flame cutting to the tabletop to prevent damage to the nitrided layer.

Selection and Usage Suggestions
1. Selection Principles
Precision First: Choose D16 (such as for the assembly of laser - cut parts).
Heavy - load Requirements: Choose D28 (such as for the welding of hydraulic press frames).
2. Maintenance Key Points
Regularly clean the oil stains inside the holes with alcohol to avoid fixture loosening.
For heavy workpieces, the load should be evenly distributed to prevent local deformation.
