3D welding tables accuracy level

The accuracy grades of 3D welding tables are divided into Grade 00, Grade 0, Grade 1, Grade 2, and Grade 3 according to national standards. The commonly used grades in the industry are Grade 0, Grade 1, and Grade 2.

1. Platform Accuracy (Flatness)

In accordance with national standard measurement regulations, the accuracy grade corresponds to the flatness tolerance (unit: μm).

2. Key Precision Indicators for 3D Flexible Welding Tables (General Industry Standard)

Flatness: 0.05mm/m (Grade 0)

Hole spacing: 100mm (Series 28) / 50mm (Series 16), tolerance ±0.05mm

Repeat positioning accuracy: ≤ ±0.05mm

Overall system accuracy: ≤ ±0.1mm

3. Selection Recommendations

Grade 0: Precision inspection, high-precision welding (e.g., automotive, aerospace)

Grade 1: General precision welding and assembly

Grade 2: Conventional welding, general tooling
