The NG-AutoPol system integrates multiple advanced functions that make it exceptionally efficient for preparing tensile and fatigue testing specimens. Here are some of its key highlights:
- Automatic Longitudinal Polishing: Provides consistent, repeatable surface results with controlled single-contact polishing.
- Customizable Parameters: Adjust rotation, force, speed, and polishing length directly from the touchscreen interface.
- Multi-Grit Sandpaper Switching: Automatically transitions between up to four sandpaper types within one polishing cycle.
- Integrated Cleaning System: Keeps the sandpaper clean for longer service life and uniform performance.
- Stable Mechanical Design: Maintains polishing accuracy and uniform pressure across all sample types.
- Process Memory Function: Saves polishing configurations for identical repeat runs and standardized workflows.
- Compact, Low-Maintenance Setup: Space-efficient design ideal for busy laboratories with limited floor area.
- Low-Stress Surface Finishing: Uses precise pressure control and linear motion to minimize residual stress and preserve specimen integrity.
- Multi-Geometry Compatibility: Quickly adapts to cylindrical, flat, small, and large specimens with interchangeable fixtures.
- NADCAP Compliance Option: Available in NADCAP-ready configuration for certified aerospace and high-precision testing environments.

Global Testing Standards Compliance
To operate on a global scale, the NG-AutoPol system supports multiple industry standards. This means that your lab results are internationally recognized and comparable across testing facilities in North America, Europe, Asia, and beyond. Below are the standards that NG-AutoPol complies with:
- ASTM E466 – Force-Controlled Constant Amplitude Axial Fatigue
Defines the procedure for fatigue testing of metallic samples under a constant axial load amplitude, where strains remain mostly elastic. It is used to assess fatigue life under repeat loading. - ASTM E606 – Strain-Controlled Fatigue Testing
Covers fatigue tests where the strain (rather than the stress) is controlled across cycles. It is used to study low-cycle fatigue and the plastic deformation that occurs during repeated loading. - EN 6072 – Metallic Materials — Constant Amplitude Fatigue Testing (S-N method)
European standard equivalent for S-N fatigue data under constant amplitude loading, aligning specimen geometry and testing methods across labs. - NADCAP (Materials Testing Accreditation)
An accreditation program used in aerospace and related industries to validate that testing, preparation, and inspection processes meet rigorous quality and traceability standards. NG-AutoPol can be used in a NADCAP-ready configuration.
