The ART.555 / ART.557 Cast Iron Surface Plate is a high-precision reference base designed for dimensional inspection, layout, and tooling setup in metrology labs and industrial environments. Manufactured from G25 perlitic cast iron, these plates are naturally seasoned and stress-relieved to ensure long-term stability and accuracy.
Key features
- Material: G25 perlitic cast iron, free from blowholes or structural flaws
- Natural seasoning for dimensional stability
- DIN 876/1 or DIN 876/3 flatness tolerance (depending on model)
- Closely scraped or ground surface for high-precision applications
- Ribbed underside for optimal load distribution and rigidity
- Square, machined edges for easy alignment and setup
Model Comparison: ART.555 vs ART.557
Both the ART.555 and ART.557 cast iron surface plates are manufactured to the highest standards, but they are designed for slightly different applications:
| Feature | ART.555 | Art.557 |
|---|---|---|
| Surface Finish | Scraped finish | Ground finish |
| Flatness Grade | DIN 876/3 (Standard) | DIN 876/1 (High Precision) |
| Use Case | General inspection, layout work | High-precision measurement, calibration |
| Price Point | More economical | Premium option |
- Choose ART.555 if you need a reliable, cost-effective solution for general workshop or inspection tasks.
- Choose ART.557 for high-accuracy applications where surface flatness and finish are critical.
