Professional Q&A: Surface Plate & Cast Iron Angle Plate Applications

1. What is the best material for a surface plate in industrial applications?

While granite and steel have their roles, cast iron surface plate is often preferred in heavy industry due to its excellent reparability, vibration-damping properties, and resistance to temperature changes.

2. How do you specify the flatness grade of a surface plate?

Flatness grades (e.g., Grade 0, Grade 1, Grade 2 per DIN 876) are defined by allowable deviation per square meter. For high-precision labs, Grade 0 (≤0.016mm/m²) is recommended.

3. What is the normal hardness range for cast iron surface plate?

Industry standards, such as ISO 1863-2019, specify a Brinell Hardness (HB) of 170–240 for cast iron surface plates, balancing wear resistance with machinability.

4. Are there international standards for surface plate production?

Yes. Main standards include DIN 876 (flatness), DIN 875 (squareness), ISO 8512, GB/T 22095, and ASME B89.3.7M. Adherence ensures universal compatibility and calibration traceability.

5. Why is squareness critical for angle plates?

Squareness guarantees that machined or inspected parts conform accurately to geometric tolerances, directly impacting final product quality in precision manufacturing.

6. How often should a surface plate be recalibrated?

For critical measurements, periodic recalibration (every 12-24 months, or as demanded by frequency of use/abrasion) is essential. Some applications require on-site inspection using electronic levelers as recommended by the NIST Metrology Guidelines.

7. What factors affect the cast iron surface plate price?

Price is influenced by size, flatness grade, weight, customization (T-slots, V-grooves), and certification/traceability requirements. Cheap surface plate models may offer basic accuracy, but industrial-grade plates invest more in precision and durability.
