- Abrasion resistant and non-wedging surface
- Wrap-resistant construction for long-term stability
- Easy to clean and maintain
- Excellent distribution of hard quartz for smooth, long-wearing surface
Precision Standards & Certifications
Our granite surface plates meet or exceed Federal Specifications DIN/876. Final inspection and calibration of every surface plate is accomplished using Auto-Collimeter technology.
Repeatability Specifications
- Grade "B" Toolroom: ± 100 Millionths
- Grade "A" Inspection: ± 50 Millionths
Flatness Tolerance Standards (JB/T 7975-1999)
Our granite surface plates reference advanced international standards with flatness tolerance calculated as:
- Grade 000 = 1×(1+d/1000)/μm
- Grade 00 = 2×(1+d/1000)/μm
- Grade 0 = 4×(1+d/1000)/μm
- Grade 1 = 8×(1+d/1000)/μm
(d represents the length of the diagonal)
