Granite Master Square
Crafted from natural granite, it is highly stable, wear-resistant, and unaffected by temperature and humidity, making it a reliable tool for core geometric tolerance inspection:
1. Measuring flatness: Quickly verify the flatness of machine tool tables and precision platforms to avoid assembly deviations.
2. Measuring perpendicularity: Relying on a precise 90° right angle, it can inspect the vertical relationship of workpieces and equipment components to ensure structural orthogonality.
3. Measuring straightness: When paired with a dial indicator, it can check the straightness of guide rails and shaft parts, enhancing operational stability.
4. Measuring parallelism: It can assess the parallel error of precision fixtures and mold templates to ensure processing consistency.

Natural granite construction ensures exceptional stability, wear resistance, and immunity to temperature/humidity changes—making it a trusted tool for core geometric tolerance inspection:
1. Flatness: Verify machine tables and precision platforms in seconds—prevent assembly errors.
2. Perpendicularity: Use its precise 90° edge to confirm vertical alignment—ensure structural orthogonality.
3. Straightness: Pair with a dial indicator to check guide rails or shafts—boost motion accuracy.
4. Parallelism: Assess fixtures and mold plates—guarantee consistent machining.
Long-term accuracy. Zero drift. The precision guardian for aerospace, molds, and advanced equipment.
We use various techniques during this process:
● Optical measurements with autocollimators
● Laser interferometers and laser trackers
● Electronic inclination levels (precision spirit levels)
1. Documents together with products: Inspection reports + Calibration reports(measuring devices) + Quality Certificate + Invoice + Packing List + Contract + Bill of Lading(or AWB).
2. Special Export Plywood Case: Export fumigation-free wooden box.
