Frequently Asked Questions
We understand precision in manufacturing matters, and so does comprehensive clarity. Here are the considerable answers to enquiries we receive from our prospects and clientele.
01. What is the precision and accuracy tolerance of your granite surface plates?
Industrial surface plates for QA are classified by flatness tolerance grades defined in standards like IS 7327. These tolerance levels ensure that the granite surface plates provide a reliable reference surface for – dimensional inspection and calibration.
02. How frequently should granite surface plates be calibrated?
The ideal calibration interval for granite surface plates depends on several factors—including usage intensity, environmental conditions, and the level of precision required. For high-accuracy plates such as Grade 00 and Grade 0 (as per IS 7327 and DIN 876), more frequent calibration is recommended to maintain their certified flatness and repeatability.
03. Can I get a custom size or shape of granite surface plates?
Yes, you can absolutely get custom sizes and shapes of granite surface plate with levelling jacks. Manufacturers like Graph Datum offer extensive customization options, comprising customization capabilities.
04. Do you ship granite surface plates globally?
Yes, laboratory-grade granite surface plates can be shipped globally. Manufacturers like Graph Datum offer global shipping for both standard and custom flatness calibrated surface plates.
