基本信息
This granite inspection surface plate is a large-scale high-precision measuring platform, mainly used for flatness detection, workpiece positioning and precision processing benchmark setting of large and medium-sized workpieces. Made of natural Jinan blue granite, it has excellent dimensional stability, wear resistance and corrosion resistance, which can maintain long-term measurement accuracy without frequent calibration. Compared with traditional cast iron surface plates, it has no magnetic adsorption, will not adsorb iron filings and other impurities, and has better corrosion resistance to workshop oil stains and dust. It is suitable for large-scale precision processing and testing scenarios in aerospace, automobile manufacturing and other industries.
