基本信息
This granite surface box is a professional measuring fixture designed for detecting squareness, parallelism and height difference of workpieces, widely used in mechanical processing and precision measurement scenarios. Made of natural high-density granite, it has excellent dimensional stability and wear resistance, which can maintain long-term measurement accuracy without regular calibration for a long time. Compared with traditional steel or cast iron surface boxes, it has no magnetic adsorption, will not interfere with non-ferrous metal or electronic workpiece testing, and has better corrosion resistance to workshop oil stains and dust. It is suitable for small and medium-sized workpiece positioning and precision detection in machining workshops.
