Marble ruler is a high-precision measuring tool made of natural marble (recrystallized limestone), with a vertical and parallel frame combination structure. It is suitable for high-precision mechanical and instrument inspection, as well as checking the non perpendicularity between machine tools. It can also be used to detect the straightness, parallelism, and perpendicularity of components.
main purpose
Checking the verticality of the machine tool: Check whether the spindle, guide rail and other components of the machine tool are vertical, for example, spindle verticality detection is a key link in mechanical processing.
Measuring parallelism: By using a box type combination to detect the parallelism between components, the machining accuracy is ensured.
Industrial Inspection Standards: Suitable for the inspection of instruments, precision tools, and high-precision measurement scenarios.
Material and physical properties: The main components are feldspar, plagioclase, olivine, biotite, etc. The density is about 2970-3070kg/m ³, the compressive strength can reach 2500-2600kg/cm ², the elastic coefficient is 1.27-1.47 × 10 ⁶ N/mm ², the water absorption rate is 0.13%, and the Shore hardness exceeds HS70. These characteristics make it have the advantages of dense organizational structure, smooth and wear-resistant surface, stable material that is not easily deformed, acid and alkali resistance, corrosion resistance, and demagnetization resistance.
Production process: Natural marble is used as the raw material, which has undergone years of natural aging, with uniform texture and strong stability.
Application areas: Widely used in machine tool maintenance, precision part inspection, optical instrument calibration and other fields, such as checking the perpendicularity of the X-axis and Y-axis coordinates of machine tools, providing reliable references for high-precision work.
Usage and maintenance: Handle with care to avoid collision and scratches during use. Use in a constant temperature, dust-free, and vibration free environment, and clean regularly to maintain accuracy and good usability.
