Granite right angle gauge (also known as granite right angle ruler) is a precision measuring tool made of natural granite as the substrate, mainly used for industrial production and precision measurement in laboratories. Its core functions include detecting the straightness, flatness, and relative positional accuracy of workpieces, suitable for equipment installation, machine tool guide rail calibration, and other scenarios.
Granite square ruler is a precision measuring tool made of natural granite as the base material, with characteristics such as low linear expansion coefficient, disappearance of internal stress, and strong rigidity. This measuring tool can maintain measurement accuracy from level 0 to level 2 at room temperature, and is suitable for industrial applications such as workpiece flatness verification and equipment installation positioning
Mainly used for geometric accuracy inspection of workpieces, including measurement of flatness, perpendicularity, and straightness. Its main material is granite, composed of quartz, plagioclase, a small amount of olivine, biotite, and trace amounts of magnetite, presenting a deep black color. After many years of natural formation and evolution, granite square rulers have gained uniform texture and good stability, and can maintain high measurement accuracy even under high load conditions.
This ruler has a well-designed structure and uses coding technology to make the measurement process more accurate. It has been widely used in industrial production and laboratory environments, and is a key tool for ensuring product quality and accuracy in scientific research experiments. Whether it is large-scale production lines or fine scientific research work, granite square rulers provide reliable measurement guarantees for workers in various fields with their high precision and durability.
main purpose
Workpiece inspection: Detecting the perpendicularity error and relative positional accuracy of mechanical components, such as checking the flatness and straightness of machine tool workbenches and guide rails.
Equipment installation positioning: Determine the reference plane position during the installation of auxiliary equipment to ensure the verticality and accuracy requirements of mechanical components.
Industrial measurement: used for marking operations in industrial production, as well as calibration and acceptance of workpiece dimensions in precision machining.
