00 Grade Granite Triangular Ruler

The 00 Grade Granite Triangular Ruler is a high-precision measuring tool.The following is its related introduction:

characteristic

High precision:Level 00 represents an extremely high level of precision.Its flatness,straightness,and angle tolerances are all controlled within a very small range.For example,the flatness error usually does not exceed±0.5μm per 25mm edge length,and the angle error can be controlled within±2",which can meet the high-precision measurement requirements.

Excellent Material:Made of granite material,it has many advantages.Granite,after long-term natural aging,has completely eliminated internal stress,excellent stability,and is not easily deformed.At the same time,it has the characteristics of high hardness and strong wear resistance,which can maintain the accuracy of measuring tools for a long time.It also has good corrosion resistance and anti magnetic performance,and is not affected by external environmental factors.

Good surface quality:The working surface has undergone precision grinding and polishing treatment,with a small surface roughness value,usually reaching Ra0.05-Ra0.1μm,smooth and flat,which can effectively reduce frictional resistance during measurement,improve measurement accuracy and repeatability.

purpose

Precision measurement:used in industries such as mechanical manufacturing,aerospace,and automotive manufacturing to measure and inspect geometric parameters such as angles,straightness,and flatness of high-precision parts.For example,in the machining process of engine cylinder blocks,precision molds,and other parts,a 00 grade granite triangle ruler can be used to check the accuracy of their angles and planes,ensuring that the parts meet the design requirements.

Calibration and verification:It can be used as a standard measuring tool for calibrating and verifying other measuring tools,such as angle gauges,square rulers,etc.In metrology and testing institutions,precision calibration and error evaluation of other measuring tools are carried out by comparing and measuring with a 00 grade granite triangular ruler to ensure the accuracy and consistency of the measurement system.

Assembly positioning:used in the assembly process of precision equipment to determine the angle and position relationship between parts,ensuring assembly accuracy.For example,in the assembly of optical instruments,electronic devices,etc.,a 00 grade granite triangle ruler is used to ensure the verticality and angular accuracy of component installation,in order to ensure the performance and quality of the equipment.

Maintenance

Cleaning:Use a clean and soft cloth to regularly wipe the surface of the triangular ruler to remove dust,oil stains,and other impurities.Avoid using rough or corrosive cleaning agents to prevent damage to surface accuracy.

Storage:It should be stored in a dry and constant temperature environment,avoiding moisture,heat or cold,and preventing deformation of the triangular ruler due to changes in temperature and humidity.It is best to place it in a dedicated measuring box and place a desiccant inside the box to keep it dry.

Handle with care:The 00 Grade Granite Triangular Ruler is a high-precision measuring tool,and special care should be taken during use and handling to avoid collisions,drops,or severe vibrations that may damage its accuracy.

Regular calibration:In order to ensure measurement accuracy,it is recommended to regularly send the 00 grade granite triangle ruler to a professional metrology institution for calibration.The calibration cycle generally depends on the frequency of use and actual situation,usually one or six months.
