Stone Made Precision Straight Ruler

Stone Made Precision Straight Ruler Characteristics

High Precision:Granite has gone through long-term natural aging,with a uniform organizational structure,a very small linear expansion coefficient,and the internal stress has completely disappeared,so it hardly deforms,which can ensure high-precision measurement.

Good Stability:It has good rigidity,high hardness,and strong wear-resistance.It is not easily affected by environmental factors such as temperature and humidity,and can maintain stable performance during long-term use.

Excellent Corrosion-Resistance:It is not afraid of acid and alkali erosion,does not rust,does not need to be oiled,and is not easy to adhere to dust.It is easy to maintain and has a long service life.

Other Advantages:It will not be magnetized,and when measuring,it can move smoothly without a sense of stagnation.It is not affected by humidity,and the plane stability is good.

Specifications and Accuracy

Common Specifications:There are various specifications such as 400mm×60mm×35mm,630mm×100mm×50mm,1000mm×160mm×50mm,1600mm×250mm×80mm,and 2000mm×300mm×100mm.

Accuracy Levels:Usually,it can reach an accuracy of higher than 0.001mm,and different accuracy levels such as grade 00 and grade 0 are available to meet different measurement requirements.The straightness tolerance,parallelism tolerance of the upper and lower working surfaces,and perpendicularity of the working surface to the sides of rulers of different specifications all meet the corresponding standards.

Applications

In the Machinery Manufacturing Industry:It is used for the assembly,installation,and inspection of machine tools,and for the detection of the straightness,parallelism,and perpendicularity of guides and precision components,which helps to ensure the machining accuracy of mechanical parts.

In the Field of Precision Instruments:It is an important tool for the manufacturing and calibration of precision instruments and meters,ensuring the accuracy and reliability of the installation and measurement of instruments and meters.

In Scientific Research Institutions:It is used in some scientific research experiments that require high-precision measurement to provide a precise measurement reference.

Usage and Maintenance

Usage Methods:When in use,the stone-made precision straight ruler should be placed stably on the surface of the object to be measured,and the measurement surface should be kept clean and free of impurities.Align the ruler with the measured part,and then observe or use other measuring tools in combination to obtain measurement data.

Maintenance Points:Avoid collision and dropping to prevent damage to the ruler.After use,wipe the surface of the ruler clean with a soft cloth and keep it in a dry and ventilated place.Regularly send it to a professional metrology department for calibration to ensure its measurement accuracy.
