Granite Straight Edge Leveling Ruler

A granite straight edge leveling ruler is a high-precision measuring tool used for checking straightness,flatness,and leveling.Here is a detailed introduction:

Characteristics

High Precision:Usually available in precision grades such as 00,it can provide very high-accuracy measurement results.For example,a 400x60x25mm granite straight edge leveling ruler may have an accuracy within±0.001mm.

Good Stability:Made of granite,which has a low coefficient of thermal expansion,it is less affected by temperature changes,ensuring stable performance and accurate measurement results in different environments.It also has high resistance to wear,corrosion,and mechanical deformation,with a long service life.

Excellent Flatness and Straightness:The working surfaces of the ruler are extremely flat and straight.After precise grinding and processing,the flatness and straightness errors are very small,which can meet the needs of high-precision measurement.

Applications

Machine Tool Installation and Inspection:In the installation and adjustment of machine tools,it is used to check the straightness and flatness of the guide rails and the installation level of the machine tool bed,ensuring the accuracy and stability of the machine tool during operation.For example,when installing a CNC machine tool,the granite straight edge leveling ruler is used to check whether the guide rails are installed straight and level to ensure the accuracy of the machine tool's movement.

Precision Manufacturing and Inspection:In the fields of precision machinery manufacturing,electronics manufacturing,etc.,it is used to measure and inspect the straightness and flatness of precision parts,ensuring that the parts meet the design requirements.For example,in the manufacturing of aerospace-grade parts,the granite straight edge leveling ruler is used to check the straightness and flatness of the parts to ensure their high-quality and high-precision requirements.

Laboratory and Metrology:In laboratories and metrology institutions,it is used as a standard measuring tool for calibrating and verifying other measuring instruments,such as straight rulers,calipers,etc.,to ensure the accuracy and reliability of the measurement results of these instruments.
