Granite/marble rulers are mainly used in the following areas:

• Measuring straightness: In mechanical processing and precision measurement, it is used to detect the straightness error of machine tool worktable, guide rail, workpiece, etc. It is an important measuring tool to determine whether the measured object meets the straightness requirements.

Calibration equipment: It can be used as a reference tool to adjust and calibrate some equipment that requires straightness calibration, such as calibrating the guide rails of grinding machines, milling machines, and other machine tools, to ensure the accuracy and stability of the equipment.

Installation and debugging: During the equipment installation process, it is used to check the levelness and straightness of the installation surface, ensure the horizontal and vertical accuracy of the equipment installation, and enable the equipment to operate normally.

Quality inspection: In the product quality inspection process, the straightness of components is measured and evaluated to ensure that product quality meets standard requirements. It is commonly used in industries such as automotive manufacturing, aerospace, and mold manufacturing that require high precision of components.

Marble square ruler is mainly used in the following aspects:

1. Detect verticality and right angle accuracy

Used to detect the perpendicularity error between components of machine tools and mechanical equipment (such as columns and workbenches, guide rails and spindles), ensuring the right angle accuracy of equipment assembly and operation.

In construction or decoration, it is possible to detect whether the walls, door and window frames, etc. are vertical and provide a right angle reference.

2. Precision machining benchmark

As a right angle benchmark for marking tools, perform right angle positioning before precision part machining to ensure the accuracy of subsequent drilling, milling, and other processes.

Used to calibrate the coordinate system of CNC machine tools and machining centers, ensuring the X/Y axis perpendicularity of the coordinate system.

3. Calibration of Optics and Precision Instruments

Provide a right angle reference for adjusting the optical path of optical instruments such as microscopes and telescopes, ensuring the orthogonality of optical components.

Calibrate the optical path direction of the laser equipment to ensure that the laser beam is perpendicular to the workbench.

4. Quality inspection and quality control

Perform tolerance testing on the right angled surfaces of precision components such as gears and bearing seats to determine if they meet design requirements.

In the automotive and aerospace fields, it is used to detect the right angle accuracy of key components such as engine cylinder blocks and wing structures.

5. Installation and commissioning

During the installation of precision equipment, assist in adjusting the right angle positioning of the equipment base and bracket to ensure smooth operation of the equipment.

Used for horizontal and vertical calibration of laboratory workbenches and optical platforms, providing a stable experimental environment.
