Marble square ruler

The main mineral components of a marble square ruler are runaways, plagioclase, a small amount of olivine, biotite, and trace amounts of magnetite. It has a black color, a structural code, uniform texture, good stability, and high strength, and can be maintained under heavy loads. Suitable for industrial production and laboratory measurement work.

Marble ruler is used for measuring the flatness, verticality, and straightness of workpieces.

Characteristics and advantages of marble square ruler:

1. After long-term aging, the rock has a uniform organizational structure, a small coefficient of linear expansion, disappearance of internal stress, and no deformation, therefore.

2. Good rigidity,.

3. Not afraid of acid and alkali erosion, will not rust, does not need to be oiled, is not easy to stick to dust, easy to maintain, and has a long service life.

4. No scratches, not hindered by constant temperature conditions, and able to maintain temperature measurement accuracy at room temperature.

5. Non magnetized, able to move smoothly during measurement, without any sluggishness, not affected by moisture, and the plane is properly weighed.

A marble square ruler is a measuring tool, abbreviated as an angle ruler, and in some cases also known as a guiding rule, used to detect the verticality of workpieces and their relative positions, and sometimes used for marking lines.

The main mineral components of a marble square ruler are calcite, plagioclase, a small amount of olivine, biotite, and trace amounts of magnetite. It has a black color and a structural code. After billions of years of aging, the texture is uniform, the stability is good, the strength is high, and it can be maintained under heavy loads. Marble square ruler is suitable for industrial production and laboratory measurement work.

Used for detection, measurement, marking, equipment installation, and industrial engineering construction

Marble square ruler is suitable for verticality inspection, installation, processing positioning, marking and other important measuring tools in the machinery industry for machine tools, mechanical equipment and components. Its characteristics are good stability and easy maintenance.
