Product description
Marble flat ruler is mainly used for the measurement of flatness and straightness of machine table, guide rail and precision working surface.
Marble flat ruler, also known as granite flat ruler, rock flat ruler, parallel flat ruler, flat ruler, etc., are all precision measuring tools made by manual grinding of natural “Jinan Green”.
The marble flat ruler is an ideal datum for the inspection of instrumentation, precision tools and mechanical parts, and the marble ruler is especially suitable for high-precision measurement.
Marble flat rule features:
1. Physical characteristics: Specific gravity: 2970~3070kg/m2 Compressive strength: 245~254N/mm2 Strong grinding capacity: 1.27~1.47N/ mm2 Linear expansion coefficient: 4.6×10~6°C Water absorption rate: 0.13% Xiao Strength: HS70 or above.
2, marble through long-term natural aging, precise structure, uniform texture, expansion factor is very small, internal stress will not exist, and will not deform.
3, good rigidity, high hardness, especially strong wear resistance, so the precision retention is very good.
4, do not love the temperature effect, flatness retention is very good, do not have to worry about the deformation and accuracy of the appearance due to temperature changes.
5, marble flat ruler will not appear scratches, no magnetic hair should be generated, can smoothly move back and forth when detecting, no stagnation and movement is not flexible.
6, not afraid of acid, lye erosion, will not rust, maintenance and maintenance is also very simple, long service life.
7. Each piece of marble flat ruler has a lightening hole for easy access during use
