Product description

Marble parallel gauges are mainly used for the detection of parallelism and perpendicularity. The main mineral components of the granite parallel gauge are escape stone, plagioclase, a small amount of olivine, biotite and trace magnetite, black color, precise structure, after tens of millions of years of aging, uniform texture, good stability, high strength, High hardness and high precision under heavy load. Suitable for measurement in industrial production and laboratories.

Features and benefits of marble parallel gauges:

1. Good rigidity, high hardness and strong wear resistance;

2. The marble has long-term natural aging, uniform structure, minimal expansion coefficient, complete disappearance of internal stress, no deformation, and therefore high precision;

3, not afraid of acid, lye material erosion, will not rust, no oil, no sticky dust, maintenance-free, easy to maintain, long service life;

4, no magnetization, smooth movement when measuring, no stagnation, not affected by moisture, flatness is stable;

5, no scratches, not subject to constant temperature conditions, can maintain measurement accuracy at room temperature.

Marble parallel gauges are supplied in pairs and should be used in pairs when used.
