Overview

The main mineral components of the 00 grade marble drilling module platform are pyroxene, plagioclase, a small amount of olivine, biotite, and trace magnetite. It has a black luster, precise structure, and after billions of years of aging, uniform texture, good stability, high strength, and high hardness. It can maintain high precision under heavy loads. Used for industrial production and laboratory measurement work.

Product Details

We will take you to understand00 level marble punching module platformTechnical requirements:

1、 It is recommended not to install handling handles for mechanical components of grade 000 and grade 00 marble.

2、 The dents or missing corners on non working surfaces of marble mechanical components are allowed to be repaired.

3、 Marble mechanical components should be made of fine-grained, structurally dense materials such as gabbro, diabase, granite (biotite should be less than 5%, elastic modulus should be greater than 0.6 × 10-4kg/cm2, water absorption rate should be less than 0.25%), etc. The working face hardness should be greater than

4、 The allowable surface roughness Ra of the working surface of marble mechanical components is 0.32~0.63um.

5、 The flatness tolerance of the working surface of marble mechanical components is specified in Table 1.

6、 The perpendicularity tolerance of the side of the marble mechanical component to the working surface and the perpendicularity tolerance of the two adjacent sides of the marble mechanical component shall comply with the 12th level specified in GB/T1184.

7、 When using diagonal or grid methods to inspect the flatness of marble mechanical components, the fluctuation of the air plane should be checked. The fluctuation of the working plane is specified in Table 2.

8、 The concentrated load area, rated load applied, and allowable deflection values at the center of the marble mechanical component working face are specified in Table 3.

9、 The working surface of marble mechanical components shall not have defects such as sand holes, air holes, cracks, slag inclusions, shrinkage, scratches, bumps, rust, etc. that seriously affect the appearance and performance.

10、 If threaded holes (or grooves) are set on the surface of grade 0 and grade 1 marble mechanical components, their positions should not be higher than the working surface.

00 level marble punching module platformWhat is compressive strength and the compressive strength of stone?

Compressive strength refers to the ability of rocks to resist damage under unidirectional compression. The magnitude of compressive strength indicates the hardness of the rock. The compressive strength is expressed in MPa, with 1MPa=10.2 kg/c ㎡ (kgf/cm2) and one standard atmospheric pressure=760 mmHg=76 cmHg=1.013 × 105 Pascal=0.336 mH2O.

In order to ensure that the standard atmospheric pressure is a constant value, the 10th International Conference on Weights and Measures in 1954 declared that the standard atmospheric pressure value is 1 standard atmospheric pressure=101325 Newton/square meter. According to the "JC205-92 Natural Granite Building Board" standard, the dry compressive strength should not be less than 60.0 MPa.

According to the "JC79-92 Natural Marble Building Board" standard, the dry compressive strength of marble shall not be less than 20.0MPa.

Generally speaking, the compressive strength of granite is between 110-245MPa, and the compressive strength of marble is between 70-110MPa.
