Engraving machine components, marble components for engraving machines, granite components for engraving machines

Marble Components: Made from "Jinan Qing" stone material, processed through mechanical machining and hand finishing. Characterized by a black luster, dense structure, uniform texture, excellent stability, high strength, and hardness, these components can maintain high precision under heavy loads and general temperatures. They also boast rust resistance, wear resistance, non-magnetization, and non-deformation advantages.

Characteristics of marble components:

1. Marble components, after long-term aging, feature uniform tissue structure, exceptionally low linear expansion coefficient, and internal stress elimination, without deformation.

2. High rigidity, high hardness, excellent wear resistance, and minimal temperature deformation.

3. Resistant to acid and erosion, non-corrosive, oil-free, dust-resistant, easy to maintain, and long-lasting.

4. No scratches, unaffected by temperature control, and maintains measurement accuracy at room temperature.

5. Non-magnetizable, smooth movement during measurement with no sticking sensation, unaffected by humidity, and flat stability.

Physical Properties of Marble Components:

1. Specific Gravity; 2970-3070 kg/m³

2. Pressure Resistance: 2500-2600 kg/cm³

3. Elasticity Coefficient: 1.3-1.5 x 10^6 kg/cm^2

4. Water Absorption: ＜0.13%

5.肖氏硬度: HS70 and above
