The body components of the carving and milling machine are made of marble material. The marble platform is a precision reference measuring tool made of stone material, which is an ideal reference surface for the inspection of instruments, precision tools, and mechanical parts. Especially for high-precision measurements, due to its characteristics, cast iron plates pale in comparison. Granite flat plate, precision granite flat plate, granite inspection flat plate, instrument platform, made of Jinan green stone material through mechanical processing and manual precision grinding. Black luster, precise structure, uniform texture, good stability, high strength, high hardness, able to maintain high precision under heavy loads and general temperatures, and has advantages such as no rust, no magnetization, and no deformation.

Characteristics of components of carving and milling machine body:

1. Granite components have undergone long-term aging, with uniform organizational structure, linear expansion coefficient, disappearance of internal stress, and no deformation.

2. Good rigidity, high hardness, strong, and minimal temperature deformation.

3. Not afraid of acid and erosion, not rusting, no need to apply oil, not easy to stick to dust, easy to maintain and maintain, long service life.

4. No scratches will occur, not hindered by constant temperature conditions, and measurement accuracy can be maintained at room temperature.

5. Non magnetized, able to move smoothly during measurement, without any sluggishness, not affected by moisture, and with good flat stability.

The physical properties of the components of the carving and milling machine body:

1. Specific gravity: 2970-3070kg/m3

2. Pressure resistance strength: 2500-2600kg/cm3

3. Elastic coefficient: 1.3-1.5 × 106kg/cm2

4. Water absorption rate:& lt;0.13%

5. Shore hardness: above HS70
