The granite crossbeam module base is made of granite and is used to support and fix the basic components of the crossbeam module. It is widely used in precision instruments, CNC machine tools, and other fields. This type of base is widely used in high-precision CNC machine tools, semiconductor manufacturing equipment, precision measuring instruments and other fields, and is a key component to ensure long-term stable operation and machining accuracy of equipment.
structural characteristics
Material characteristics: Made of granite, with a black luster, precise structure, and uniform texture. Its physical properties are stable, with high hardness, strong strength, strong wear resistance, small coefficient of linear expansion, and it does not rust, resist acid and alkali, or magnetize.
Processing accuracy: Generally made through mechanical processing and manual precision grinding, it can be drilled and slotted according to customer needs, achieving high precision requirements such as flatness and parallelism.
Combination form: Generally assembled by combining marble beams and marble columns, there are also integrally formed ones, which are determined according to customer needs.
Performance Characteristics
High stability: Granite has a long growth process and no internal material tension, ensuring that the base maintains a stable geometric shape for a long time without being affected by time and environmental factors, providing stable support for the equipment.
Good thermal stability: The coefficient of thermal expansion is low, only half of that of steel and a quarter of that of aluminum. When the temperature changes, the size of the base changes very little, which can effectively ensure the accuracy of the equipment.
Good shock absorption performance: With excellent damping performance, it can absorb and attenuate external vibrations, reducing the impact of vibrations on equipment operation and measurement accuracy.
High precision retention: Granite has high hardness and strong wear resistance, with a surface that is not easily worn, and can maintain high precision for a long time, reducing the problem of precision decline caused by base wear of equipment.
It mainly undertakes the following functions:
Stable support: As the basic framework of the module, it provides a solid installation platform for components such as beams and skateboard seats, resisting various forces and vibrations generated during processing or measurement.
Accuracy guarantee: Granite material itself has high rigidity, high stability, wear resistance, and small thermal deformation, which can effectively reduce the impact of environmental temperature changes or equipment operation on accuracy. It is an ideal base material for precision machine tools and measuring equipment.
Modular foundation: Its design usually follows the modular concept, making it easy to combine with components such as crossbeams and skateboard seats of different specifications to achieve rapid configuration and functional expansion of equipment.
