В чем преимущества мраморных воздухоплавательных платформ?
- Ultra-high stability and shock-absorbing performance
Mar air-float platforms are equipped with natural granite or artificial marble bases, featuring an extremely low thermal expansion coefficient and excellent shock-absorbing performance. Compared to traditional metal platforms marble bases effectively absorb high-frequency vibrations, ensuring absolute stability for equipment during micrometer or even nanometer-level operations. - Zero-friction air-float
The platform is equipped with high-precision air bearings, which use compressed air to form a uniform air film, achieving **zero-friction, wear-free motion. This technology not only significantly extends the lifespan of equipment but also eliminates the return error and stick-slip effect caused by traditional mechanical slides, making the motion smoother and more precise - Nanometer-level positioning accuracy
Combined with high-resolution linear motors or servo drive systems, the Bellkin marble air-float platform can achieve -micrometer or even nanometer-level repeat positioning accuracy, meeting the stringent requirements of the semiconductor lithography, ultra-precision machining, and optical detection industries. - Modular design for flexible adaptation
The platform supports multi-axis linkage and can be customized into single-axis, dual-axis, or multi-axis systems according to customer needs. It is also compatible with various sensors, optical components, and automation equipment, easily integrating into existing production lines or R&D systems. - What is an Airearing Granite Platform?
An air bearing granite platform is a high-precision motion control system that employs natural granite or artificial marble as the base and integrates air bearings (air-ating guides) to achieve frictionless, highly stable precision motion. It is widely used in semiconductor manufacturing, optical inspection, precision measurement, micro-nano processing, and other fields It is one of the core components of high-end equipment such as lithography machines, three-coordinate measuring machines, and laser processing equipment. - Core Components1. Granite/Marble Base
- Made of high-stability natural granite or artificial marble, it has a low coefficient of thermal expansion, high rigidity, strong shock resistance, ensuring the platform is not affected by temperature changes and external vibrations.
- Air Bearings (Air-Floating Guides)
- Form amicro-sized air film** between the moving parts and the base through compressed air, achieving zero friction and no wear suspension motion.
- Drive System
- Typically uses linear motors or high-precision servo motors to ensure nanometer-level positioning accuracy.
- Control System
- Paired with high-resolution enc or laser interferometers, it achieves closed-loop control, ensuring motion accuracy and repeatable positioning.
- Working Principle
The core technology of the air-ating granite platform lies in the air bearings (air-floating technology), and its working principle is as follows: - Compressed Air Supply
- An external air (such as an oil-free air compressor) provides stable, clean compressed air (typically at a pressure of 0.3~0.6 MPa).
. Air Film Formation - Compressed air enters the air bearings through precision throttle holes, forming a uniform micro-sized air film (usually 5~20 μ) between the moving parts (such as the slide table) and the granite base, allowing the moving parts to “float” above the base.
- Zero Friction Motion- Due to the presence of the air film, there is no physical contact between the moving parts and the base, eliminating the friction, wear, and crawling (stick-ip effect) of traditional mechanical guides, making the motion smoother and more accurate.
- High-Precision Positioning
- Combined with linear motors or servo drives and-resolution feedback systems (such as grating scales or laser interferometers), it can achieve nanometer (nm) or sub-micrometer (0.1 μm) accuracy.
