In this section, the precision manufacturing processes for small-size rotary tables, spindles, and guideways were analyzed and discussed in detail. The section began by listing several types of small-size linear and rotary components commonly used in high-precision machinery. These components, which are crucial for various applications such as CNC machines, robotics, and aerospace systems, require careful consideration of their materials, geometries, and performance characteristics. A particular focus was placed on the manufacturing process of small-size aerostatic spindles, which are essential for applications demanding ultra-precision and minimal friction. The aerostatic spindle’s production involves several key steps, each contributing to its high performance. The materials selected for the spindle are critical to its durability and precision, typically involving high-grade alloys and composites that offer both strength and stability. Precision in manufacturing is paramount at every stage, with tolerance levels often in the micrometer range to ensure smooth operation and minimal wear. Advanced techniques, such as CNC machining, surface grinding, and aerostatic bearing design, are employed to maintain the spindle’s performance and efficiency. The use of aerostatic bearings, in particular, allows for contact-free operation, reducing friction and heat generation, which is crucial for maintaining high rotational speeds and precision over time. Each step in the production process is closely monitored and refined to ensure the spindle meets the stringent requirements for its intended applications, ensuring optimal performance in demanding environments.
