As the market demands higher machining accuracy and precision stability for machine tools, manual operation of machine tools no longer meets the development trend of the times. This has also promoted continuous upgrading of the domestic machine tool industry and the rapid development of the CNC machine tool and turntable industry. The initial development model of CNC machine tool functional components in China is the parallel development of two methods. One is that specialized accessory manufacturers of CNC turntables, power chucks, and ball screws are developing towards CNC accessory products; the other is the supporting functional components independently developed by host manufacturers, such as CNC tool turrets, and some tool magazines and spindles.

The CNC turntable is an important component of CNC machine tools. With the launch of the national "CNC machine tools and basic manufacturing equipment" project, the development of the machinery equipment industry has accelerated, especially the rapid development of the CNC machine tool industry in the "high-speed, high-precision, complex, and intelligent" industry, and the corresponding CNC turntable bearings are also developing rapidly.

However, due to the relatively low level of relevant technologies, the application demand for domestic CNC turntables in China is mainly concentrated in the low-end field, while the consumption demand for products is met by the import market. High-precision CNC turntables from Germany and Japan are exported in large quantities to the Chinese market, and the market competitiveness of Chinese local enterprises is not strong. With increasingly fine division of labor and the expansion of specialized collaborative production, the production and development capabilities of host factories are limited. Most machine tool factories no longer follow the traditional practice of independent development and production of functional components in past product development, but choose the path of professional factory supporting. The function of OEM parts is weakening, and it is even obvious that they are determined not to do the components and accessories that professional factories can do well. The CNC turntable forms a social supporting system, and the future trend of domestic substitution will become increasingly obvious. This is the inevitable result of market economic development, and it is also the only way to improve product quality, shorten delivery time, reduce costs, and achieve large-scale production.

Structure of the CNC turntable: 1. The integrated design of the base can ensure the high rigidity and high precision of the turntable. 2. The servo motor must be used with the driver to match various CNC systems. 3. A special three-stage clearance structure is adopted to ensure high-precision and stable operation. 4. NSK precision bearings are used to ensure high rigidity and high torque output of the gear.

The five-axis CNC turntable has the advantages of small size and high precision, can enhance rigidity, and meet the processing requirements of five-axis linkage. The five-axis CNC turntable is perfectly applied to the high-precision manufacturing industry and can effectively solve the problem of insufficient rigidity of the harmonic reducer. As we all know, there are many methods for machining mechanical parts in modern mechanical manufacturing: in addition to cutting, there are casting, forging, welding, stamping, extrusion, etc., but parts with high precision and low surface roughness generally need to be completed on machine tools through cutting. Therefore, the design of the five-axis CNC turntable is aimed at metal cutting machine tools and can be installed on drilling and tapping machines, 650 machining centers, drilling and tapping machines, and machine tools.
