As its name implies, the precision turntable is designed to perform rotational motion and output specific torque for high-precision positioning. Widely applied in various fields, it serves critical roles in high-precision measurement, optical inspection & manufacturing, and nanofabrication technology.
As a type of precision equipment in the monitoring industry, turntables can be classified based on different criteria:
- Axis Configuration: Single-axis, dual-axis, three-axis, and multi-axis (with over three axes) turntables.
- Functional Types: Dual-axis position turntables, rate turntables, and acceleration turntables.
- Technical Features: Magnet-free turntables and temperature-controlled turntables.
- Rotational Speed: High-speed turntables and ultra-high-speed turntables.
- Operation Mode: Manual turntables and motorized turntables.
This classification system enables precise matching of turntable capabilities to specific application requirements, ensuring optimal performance in scientific research, industrial manufacturing, and quality control scenarios.
Turntable slip rings, an emerging application category of slip rings, can be categorized into simulated turntable slip rings and test turntable slip rings based on their usage scenarios. Specifically designed for turntable applications, these conductive slip rings are predominantly utilized in high - end fields such as military turntables. As a result, stringent requirements are imposed on product size, signal transmission, and performance. Slip ring manufacturers are not only expected to possess robust technical capabilities but also to implement strict quality control measures and offer excellent after - sales service.
In diverse applications, turntables have varying requirements regarding current, voltage, number of channels, as well as communication and control signals. Frequently, in numerous applications, the simultaneous transfer of liquids or gases is essential to ensure the proper functioning of hydraulic and pneumatic components on the rotary table. For most turntables, it is necessary to transmit power, measurement signals, control information, and communication data to the turntable. Moreover, turntables often operate at extremely high speeds, sometimes reaching up to 20,000 RPM. Therefore, the key challenge lies in ensuring that the slip ring can achieve reliable power transmission, stable signal transfer, and minimal attenuation at such high rotational speeds.
Leveraging its extensive R&D and manufacturing experience in the slip ring industry, integrating principles of friction mechanics, electronics, materials science, and relevant standards, and adopting advanced processing techniques, SPR-ing Optoelectronics has developed a high - speed slip ring. This innovative product provides an effective solution for high - speed precision equipment that requires low - current or signal transmission between the rotating platform and the stationary platform. It fundamentally overcomes the limitations of traditional conductive slip rings, such as low rotational speed and poor wear resistance.
Turntable slip rings developed by SPR-ing Optoelectronics have been successfully tested on various equipment, including multiple test turntables and simulation test turntables. These slip rings feature low torque, minimal resistance fluctuation, a compact design, multiple channels, diverse signal types, small size, and high - performance capabilities. Currently, the company's slip rings for precision turntables mainly include the following representative products:
