Granite base application: Granite has extremely stable physical properties, dense and uniform internal structure, low coefficient of thermal expansion, high hardness. This makes the base can effectively isolate external vibration, reduce the impact of ambient temperature changes on the accuracy of the platform, and has good wear resistance, long-term use can also maintain stable support performance, providing a solid foundation for the accuracy of the platform.
High-precision mechanical structure design: The mechanical structure of the platform has been carefully designed and optimized, using high-precision guide rails, lead screws, bearings and other transmission components. With low friction, high stiffness and good motion repeatability, these components can accurately transmit power and control the movement of the platform, reducing the accumulation of errors during movement. For example, the use of aerostatic guide rail, the use of air film to support the movement of the platform, with no friction, no wear, high precision, can achieve nanoscale positioning accuracy.
Advanced active vibration isolation technology: equipped with an active vibration isolation system, real-time monitoring of the vibration status of the platform through the sensor, and then according to the monitoring results, feedback control of the actuator, generating the opposite force or movement of external vibration to offset the impact of vibration. This active vibration isolation technology can effectively isolate low and high frequency vibration, so that the platform can remain stable in the complex vibration environment. For example, the electromagnetic active vibration isolator has the advantages of fast response speed and accurate control force, which can reduce the vibration amplitude of the platform by more than 80%.
Precision control system: The platform adopts advanced control system, such as the control system based on digital signal processor (DSP) or field programmable gate array (FPGA), which has the ability of high-speed calculation and precise control. The control system monitors and adjusts the movement of the platform in real time through accurate algorithms, and realizes high precision position control, speed control and acceleration control. At the same time, the control system also has good anti-interference ability, and can work stably in complex electromagnetic environment.
High-precision sensor measurement: The use of high-precision displacement sensors, Angle sensors and other measuring equipment, real-time accurate measurement of the movement of the platform. These sensors feed the measurement data back to the control system, and the control system makes accurate adjustment and compensation according to the feedback data to ensure the motion accuracy of the platform. For example, the laser interferometer is used as a displacement sensor, and its measurement accuracy can be up to nanometers, which can provide accurate position information for high-precision control of the platform.
Error compensation technology: By modeling and analyzing the errors of the platform, the error compensation technology is used to correct the errors. For example, the straightness error of the guide rail and the pitch error of the lead screw are measured and compensated to improve the motion accuracy of the platform. In addition, software algorithms can also be used to compensate the errors caused by temperature changes, load changes and other factors in real time to further improve the accuracy of the platform.
Strict manufacturing process and quality control: In the manufacturing process of the platform, strict manufacturing process and quality control standards are adopted to ensure the processing accuracy and assembly quality of each component. From the selection of raw materials to the processing, assembly and commissioning of parts, every link is strictly inspected and tested to ensure the overall accuracy and performance of the platform. For example, high-precision machining of key parts is carried out, and advanced equipment such as CNC machining centers are used to ensure that the dimensional accuracy and form and position tolerances of parts meet the design requirements.
