In common optical debugging, sample plane scanning, precise component alignment, lightweight automated integration and other general working conditions, the side-driven displacement stage has problems of uneven force distribution and large center positioning deviation. The traditional split assembly dual-axis stage has long been plagued by issues such as poor orthogonal accuracy, unstable operation and weak repeatability. To meet the urgent need for precise center positioning, all-round stable operation, universal ultra-thin adaptation and high stability and high load-bearing capacity in routine precision fine-tuning, Saifan Optoelectronics has launched the 7SWA04 White Elephant series electric dual-axis translational stage. With a classic ultra-thin integrated base, center screw drive architecture and high-precision transmission configuration, it takes into account spatial adaptability and all-round positioning stability, becoming a high-performance main model for two-dimensional general precision displacement and high-frequency routine fine-tuning.
Ultra-thin integrated center architecture, center-driven more stable, orthogonality stronger
The 7SWA04 series continues the classic ultra-thin integrated design of the White Elephant series, discarding the split assembly structure and side-driven layout, adopting an exclusive screw center drive architecture, achieving X and Y two-dimensional automatic synchronous electric translation, is a versatile dual-axis translational stage suitable for general precision working conditions. The center-symmetric drive structure makes the platform surface evenly stressed, the transmission is centered and symmetrical, completely solving the industry problems of deviation in both ends of the side-driven, imbalance of force distribution, and uneven overall precision, and significantly improving the consistency of all-round displacement. Based on the overall integrated molding process, the two axes have unified benchmarks and regular layouts, naturally having extremely high orthogonal accuracy, fundamentally eliminating the problems of coaxiality deviation, cumulative errors, and long-term running offset of split equipment.
The entire machine is extremely streamlined and thin, with compact thickness, no occupation of installation space, balanced rigidity and stability, truly achieving lightweight body without reducing stability performance. The center drive combined with a flat platform is suitable for center alignment, all-round scanning, and multi-point uniform fine-tuning in various common working conditions, with extremely high scene compatibility.
