Precision Integral 2-Axis Motorized Stage EPSD Series
Dual-axis integral orthogonal design with high precision and a compact structure.; High-quality ball-screw drive meets the requirements of high precision and high repetition frequency.; Precision cross-roller guides combined with high-precision slider guides for smooth motion and high load capacity.; A central clear aperture can be fitted with glass or an aluminum-alloy cover for flexible use in different industrial settings.; Standard two-phase stepper motor; five-phase stepper or servo motors can be fitted as required.; A brake motor is required for vertical use.
Product Introduction
The EPSD series precision integral 2-axis motorized stage uses an integral two-dimensional design and stepper-motor control to automate XY spatial displacement. It was developed to meet the need for integral 2D planar motion in industrial production lines, automated machining equipment and automated inspection equipment. It uses cross-roller guides and linear slider guides with ball-screw transmission and an integral structural design that effectively improves orthogonality and motion accuracy. A clear aperture is provided in the center, which can be fitted with glass or a fluorescent plate for transmission, reflection and scattering scan-alignment observation.
