Precision Motion Control Solution for A Leading Research University
When a leading Research University required a specialized motion control solution for high-performance scanning within a rectangular vacuum chamber, they turned to H2W Technologies. The challenge involved developing a system capable of operating at a vacuum of down to 10^-6 mbar while maintaining precise environmental integrity in a vertically mounted configuration. The application necessitated the scanning of light sources across a targeted 24" by 59" area, and thus required little to no outgassing that would disrupt their experiment. To maximize efficiency and meet demanding research timelines, the university required the rail system to complete full-area scans within a strict window. This required a delicate balance between speed, precision, and the physical constraints of a high-vacuum environment.
The H2W Solution: Custom Dual-Axis Engineering
H2W Technologies engineered a custom dual-axis linear rail system designed for a compact footprint within restricted chamber volumes. The implementation of an outboard bearing design on the horizontal axis allowed for a simple drive mechanism that would not require complex programming. This also maximizes available space while delivering 16.5 lbs of continuous force and 1-micron resolution. The resulting system provided a seamless "drop-in" mounting path for the researchers, ensuring reliable motion in vacuum-restricted volumes. The technical specifications of the final installation included:
- Vertical Stroke: 51.3 inches
- Horizontal Stroke: 22.5 inches
- Resolution: 1 micron encoder on both axes
- Force: 16.5 lbs of continuous force available on both axes
- Drive System: Brushless linear motors in a Single Rail Positioning Stage Configuration
- Environmental Rating: Validated for 10^-6 mbar high-vacuum operation
- Total System Mass: 115 lbs
