Large mirror testing
PROJECT BACKGROUND
Our customer SAFRAN REOSC specializes in the production and qualification of large mirrors for major players in the space industry.
CUSTOMER REQUEST
SAFRAN REOSC contacted us to develop a 6-degree-of-freedom solution for positioning loads of up to 1200 kg, including a 360° axis of rotation.
REALIZATION
Symetrie provided a complete solution integrating JORAN-type actuators. These high-resolution actuators incorporate absolute encoders, enabling them to know their exact position, even in the event of a power failure.
This hexapod is associated with an additional 360° rotary axis on the mobile platform, and incorporates a large mirror attachment interface measuring 2.5 m in diameter.
To meet the system’s space constraints, the fixed platform was optimized down to 4 floor-mounted plates.
PROJECT SPECIFICATIONS
■ JORAN hexapod actuators
■ High-precision absolute linear encoders to avoid undesired homing movements
■ 360° rotary axis with a load capacity of 1200 kg
■ Compact dimensions
■ Travel range: ±25 mm and ±2.5°
■ Hexapod resolution: 1 µm in translation / 0.1 µrad in rotation
■ Rotary axis resolution: 10 µrad
