The high-speed, direct-drive rotation stages from PI (Physik Instrumente) LP have been fitted with brushless, frictionless, and closed-loop torque motors. The availability of such fast rotary tables offers the ideal combination of high velocity, high precision, and utmost service life. Manual Linear Translation Stage
PI offers closed-loop direct-drive rotary tables with mechanical and air bearings. The stage model comes with a low profile and large apertures. The stage design has been improved for high stiffness, speed, and load capacity.
Air-bearing rotation tables are recommended if maintenance-free and friction-free motion with an unlimited lifetime is needed. Such ultra-precision, high-speed rotary tables offer vibration-free motion with extremely high precision and negligible runout, wobble, and eccentricity errors.
The deficiency of lubricants makes these clean rooms consistent and ideal for any high-performance metrology application in photonics, optics, and semiconductor manufacturing, test, and metrology-related projects.
In opposition to belt-drive rotation stages or worm gear-driven rotary stages, the quick, direct-drive stages remove play in gears, couplings, or flex in drive belts, offering accurate rotary motion with zero backlash and outstanding constancy of velocity while obtaining higher speed compared to worm-gear drives.
High-speed rotary tables are utilized in high-performance factory automation, semiconductor, and laser processi
