Motion control products manufacturer Aerotech Inc. (www.aerotech.com) has integrated a pneumatic collet chucks on the CCS series rotary stage to deliver good run-out characteristics to applications demanding high precision gripping of tubular components.
Featuring a clear aperture for product feedthrough, the patent-pending rotary stages also offer mounting features that support customer-supplied wet-cutting accessories as well as a direct-drive encoder and brushless motor.
The CCS series offers automated materials handling for a vast variety of applications and materials. Its integrated collet chucks accept Levin-, C- or D-style collets offered by machine tool component suppliers and available in sizes supporting tube diameters measuring between 0.1 and 27 mm.
During clamp/unclamp cycles, the rotary stages’ captive collet-chuck design allows for workpiece advancement even without manual realignment that will compensate for axial tube motion. To reduce the workpiece’s axial motion, the taper should be moved around the collet instead of drawing it into the taper. This will also eliminate the need for part re-registration after tube advancement while increasing system throughput.
To prevent collet-chuck failure and encoder contamination, the CCS series tolerate moderate fluid leakage in the aperture, which is vital during wet-cutting operations.
Positioning performance of the stages is maximized, thanks to the direct-drive brushless motor technology, which is optimized for 24/7 production environments. With no belts or gear trains to maintain and brushes to replace, the direct-drive technology offers higher top speeds and quicker acceleration than belt- or gear-driven mechanisms.
