PITTSBURGH, May 21, 2012 — The CCS series rotary stages from Aerotech Inc. feature integrated pneumatic collet chucks; a clear aperture for product feedthrough; mounting features on the housing that support customer-supplied wet-cutting accessories; and a direct-drive brushless motor and encoder. The patent-pending rotary stages provide automated materials handling for a wide range of materials and applications. Collet chucks used with the CCS family accept C-, D- or Levin-style collets that are available from machine-tool component suppliers in sizes supporting tube diameters from 0.1 to 27 mm. The collets provide good run-out characteristics for applications requiring high-precision gripping of tubular materials. The captive collet-chuck design enables workpiece advancement without manual realignment to compensate for axial tube motion during clamp/unclamp cycles. By moving the taper around the collet instead of drawing the collet into the taper, axial motion of the workpiece is reduced, increasing system throughput and eliminating the need for part re-registration after tube advancement. The stages tolerate moderate fluid leakage into the aperture, which is inevitable during wet-cutting operations. This helps to prevent encoder contamination and collet-chuck failure to minimize machine downtime. The direct-drive brushless motor technology maximizes positioning performance. Direct-drive technology is optimized for 24/7 production environments, with no brushes to replace and no gear trains or belts to maintain. It also provides quicker acceleration and higher top speeds than gear- or belt-driven mechanisms.
