Aerotech (Pittsburgh, PA) offers the CCS series rotary stages with integrated captured collet chucks that provide automated material handling for a wide range of materials and applications. Collet chucks used with the stages accept C-, D-, or Levin-style collets from machine-tool component suppliers in sizes supporting tube diameters from 0.1 mm to 27 mm. The stages feature a collet-chuck design that allows workpiece advance 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 significantly reduced, eliminating the need for part reregistration after tube advancement. The stages use direct-drive brushless motor technology that is optimized for 24/7 production environments, with no brushes and no gear trains or belts.
