A new range of ultra-low profile, precision rotary stages aimed at automated material handling applications has been launched by Aerotech. The new ACS LP series feature high torque, direct drive brushless servomotors and integrated air operated collet chucks for tube and bar diameters from 0.5 mm to 16 mm. With low inertia mechanics for fast acceleration and with a maximum speed capability that seriously out-performs conventional worm-wheel driven rotary stages, the range is designed for high-throughput production applications such as precision laser machining and micro-welding for medical device manufacture.
The modular range is available in three nominal widths of 100 mm, 150 mm and 200 mm, each with an air-actuated collet holder for an ER style collet. The ACS-100LP accepts an ER8 series collet, the ACS-150LP accepts an ER16 and the largest sized ACS-200LP uses an ER25 collet. ER collets support tube and small bar stock diameters from 0.5 mm to 16 mm with run-out characteristics that complement the performance of the precision ACS-LP range.
