The collet chuck on the ASR1200 accepts ER161 series collets. These collets are readily available in sizes that support tube diameters from 0.5 mm to 5.8 mm. The collet is retained with a threaded retaining cap that enables quick changeover. The collet is configured in a "fail-safe" mode where full clamping force is applied when no air pressure is present. Air is delivered to the rotating collet assembly through a custom-designed frictionless, seal-less rotary union. This 100% noncontact rotary union design ensures a lifetime of maintenance-free operation. The combination collet chuck and rotary union also has significantly less friction and inertia than external assemblies created from discrete parts. This reduced inertia improves system performance by allowing higher peak acceleration and reducing position error during laser machining operations.
The ASR1200 includes a fluid delivery system and seal assembly to support wet cutting processes. The rear of the unit has a quick release fitting for fluid input and an NPT thread that allows the user to customize the length of the "water jacket" to match the length of the tube material. Inside the ASR1200 is an O-ring assembly that seals the tubing against the I.D. of the ASR1200 shaft. This seal assembly rotates with the tubing, eliminating troublesome torsion-induced errors that are present when working with thin-walled tubing or extremely flexible materials such as Nitinol.
The ASR1200 series utilizes direct-drive brushless motor technology to maximize positioning performance. Direct-drive technology is optimized for 24/7 production environments because there are no brushes to replace and no gear trains or belts to maintain. Direct drive also provides quicker acceleration and higher top speeds than gear- or belt-driven mechanisms yielding higher total overall throughput.
The low maintenance and high throughput characteristics of the ASR1200 provide a stage that yields the lowest total cost of ownership while the integral water jacket and pneumatic collet provide unmatched levels of integration and ease of use.
