It features a backlash-free gearbox on the J5 axis and rigid connections across all joints to minimize high-speed vibration. The robot utilizes NURBS trajectory planning and variable speed\/acceleration planning for maximum efficiency. A custom wrist motor provides strong torque for high-inertia applications. Key advantages include a wide reach range, high rigidity, high speed, and high inertia. Application areas include handling, assembly, torquing and fastening, gluing, spot welding, and loading\/unloading. The robot has a repeatability of \u00b10.06mm and wrist protection rated at IP65. Case studies include solutions for LCD TV manufacturing, automated palletizing, and industrial robot smart welding for ships."},"faqs":[{"question":"What is the payload capacity of the SIASUN SR270A-220\/3.21 robot?","answer":"The SIASUN SR270A-220\/3.21 robot has a payload capacity of 220 kg (485 lbs)."},{"question":"What is the reach of the SR270A-220\/3.21 robot?","answer":"The SR270A-220\/3.21 robot has a reach of 3218 mm."},{"question":"What applications is the SIASUN SR270A-220\/3.21 suitable for?","answer":"This robot is suitable for handling, assembly, torquing and fastening, gluing, spot welding, and loading\/unloading tasks."},{"question":"What is the repeatability of the SR270A-220\/3.21?","answer":"The repeatability of the SR270A-220\/3.21 is \u00b10.06 mm."}],"key_points":["Payload of 220 kg and reach of 3218 mm.","Backlash-free gearbox on J5 axis for high rigidity.","NURBS trajectory planning for efficient operation.","Custom wrist motor for high-torque, high-inertia tasks.","Applications include handling, assembly, welding, and gluing.","Repeatability of \u00b10.06mm and IP65 wrist protection."],"target_audience":"Manufacturing engineers, automation integrators, and industrial buyers seeking a high-payload, high-rigidity robot for tasks such as welding, handling, and assembly in industries like automotive, shipbuilding, and electronics manufacturing.","semantic":{"categories":["Large Payload"],"tags":[],"primary_category":"Large Payload"},"source":{"generated_by":"manual"}}}
