Our robotic bolt tightening workstation features a 6-axis industrial robot equipped with a tightening spindle mounted at the wrist for precision fastening of bolts on workpieces. The system supports single-spindle tightening for standard applications, and for higher throughput, a dual-spindle indexing configuration is available—with the two spindles dynamically positioned via servo motors in real time to tighten two bolts simultaneously per cycle.

The system incorporates advanced angle control and torque monitoring, with torque data for every bolt logged in real time. Any torque deviations outside specification trigger an immediate visual alarm for instant operator notification.
