The advantages of adding a turntable to a cobot/robot setup

Synchronised turntables act as an additional axis that the robot can control synchronously while performing a movement. Usually driven by a servo motor or a direct-drive motor, these tables provide the precision and power required for sanding, grinding and polishing applications. They combine the advantages of the other turntable types and are suitable for precision sanding and edge deburring, as well as for repositioning workpieces during processing. This ensures a constant feed rate of the tool against the workpiece, resulting in a uniform sanding pattern across the entire surface.

Controlling turntables introduces additional complexity into the programming process. Turntables without positioning capabilities are easier to implement than synchronised versions. For synchronised turntables, advanced software is required, such as the SprutCAM system, which manages the movements and coordination between the robot and the turntable.

Cibo Robotics uses all three types of turntables when assembling robotic cells. They often combine an indexing table with two synchronised turntables. The cell always includes a turntable positioned outside the enclosure, allowing the operator to change workpieces safely and away from dust. The synchronised turntable is controlled via SprutCAM, where all parameters are stored within the programme. This CAM programme manages the movements and coordination between the robot and the turntable.
