The RTG is a compact, lightweight, tilted rotary table that makes it possible to respond to the increasing number of machining needs of small MCs, the increasing complexity of workpieces, and the increasing size of workpieces.
By using the RTG series equipped with A and C axes you can take advantage of process aggregation, efficient machining postures and tool selection, even when machining workpieces that had previously required multiple processes. In addition, in order to meet the needs of unmanned machines and enjoy the benefits of robots, rotary joints with up to 13 (12 +1) ports are available for automatic installation and removal of workpieces with seating confirmation.
Furthermore, the use of a RollerDrive mechanism eliminates the need for clamping during machining, thus reducing the positioning time by approximately one-third, compared with conventional worm gear rotary tables that use clamps. The RollerDrive mechanism can be operated continuously, with only a short break to change the lubrication oil. It eliminates the need for periodic backlash readjustments like the conventional worm gear rotary tables.
This contributes to significantly reduced equipment maintenance. The RTG is ideal for small MCs, while automating operations and improving productivity.
