Roller Gear Cam and Hybrid Worm/Roller Cam Tilting Rotary Table

The Roller Gear Cam Tilting Rotary Table uses a pure roller cam drive on both axes, delivering zero backlash and high indexing speed. It is best suited for applications requiring precise and repeatable positioning. The Hybrid Worm/Roller Cam Tilting Rotary Table uses a worm gear on one axis. A Roller cam on the other side combines the torque strength of the worm gear drive with the accuracy and low-wear characteristics of the roller cam. This makes the hybrid configuration a better fit for applications that require both clamping rigidity and precise positioning accuracy.

The Hybrid Worm/Roller Cam design of the TJR Tilting Rotary Table solves a challenge in 5-axis tilting rotary tables, balancing torque capacity with positioning precision. The worm gear component handles the load-bearing role, providing strong clamping and resistance to cutting forces on one axis, while the roller cam component delivers the precise backlash-free angular positioning on the other.

The Roller Gear Cam Tilting Rotary Table is well-suited to parts that require a large number of indexing positions with high speed between positions and very tight positional tolerances. Examples include aerospace brackets and frames, turbine components, complex mould cores, medical implants and automotive structural parts with compound-angle features. The zero-backlash roller cam drive of the Roller Gear Cam Tilting Rotary Table ensures each position is hit accurately every time in high-volume production, where thousands of parts are being run consecutively.

The TJR Roller Gear Cam and Hybrid Worm/Roller Cam Tilting Rotary Tables are compatible with major CNC control platforms, including Fanuc, Siemens, Mitsubishi and Heidenhain. The units are supplied with servo drive interfaces and encoder feedback systems that integrate cleanly with these controls. SPT Engineering, as the Supplier of TJR Rotary Table, handles the pre-sales compatibility assessment to ensure the selected table and control system work together correctly from the start.

On a Tilting Rotary Table, both the rotary axis and the tilting axis have clamping systems, typically hydraulic. During machining, both axes are clamped simultaneously, locking the workpiece in position against cutting forces on all planes. The clamping system on each axis is controlled independently through the CNC program, allowing the machine to unclamp, index and re-clamp each axis as needed during the part cycle. This ensures rigidity during every cutting operation, regardless of the workpiece orientation.
