Can be connected to a machine’s control or run with TJR’s SAC (Single Axis Controller) for M-code use
Available in 1 degree or 5 degree indexing increments
Can rotate without lifting of the table to prevent table from water and particle damage
TJR Hirth Coupling CNC Index Table
The HI-Series is TJR’s hydraulic brake 4th axis rotary table that is equipped with a three-piece Hirth coupling. This series is offered in sizes ranging from 255mm (10.03”) to 500mm (19.68”) face plate diameter.
These rotary tables are capable of being mounted in both the vertical and horizontal position. The HI series also offers a reduced sheet metal design that is suitable for tight vertical or horizontal applications. They are capable of being used as a full 4th axis that is integrated into the CNC machine control or as an indexer with the use of TJR’s SAC (Single Axis Controller) for M-code use.
