The AR-5c is TJR’s pneumatic collet rotary table that employs a pneumatic brake and 5c collet closer system. This unit is an affordable solution for customers who require a 5c collet for their workpiece as an alternative to a 3 or 4 jaw chuck.
The AR-5c unit can be integrated into a CNC machine control as a full 4th axis or it can be operated as an indexer by utilizing TJR’s SAC (Single Axis Controller). In addition this series is offered in Right Handed and Left Handed motor mount configurations with a powerful pneumatic braking system.
The AR-5c unit is manufactured with a radial-axial preloaded bearing system for high rigidity that can perform light or heavy cutting. The AR-Series uses a dual lead worm shaft and worm gear to ensure long term indexing accuracy in both directions.
