The FAR-Series is TJR’s pneumatic brake tilt cradle type dual arm rotary table line and is offered in multiple sizes and configurations. The FAR models featured here are TJR’s tilt cradle type dual arm rotary tables.
The sizes range from 125mm (4.92”) to 210mm (8.26”) face plate diameter. The FAR-Series is ideal to convert your traditional 3 axis milling machine into a 5 axis machine for a portion of the cost of a new full 5 axis machine. They are capable of being fully integrated into your current machine control so you can utilize as a full rotating and tilting axis for true 5 axis work. It is also capable of being used as a full 4th and 5th axis connecting to TJR’s DAC (Dual Axis Controller) in the event that you need to utilize the unit on multiple machine tools.
The FAR series is manufactured with large-diameter radial-axial preloaded bearing system for high rigidity that can perform light or heavy cutting.
