High-Precision 4th-Axis Indexer for CNC Machining Centers
Product Overview
The RN-100 CNC Rotary Table is a compact, lightweight 4th-axis solution with a φ80 mm spindle bore and φ135 mm table. Weighing only 28 kg and driven by a FANUC αiF2 servo motor with 1/36 gear ratio, it achieves 83.3 min⁻¹ max rotation speed — the fastest in the series. Ideal for small machining centers, drill-tap machines, and space-limited automation setups.
