Motor-driven rotary table RAB series

horizontalfor machine toolsfor machining centers

Overview
The RAB series rotary and swivel tables are double-supported, direct-drive precision axes designed for demanding machining tasks. Water-cooled torque motors provide extreme acceleration, high continuous and peak torques and truly backlash-free operation. High-resolution encoders deliver positioning accuracy down to ±5 angular seconds. Flexible customisation options allow integration into a wide range of machine concepts.
