Turning spindle DGZC-23035A2

belt-drivengrease lubricated

Introduction
The DGZC-23035A2 is the synchronous-belt variant in the 230 mm spindle group. Its 48 mm through-hole and 602 mm body length are intended for lathes where timed-belt transmission is preferred over the larger-bore V-belt arrangement of the A1 model. The unit is designed for horizontal installation and can integrate with machine control via the SYNTEC 2256 magnetic ring encoder.
