Turning spindle DGZYC-28003/30-FWVCS

AC motorgrease lubricated

Overview
The DGZYC-28003 is the largest, highest-torque spindle in its series. A 280 mm spindle body, A2-8 nose and an 86 mm through-hole are combined with 30 kW continuous power and 715 Nm peak torque to support large chucking systems and heavy CNC turning operations. Designed for horizontal installation and compatibility with common CNC controls.
