The central helical gear is a key component in the transmission system of Gildemeister AS16, AS20, GS20, GM20 and GM20AC multispindle automatic lathes. Its primary function is to transfer rotational motion to the main bar-holding spindles mounted inside the spindle drum, ensuring uniform, quiet and perfectly synchronised movement. Thanks to its helical tooth geometry, the gear provides optimal load distribution, enhanced operational stability and significantly reduced vibration during high-speed machining.

Proper operation of this gear is essential to maintain machining accuracy and to ensure correct alignment of the spindles during the rotation and indexing phases of the drum. Excessive wear can compromise motion regularity, generate play in the mechanism and affect the dimensional quality of turned parts.

Timely replacement of this component preserves system reliability, reduces machine downtime and ensures stable and continuous torque transmission under all load conditions. The central helical gear is therefore a strategic spare part for guaranteeing efficiency, repeatability and durability in Gildemeister multispindle lathes.
