The locking pin cam designed for Gildemeister AS16, AS20, GS20, GM20 and GM20AC multispindle automatic lathes is a key component in the indexing system of the spindle drum. During the machine cycle, the rotation of the cam raises the <strong>locking pin</strong>, releasing the spindle drum and allowing it to rotate and shift into the next position. As the cam continues its motion, it lowers the locking pin back into place, locking the drum in a rigid, stable and precisely aligned position to ensure consistent accuracy during high-speed production.

This sequence occurs quickly and within the machine’s idle intervals, without affecting the machining cycle. Because it ensures correct drum positioning and proper indexing, the cam is considered a critical wear part, and its replacement is essential to maintain precision, eliminate play in the drum and preserve the overall efficiency of the machine during extraordinary maintenance. A new and properly functioning cam prevents misalignment, vibration issues and indexing delays, improving long-term process reliability.
