The 0801302 support ring is a fundamental component of the opening and closing system of the main spindle collet on Gildemeister DMG-Mori AS16 and AS20 multispindle lathes. Its function is to provide a stable support surface for the clamping fingers, allowing their movement and the correct transfer of the force required to close the collet. Thanks to the precision of the ring, the pilot pads can perform the clamping movement uniformly, without play and with perfect alignment. Proper support of the pivot point ensures that the collet opens and closes with the correct force, maintaining cycle repeatability and preventing gripping errors, abnormal vibrations and uneven wear. A worn ring can alter the working angle of the pilot pads, compromising the effectiveness of the clamping action and the stability of the machining process. Replacement of the ring is recommended when signs of wear or loss of precision in the clamping cycle are observed.
