Rotary module for robots DZDH-125-240-120-30-A26-A2

Introduction
The DZDH-125-A2 precision rotary head is a compact rotary indexer designed for integration into small tool-grinding machines. Cone-face and taper run-out specifications (≤0.002 mm), combined with a 26-bit BiSS-C encoder and tight positioning repeatability, enable accurate tool alignment while the 40 kg unit weight limits added load to the machine structure.
