Grinding head DZDA-125-300/600-105/20-A26-A/A

Overview
This single-arm tool grinding head integrates an A63 tool-holder interface with independent tilting and rotary axes. The tilting axis delivers up to 600 Nm (rated 300 Nm), features water cooling and high pull force, and is designed for integration in automated tool-grinding and laser-processing systems.
