Machining spindle DQFH-02440/2.5

motorizedwater-cooledmanual tool change

Overview
Within the 82 mm dicing spindle family, the DQFH-02440 is engineered for higher continuous output rather than peak speed. It delivers 3 kW and 0.6 N·m at S1 using air bearings, a synchronous motor and water cooling, making it suitable for industrial wafer dicing applications.
