COCOLO inherited the patented turret positioning design from the machinery department of ITRI, which has been patented in Germany, Japan, Taiwan and the USA. The patented hydraulic turret design was extended to servo turret design for greatly upgrading turret performance. The exclusive design of three-piece coupling features high precision positioning. The turret disc does not move out to fully prevent chips and coolant from entering. In addition, the specially designed internal pretensioned mechanism assures outstanding rigidity and accuracy during reverse cutting.
