Disk-Type Tool Turret 0.5.473.5xx series with Axial Tool Drive Description These turrets have a modular design. They consist of a basic turret from the 0.5.480.5xx series and a decentralized tool drive mounted in place of the cooling lubricant ring. The tool drive has been designed for individually switchable, axially placed tools for forwards machining. The tool drive motor drives the coupling wheel via the spur gear incorporated in the gearbox casing. The relevant tool is switched into the working position by means of the coupling. The drive motor can be located to the side opposite the...
