Riten has introduced a modified face driver specifically designed to hold workpieces with diameters of 2 inches or less. In lieu of individual drive pins, the unit features a multi-toothed drive disk that securely penetrates the face of the part. It is ideal for gear hobbing and other aggressive machining operations.
The disks are available in a choice of diameters, similar to the driving diameters on standard face drivers. The teeth configuration is designed to allow the disk to be bi-directional - for both clockwise and counter-clockwise rotation. This also compensates for the backlash common to gear hobs. The driver features three stirring screws which move the disk and center point radially to compensate for misdrilled center holes and other concentricity issues in the workpiece or machine.
The Riten Disk Driver is available in standard straight shanks and Morse tapers. Special tapers are available on request.
