Tecnologie FRB Face Drivers as used on Lathes, Cylindrical Grinding Machines and Gear Hobbing Machines for example work by a patented compensating system, operated by a wedge lever which allows four-pin driving. This system is highly adjustable and ensures a safe and relaible torque transmission under the most difficult of conditions such as rough surfaces or driving on faces not square to the diameter and rotation axis by as musch as 3mm.
On each pass it is possible to remove up to 15mm of material (in diameter) at a feed rate of 0.7mm/rev.
The centre point is independent of the driving pins and rests against a belleville spring washer assembly inside the shank. Even with varying centre sizes, work positioning is maintained with optimal repeatability. The centre point can be easily removed with no need to remove the face driver from the machine tool.
