Riten Industries, a manufacturer of face drivers, has published detailed User Guides for its mechanical and hydraulic styles. The documents explain appropriate applications for each style, model selection, sizing guidelines relative to the workpiece, mounting and installation instructions, and proper care and maintenance. With a face driver, the entire workpiece is exposed for machining. Since a face driver locates on the end face of the shaft, it is possible to machine the entire length of the work piece in one operation. The single axis reference point established by the center point of the face driver allows for a high degree of accuracy. In comparison, traditional machining with chucks requires multiple operations as the part is reversed to turn or grind both ends. Riten claims that by eliminating operations and setups the use of a face driver reduces costs, increases productivity and produces a part with a higher degree of accuracy.
