SUPPLIER OF CHANGEABLE PINS FOR FACE DRIVING DEAD CHUCKS, GRINDING, GEAR CUTTING, TURNING, MILLINGG
the first cut should generally be towards the face driver to better set the workpiece and allow the drive pins to do their work by biting into it. once the first cut is made towards the face driver, then cuts toward the tailstock can be made. grinding and hard turning. a face driver has two main components, the drive head and the mounting. the mounting locates the driver in the machine with either a morse taper shank mount directly into the machine taper; or a chuck mount chucked between special chuck jaws; or a flange mount bolted to a spindle adapter on the machine spindle. the illustration shows a morse taper shank. the drive head contains the compensating medium ; which allows the pins to adjust to variations in the locating face and the spring-loaded center point
