SUPPLIER OF HARDENED CENTER PINS(POINTS) ON FACE DRIVERS FOR LIVE (DEAD) CHUCKS IN CHINA.

in fixed-center face drivers, a hydraulic or pneumatic actuator pushes the drive pins into the workpiece, whereas with spring-loaded types, the tailstock pushes the workpiece to the drive pins. in cases using a fixed center driver, you must have the right size actuator and drawbar to avoid overpowering the tailstock and to optimize the machines hydraulic pneumatic system.

the center pin located on the side of the tailstock pushes the work piece against the fixed center pin of the face driver. the motion of the drive pins against the surface of the work piece is initiated by the clamping cylinder mounted into the machine.

load and unload times with a face driver are consistently faster than using drive dogs or chucking. since the face driver self centers the workpiece, parts can be loaded in the machine and clamped in seconds. chucking takes considerably longer while the operator ensures that the part is centered and square in the chuck jaws. higher throughput, decreased downtime and increased productivity can be accomplished with face drivers.
