face driver drive pins, changeable pins, drive blade pins, lathe blade pins, driver key pins
the face driver can help improve machining accuracy, reduce setup time, and increase productivity by allowing for faster and more efficient machining operations. there are two factors to consider when choosing driving pins: pin direction and driving diameter. both are stated in the second and third columns of this table. when choosing a center point make sure the center hole diameter of your workpiece falls within the required range in this table.
with face driver, the entire workpiece is exposed for machining. therefore, you are able to machine the entire length of the workpiece in one operation. the elimination of a setup in the production process results in increased accuracy and efficiency. furthermore, the single axis reference point established by the center point of the face driver allows for a higher concentricity.
