The custom designed arbor slips inside the splined broach hole that we provide. This allows the customer to use the arbor in conjunction with a part that we broached, slid onto the spline, and then put into another machine and do a combination of other secondary operations. These operations include either turning the part off the arbor or doing inspection processes off the arbor by checking run out, spinning the arbor to ensure that it runs true. The secondary operations run in conjunction with the internal spline.
