I don't see how it can be. The holes for the pins can be easily drilled out, but how can they separate the two parts? I suspect the machining of this job was programmed up as a demonstration of what the machine can do, and some guy with a sense of humour put a fake universal joint in to make us watch to the end.

@Trottelheimer Well, the machine shown probably cost $500,000 or more. 5-axis machines sell for up to $1,000,000. If you make machines, you have to show potential customers what they can do. There is no evidence the billet was specially cast. They probably just went to a local steel supplier and bought an off cut from some heavy rod to demonstrate the machine with. When the demo was done, they threw it away. My local steel supplier has a cutting service and can supply such a large diameter round bar for less than $200. What weird 4-cylinder engine has a universal joint right on the crankshaft? Universal joints are standard range parts like bolts, nuts, and bearings. Made by the million on special machines for a unit cost well below the cost of using a CNC machining centre.
