And another thing, CNC stuff is not as strong as a forged part. Metals have a grain stucture, kind of like wood. A forged part has had its grain realigned in the forging/shaping process. A CNC part may be cut out with its grain structure in a less than ideal direction, say, going across the width of a crank rather than down its length. Some companies use cold forged blanks and then use CNC to finish the job. This gives you a strong part at a lighter weight. I believe Race Face does this on their turbine cranks. Or if you watch one of Discoverys chopper shows you will see them use a forged wheel blank,for strength, to start the CNC process, while they would CNC a cylinder head out of blank stock because strength is not a critical factor.
