How does CDS keep the cams from coming loose and drifting on the cam shaft?
Actually the keyway in our cam is machined to a very precise tolerance. Because of the way we control the hardening of our cams, our cams do not distort as would happen with other heat treating processes. When through harden heat treating processes are used, then it is necessary to leave more play in the keyway to account for dimensional distortion on the cam caused by heat treating. In this case, if the keyway is made too precise than the heat treating process may cause the cam to distort enough to cause the keyway and key to not join, and additional machining would be needed which is costly and time consuming. This is why most “key” type systems in use by our competitors have a wider tolerance. CDS does it differently because we use the most state of the art equipment which can control these variables. CDS has in house five axis CNC milling centers, several with dual FMS work cells, 60 pallets for parts and 600 tool magazines which machine parts or cams to any profile and to extremel
