Comp Cams Factory Tour: How Does a Performance Camshaft Get Made?

What happens here

After burnishing, camshafts are individually placed on a belt polisher to achieve their final, mirror-like finish. While the burnishing process smooths the overall lobe surface, the belt polisher refines the journal surfaces to a high degree, ensuring extremely low friction for rotation within the engine. This meticulous step contributes significantly to the camshaft's performance and longevity.

Goal: Apply a final polish to the camshaft journals for low friction.

the belt polisher over here that doesn't get msc yeah the the steady rest will leave a little line on the girdle so jackson will come over here and make sure that see this this real small line here yeah this is that carbide foot on the steady rest on that akuma grinder so you send it out looking like this people get mad jackson's job is to make people not mad yep quality chance yeah and so he does a great job with this the other thing that he does is like i said when it when the cam runs to the msc if there's any fault in the grinding like the dress was bad or anything like that when he takes it out he's going to look at it really good and he'll be able to tell the light will catch it differently and you'll be able to see things visually that you can almost can't pick out with anything other than prophylope so he's really the last step for quality before they go and get packaged is it cool knowing that your eye is more valuable than an expensive machine yeah it's really something i mean you gotta you gotta you gotta really care about what you're doing if you didn't care you you wouldn't catch it nice it's awesome that's cool and what this machine basically doing is like we did the plateau home to make the surface smoother on top to have more load bearing area for those valleys to hold oil from home this is basically plateau honing that can finish to make it have more load-bearing area that's right it's a good way to think about it when you know the thing is is when when every time that serial number is done like we know like if kenny arendelle ground it we know who ground it we know who picked the core who straightened it who ground it who checked it in qc and then jackson will put his name on it so you know when you think about it buying a camshaft from comp cam you're getting a signature camshaft because everybody through here that touch the cam put their name on the report to say that it was going through the system it's a pretty neat deal that is neat if you've seen those other videos yet
