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

What happens here

Modern CNC (Computer Numerical Control) grinders, like the Okuma machines, represent the next generation of camshaft manufacturing. Unlike their manual predecessors, these machines are fully automated and controlled numerically, eliminating manual operator input during the grinding process. They utilize a high volume of coolant (up to 50 gallons per minute) and operate at much higher RPMs (3000-5000 RPM) compared to older machines. This dramatically increases efficiency, allowing one CNC machine to produce a camshaft in about 15-20 minutes, compared to 6-8 per day on manual grinders. These machines are significantly more expensive but offer superior control and precision, leading to better quality camshafts.

Goal: Understand the advanced capabilities and benefits of modern CNC camshaft grinders.

Tools and materials

  • Camshaft — The item being ground
  • Okuma CNC Grinder Okuma — Automated precision grinding of camshafts
  • Coolant — Cooling and lubricating the grinding process

patients to do it right every time so that kind of moved us into a different era um starting in the early 2000s we started to get these grinders over here let me run you over here really these big six-inch pipes there's a thousand gallons per minute of coolant going through these pipes at um 80 psi so when these pipes breaks it looks like a flood that happened before no those are all schedule agents so these are the machines that are the next generation so if you go over here and look at this setup so instead of all the handles on it everything's controlled with the american controller the grinding wheel instead being a conventional piece now is a cbm piece this this grinder will run 50 gallons per minute of coolant through it so instead of watching it take material off now all you see is like niagara falls yeah for 50 gallons per minute you can almost water speed out of what's coming out of it yeah you can't even see anything going on in there but what's neat is if you can go over here and put your ear to it you can actually because your aircraft you actually hear the materials coming off of it as it goes around you you're kind of yeah so it lines up where you're actually watching it here you can see like this grinding wheel is going 3000 you know 160 rpm and it also shows you how well balanced it is too so we can measure things on this and do things you know that machine we could never go never to put 50 gallons per minute you know cool to it we never could have gone 3000 rpm we couldn't control things as well so what's the turnaround time how many cans can one of these make in a day this will make a good camshaft in about 15 minutes it's a little more than a minute to load so let's say 20 minutes so instead of instead of six or eight a day you know we're going you know three an hour wow yeah so it's amazing the other thing you do is if you see my friend over here so kenny and i have known each other forever kenny's actually the first employee that cockham's ever hired so when rhs decided they were going to grind camshafts and everything they were going to form compounds you know you start looking at and go well what do we need to hire well we probably ought to hire somebody who can grind cans so before comp you were at cam dynamics and so you've been here for 40 years 46 years about taking any shoes off or anything um so kenny's been here for 46 years now when we were grinding everything on those manual machines like kenny did every pro stocks cam for…
