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

Watch on YouTube

What happens here

After the spool is created with rough-sized lobes through milling, it undergoes heat treatment. Depending on the material, an 8620 core will be copper-plated before going into heat treatment for quenching and tempering to achieve the desired hardness. Tool steel spools, which are already designed for hardness, can go directly to heat treatment without plating. This process involves bringing the camshaft to a transition temperature, performing a quick quench, and then a triple temper to bring it to its final hardness.

Goal: Harden the camshaft spool to prepare it for final grinding.

Tools and materials

  • Camshaft Spool Comp Cams — The intermediate product being heat treated
  • Heat Treatment Equipment — To harden the camshaft
  • Copper Plating — To protect certain areas of 8620 steel during heat treatment

What they say

from this point the next thing happens it goes over the moorey mill over here and they go in and mill the lobes up after the lobes are milled to size for the rough size then it goes off the heat tree so if it's a 86 20 core it'll be copper plated then go to heat treat if it's tool steel it doesn't have to be plated it just goes and straight to heat treat they go and quench and temper it they bring it up to a transition temperature do a quick twin quench and then do a triple temper to bring it down
