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.
