Heavy Steel Gear Teeth Laser Cleaning

We verify gear tooth geometry is preserved by tracking surface temperature throughout the job and running a profilometry check after cleaning. On heavy steel gear sets, a full cleaning typically takes 15–20 minutes per tooth pass — compared to 45–60 minutes for a manual degrease-and-blast cycle. The result is bare, oxide-free steel with no media contamination in the root valleys.

Laser cleaning is faster and safer for precision gear geometry than blasting or chemical methods. A typical industrial gear set takes 15–20 minutes per pass with laser versus 45–60 minutes with a degrease-and-blast cycle — and unlike blasting, laser cleaning won't round off tooth edges or leave media packed in root valleys. No chemical waste to dispose of either, which matters on large gear jobs.

Laser cleaning removes rust, grease, and old coatings from gear teeth in one to two passes without touching the steel underneath. We regularly clean gear sets with 10–20 years of built-up lubricant residue and oxide scale — the tooth profile comes out bare and ready for inspection or recoating, with no media contamination in the tight spaces between teeth.

The most important variables are how many passes we run and how fast we move across the tooth face. For heavy rust and grease, two slow passes typically clean down to bare steel without heating the part enough to affect hardness. Most gear sets are done in under 30 minutes total — fast enough that the gear stays cool to the touch throughout the job.
