LASER ANNEALING

WHEN TO USE LASER ANNEALING

MEDICAL

The exact type of mark required by the medical device industry is typically called a laser annealing mark. Black Laser Annealing does not remove or engrave the material. Instead, marks left by the laser annealing machine are created by using the heat of the laser beam and bringing the work piece close to its melting point. As a result, the MOPA pulsed fiber laser annealing beam creates the desired dark oxide layers on the medical metal surface. As always, the result is highly dependent on the composition of the material and the resulting oxide. LMT can assist you with choosing the right laser annealing machine to help guide you through this process.

CUTTING TOOLS

We developed the formulas to effectively mark carbide tools with our laser engraving machine for metal without disrupting the final diameter of the cutting tool, thereby allowing the cutting tools to run in shrink fit tool holders without any run-out! Allowing laser marked carbide and HSS tools to be ran in shrink-fit tooling operations. We completed comprehensive trials to prevent any stress fracturing due to stainless steel laser marking on carbide micro tools and have been the pioneer in the marking of cutting tools with literally thousands of customers in the industry!
