New Laser Drill Machines Engine Components at the Molecular Level

California-based Raydiance has released a new laser micro hole drilling system capable of machining engine components at the molecular level.

The R-Drill 200, updated from the earlier R-Drill 100, is an industrial-grade femtosecond laser that generates no heat, avoiding heat dissipation problems in other forms of machining. This is possible because the laser cuts at the molecular level, vaporizing molecule by molecule to precision specification. In fact, Raydiance claims the R-Drill 200’s precision avoids the need for further chemical or mechanical rework.

The laser drill is designed for engine cylinder hole drilling. The company notes that the precision holes enable precision fuel flow and distribution, improving fuel efficiency by up to 30 percent.

“The R-Drill 200 addresses the simultaneous challenges of greater machining precision, broader flexibility in feature shape, and more cost-effective means of manufacturing the next generation of fuel injectors,” Raydiance Chief Scientist Michael Mielke told Laser Focus World. “The R-Drill 200 can be programmed to drill virtually perfect spray holes in fuel injector nozzles in less than a second per hole. The level of precision in fabricating arbitrary hole profiles is enabling a new generation of fuel injectors to direct spray patterns and droplet size distribution much more accurately to where it is needed for combustion.”
