While 3D laser deposition is a newer addition to the moldmaking toolbox, ablation is still the standard application for lasers when it comes to finishing cavities. Many types of lasers can be used to impart textures, but Raydiance Inc., Petaluma, Calif., offers what it says are complete machining solutions involving ultrashort-pulse lasers.
“Usually when folks turn to femtosecond lasers, they’ve tried other tools, maybe even other lasers, but can’t reach the dimensional precision they need,” said Michael Mielke, chief scientist for Raydiance. “We deal with part-to-part consistency on the order of 1µm.” » READ MORE
R-Mill for design and production of micro features in medical device designs.
Medical device designers and process engineers turn to Raydiance solutions to create micron-scale, complex features in medically relevant materials. The R-Mill enables highly specialized, non-contact processing of pericardial tissue for heart valve replacements, resurfacing of catheter balloons to create micron-scale uniformity, and precision placement of slots and grooves in microfluidic applications. Milling pericardial tissue on an athermal basis leaves material mechanically flexible, while creating a smooth transition between plains. » READ MORE
Ready to integrate into customer manufacturing lines, the new solutions increase yield and improve production efficiency by optimizing factory workflow to eliminate expensive post-processing steps and achieve part-to-part consistency. R-Drill, R-Tube and R-Mill combine Raydiance's femtosecond laser technology with the company's materials processing expertise and application-specific software. Deployed in factories of Fortune 500 companies worldwide, the Raydiance solutions typically reduce cost per part by 20 percent to 50 percent. » READ MORE
Known as R-Drill, the solution employs a femtosecond (1 x 10 to 15 seconds) laser pulse that prevents the hole surface from being damaged during the machining process. Because the resulting spray hole is smoother, the fuel injector provides better atomization of the fuel spray, which in turn creates more efficient combustion in the engine’s cylinders. Engineers from Raydiance, maker of the R-Drill, estimate that it could boost the fuel efficiency of engines by as much as 20% to 30%.
Mielke said that heat typically diffuses in metals within a few picoseconds (10 to 12 seconds). Therefore, by operating lasers in the femtosecond range, there’s not enough time for thermal damage to occur. Raydiance claims that because its technique creates a smoother surface than other machining processes -- such as nanosecond lasers, electrical discharge machining (EDM), and mechanical drilling -- no post-processing is required to clean the surface. As a result, the new technique eliminates a step from the manufacturing process. » READ MORE
R-Drill, R-Tube and R-Mill combine Raydiance’s femtosecond laser technology with the company’s materials processing expertise and application-specific software. Customer applications include precision nozzles for automotive engine fuel injectors, cooling micro holes for power generation turbine blades, texture surfacing for biomedical implants (e.g. knee, hip and ear), and cutting of peripheral and cardiovascular stents.
All Raydiance solutions increase factory output with compact, industrial grade, all-laser manufacturing solutions that enable high levels of automation; eliminate heat-affected zone (HAZ) damage to parts that require expensive post processing; reduce or eliminate internal process development using pre-loaded Raydiance designed processing instructions for the laser and material handling workstations; and speed application development and time-to-market with 24-hour print-to-part software. » READ MORE
“The world of micromachining is constrained by the quality and economic realities of traditional methods,” said Richard Pierce, Raydiance CEO. “With the R-Drill, R-Tube and R-Mill, Raydiance eliminates these constraints and enables new product innovations with substantially higher quality and lower cost.”
According to Raydiance, the solutions enable a shift in product design and development by reducing prototyping and production transfer from months to as little as 24 hours.
