Ultrafast Laser machined microholes for automotive, medicalmanufacturingHigh-precision, high-speed ultrafast Laser machiningplatforms from GF Machining Solutions’ Microlutionbrand help reduce automobile emissions and advancecoronary health.
MICROMACHININGPrecision micro-holes, smaller in diameterthan a human hair, yield exciting newproducts and enable exponential leapsin performance for existing products. Withmore precise machining solutions, microholes can be shaped to deliver fluid moreprecisely and efficiently—capabilities thatdramatically impact automotive productsand medical devices. GF MachiningSolutions’ Microlution brand pioneeredfemtosecond Lasers for industrial use.Ultrafast solutionPreviously used only for research,femtosecond Lasers today are ruggedenough to perform in a factoryenvironment. Ultrafast Lasers are prizedfor heat-free machining: Removingmaterial with no thermal damage to thepart makes it possible to create minutefeatures with extreme precision andfeature quality
Automotive partsIn automotive, new generations of gasdirect injection fuel injectors can spray fuelinto cylinders more efficiently, achievingtarget engine performance with less fueland lower emissions. Injector nozzles mustbe drilled at extremely precise dimensionsto control fuel droplet size and spraypatterns and guide fuel to a location whereit will combust with maximum efficiency.These holes, shaped at diameters of lessthan 150 microns, must have near-perfectsurface quality. To be cost-effective, eachhole must be drilled in a few seconds orless with a repeatable process—far beyondtraditional drilling technologies’ capabilities.Laser drilling’s non-contact processproduces no tool wear, dramaticallyreducing part variability and helpingautomakers worldwide create the mostefficient injectors.Medical devicesCatheters for cardiac ablation to treatarrhythmia is another area where thismachining technology enables safer, moreeffective medical devices. Increasinglycommon, ablation employs a catheter withan electronic tip that is guided to the heart tocauterize the source of the harmful signals.
Newer ablation catheter tips use irrigationto flush saline solution around orthrough the tip, cooling the area enoughfor successful ablation. Ultrafast Lasermicromachining produces more preciseirrigation catheter tips, delivering morecoolant from less fluid, reducing the risksof boiling. To manipulate liquid dispersion,catheter tip holes are drilled to exactgeometries, an economically unfeasibletask with traditional machining technology.Pioneering solutionsMicrolution has developed systems formultiple industries and now offers a varietyof ultrafast Laser machining platforms:- a stand-alone Laser machining station;- a dual-station (hybrid) machine witha mechanical mill to rough out largerfeatures and an ultrafast Laser to finishthe surface and edges; and- a dual-station (measurement)machine which performs detailed partmeasurement in parallel to the ultrafastLaser machining process.
