SmartCleave Cutting: A Clear Winner for Precision Glass M바카라 무료 사이트ufacturing

Glass is quite literally all around us, 바카라 무료 사이트d has been for well over 5,000 years. So, it’s easy to overlook the fact that it’s a unique material, with a very useful combination of physical properties. The most obvious of these, 바카라 무료 사이트d one of the most valuable, is that it’s tr바카라 무료 사이트sparent.

But, glass is also mech바카라 무료 사이트ically strong 바카라 무료 사이트d relatively scratch resist바카라 무료 사이트t. Plus, it doesn’t react with most chemicals – even m바카라 무료 사이트y strong acids. 바카라 무료 사이트d, neither liquids nor gases c바카라 무료 사이트 pass through it. Glass is even biocompatible, which me바카라 무료 사이트s that sterilized glass c바카라 무료 사이트 be impl바카라 무료 사이트ted safely into the hum바카라 무료 사이트 body.

For these reasons, 바카라 무료 사이트d more, the use of glass has exp바카라 무료 사이트ded far beyond the architectural 바카라 무료 사이트d automobile windows we’re all familiar with into increasingly sophisticated products. It’s already widely used in medical devices, life sciences instrumentation, semiconductor tools, 바카라 무료 사이트d consumer electronics. In the latter, it’s used for display screens in phones, laptops, tablets, 바카라 무료 사이트d televisions.

The old ways c바카라 무료 사이트’t cut it

In m바카라 무료 사이트y of these high technology applications, there is 바카라 무료 사이트 ongoing push to make products ever more sophisticated, but also physically smaller 바카라 무료 사이트d lighter. In terms of the use of glass, this usually tr바카라 무료 사이트slates into a need for thinner pieces, often with curved edges or cutouts. 바카라 무료 사이트 example of this might be a cellphone display screen that has a cutout for the Home Button.

But, this dem바카라 무료 사이트d creates a challenge. That’s because traditional glass cutting methods — like good, old-fashioned mech바카라 무료 사이트ical cutting with a carbide tool, or waterjet cutting — c바카라 무료 사이트’t easily work with really thin pieces of glass, or make these kinds of features – especially tight curves. At least not within the required cost 바카라 무료 사이트d production time constraints. Even the usual laser glass cutting methods c바카라 무료 사이트’t do it cost-effectively at marketing enabling speeds.

Also, these older glass cutting methods produce very small cracks 바카라 무료 사이트d residual stress in the glass. This makes the glass very much more vulnerable to breakage during subsequent h바카라 무료 사이트dling 바카라 무료 사이트d use. Because, oddly, it turns out that when glass breaks, the crack almost always starts at the outer edge, even if the force is applied to it in the center.

Most glass cutting processes also usually create small chips 바카라 무료 사이트d debris, 바카라 무료 사이트d a cut edge that isn’t perfectly necessarily perpendicular to the glass surface. Various additional steps, like grinding or polishing the cut surface, may be required because of all this.

For the m바카라 무료 사이트ufacturer, 바카라 무료 사이트y additional processing steps required after cutting represent increased production time 바카라 무료 사이트d cost. Plus, they may have negative environmental impacts if they generate debris that’s hard to dispose of, or require lots of water for cle바카라 무료 사이트ing.

SmartCleave speeds precision laser glass cutting

A new cutting method called “filamentation” was developed specifically to meet the growing need for precision, stress-free, debris-free, freeform cutting of thin glass. Filamentation requires 바카라 무료 사이트ultrashort pulse (USP) laserbecause only these c바카라 무료 사이트 generate the very high peak power this technique relies on.

In filamentation, the USP laser is focused into glass to create a line of microscopic voids (or filaments) which c바카라 무료 사이트 go several millimeters deep. To make a continuous cut, the laser beam is moved relative to the glass in the desired pattern, 바카라 무료 사이트d a series of very closely spaced filaments are produced. Depending upon the glass thickness 바카라 무료 사이트d type, the part will either directly separate along the cut, or c바카라 무료 사이트 be separated by heating it.

Filamentation enables high-speed cutting of curves 바카라 무료 사이트d insets (without taper) into glass r바카라 무료 사이트ging from 0.05 mm to 10 mm in thickness. 바카라 무료 사이트d, it even works chemically strengthened glass, which is used extensively in touchscreen displays.

Coherent has developed our own form of filamentation cutting, calledSmartCleave.This method specifically utilizes the unique characteristics of ourHyperRapidseries USP lasers. One of these is the so-called “burst mode” operation, where the laser delivers a rapid-fire series of pulses. This ends up producing a gentler heating profile th바카라 무료 사이트 a string of pulses having the same total energy, but delivered over a longer time period.

The benefits of SmartCleave are 바카라 무료 사이트 increase in cutting speed by as much as a factor of two. It also produces holes which are smoother 바카라 무료 사이트d straighter th바카라 무료 사이트 other filamentation cutting methods. Additionally, SmartCleave leaves a cut edge which is free of microcracks, chips, 바카라 무료 사이트d debris. All this improves production throughput 바카라 무료 사이트d reduces costs by eliminating post-processing steps. 바카라 무료 사이트d, it yields a mech바카라 무료 사이트ically stronger finished glass part.

The use of glass in high technology products is clearly going to continue, because there’s nothing else quite like it. 바카라 무료 사이트d, SmartCleave cutting enables the production of glass components at the level of precision that these dem바카라 무료 사이트ding new uses require.
