What is a Laser Cutter and How Does it Work?

Laser cutting technology is mostly used in the manufacturing sectors by engineers and designers although this is becoming increasingly popular amongst small businesses, schools and hobbyists alike. Laser cutters have a lot of benefits and applications and in this article, I would be talking about what a laser cutter is and how it does work.

What is Laser Cutting?

Laser Cutting is the process whereby a laser beam is used for cutting and piercing through materials so as to cut out complex shapes, patterns, and geometries that have been specified by designers. The materials that can be cut using a laser cutter range from light materials like clothes, paper, and wood to tougher ones such as metals and gemstones. Laser cutters help to deliver an accurate and smooth finish due to the high level of control that it offers.Click here.

Types of Laser Cutters

There are three main types of laser cutters; fiber laser cutters, CO2 laser cutters, and the crystal laser cutters.

Fiber Laser Cutter

Fiber lasers belong to the solid state group and are made from “seed laser” which is amplified using special pump diodes and glass fibers. These lasers are mostly employed in the laser marking processes. They can be used to cut both metal and non-metal materials such as plastics and metals. Fiber lasers are cheaper to maintain and they tend to last longer compared to other types.

CO2 Lasers

This type of laser is the most commonly used of the three types of lasers that we have, this is due to the fact that they are relatively inexpensive and they can be used to cut a wide variety of materials.

Crystal Laser Cutters

There are two types of lasers used in this process; the neodymium-doped yttrium aluminum garnet (nd: YAG) and the neodymium-doped yttrium ortho-vanadate (nd: YVO). These crystals have a wavelength of about 1.064mm which makes them suitable to cut both metals and non-metals. Crystal laser cutters are costly to maintain as they are made from expensive pump diodes which cost a lot to replace.

How Does a Laser Cutter Work?

Laser cutters can cut metal with high temperatures and make complex shapes but how do these lasers work exactly? Well, it starts with the use of two mirrors; a gain medium and a light source. Light enters the gain medium and excites the atoms inside to a higher state, after a while the atom would drop back down to the original state to emit a photon. The photon then creates a chain reaction which makes the other excited atoms emit their photons; soon we have a bunch of photons bouncing back and forth between these two layers. Since when the mirrors do not have a reflectivity of 100% some of the photons will pass through and create a laser. Now, that is a general concept of how lasers work.

Laser cutting is a very reliable and accurate cutting process and its benefits cannot be overemphasized. Laser cutters can cut precise shapes into metal with the use of laser beam machining in ways the traditional machining processes cannot that’s the beauty of lasers.…

How to correctly install CO2 laser engraving and cutting machine?

This is a key point: the CO2 laser machine will work well only if you install the CO2 laser engraving and cutting machine correctly. Do not worry; this article will help you to know the correct installation process of the CO2 laser engraving and cutting machine. Let’s go with the following steps to install a CO2 laser machine:

Step 1

Remove the whole package; recover the machine such as wood, plastic film, etc. Be careful with of the nails.

Step 2

Now open the front door, the side door and remove all additional parts of the machine, such as water cooler, dust collector, air pump, laser tube, rotary etc. Please cut the tie on the X-axis belt and Y axis after opening the front door, get the CD and then move the laser head to the center of the work area by hand.

Step 3

The most vital step to install correctly a CO2 laser machine is to install the CO2 laser tube. Remove the laser tube from the package leisurely, and then put it in the socket of the laser tube on the back of the machine. If the laser tube has a protective plastic cover, cover the protective tape. If not, please cover enough waterproof tape. In the laser light, there is water behind the high-pressure end is water.

Step 4

Water cooler installation:  connect the water inlet and the water outlet of the water cooler with the water outlet and the water inlet of the machine by means of the silicone tube and then connect the air plugs.

Step 5

Installation of the air pump: connect the air outlet of the air pump with the air inlet of the laser cutting.

Step 6

The method of installation of the dust collector: connect the tire port of the dust collector with the telescopic tube of the laser machine.

Step 7

The installation of the floor: connect the security of the floor, find a cable and you must connect the machine to the floor. The other end connects the steel bar; it should be buried under the ground 1.5 meters. If it is in the humid place, the depth of the burial can be shallow.

Step 8

CO2 laser cutter should use the power with the 220V. If your local power is 220V, you can directly connect it. If not, you require an additional power transformer for the machine to change the power.

Step 9

First, supply power to the water cooler. Then check the silicone tube to see whether it can produce water, especially if the water flow is normal.

Step 10

Turn on the power: connect the 220V power to the laser power and open the emergency stop, then the power is blocked to see if the power is normal. Press ESC twice and then press up-down-right-left on the Leetro control panel to see if the laser head can move usually.

Step 11

Connect the softdog to the computer, copy the data from the CD to the computer, use the data cable to connect the computer with the red card, and then install the software properly.

Step 12

Open the Lasercut icon on the desktop of the computer, and design a circle of approximately 40*40 mm, the processing method is cutting, the speed is 100, the power is 1 and then downloads in the machine. Move the laser head to the right place, then press “test” to see if the laser head can surround the edge. Whether it is normal, press “start” and start working.

I hope that the above steps can help eliminate your confusion about the installation of the CO2 laser engraving and cutting machine.

Activities to do on a Rainy Day

How to perfect your pick up lines

Using pick up lines can be fairly hit or miss when attempting to flirt with someone of either gender, no matter how slick you think you may be. There are a few rules to remember and tricks to try when deciding to employ a pick up line to increase your chances of success and reduce the risk of embarrassment.

It’s Best to Try the Honest Approach.

Instead of a pick up line, just try the honest approach. Most people respond much better to a simple “Hi, my name is _______, what’s your name?” than they do a cheesy, overused pick up line. It may seem counter intuitive, but the direct and straightforward approach is the best one, over all, and it makes you seem like less of a creep. Don’t you want to start out on a good foot instead of falling flat on your face with a pick up line that he or she may have heard a million times before? First impressions matter a lot, especially if you’re trying to meet a new romantic partner, and you only get one chance to make a good one so make it count. This could be a story you tell to your kids down the line and a funny pick up line may not be the wisdom you wish to impart on your future generations. Also, according to psychology, “trait perception” plays a large role in those first interactions. Since we are not able to see a list of traits from the people we interact with, you are forced to infer them from the actions the other person takes. Coming at somebody with a cheesy pick up line like “Do you wash your pants in Windex? Cause I can see myself in them” says more about you than you think it does… and not in any good way. See more.

If you are looking for a calling a laser company to investigate the quality of their laser cutters than you may think of a good line for getting the truth about their machines and support.  Check out Boss Laser reviews here.

Try the flattering approach.

If you want to use a pick up line, try just starting with something flattering. Be careful, though. There’s a thin line between sounding like a creep and saying something genuinely flattering. Try to stay away from anything too physical or personal. An exception to that is complimenting his or her smile, if they are in fact smiling. It’s best to stick to flattering his or her choice of drink or an item of clothing (think more shirt and less pants). Make sure that they know you are approaching them as a person and not as a body. Some pick up lines tend to sound like you’re only interested in getting to know their body and not the whole person and can be a huge turnoff. Approach someone genuinely and compliment them on something that sticks out. Don’t try too hard… people can see right through that and you come off as aggressive or a fraud.

Remember, pick up lines can be fun if you use them intelligently. A good pick up line is one that is genuine, funny and direct without being creepy or reducing the person to a body part. See more this site:  http://www.rainydaysandpajamas.com/cant-go-outside-to-play-no-problem/.

Can't Go Outside to Play? No Problem!

Can’t Go Outside to Play? No Problem!

It doesn’t matter if you’re a child or adult when it’s pouring the rain, it’s a nightmare! Outdoors people might love the rain but sometimes it’s far too cold and wet to go out which means you’re stuck indoors! For most, they would be happy enough to sit in front of the TV and watch a movie for a few hours to pass away the time or to sit on the computer but for some, they want to do something a little more productive! So, what can you do indoors when it’s raining?!  You can click here for a few ideas or keep reading…

Why Not Set-Up A Play Room Indoors?

Have a spare room at home? If you do, why not create your own little play room? You can set up the sofas and chairs like a fort and play dragons and knights where the knight has to defeat the dragon. Children will love this and if you’re in charge of the kids for a little while and it’s raining, this will keep them preoccupied! Remember, it’s difficult to find something entertaining for the children when it’s raining outdoors and can’t get outside to play. However, by setting up a little play room indoors, you can ensure they have something to do and prevent them getting tired and cranky.

Write a Play Indoors

It doesn’t matter if you’re in charge of five year olds or teens, they will always be bored when it’s raining. For some reason, kids seem to want to go outdoors more so when it’s raining than when it’s sunny so you have to keep them entertained. One simple option would be to write a very short, basic play that gets all children (and adults) involved! This would be a fantastic way to ensure the children aren’t just sitting in front of the television for hours and it might just keep the peace too! Why not write something that the children will enjoy? It’s fun and not too hard to do.

Rearrange and De-Clutter

OK, so de-cluttering your room won’t sound like the most appealing or fun activity of the day but it can be a real eye-opener. If you go through some of your drawer and empty them you will find a tone of things you forgot you had. For instance, you could have forgotten about old photos that have been stuffed away in the back of a drawer for a few years or a special gift you thought you lost. There are so many things to find when you’re de-cluttering and rearranging things and for the most part, you will be very surprised indeed. Kids might not find this appealing but adults will and it’s great if you find yourself at a total loss! for more details, visit : http://www.nrcc.cornell.edu/services/blog/2009/08/28_summer_rain/index.html
