Laser Plastic Cutting

Laser-aided cutting has brought about a revolution in the manufacturing industries. These high-powered optical beams are used to cut through a variety of materials such as metal, wood, glass and plastic. The laser is directed at the required surface and moved around to cut the material in the desired shape. Laser cutting gives a finer finish to the end product as compared to conventional cutting methods.

A typical laser beam is about 1/5th of a millimeter in width and has an intensity of 1000 to 2000 watts. Most laser cutting machines are integrated into a CAD/CAM system that helps the user design the end product on a computer before implementing it on the work piece.

Laser cutting devices are proving beneficial in a wide array of industries. The plastic industry is no exception. These optic powered devices are used to cut precise shapes into plastic or acrylic sheets. The lasers can be used to cut plastics of varying thickness by simply altering the intensity of the beam. Lasers are not only used to cut through plastics but also help engrave on various surfaces.

Laser plastic cutting machines bring precision and accuracy to the entire process. Since most machines are fully automated, they can perform complex cutting operations at high-speeds. The laser plastic cutting machines can also be used to cut polymers, polycarbonates and other synthetic materials such as polyesters and rubbers.

The laser cutting method uses a non-contact approach when cutting the material. Due to this, the wear and tear associated with conventional methods is absent, preventing the product from any damage and deformation. The laser process also delivers a finish quality unmatched by any other process.

When using laser plastic cutting machines, care should be taken to avoid the use of flammable plastics such as PVCs. These materials cannot cope with the heat generated by the laser and get damaged easily.

Laser Glass Cutting

Laser cutting is a precision cutting method widely used in industrial manufacturing. Laser cutting allows a level of accuracy unmatched by any other cutting method. A high-powered laser is directed at the material to be cut. The material burns, melts or vaporizes, leaving a high quality finish.

Apart from the common materials such as wood, plastic and metal, laser cutting is also widely used in the processing of glass. Glass has become an important component of a large number of applications. Its use is not just restricted to windows and bottles but has expanded to telecommunications and information technology. These modern applications require a higher level of accuracy and precision that cannot be matched by traditional methods.

Traditional glass cutting methods make direct contact with the surface, increasing chances of unwanted scratches and abrasions. Moreover, material losses and glass dust are other problems faced in the conventional process.

The use of lasers has revolutionized the art of glass cutting. The laser beam is used to produce highly complex and accurate shapes with a fine edge finish. The power of the laser beam ranges between 1000 to 2000 watts. Most laser cutters are integrated into an enclosed machine with state-of-the-art software. Since the laser used is a "class 4" laser, care is taken to keep the user away from direct contact. The CO2 laser is the most common device used in glass cutting.

The advantages of laser cut glass are many. Apart from the superb quality edges, flaking, chipping and micro-cracks are almost completely eliminated. Moreover, laser cut glass is up to 3 times more durable than conventional cut glass. Since cutting oil is not used in the process, the glass washing process is also minimized.

Laser glass cutters can be used to cut glass of any thickness with an equal amount of accuracy. From decorative articles and frames to quartz crystal oscillators and display glasses, the use of these devices is limitless.

Laser Wood Cutting

Ever since its introduction in the mid 1900's the laser has come a long way. From light shows to scientific experiments, this optical phenomenon has been used in a variety of avenues. Today, lasers are being used in the manufacture process as cutting equipment.

Laser cutting devices direct a high-powered laser beam at the required surface. This makes the surface burn, melt or vaporize, giving the end product a high quality finish. Laser cutting is used on a variety of surfaces such as plastic, glass, metal and so on. Wood is another popular surface for laser cutting.

Most laser cutters are powered by CO2. Wood has a high absorption of the 10.6-micron wavelength of CO2. The cutting takes place as a result of a chemical degradation process, where wood fiber is burned away and removed under the pressure of an assist gas. Due to this, the edges of wood articles cut by the laser process appear charred, but there is negligible surface discoloration.

There are several factors that influence the ability of a laser to cut wood. Firstly, the characteristic of the laser beam should be taken into consideration. These include power, mode, polarization and stability. Usually, lasers used for cutting wood range between 200 to 800 watts. However, depending on the application and the intricacy of work, the beam density maybe varied. The equipment and processing variables such as the design of the beam, the feed speed and the type of gas used also greatly affect the wood cutting process. Lastly, the properties of the work piece also affect the efficiency of the laser cutting process. For example, dry lightweight woods are easy to cut, while dense moisture laden woods require more effort.

The laser cutting process scores several advantages over the conventional wood cutting methods. The traditional saw cutting method cannot match the level of accuracy and intricacy achieved by laser cutting. Moreover, the durability of the end product is greater and wastage of materials is minimized. However, with each machine accompanied by a cost of several thousand dollars, it is not an affordable option for everyone.

Laser Cutting

Laser cutting is a technology that uses a laser in cutting different kinds of materials, mostly metals such as carbon steel, aluminum, stainless steel and copper alloys. It is widely used in the metal fabrication industry to increase cutting speed and cutting capacity, reduce production costs, increase productivity and improve cutting quality.

A laser or LASER (Light Amplification by Stimulated Emission of Radiation) is a device that generates a highly concentrated monochromatic and coherent beam of light. The light is produced through the process of stimulated emission.

Among the most commonly used laser in cutting is the carbon dioxide laser (CO2 laser), a kind of gas laser that is also used in welding. It is capable of emitting a maximum of 100 kilowatts at 9.6 µm and 10.6 µm and of cutting 20-30 m of one millimeter-thick material in a minute.

Cutting is done by aiming the energy produced by the high-power laser at a small portion of the object to be cut. That small portion is pierced first before a cut is made.

From the small hole, a cut is created either by moving the beam across the area of the material being cut, or by moving the object while the laser is kept still. One can employ both methods. As the intense beam of light strikes the part of the object or material, the latter?s temperature rises, causing it to melt, burn and evaporate even without sufficient amount of heat.

Not all materials require the same amount of laser power (the rate at which energy is delivered by the light). Thicker materials need more laser power while thinner ones need lesser laser power. Usually, carbon dioxide laser cutting is done with 1,000 to 1,500 watts. Materials such as steel need more than two kW.

Compared to other metal cutting procedures, laser cutting is far more advantageous, although it has some disadvantages, too. Its primary advantages are precision, cutting quality, cutting speed and economy. Among its disadvantages is its high voltage requirement. There is also risk of getting serious burns from the laser beam.

Industrial Laser Cutting

Over time, the use of lasers for various types of cutting jobs has increased several times over. Today, laser cutting instruments and systems are being used in many types of industrial laser cutting jobs.

Industrial laser cutting is popular with various precious metal cutting industries, as it allows the precious metal to be cut with high precision. This process results in minimal wastage of precious metals. The precise cut also ensures quality work.

Industrial laser cutting has gained popularity because of its many benefits. Both small and large parts can be cut at reasonable cutting speeds while maintaining very high quality standards. The cutting can be done without the need for repeated passes. The laser cutting width can also be kept at a minimum, even as little as 20 microns in fine sheet material. This ensures very small radii and results in excellent and crisp cutting, even in the smallest of instruments or components.

Lasers also have high repetition rates and high speed. This means that they have an excellent edge over any other cutting method. Good quality and high speed is a combination that makes good commercial sense. Also, the edges cut by lasers have minimum burr, which means that there is hardly any post-processing work required. Besides this, the laser can also be personalized to suit industrial cutting needs.

Apart from this, industrial laser cutting also involves engraving on various systems. This means that industrial laser cutting can also be used for designing purposes.

Most industrial laser cutting involves the cutting of plastic, wood, and metal. However, with the use of lasers growing by the day, industrial laser cutting is seeing many new applications being introduced every day. It is also advisable for any industry that uses other cutting instruments, to shift to industrial laser cutters because of the ease, convenience, and versatility that they offer.

Experience Cutting Edge Technology With Laser Equipment

It has been twenty years now since laser was first used to make signage and similar products. In this huge time frame, sign makers and other professionals have found new and varied usage of the laser technology to provide better products and services to their customers.

In comparison to mechanical cutting, laser cutting and engraving has evolved to become a technology that is a level above the rest. Laser cutting works by directing the output of a high power laser, by computer, at the material to be cut leaving an edge with a high quality surface finish. Laser cutting is mostly used for metals such as carbon steel, aluminum, stainless steel and copper alloys. It is widely used in the metal fabrication industry to increase cutting speed and cutting capacity, reduce production costs, increase productivity and improve cutting quality. Its primary advantages are precision, cutting quality, cutting speed and economy.

Laser cutting include easier work holding and reduced contamination of work piece. It provides greater levels of precision since the laser beam does not wear during the process. Moreover some materials are also very difficult or impossible to cut by more traditional means thus in that case laser cutting is the best option available to work things out. A mechanical cutter can only cut detail as fine as the diameter of the smallest available tool. A laser cutter by contrast can cut to the width of the laser beam, measured in hundredths of a millimeter. Mechanical cutting leaves a rougher edge finish to the cut surface than laser cutting, which need additional operations to achieve the standard of finish achieved with a laser. It leaves a polished, finished edge requiring no further work.

Alike laser cutting, laser engraving is the practice of using lasers to engrave or mark an object. As the laser moves it removes tiny dots of material. The image is usually built line by line, similar to the way an ink-jet printer works. The technique can be very technical and complex, and often a computer system is used to drive the movements of the laser head. Despite this complexity, very precise and clean engravings can be achieved at a high rate. Laser engraving can be performed on a wide variety of substrates starting from acrylic, glass, crystal, marble, granite, stone, metal, plastic, wood and even stamping material. Laser engraving is required in many different applications including jewelry and industrial purposes. Laser engraving is highly accurate as it is computer controlled. So the biggest leap in the laser technology is the interface of the laser equipments with the normal computer which makes laser equipments more simple and easy to operate.

Laser Cutting Systems

Laser cutting systems are quite in demand for normal and high quality laser cutting of various substances?from fabric to metal. Depending on the need for laser cutting, there are different types of laser cutting systems. These are high speed cylindrical laser cutting systems, CO2 laser cutting systems, ion lasers, diode lasers, fiber lasers, etc.

Ion lasers stimulate the emission of radiation between two levels of ionized gas providing moderate to high continuous-wave output of around 1mW to 10W. Carbon dioxide lasers, on the other hand, use the energy-state transitions that exist between the vibrational and rotational state of the CO2 molecule to emit radiation that is of 10 µm, wavelengths. Carbon dioxide lasers have the ability to maintain a continuous and high level of power and are typically used for purposes like cutting, welding, etching, and marking applications.

Diode lasers are tunable and allow for adjustments so that they can emit any one of several different wavelengths. The other type of laser is fiber laser that uses optical fibers that are doped with low levels of rare-earth halides used as lasing medium for amplifying light.

Each of the above laser types has its individual laser-making systems, which can be varied according to their use. The strength of different types of lasers produced by different laser systems makes them versatile enough to be used for cutting even sensitive and delicate substances like thin cotton, and also to be used for cutting, scribing, marking, joining, and surface treating a variety of hard materials and metals.

A lot of these laser-cutting systems are high precision equipments. These are attached to computers that control the exact amount and strength of the laser beam. These are excellent for delicate or precision cutting as per exact requirements.

Thus, the choice of a particular laser system totally depends on the type of material that the laser is to cut as well as the purpose of the cut.

Laser Cutting Machines

The word laser is used as a common name, but it is actually an acronym that stands for Light Amplification by Stimulated Emission of Radiation. The highly concentrated beam of light it produces can quickly apply energy even to a minute area. It can be easily controlled by mirrors and lenses and essentially as light. It can travel at the highest speed possible, can travel in a straight line in an empty space and can transmit information.

With these properties of laser light, laser has found numerous uses; among them is in cutting. A laser cutter works by focusing the huge amount of energy it produces on a small area (even microscopic). The constant beam of light that hits the area causes it to melt or evaporate. A cut is generated by moving the object being cut or by moving the laser beam across the surface.

As a tool in cutting, a laser cutting machine has several applications. Some of its well-known applications are in medicine as a surgical tool, in craft-making and lithography as an etching tool, in garment industry as fabric cutter and in metal fabrication as welding and cutting tool.

Laser cutting of metals is laser?s most common and most beneficial industrial application. By means of a laser cutting machine, metals with complex profiles and contours can be easily and seamlessly cut. Its high quality cutting capability and fast cutting speeds eliminate further processing of metals, reduces production cost and improve productivity of certain companies using the technology.

The advancements in laser cutting machines, which includes enhancement of the beam quality, laser power, ease of use and operation and material, made it possible for a laser cutting machine to cut metals with multi-dimensions and tubular profiles. Highly advanced laser cutting machines with this capability are quite helpful in the automotive industry.

Among the laser cutting machines used in cutting metals are flying-optic lasers, hybrid lasers, punch-laser machines, pivot-beam lasers and pulsed lasers.

Flying-optic laser cutting machines have high cutting speeds yet they are less expensive because of their fixed X and Y axis table. They are able to move over the material being cut in two dimensions. A more efficient and powerful pivot-beam laser on the other has X axis-travel capability.

Punch-laser machines are high power lasers that can cut metals with up to 3,500 watts. They perform several tasks including punching, marking, contouring and bending. They are mostly used to cut outer part and intricate inner contours. Pulsed laser machines on the other hand produce high power output for short period. They are ideal for piercing because of their ability to produce high power output in a short time.

Astronomy Laser Pointers - Cutting Edge Lasers Improve Astronomy Pointers Science

The scientific community which has benefited the greatest from improvements in laser light and laser pointer technology is the field of astronomy. It seems there are no more perfect applications for high power laser pointers than to be used for research in the physics based world of astronomy. But how practical is the use of astronomy laser pointers? Does it provide legitimate scientific value, or is it merely a tool used to make research "cool" or "hip"? There has been much debate regarding laser use for astronomy based research in observatories throughout the globe.

If you are a laser hobbyist, or an astronomy enthusiast, you may be familiar with practical laser pointer functions that are ideal for night time studies. But what is it that a person should be looking for to determine if a specific laser pointer will be ideal for their astronomy needs? There are a few things to ponder before applying a laser to astronomy research, points which anyone considering using a handheld astronomy laser must contemplate.

First, where are you going to be using the lasers? If you are in an area that is relatively high in population, you may have to combat light pollution in order to see the night sky's constellations. If this is the case, you will need to obtain a high power pointer so that you can actually see the laser beam clearly despite the adverse conditions. We can take this a step further, if you know that you will require a bit higher power for your laser, then you may also want to consider utilizing a 532nm green laser pointer. Green astronomy lasers are the most commonly used laser pointer because of how bright the green laser beam appears to observers. The green beam is the brightest light frequency in the visible light spectrum, which means there is no laser beam that can appear brighter. Accordingly, green lasers are the most popular color wavelength for this type of use.

Green lasers have a long history of use in space frontier organizations such as NASA, and continue to gain popularity amongst astronomers across the planet. The problem currently is that many scientific professionals are not properly trained in laser usage for astronomy applications, and this is cause for potential disaster. Now, if someone is using a 5mw green astronomy laser, there is very little danger to worry about. The beams output power is relatively low and that keeps everyone around safe.

If a high power unit is to be used, there is a bit more room for concern and precaution. The higher the output power of the laser beam, the brighter and stronger the beam will appear. This may be ideal for night based astronomy research, but if the beam becomes dispersed or used improperly it can spell disaster for the astronomy enthusiast or simply people who are present. There has been horror stories of astronomy laser pointers gone wrong which lead to large research grants being canceled.

So if pointers are your forte, be sure that you know what you are doing before you engage the powerful lasers. The use of a straight line of green laser light is unmatched by all other astronomers tools, and when a laser is attached to a telescope, astronomy becomes that much more exciting as well as educational. Some of the worlds largest and powerful observatories attach simple astronomy laser pointers to their scope's casing, allowing for consistent and solid beam output. Lasers are opening the door and people's eyes to the beauty of the universe and our milky way galaxy, be sure to shine with care and enjoy.

James has been involved with astronomy lasers since the scientific community first incorporated the tools into global research several years ago. His preferred laser retailer provides professional astronomy laser pointers and astronomy lasers
