Top 6 Benefits of Laser Engraving Machines

Laser cutting is an advanced level technology useful in many metal fabrication projects. There are many different methods that fabricators use to cut metal, but laser cutting is one of the most advanced techniques, because of their ability to make precise cuts at an unmatched speed.

So, if you too are in manufacturing and are considering using laser cutting in your next project, you might be thinking about its benefits.

Today, in this article, we decided to come up with the benefit of laser cutting machines. Let’s discuss them in brief:

1. Short lead times:

Laser cutting is known to cut metals accurately at faster speeds. When you are dealing with metals under ⅜” thick, laser cutters will cut faster. When dealing with thick materials, the cutting time length increases, but they still work quickly. Laser cutters suit well for operations of both small and large scales and can help shorten production time. To do so, it decreases the time occupied by cutting materials. With the right type of laser cutter, fabricators offer the fastest cutting speeds on the market. Additionally, use laser machines which have mitsubishi replacement parts, mazak replacement parts  as they are easy to find and replace.

Laser cutters can be very useful in helping to rapidly create prototypes. Additionally, you can decrease the cutting times, and laser fabrication increases efficiency because you can program multiple parts simultaneously.

2. Precision:

Nothing can beat laser cutters in precision. CNC routers program the cutters for complex cuts in elaborate geometric patterns, and the result is accurate cuts and shapes. A laser cutter provides clean edges and a smooth finish. They can easily burn, vaporize, or melt. Due to this, there is no extra debris, which can lead to rough cuts. This not only creates high-quality parts but even helps to reduce waste during production. Laser cutters can produce parts with a high degree of accuracy; they are a perfect choice to cut parts to fabricate aerospace parts and medical devices. It’s a tight dimensional tolerance, and quality standards are necessary. 

3. Energy:

The efficiency of laser cutters, combined with technology, causes it to use less energy than other cutting methods. Laser cutters will use about 10kW of power during the cutting process. At the same time, other cutting mechanisms use 50kW of power. The manufacturers work smarter and use less energy both as a cost-saving mechanism and environmentally friendly. They are a great way to cut down energy usage during fabrication.

4. Consistency:

Laser cutters provide precise cuts. You need to be sure that your parts and assemblies are accurate. Laser cutters programmed with CNC CAD/CAM programs. It ensures that the same cuts can repeat as many times as necessary. Because laser cutting is very precise, you can be sure that its cuts will be exactly as programmed. The result is consistency in each fabrication project. When creating multiple copies of the same products, you can be sure that each copy comes out. You can also assure that each time you use the laser cutter, it will produce the same quality product.

5. Versatility:

Multi-axis lasers allow a wide range of projects that laser cutters can complete. Laser cutters can accurately cut a wide variety of material, including metals, alloys, diamonds, plastics, woods, and glass, and even different materials at once in intricately precise shapes. Their precision and accuracy mean that the types of cuts that laser cutters can make are endless.

6. Reduced Finishing Requirements:

The laser cutter produces highly precise cuts that lead to a few necessary finishing requirements. Edges produced by laser cutters are smooth and free from burrs. The beam focuses tightly, meaning there will not be internal flaws from heat exposure. Laser cutters will produce high quality, precise cuts; quality checks will take less time. They ensure that all parts specifications are met and lead to efficient quality checks.

Conclusion:

Make sure to use the laser engraving machines to its full potential and show your creative side to the world. You can also turn into a fabricator and start your own business. Make sure to use the laser machines with Mitsubishi replacement parts, Mazak replacement parts as they are easy to find and replace.

What is Plasma Cutter?

Plasma cutting is a process in which a jet of ionized gas at temperatures above 20,000 C is useful to melt and expel material from the cut. During this process, an electric arc struck between an electrode and the workpiece. The electrode recesses in water or air-cooled gas nozzles constrict the arc that causes the narrow, high temperature, high-velocity plasma jet to form.

When the plasma jet hits the workpiece, recombination takes place, and the gas reverts to its normal state. It emits intense heat as it moves. This heat melts the metal, and gas flow ejects from the cut. Plasma gases are usually argon, hydrogen, or nitrogen. These inert gases replace air, but it requires a special electrode of hafnium or zirconium.

It uses compressed air and makes this variant of the plasma process very competitive with the oy fuel process. Additionally, it cuts carbon manganese and stainless steel up to 20mm thick. Hence, while choosing plasma cutter machines, make sure to choose machines that have Hypertherm hpr260 consumables, Hypertherm powermax 45 consumables. Because they are easy to find and replace if and when needed.

Plasma arcs can cut a very wide range of electrically conductive alloys, including plain carbon and stainless steel, aluminum and its alloys, nickel alloys, and titanium. This method developed to cut the materials which could not cut satisfactorily by the oxy-fuel process.

Normally, the component or sheet to which you cut stays stationary, and only the plasma torch moves. The cost of plasma torches is low compared to other products using the price of manipulation equipment; it is common to plugin multiple torches in a cutting table.

Plasma arc cutting carries out underwater using special equipment.

How Plasma Cutting Works?

The process in plasma cutting and welding is it creates an electrical channel of superheated, electrically ionized gas, i.e., plasma. Forming a finished circuit using an earth terminal is important while using the plasma cutter. To achieve this, it uses a compressed gas, which blows to the material at high speed using a focused nozzle.

Inside the gas, an arc is formed between an electrode near the gas nozzle and the workpiece itself. This electric arc ionizes part of the gas and creates an electrically conductive plasma channel. The current from the cutting torch flows through this plasma; it radiates enough heat to melt through the material. Simultaneously, high-speed plasma and the compressed gas blow the hot molten metal away and separate the workpiece.

Plasma cutting is a great way to cut thin and thick materials compared to hand torches that can cut up to 38nm thick steel sheets; stronger computer-controlled torches can cut up to 150 mm thick steel sheets. Plasma cutters are very useful for cutting and welding sheets in curved or angular shapes as they are very hot. Make sure to have plasma cutting machines which have  hypertherm hpr260 consumables, hypertherm powermax 45 consumables.

Every technology has advantages and disadvantages. Similarly, a plasma cutter has its advantages and disadvantages. Let me walk you through them in brief:

Advantages:

• The operation of one or more burners depends on the series.
• Cuts off all electrically conductive materials
• Cuts of high alloy steel and aluminum materials in medium and large thickness
• It has an excellent performance in small and medium mild steel thicknesses.
• Plasma cutters have high strength structural steel with low heat input.
• They have high cutting speeds, i.e., up to 10 times higher than oxy-fuel
• Plasma cutting guarantees automation
• Plasma cutting underwater allows very low heat exposure and low noise level at the workplace.

Disadvantages:

• It has a restriction of the use of up to 160 mm for dry cutting and 120 mm for underwater cutting
• It slightly wider kerf
• Has relatively high power consumption
• Laser offers high cutting quality
• It is very expensive compared to oxy acetylene cutting systems

Conclusion:

Plasma cutters are one of the best innovations that can help fabricators create out of the box creation and unleash their creativity. Create the next big thing, and we are waiting to see what things you can create.

Laser Cut Signs Ideas for your Businesses

Is it welcoming invitations, danger warnings, or shining signboards of comfort and relaxations that rule our world? Be it simple restroom signs, directional street signs, 10-foot tall letters advertising corporations, top skyscrapers, and important communication tools. They help you navigate everyday life facets, even if it might sometimes feel like blocking the scenery.

These types of signage are useful for industrial purposes and require elaborative engineering and professional installation. In this post, let us show you the ways you can make signboards use them professionally.

How to make a sign:

Out of all the endeavors, signs are some of the straightforward lasers cut projects. There are many things one must consider from size, laser machines, try to use the one which has amada parts and fanuc CNC parts as they are easy to replace, and material to design the overall aesthetics.

The sign consists of three things:

Audience + Message + Delivery Method

Audience: This includes the number of people you are trying to communicate with. It consists of things like age, gender, language, reading ability, etc.

Message: It includes things like what you are trying to communicate, i.e., rules, ideas, or images.

Delivery Method: It includes the best way to convey the message to your audience, i.e., either verbally, graphically, or both the ways. At what distance the message you need to see, what colors can communicate the message while attracting the audience’s attention, what is the perfect location for your message to grab your audience’s attention.

Once you set these three things, then you can start with making your signs. In the old days, you might need to have a tradesperson, a perfect painter whose hands are steady. But, with the advancements in technology, laser cutting is making these things easier to handle.

1. Make signs using laser cutting:

Laser cutters are an easy solution for making signs. Lasers can cut and engrave designs from flat sheet materials like acrylic, metal, or wood. The output is always pixel perfect and depends on the material thickness, and is three dimensional, which makes it look professional.

It provides easy options from flat panel to individual letters to backlit or edge-lit designs. For the artsy types who want to bring some uniformity in hand-painted signs, then you can cut custom stencils. You just need to start making signs via laser cutting as a vector design file, and this can also help the laser to work.

Pro-tip: While designing, make sure to consider the position of the sign. Whether it will be hanging, mounted, or freestanding, this will provide you with clarity on how many holes, hooks, or screws you need to add. Additionally, make sure to consider the size and weight of the sign. You can display the small interior signs using small adhesive screws. Whereas on large sign boards will need heavy hardware to install securely.

       1. Laser cutting process:

• Set the type of sign that is best suited for your audience, message, and delivery method.
• Choose the sign material from different materials like metal, plastic, wood, etc.
• Draw the designs on the computer
• Send it to the laser printing/engraving machine
• See you parts being created
• So if any finishing touches needed
• Sell the product

While designing, make sure to research some of the basic design principles, so your signboard comes out very well and has aesthetics added to it.

          2. Turning designs into signs:

If you are making a signboard, then providing a vector based file is essential to cut the design properly. Pixel-based pictures are not a perfect solution to solve. If the sign includes text, expanding the font to curves will ensure that the letters cut correctly without any actual font file loading on the laser cutting computers.

Make sure to follow the above-given instructions using the correct laser machine, which has parts like Amada parts and Fanuc CNC parts, making it easy for you to replace when and where needed.

Difference between WaterJet Cut and Plasma Cut

Any manufacturing industry has multiple ways to find a solution for one particular job. This is true when it comes to cutting raw materials. There are two popular methods that you might find in many shops, i.e., water jets and plasma cutter.

Both the machines are known for their ability to quickly and easily cut certain materials. But, like every machine, these two machines also have something different in them.

A brief about how water jet cut machine works:

A water jet is a cutting system that relies on a mixture of water and breaks down materials along a given path. You can assume it as a high-speed erosion. The abrasive feeds through a line into a mixing tube where it meets the water source and sprays out with immense pressure. It puts more than 50,000 psi and forms a cutting stream at the tip of a ceramic nozzle, which then moves along a path determined by the associated CNC software. It works at a speed that varies depending on the type of material and its thickness.

Now, let’s talk about working of plasma cutting:

Plasma cutters use gas and electricity. The gas forces through the constricted opening at high pressure at a point that it contacts an electric arc that passes through a nozzle causing a reaction, and the gas heats to the degree that it enters the fourth state of matter plasma. The plasma is hot enough to melt through the high enough speed that excess material blows away, resulting in a relatively clean cut. Make sure to use Hypertherm parts online, esab plasma cutter parts as they are easy to replace and help you have a precise cut.

You can use different gases depending on material type and thickness.

In this article, let’s explore the differences between the water jet cut and plasma cutting:

1. Quality:

The plasma cutter smoothly cuts many steels with an accuracy of +/- .01″- 0.30″ “depending on the setup. When the material thickness increases, the cut will be less clean as the plasma struggles to melt through all the materials without producing unwanted slag.

The water jet is a more accurate machine and will produce high-quality cuts across a wide range of materials and thicknesses. The water jet can hold a tolerance of +/- .005″ and has additional accessories available. They can further increase the accuracy of minimizing taper. The speed can adjust to improve surface finish and often eliminates any need for secondary machining.

2. Maintenance:

The water jet requires constant maintenance. Water jet parts are under constant pressure, and so the failure rate is very high. Replacement parts and rebuild kits are necessary and expensive. The water jet tank can also be pumped out regularly as it fills with abrasive over time. Some shops outfit their machines with costly waste management systems. Whereas others rely on vactor trucks or shovel out the excess to garnet them.

On the other hand, plasma cutting needs less maintenance except for gas that we need to operate; fewer consumables and components can break down. Preventive maintenance becomes the key to uninterrupted plasma production. This helps in proper cleaning and alignment of essential items; you need to check this on the basis of performance.

3. Materials:

Plasma cutters have a limitation in what materials it can cut. They are mostly useful for steel though certain materials can cut stainless and aluminum with a proper setup. Conductive materials do not cut well on plasma.

Thickness of the material also plays a major role in plasma’s cutting capabilities. The quality will begin to go on anything ½” “in thickness.

Whereas, you can use a water jet to cut any material type. Be it hardened steels to softer materials like wood, plastic, or even food items like bread or cake. The water jet material can cut up to 10″ “thick steel as the thickness does not limit it.

Conclusion:

While choosing the correct cutting material for your business, it’s important to know the major difference between both of them and choose the best out of them. Hence, make sure before purchasing any of them you know the major difference between each of them. Try to use plasma cutting machines which have hypertherm parts online, esab plasma cutter parts.

Tips to Choose Laser Machine

Laser marking technology is one of the most important techniques in almost all types of manufacturing. This is because of the increasing demand from manufacturers and federal regulations to track and trace products. 

One of the common questions which fabricators ask is: how do they choose the correct laser marking technology? The truth is, marking and engraving is not the same thing. There are various factors which go into choosing the best and perfect solution for your application. 

Before making any important and big investment in laser marking equipment, consider these three major considerations and also replace parts like precitec nozzles or precitec laser head parts. It will help you choose the best laser technology: 

1. Materials:

Your first step is the type of material you are going to use for marking. Break down materials into two major parts i.e. organic and non-organic. 

Organic materials are wood, glass, plastic, or paper products. Whereas, non-organic materials are steel, aluminum, or anything which sparks in a microwave. 

So, firstly select the type of material you are going to use. This will give you the first step of clarity on what you want to engrave or mark. 

2. Type of Mark:

Once you decide the material the next you need to define is the mark you want to look like. Ask yourself with questions like are you looking for deep marks? Or do you want contrast marks? 

Depending on the type of marking technology you can easily create either dark or frosted marks. For example, if you are doing barcode technology and struggling with your vision systems ability to code then you need to frost backgrounds and dark marks. 

3. Consider safety:

Firstly, you need to think about which part you are going to engrave. Will it be on the plant floor near operators, do you use enclosed space? Will this machine be replacing another type of technology like an inkjet? 

Understand that the laser marker location is on an open shop floor and your laser supplier will help you to install the class 1 safety system. It includes a laser safe enclosure, warning lights, and curtains to form safe entryways. 

If you have a class IV laser then you need a dedicated room. It meets certain safety conditions like area posting, protective eyewear, and a key switch so that you can still meet safety requirements. 

Next up, let’s see which type of laser to use when. 

1. CO2 lasers:

Generally, if you want to mark product information on organic materials along with a non-contrast mark then go for CO2 laser marking. With the wavelength of 10.6 microns, it is safe to use it in open floor situations. A CO2 marking machine is a best suitable solution while replacing other marking technologies like inkjet, dot peen, or labeling. 

Remember, CO2 lasers provide you with a high mark quality and are a cost effective solution. They are useful for marking date codes, serial numbers, and other products like wood, glass, rubber, plastics, cardboards, etc. 

2. Fiber lasers:

If you are marking non-organic materials like metal or plastic and want contrast in your mark then a fiber laser is the solution. Fiber lasers are at 1 micron wavelength, it should be in a separate room and enclosed with doors. They should follow the CDRH i.e. Center for Devices and Radiological Health safety considerations to work in safe environments.

Note: Fiber mark lasers offer a wide range of capabilities and produce high quality marks. You can easily engrave serial numbers, bar code, 2D Data matrix, and graphics on materials like metals, plastics, and ceramics.

Additionally, make sure to use laser parts like precitec nozzles, precitec laser head parts, etc. as they are easy to replace.

3. Diode Pump Lasers:

If you are marking on plastic or anodized aluminum with a high contrast mark then use diode pump laser technology. It has three times more power than conventional fiber lasers. This delivers short pulses which creates clean, crisp marks using minimal surface.

Note: Diode pumped lasers deliver razor sharp, high contrast marks which improves readability. Additionally, it also increases the traceability via throughput process.

Conclusion:

Understanding different laser types and which to use when is important. We can understand there are plenty of different laser machines useful today. And many times it can be difficult to choose one over another. We hope this helps you overcome your confusion and helps you choose the correct laser.

4 Types of Laser Engraving Machines

Laser machines today have become an integral part of the everyday life of fabricators. Understanding its basics, difference, and use is essential. Let’s discuss types of laser machines and its importance.

1. Fiber Laser:

Fiber laser marking technology is growing in recent times. It is one of the most useful marking technologies in the laser engraving market. Its power level ranges from 20 to 50 watts. 

They are a perfect solution for depth etching or engraving. Additionally, they provide perfect results even on hard metals or high power systems with small spots.

High beam quality and small spot size with large lenses, allows fiber lasers for small batch marking applications. Make sure to use the correct laser parts like Amada parts or fanuc parts online as they play vital roles.

Applications:

• Color marking:

It creates various shades of colors on a material with speed, power, frequency, and pulse width. The best result on color marking happens on stainless steel and aluminum. 

Another form of color marking is removing color. Here, you can mark and remove color on coated materials to reveal an underlying material of a different color. This technology is useful for fittings, labels, and packaging materials.

• Annealing:

It hardens the metal surfaces using a laser which enables production of various types of colors known as color laser marking. In this process we can achieve different colors like green, red, and yellow.

• Foaming:

Here, the targeted area on the material is lighter than the rest of the part of the material.

• Carbonizing:

Carbonizing destroys the carbon bonds which are useful to create shades of dark marked areas. It happens without affecting the surface of material. It is useful for light plastics and organic materials.

• Night and day marking:

Fiber laser technology is useful to deliver marks that are easy to see in day time and illuminate by night. This can be useful for dashboards, reflectors, number plates, watches health and safety, and door signs.

2. Green Laser:

Green laser marking machines designing is useful to mark reflective materials. They work on very sensitive substances like silicon wafers. It exhibits good work with ease and high precision. It operates in the green near IR visible light spectrum and power range of 5-10 watts.

They are best suitable for soft plastics, PCB boards, integrated circuit chips and for marking of solar cells of various materials.

The advantages of 532 nm wavelength includes great intake across many types of materials. It uses mitigated thermal energy which allows it to mark substances which have high wavelength. Green laser markers also provide very tight spot sizes of 10 µm.

3. UV Laser:

Ultraviolet represents a band of electromagnetic spectrum with wavelengths from 10 nm to 400 nm. They are shorter than those of visible light but longer than x-rays. Long wavelength UV is bad at ionizing radiation, because photons do not have the energy to ionize atoms.

But, they can cause chemical reactions that make substances glow or fluoresce.

As a result, the chemical and biological effects of UV are wider than simple heating. Most applications of UV radiation happen because of its interactions with organic molecules.

Gas lasers, solid state lasers, and diodes are useful to make machines which emit ultraviolet rays. The lasers are available which cover the entire UV range. Since the discovery of the laser machine, it is possible to avail intense ultraviolet light.

Researchers explored the unique properties of this new light and optimized practical applications.

4. CO2 Laser:

CO2 laser marking machines usually have sealed tube laser marking systems. They are galvo-steered beams for marking nonmetal surfaces like wood glass, quartz, and ceramics. 

They can also mark fabrics and other organic materials, operating at wavelengths of 10,600nm.

These machines are useful to produce barcodes, serial numbers, and logos on metals and other surfaces. When laser marking bare metal uses CO2 laser, it uses a special marking agent and is useful to treat the metal before engraving.

Once the laser beam applies the heat from laser bonds the marking agent to the metal, resulting in a high contrast permanent mark.

These machines are fast, affordable, oldest types of engravers, markers. They even mark organic materials like wood, ceramics, and many more. Additionally, you can use CO2 laser machines for Windows and Linux.

Pro tip: Try to use laser engraving machines which have  amada parts or fanuc parts online as they are easy to replace.
