Should I pay for laser cutting services or invest in my own machine?

From OEMs to shipbuilders, companies in a wide variety of industries require cutting of metal plates or sheet metal as part of their manufacturing process. Very simple components are sometimes produced by guillotine but the majority of parts require more sophisticated machinery and expertise and many companies turn to specialized external laser cutting services.

But is an external laser cutting service truly the right choice for your specific metal fabrication needs? Or would it, in fact, be smarter to acquire a CNC metal cutting machine yourself?

By using an external laser cutting service you avoid the high capital investment needed for purchasing a machine, whilst relying on sub-contractors metal cutting expertise. However, because of the increased flexibility & speed, lower cost per part and keeping control in house, purchasing a metal cutting machine will often pay back within 1–2 years.

If you are cutting metal materials and care about cutting speed and accuracy, it must be a laser cutting machine.

BEST METALS FOR LASER CUTTING PROJECTS-PRECISION LASER CUTTING

Laser cutting is a marvel of modern technology in the industrial and manufacturing market. It is an extremely versatile way of creating parts in a large variety of materials. Laser cutting is so versatile that it can be used to cut woods, plastics, acrylics, and metals for both structural and decorative purposes. When it comes to parts that last and resist wear and tear, metal has always been the go-to option, but there might be some options for lightweight or technical parts.

What metals can be used with laser cutters? Technology continues to advance to make this question moot. Currently, almost all metals can be laser cut, but there may be some requirements depending on the material that might be chosen. The different types of materials can be broken into 3 categories:

Ferrous, Nonferrous, Synthetic

Each of these has different applications, requirements, and laser needs.

Ferrous

Ferrous metals are metals which contain iron. Other non-reflective metals are also grouped with ferrous metals. Most commonly, steel, stainless steel, and iron itself are considered for manufacturing in this category. These metals are extremely strong and versatile and are used for their strength. Materials in this category are used for structural and high-stress applications. Parts made with these metals are able to hold up under high pressure and heat with less chance of distortion.

When it comes to cutting, these materials are easily cut by a number of different types of lasers. This versatility also makes it nice for cutting. Its resiliency and non-reflective properties when it comes to laser cutting also allows for modern lasers to be able to cut pieces that are thicker than some other options. Once cut, these parts should last a long time, but they are not always the best for more delicate applications or applications where electro-conductivity is sought after. The costs of ferrous materials can very depending on the type of material and the thickness, but is usually in the middle of non-ferrous options.

Non-ferrous

Non-ferrous metals include aluminum, magnesium, copper, silver, gold, titanium, zinc, etc. With lower electrical impedance and heat resistance, these metals are used in more delicate applications where ferrous metals might not be the best option. Some materials will not survive the same conditions as the ferrous metals. For example, aluminum is a great option for lightweight gears or technical parts that won’t experience massive amounts of stress, but still need to be able to function properly for a reasonable amount of time. Copper or gold might be a better option to consider if a piece needs to be able to conduct electrical charge.

When it comes to laser cutting, these metals also are much trickier to cut and require specific types of laser in order to be cut effectively. Without the proper laser and settings, damage can occur to the piece or the machinery creating costly mistakes. Usually these materials are not able to use a standard CO2 laser and require a fiber laser to cut. Gold, silver, and copper are so unaffected by a CO2 laser that it requires a fiber laser. Even with a fiber laser, the thickness of the material that can be cut is much less than ferrous metals. Greater thickness requires longer exposure to cut the material and these metals are far less resistant to the heat and other environmental factors created by the process. The price of possible materials in this category vary greatly with aluminum and zinc often being examples of less costly options and gold and platinum being examples of some of the most costly options.

Synthetic

While obviously not metals, most synthetic materials (and even woods) are generally used for aesthetic embellishments and decorative pieces. That being said, polyoxymethylene, or POM, is an engineering thermoplastic that has some applications in parts production. Sometimes called Acetal or Delrin, this is a resilient plastic that can be used for technical parts and lightweight gears. It is is great at keeping its shape without warping and breaking like is seen from other synthetics such as acrylic.

POM is easily cut by a number of different lasers. It is also waterproof, weatherproof, and resistant to most acids, bases, and other solvents.

6 POPULAR USES FOR LASER CUT PARTS

Do you have a laser cutter for your manufacturing facility, or are you thinking about investing in one?

Laser cutting is a versatile process that has become a staple in many industries over the past few years. Advances in technology have allowed laser cutting to be used for a variety of different materials.

Laser cutting can be used to cut a precise line through a thin plate of steel, engrave, or mark many different materials with varying degrees of thickness. The idea of cutting gears and other flat parts is probably the most apparent use for laser cutting, but it has many other interesting uses as well.

Learn 6 of the most popular uses for laser cut parts below.

Popular Uses for Laser Cut Parts: 6 Industry Applications

Laser cutting is most commonly used in the automotive, die, mold, tool, jewelry, and medical industries. It can be used to create parts for medical devices, computers and electronics, and much more. Materials that are difficult or impossible to cut using other methods make excellent candidates for laser cutting.

“The use of laser-cutting across all industries is expected to grow by 9% before 2023.”

It’s no surprise that laser cutting has become so popular. It offers several advantages over other methods. High accuracy, precision cuts, low lead times, less waste, lower power consumption, cutting versatility, the ability to handle complex jobs, and the lack of damage to thick materials make laser-cutting far superior. You’ll be able to cut costs and achieve higher quality results with laser cutting.

1. Automotive Industry

With laser cutting’s ability to accurately reproduce parts relatively quickly, it has found a home in the automotive industry. The automotive industry has a great need for exact replicas of a part of different shapes and sizes. Laser cutting it used to cut metals and plastics to form body pieces of the vehicle, electronic components, as well as interior covers and buttons.

Additionally, laser cutters can be used to engrave buttons on the interior of the vehicle to have the light come through or even to record the serial number and part number onto manufactured pieces. The dies that are used for cutting different pieces can also be laser cut.

Laser cutting lends itself to being able to cut hydro-formed parts. These are usually strong tubes that are used to lend support within the structure of the vehicles. Commonly, these pieces are used to create the engine frame or the instrument panels.

2. Die, Mold, and Tool Industries

As mentioned above, laser cutting can also be used for making dies to cut replica pieces. With the laser’s ability to cut different depths into the metal, an extremely accurate die can be made for stamping pieces that will last through the repetitive process of die-cutting.

Laser cutting can make replicating the die a quick and accurate process as well. Laser cutting can be used to make injection molds with the same accuracy that it does with dies. This simplifies the process of mold making and makes reproducing the mold precisely a much less time consuming and costly endeavor.

Within the tool manufacturing industry, laser cutters can be used not only for marking and engraving as done in the automotive industry, but also for the manufacturing of simple hand tools. The speed of laser cutters might even make it better than die-cutting on sturdy metals. With its versatility of material usage, you can even use the laser to engrave company logo and tool information onto the rubberized handles of most tools.

 3. Jewelry Industry

The precision of laser cutting lends itself easily to the jewelry making process. For example, visualize a watch with its many small gears. Lasers cut with such incredible accuracy that gears can be made with less waste and less production time. In addition, the laser’s engraving capabilities can mark the parts as part of the manufacturing process.

Since the laser can cut precise shapes and thicknesses, laser cutting can be used to make jewelry as well. Creating a ring or bracelet of an exact width, depth, and diameter is easily done by the laser. The laser can also be used to engrave designs and inscriptions onto the interior or exterior surface of the piece.

4. Medical Device Manufacturing

Laser surgery and the creation of medical devices are the most significant benefits of laser cutting in the medical industry. Surgeons can make more precise cuts, and patients heal from laser surgery much faster. Laser-cut parts are used to create medical devices that improve the quality of life for patients. For example, stents, valve framers, vascular clips, bone reamers, flexible shafts, and hones are all manufactured with laser cut parts.

5. Ceramic Manufacturing

Ceramics have several properties that allow them to be used for a wide range of applications for engineers. Low electrical and thermal conductivity makes them excellent insulators, they don’t react with other chemicals, they have high melting points, and they are incredibly durable. Lasers are frequently used to cut ceramics because they reduce processing time without compromising edge quality. Airplane jet engines, electric motors, loudspeakers, headphones, power plant generators, electric cooktops, and even incandescent lamps all have ceramic parts.

6. Silicon Manufacturing

Silicon is another material with a wide range of applications that can benefit from laser cutting. Precision cutting allows engineers to produce smaller silicone parts than is possible using other cutting methods. Silicon is tolerant of high temperatures, age-resistant, and is easily manipulated. Typical applications for silicon are found in computers, electronics, textiles, household products, automobiles, and architecture.

An Important Player of Localizing Laser Cutting Technology for 1000kg+ Ultra-heavy Tubes

In recent years, high-power laser cutting is in full swing in China, however, fewer manufacturers have stepped into oversized, ultra-heavy or super-long tubes cutting. In this field, HSG Laser is one of these few enterprises that make efforts on relevant R&D.

Before the year of 2019, the market of heavy-duty tube laser cutting machines were mainly dominated by Japanese MAZAK. But, its FABRI GEAR 400 II, designed for cutting Φ406mm, 890kg round tubes, was sold at the price of RMB 8 million. Restricted by heavy tube clamping technology, the domestic tube laser cutting machines usually carried 200kg single tube at most at that time.

To change such situation, HSG Laser has devoted itself to core technologies for several years and developed “double pneumatic+ double hydraulic” four-chuck clamping technology, special bus control system and automatic loading & unloading system. TL500, a four-chuck ultra-heavy tube laser cutting machine launched in Nov. 2019, can cut Φ426mm, 1500kg, 12000mm tubes easily. Since that, HSG has emerged as the first manufacturer that can handle with 1000kg+ tubes in China.

To address rising needs for cutting heavy channel & angle steels and other profiles raised by steelwork construction, elevator manufacturing and other industries, HSG Laser launched TX Plus in Apr. 2020. Its max. capacity lies in cutting Φ325mm, 600kg tubes and profiles.

HSG Laser always regards technical R&D and front-line demands of users as its driving force, so as to help engineering machine manufacturing, modern agriculture, mechanical equipment, elevator manufacturing, wood-working machine manufacturing, rail traffic and other relevant industries to transform metal processing methods and upgrade to high-precision production.

Bus Control System for Tube Cutting Machines －HSG-X9000

For tube laser cutting machines, control system, chucks and cutting head play a crucial role. Until now, HSG Laser has been capable enough of independent research and development in these three aspects. CNC system, as control center, is as important as people’s brain because it usually gives instructions to chucks, cutting head, support frame and other components. This considerable component is directly related to operating performance, stability and cutting effects of the whole machine. At present, marketable CNC systems prefer to one-to-one hardware data transmission, however, which are likely to be interrupted by external factors during signal transmission because of numerous but tanglesome lines. Except for that, troubleshooting that may happen is time-consuming and may give rise to a substantial decrease in cutting precision. In view of these issues, HSG has spent three years to develop X9000 bus control system based on HSG-X9000 tube cutting system and applied it to R5, TM65 II and other favorable models as a standard configuration. X9000 bus control system has following features: 1.Make rapid but stable data transmission possible only via a network cable, so as to minimize troubleshooting and maintenance duration by disappearing messy wiring 2.Create a significant increase in signal interference immunity and electrical stability, then, take accurate control of laser energy and cutting speed 3.Minimize the command response time and speed up data transmission 4.Easy to offer multi-axis control by its strong extensibility In the final analysis, X9000 bus system will bring you: 1.Higher cutting and no-load speed 2.More accurate control of cutting position and laser energy 3.More stable cutting process ...... Applicable models: TM65 II, R3/R3 Plus、R5/R5 Pro and new generation of TX series.

What is the application of 10kW+ laser cutting machines in the shipbuilding industry?

Since first launch in 2013, 10kW+ fiber lasers have become homemade and mass-produced in China, which also heat up the acceptability of high-power and ultra-high-power fiber laser cutting machines in Chinese manufacturing industry. As thus, 10kW+ fiber laser cutters are popular in laser cutting industry and become increasingly important in domestic spaceflight, shipbuilding, automobile and energy equipment manufacturing industries.

During shipbuilding, both cutting and welding are highly involved and considered as the most time-consuming and costly process. As the 10kW+ laser cutting machines and fiber laser welders have attracted more and more attention in recent years, the rapid and high-precision shipbuilding will dominate the development trend of shipbuilding industry.

In general, shipbuilding industry makes high demands on the ship hull segmentation and rotation, that is, frame rotating gap must be controlled within 1mm. When ribbed plate was laid off in the form of plasma by shipbuilding enterprises in the past, the cutting allowance must be reserved to ensure enough assembly gap, besides, manual cutting was also needed during on-site assembly, but, except for greatly different cutting quality, residual oxides may happen in cutting gap. As a result, assembly workload and duration are increased.

For customers in the shipbuilding industry, it is 10kW+ laser cutting machine that is good at solving this problem. With high cutting precision, the deviation of workpiece cut by 10kW+ laser cutting machine is usually within ±0.03mm. It can be said that high-power laser cutting machines can give rise to high-speed cutting and less heat-affected zone, in this way, avoiding workpiece deformation. Taking IPG 12kW fiber lasers as example, 40mm SS and CS, 30mm AL, 15mm brass and 12mm red copper can be cut with high quality. While cutting 12mm CS, the speed can reach up to 1.8-3.5m/min.

Over the years, HSG Laser has concentrated on the R&D and production of 10kW+ fiber laser cutters. Until now, our 10kW+ sheet or sheet & tube metal laser cutting machines account for 25% in our total products. Therein, the maximum power is 30kW, of which extreme cutting thickness reaches 100mm. We can adapt well to the manufacturing and processing of large and heavy-duty ships. We here recommend GH Pro, GF, GV, GT Pro, GHE Pro and GTE Pro to customers working in heavy industries. Besides, our FMW series handheld laser welding machine has been upgraded to the third generation to make laser welding easier for green hands.

What should I do if the laser cutting is incomplete?

Incomplete laser cutting

The solutions include checking whether laser nozzle is matched with sheet thickness, replacing nozzle or sheet metals, detecting whether laser cutting linear speed is too fast, then, decelerating according to sheet metals.

[cora-laserhsg]

What should I do if there are irregular round holes or non-straight lines?

First of all, you need to check whether laser cutting control software is in normal work. Specific practice is to draw a straight line and observe whether laser cutting head moves in a straight line, so as to judge whether software should answer for that. 

Besides, the looseness degree of mechanical structure will also be detected. After that, you need to confirm whether this problem is caused by ultra-high laser energy. To be specific, you must observe the cutting edges. Normally, they are smooth and flat. If so, please lower the laser power or frequency parameters. 

Another uncommon reason lies in the focusing lens distortion in laser cutting head, at this moment, please check whether laser beam is intensive and whether concentricity is qualified.

One laser cutting machine is worth SIX Sets丨See how this company quickly occupied the market!

"We used to have 8 sawing machines, but now only 2 are left, which has also greatly improved the cutting quality."

What kind of equipment makes this company full of praise? Take a look.

This is a leading company in China's commercial space display industry with a history of 17 years. We always insist on customer first and quality first, and have extremely high requirements for product quality and dimensional accuracy.

"We want to replace labor with equipment" As early as 2008, the chairman of the company first proposed the introduction of automated equipment. With this courage, we gradually gained an absolute advantage in the industry and walked in the forefront of the industry.

When the original equipment could not meet the requirements of higher precision and higher ergonomics, we decided to add more equipment in 2018 and chose to purchase the HSG Laser TM65 very small tube laser cutting machine.

"After purchasing the Hongshan TM65, our factory is most intuitively missing 6 sawing machines. Originally, only 2 of the 8 sawing machines were left. That is to say, TM65 replaced 6 machines and 6 workers. And there is no need to cut again after cutting. Grinding treatment has achieved great breakthroughs in quality and processing efficiency." Manager Zhao said with satisfaction.

"We are mainly doing high-end commercial showcases. Customers are first- and second-tier high-end brands. They have strict requirements on product quality, appearance, and precision." Commercial display props are mainly small tubes, and the range of pipe diameters that can be processed by the equipment is realized. The machining accuracy, speed and length of tailings are the focus of the original purchase of equipment.

HSG Laser TM65 fully automated professional laser tube cutting machine, specially developed for cutting very small tubes. The smallest round pipe that can be processed is φ10mm, the processing accuracy is as high as ±0.1mm, and the chuck speed of 170r/min is the fastest compared with the industry pipe machine. The shortest tail length is 125mm, which greatly saves materials and fits the company's processing needs.

Talking about another reason for choosing Hongshan: “Of course, the fast processing speed of Hongshan’s equipment and timely service response speed are also our guarantee. The fast response ensures our normal production. This has strengthened my understanding of HSG Laser. Trust." Manager Zhao said.

Fiber Laser Cutting Vs. CO2 Laser Cutting：Which One is Better?

At present, the fiber laser cutting machine has out-standing advantages compared with the CO2 laser cutting machine and has gradually become popular cutting equipment in the processing market. So, what makes the fiber laser cutting machine beat the CO2 laser cutting and occupy such a big market? Let us give you a detailed analysis below.

 CO2 Laser Vs. Fiber Laser Cutting: The Differences Between Them

Fiber laser cutting machine means that the fiber laser outputs a high-energy and high-density laser beam concentrated on the workpiece's surface. The zone irradiated by the ultra-fine focus spot is instantly melted and vaporized. Compared with CO2 laser cutting, fiber laser cutting machine has advanced advantages and has developed into dominant equipment in high-precision laser processing. A fiber laser cutting machine can be used for plane cutting, pipe cutting, and bevel cutting. The cutting section is neat and smooth to meet the high-precision processing requirements of metal sheets and pipes.

 The Structure of Laser Equipment

In CO2 laser cutting technology, carbon dioxide gas is the medium that generates the laser beam. But fiber lasers are transmitted through diodes and fiber optic cables. The fiber laser system generates a laser beam through multiple diode pumping. It then transmits to the laser cutting head through a flexible fiber optic cable instead of transmitting the beam through a mirror.

In that respect, fiber laser cutting has many advantages. The first is the cutting bed. Unlike gas laser technology, the mirror must be set within a certain distance. There is no range limitation of fiber laser cutting. The fiber laser can even be installed next to the plasma cutting head of the plasma cutting table. There is no such option for CO2 laser cutting technology. Similarly, compared with a gas cutting system of the same power, the system appears more compact because of the bending of the fiber.

The Conversion Efficiency of Electro-Optics

Adopting an all-solid-state digital module and single fiber laser design, the fiber laser cutting system has higher electro-optical conversion efficiency than carbon dioxide laser cutting. For each power supply unit of the carbon dioxide cutting system, the actual general utilization rate is about 8% to 10%. Users can expect higher power efficiency for fiber laser cutting systems for about 25% to 30%.

In this case, the total energy consumption of the fiber cutting system is about 3 to 5 times less than that of the carbon dioxide cutting system, and the energy efficiency is increased by more than 86%.

 The Advantages of Fiber Laser Cutting Over CO2 Laser Cutting

Better Optical Quality 

Compared with the CO2 laser cutting machine, the fiber laser cutting machine has better beam quality, with a smaller focus spot, making the cutting lines finer to achieve better processing.

The Cutting Speed is Faster, and the Processing Efficiency is Higher

Compared with the carbon dioxide laser cutting machine, the fiber laser cutting machine's cutting speed and efficiency are twice that of the same power carbon dioxide laser cutting machine.

 The fiber laser cutting uses a modular design, makes it no optical lens in the resonant cavity. Furthermore, no start-up time is required. Compared with carbon dioxide lasers, fiber lasers have the advantages of adjustment and maintenance-free, and high stability. A good fiber laser has stable performance, and the service life of core components can over 100,000 hours.

From the above comparison, although the cutting ability of CO2 laser cutting is powerful, in terms of energy-saving and cost, optical fiber still occupies a higher advantage. The economic benefits of optical fiber are much higher than that of CO2. In the future development trend, Fiber laser cutting machine will occupy the market of mainstream equipment.

HSG is one of the most famous fiber cutting machine manufacturers dedicated to providing smart laser cutting equipment solutions for global users. HSG has been operating stably in more than 100 countries and regions worldwide and has a wide range of benchmark customer examples. When choosing the laser cutting machine, HSG can provide the best laser cutting solution.

How much Do You Know about Air Cutting?

Laser cutting is using a high-power density laser beam of a metal laser cutting machine to cut the material. A narrow slit composed of a series of holes comes into being with the moving of the laser beam to realize cutting. Air cutting is one of the processes of laser cutting held by a metal laser cutting machine. Do you know what is air cutting and what are its advantages?

 The principle of air cutting

In fact, the cutting principle of air is similar to that of nitrogen, which is based on the energy of the laser to melt the metal.

Air cutting is to use an air compressor to compress the air into the air tank, then remove water and oil in the air through various procedures such as filtration, cooling, and drying, and finally use a metal laser cutting machine to achieve metal cutting.

Because air contains about 21% oxygen, it can make up for the deficiency of oxygen and nitrogen to some extent while the metal laser cutting machine is working. So theoretically, air can cut all metal materials that can be melted by laser energy.

 Advantages of air cutting

The advantage of air cutting is reflected by comparing with the effect of nitrogen/ oxygen cutting. The 6KW metal laser cutting machine is used in this experiment to cut stainless steel, carbon steel, and aluminum alloy plate.

 The experimental results show that the section by air cutting is better. In speed, air cutting has a slight advantage over nitrogen cutting, no matter cutting stainless steel, carbon steel, or aluminum alloy plate.

It can be concluded that, in the case of less strict requirements, air cutting with greater cost advantage is the right choice. Meanwhile, using air cutting as an auxiliary method is also a way to greatly reduce production costs.

However, it has to take caution that when air cutting is adopted, it must be ensured that the air is filtered by the cold dryer. The air compressor and cold dryer in the metal laser cutting machine need regular maintenance.

 Besides, if the air entering the cutting head contains water and oil, the gas pipeline will be polluted in a short time, leading to the fogging of the protective lens and the performance of the mental laser cutting machine. It is wise of you to replace the protective lens in time, preventing it from the damage by the irradiation of the high-power beam.

How to Purchase Your Desired Fiber Laser Cutting Machine?

Different industries and types of materials need different metal laser cutters. In order to purchase the befitting metal cutting machine, you need to not only know your type of materials needing to be cut and cutting technology required, but also communicate well with CNC metal cutting manufacturers before purchasing sheet metal cutting machine or tube laser cutting machine. However, it is unnecessary for purchasers to fully defer to the opinions of CNC metal laser cutter manufacturers because they need to make decision based on their actual situation.

 Let's first look at what the original processing technology was.

1. The use of traditional punch processing requires a large number of molds. The parts of electrical products have a large amount of drilling sizes and different shapes, there are a lot of single-piece and non-standard products. The high mold cost and long production cycle are not conducive to the production of single-piece and non-standard products.

 2.Using a handheld jig saw to drill the hole, not only the quality of the cut is poor, the dimensional accuracy is not easy to control, but also the labor intensity is large, the noise is large, the production efficiency is low, and the saw blade is consumed a lot.

 Currently,the fiber laser cutting machine is mainly used in the electrical industry to cut thin steel plate parts in the appearance of sheet metal parts and the installation of complete sets of electrical components. Nowadays, after many electrical appliances factories adopt this new technology, they have improved product quality, reduced production costs, reduced labor intensity, improved the traditional plate processing technology, and received better production benefits.

 Compared with traditional processes, laser cutting has the characteristics of high precision, high material utilization and high production efficiency. In particular in the field of precision cutting, laser cutting has more advantages than traditional cutting. It can focus energy into a small space and use high-speed, non-contact, high-precision cutting with density energy is very suitable for the electrical industry. In the production of electrical appliances, laser cutting helps improve processing quality, save processing links and processing costs, shorten the production cycle of electrical products, thereby reducing labor and production costs, improving processing efficiency, and improving product competitiveness.

 HSG Laser focuses on the production and manufacture of laser cutting. It is a strong manufacturer of laser cutting machines. If you have any needs, please contact us ,we look forward to your inquiry!

Why Laser Cutting Machine is the First Choice for Metal Sheet Processing?

Unlike traditional flame cutting, plasma arc cutting and high-pressure water cutting, fiber laser cutting performs better in flexible processing, which is fast in cutting speed, high in cutting efficiency and has short production cycle. Considering that its cutting force is proper, sheet or tube metal will be cut in high quality. With good adaption to cutting materials, both simple and complicated elements can be cut only by once.

 In addition, our sheet metal laser cutting machines are also featured by narrow cutting joint, high cutting quality, low cutting price, high automation, easy operation, low labor intensity and pollution-free. Due to imported nesting software, the cutting materials can be typeset automatically to improve material utilization at low costs. Many mechanical experts agree that the next 30-40 years will be a golden era for laser cutting technology. This is also the development direction of metal sheet processing.
