The degaussing of parts in laser cutting

Over the past two decades, the sheet metal and boiler making industry has evolved to become more and more competitive, orders are arriving later and later, lead times are getting shorter, fierce competition is forcing the industry to compete with ingenuity in order to reduce production costs and to be able to offer advantageous prices without impacting quality. Machine tools have also evolved, they have become real jewels of technology, fully automated and offering extraordinary performances, these machines represent important investments for manufacturers but are nevertheless necessary for anyone who wishes to remain competitive. 

In this context, any optimisation in terms of productivity is welcome, and there is one problem in this area that can be particularly costly and that all users of laser cutting machines are confronted with, which is the degreasing of parts.

What is part degreasing?

During laser cutting operations, micro-junctions are made that keep the cut parts attached to the sheet metal skeleton. Their main function is to keep the parts flat in order to avoid a collision with the cutting head, which could seriously damage the machine. They also serve to prevent the parts from falling under the cutting table and possibly getting lost or damaged. In an automated machine, the micro-junctions also allow the unloading forks to retrieve the cut sheet in a single block for storage while awaiting de-stripping.

De-bonding is the action of unhooking the cut part from the sheet metal skeleton by breaking the micro-junction. This operation is usually carried out manually by an operator and can be particularly time consuming if many small parts have been cut, especially after a night or weekend of automatic machine operation. This is a dry loss of productivity as it takes at least one person full time, and cannot be done in hidden time due to its length.

How to speed up the process of removing parts?

There are several ways to reduce the time spent on degreasing metal parts. The most effective, but also the most expensive, is to acquire a fully automated laser cutting centre. The latest generation of laser cutting machines offer several automation options, from loading and unloading, to sorting the cut parts by a system designed to collect the parts and place them in different bins according to their shape. This is obviously the most efficient solution and will have a significant impact on your productivity. That said, it is necessary to have large production volumes in order to amortize the high cost of this type of machine, which can exceed one million euros! It is therefore not a wise investment for all companies, which is why several other systems exist. 

Among them, one solution stands out because it allows to reduce the degreasing time significantly and at a lower cost, it is the Rhino Hammer gun. 

The Rhino Hammer is a very simple and economical pneumatic hammer gun that allows you to blow out micro-junctions by simply passing the polyurethane tip over the parts. Thanks to this system and its impressive impact rate of 1,000 strokes per minute, it is possible to reduce the time spent on degreasing by over 60%. Of course, this productivity gain will quickly translate into significant economies of scale as it is much more affordable than other options. In addition, the polyurethane tip ensures that no impact marks are left on the parts. For our team, this is definitely the best value solution on the market to optimise your post-cut handling operations by reducing the time spent on part removal.
We found this solution so interesting that we recently decided to add the Rhino Hammer to our catalogue. We are now able to offer this product to all our customers!

precision leveler for metal

Problems with flatness? Think precision leveler!

What is the purpose of a precision leveler ? First of all, it is important to know that your parts can be deformed as a result of laser, plasma or punching operations. If this is the case, it is because the temperature contrast generated by this type of technology releases the stresses inherent in the metal. This causes the phenomenon of cambering, also known as tiling. Even worse, your sheets may be tiled or bent before the laser cutting process.

Although quite common, this phenomenon can be detrimental to your day-to-day production. Indeed, whether it is on sheet metal or on already cut parts, it can cause a loss of productivity in the order of 15 to 25%, or even more if you use welding robots.

In addition, touch-ups may be necessary in order to regain optimal flatness. These operations can generate a lot of scrap when it is impossible to recover the defect, causing a loss of profitability. This problem is all the more present as the length of the parts, or sheets, is important.

Rather than manually straightening your parts to meet your customers' requirements, you can optimize their stability with a simple leveling operation lasting about 2 minutes. The purpose of this operation is to subject the sheet or part to several alternating bending operations applied by small cross-section flattening rollers. The effect of these operations will be to eliminate residual stresses and obtain a perfectly flat part ready for machining in record time, without the need for time-consuming and damaging rework that would be detrimental to your profitability.

The efficiency of a precision leveler with servo-hydraulic motors

The gain in profitability can easily be calculated. For example, if you manually straighten 10,000 parts per year, an operation that can take up to 30 minutes per part, this means that your operators spend 5,000 hours a year straightening.

On the other hand, ifyou reduce the operation time to 2 minutes per piece, your operators will only spend 333 hours a year for a better end result. An exponential gain that doesn't even take into account the improvement in the stability of your parts, which will allow you to save time on each of the steps after cutting.

In general, 2 operators are required to perform manual straightening of parts. To sum up, they will cost you around 30 euros each per hour, i.e. a total of 60€/h x 5,000h = 300,000€ / year

On the other hand, if you equip yourself with a precision leveler with servo-hydraulic motors, the operation will only cost you 60€/h x 333 h = 19 980€ per year. This means a potential gain of more than 280 000€ each year.

This is a theoretical example to illustrate our point. Everyone must indeed be aware of the importance of these deformation problems, and not hide the fact that the hidden costs are potentially significant.

laser tube machine

All about tube laser cutting

With our previous blog posts, you already know the various fields of application offered by laser technology. Among these applications, we often talk about 2D laser cutting and the laser engraving on wood. But that's not all, it also includes laser tube cutting , which has been very successful in recent years.

But why such a development of this market? Most of the time, companies wishing to cut tubes and profiles use traditional methods, such as cutting with hand saws, grinding wheels or gas welding. These methods have many disadvantages, being more tiring and time-consuming for your teams. Faced with this obvious observation, laser tube cutting machines were born! 

Reduction of production times

First of all, as with the 2D process, laser tube cutting offers a more cost-effective solution compared to conventional methods: sawing, drilling or milling of metal tubes. In detail, these machines are equipped with a rotary axis, allowing a specific handling of the parts. This unique design guarantees optimum cutting qualities and a considerable reduction in production times.

The advantages in a few points: 

  • More than 70% time reduction on each machined tube.
  • Parts can be assembled 2x faster.
  • Possibility to continue to use other production tools at the same time: 2D laser cutting, milling machine, saw...
  • Process large serial customer orders more efficiently.
  • Possibility to work on much more complex tube shapes than with manual methods.

As you will have understood, the laser tube offers significant efficiency and production flexibility, opening up interesting possibilities for manufacturers to create new products. An opportunity to constantly respond to the needs of the market in real time! As you will have certainly noticed, the tube is present in many metal constructions.

Finally, the powers of these laser machines can be increasingly higher thanks to the innovations proposed by the manufacturers. Today, these machines can reach up to 5kW in order to perform cutting on tube diameters ranging from 12 to 610 millimetres. As for the length of the processed tubes, they can reach 14 metres for the largest machines.

metal tube construction

Fiber at the service of the tube laser

Of course, you can't afford to miss out on the latest innovations on the market! Manufacturers of tube laser machines have understood this, quickly deciding to integrate fiber laser sources into their production tools. Nevertheless, for more flexibility, most manufacturers still offer the choice between fiber and CO2 machines.

Of course, the main advantages of this technology remain similar to flatbed laser cutting machines :

  • Possibility of cutting the tube on many materials, including copper and brass.
  • Lower energy and maintenance costs compared to CO2 technology.
  • Absence of several spare parts.

In conclusion

In conclusion, it is obvious that laser tube machines still have a good margin of progress, similar to the fiber laser machines flat, now up to 20kW of power! From the point of view of the equipment itself, this will require increasingly fast cutting speeds and complete automation thanks to the phenomenon of "flattening".industry 4.0This is a new way of organizing productions, particularly thanks to digitalization.

Moreover, the collection of this machine data by the software in place will allow tomorrow's machines to continuously improve according to the expectations of each company. This is where the most interesting added value for the future of thelaser industry lies.

The importance of metal deburring in laser cutting

Today, as you know, there are a multitude of tools for metalworking. In our case, we are particularly fond of laser cutting. Machines on which we have been performing maintenance since 2002. Indeed, they offer a certain flexibility, speed and precision in your production compared to other machine tools. It is certainly a heavy investment, but it will be very profitable for your company over the years.

In addition to laser cutting machines, we can also mention press brakes, plasma cutting tables, water jet cutting tables and deburring machines. In this article, we will focus on the latter production tool. A machine tool dedicated to a perfect metal finish, ideal for increasing the quality of your production.

All you need to know about metal deburring

The first question you need to ask yourself is a legitimate one: What exactly ismetal deburring? As the name suggests, it is the process that comes after laser cutting. This operation consists of removing burrs, splashes and dents from the edges of your metal part. Simply put, it's all the little imperfections that separate the edges of your part from a completely smooth and shiny surface. That being said, these burrs are generally less present on laser-cut parts compared to other metalworking machines. Obviously, the greater the thickness of the metal being cut, the more burr will be present. This makes perfect sense.

Demanding customers in search of the best quality!

In a booming laser cutting market, there is obviously more and more competition. In particular, many subcontractors are equipping themselves with very powerful fibre laser machines to keep up with the influx of orders. Nevertheless, faced with these numerous players, customers sometimes find it difficult to make a choice for their service providers. For subcontractors, one argument makes the difference: production quality!

We now frequently see manufacturers who no longer hesitate to internalize laser cutting directly in their factories. As an example, we can cite our customer Citynox and its purchase of a EAGLE fiber laser machine 15kW. It is for the moment the most powerful machine installed in France (September 2020). A machine which thus largely exceeds the performances of those of the subcontractors!

In view of this high customer demand, the deburring process is becoming more and more important. Hence the growing interest in deburring machines, machines for clean metal finishing, such as the one of our partner COSTA Levigatrici for example.

How deburring machines work

Choosing a deburring machine really makes it possible to simplify and speed up the finishing of your parts after the metal cutting phase. It saves your teams from having to use belts, papers or sanding discs. Indeed, these "classic" deburring processes are much less efficient, but above all much more time-consuming and exhausting! With a metal deburring machine, all you have to do is put your production parts directly into it to see it come out as smooth as possible. All in record time! With a perfect quality of your parts, your customers will always be satisfied, which will help you to retain them in the long term. An important focus, especially for VSEs and industrial SMEs!

What material should be used for woodcutting?

Woodcutting: The inventory of usable material

Wood engraving is an activity that has many uses. In addition to the artistic interest, it allows to carry out markings on various wooden supports. Achieving the desired result in this respect requires adequate, reliable but also practical equipment.

Numerous hand tools can be used to make markings on wood. This is notably the case of the chisel. It is also possible to achieve the desired result by working the wood with heat.

In addition to manual tools, the use of automated equipment also makes it possible to engrave on wood. Faster and much more reliable, this type of equipment makes it possible to achieve high performance in wood engraving.

Woodcutting equipment: hand tools

The engraving chisel

The basic tool for woodcutting is the chisel. Manual, it is characterized by a rather difficult grip and requires a good training to present interesting results.

On the register of precision, the chisel does not offer great performance, unless you have experience and mastery bordering on mastery. This rudimentary tool allows relatively coarse engraving with a low level of detail and nuance.

The soldering iron

The soldering iron is a material that allows pyrography: the engraving is made on wood by means of heat. This tool is characterized by a level of fineness much higher than that of the chisel.

The engraving pen

The engraving pen is a manual tool powered by electricity. It can be equipped with different sized cutters to produce various impressions on the wood. The material offers a particular level of comfort because it allows you to work on wood with a lot of flexibility.

The variety of available strawberries makes it possible to create a detailed work with many nuances.

Wood engraving: The use of laser

In addition to metal cutting, laser technology allows the processing of many other materials. Laser cutting of wood is one of the known applications of the laser. But this technology is not limited to this use.

The laser engraver

This digital and fully automated device allows the engraving of wood using the laser. Light and relatively small in size, it offers the possibility of making an impeccable print on the wood, based on the models transmitted to it.

The laser engraver thus makes it possible to carry out personalized and high-quality engravings on the wooden support.

Trotec Laser  or our partner Gravotech are companies specialising in this type of equipment. They offer a wide range of equipment and tools for both professional and personal use.

The mode of operation

As a digital device, the laser engraver receives engraving instructions from another device. This can be a smartphone, tablet or computer. Various connection modes allow the transmission of the content or pattern to be engraved on the wood.

The operation of the automated wood engraving equipment is ensured by a USB connection, which allows great flexibility in its power supply.

The different types available

The available laser engravers are of various types:

  • The laser of a CO2 engraver is formed by a mixture of CO2 agitated by a source of electricity. Its beam is of good quality and it is used in most models;
  • The fiber laser has a much higher power output and is also more resistant and durable in use;
  • The crystal laser is known for its solidity. Although it is not as durable as the fibre laser, it can be used to mark a wide variety of materials.

The interest of the laser for engraving on wood

The main advantage of using a laser engraver to engrave wood is its speed. The device can reproduce a pattern or design with astonishing speed, whereas hand work is slow and laborious.

Another positive aspect of the laser engraver is the fidelity of the rendering. The result of the work is always extremely precise and of excellent quality, provided that the device is used properly. You can click Here to read an article about laser cutting.

The wide range of possibilities is also an advantage that justifies the use of lasers. The nuances, details and fineness of the reproduction make it a woodcutting material that allows a high level of creativity to be achieved.

servilase laser cutting consumable

Consumables for laser cutting

Consumables directory for laser cutting machines

Today, we present you the laser cutting consumables. Small parts, which are essential to ensure the proper functioning of your machine. Presentation.

What is a consumable for laser cutting?

When we talk about consumables for laser cutting, we are talking about nozzles, protective windows, lenses or even ceramics. Parts that allow your laser machine to work properly for the production of your customers' parts.

As the name suggests, these elements have a long life and use. Of course, in order to ensure production that meets your expectations, it is essential not to neglect the quality of these consumables. Moreover, with better quality, you can logically use each of these parts for longer. Significant savings, especially in the long term for your company. 

As you will have understood, consumables are important to consider when you need to choose your laser cutting machine !

The main types of laser consumables

Cutting nozzle

  • The laser nozzles are made of copper, which is the last part of the cutting head that is in contact with the sheet metal. It injects gas pressure into the cut, allowing the metal to be cut. For a better durability of your nozzles, consider buying chrome nozzles.

Protective window for a fibre laser

  • Protective windows are consumables that are only found on the fiber laser machines. They protect the focusing lens(es) of the cutting heads, thus preserving their qualities and a durable cut.

Ceramic laser cutting head

  • Ceramics are a terminal component of the profile tracking system during laser cutting. They are located at the end of the head, acting as a support for the nozzle. 

Focal lenses for laser cutting

  • Finally, the lenses for laser cutting are located in the head and allow the beam to be focused. A focal lens in good condition ensures optimal laser beam quality, allowing clean and sharp metal cutting. 

Laser cutting consumables at SERVILASE

In response to our customers' expectations, we have decided to develop partnerships with many suppliers of consumables for laser cutting. Of course, as outlined above, we have focused above all on the quality of these parts. A long process that today allows us to be sure to provide the best to our customers.

With a field of expertise in laser cutting machines EAGLE laserIn addition, we ensure that we always have a large stock of lenses, ceramics, nozzles and protective windows for these brands of fiber laser and CO2 machines.

Nitrogen generator for laser cutting

In this article, we explain the growing interest of the nitrogen generator for the laser industry. An equipment which allows a perfect autonomy of its laser production. But also and above all, a significant reduction in your costs. Explanations.

The importance of nitrogen in laser cutting

First of all, to operate laser cutting machines must be supplied with electricity and gas. With CO2 laser technology, a mixture of gases (nitrogen, helium and CO2) is injected at the laser source. This mixture is used to generate the machine's beam. For the fiber laser, it is simply a laser diode that will directly generate this beam. You will have understood it, we use mainly two gases for laser cutting: Nitrogen and oxygen.

With fibre laser technology, the use of oxygen is even becoming increasingly rare. For example, some of our customers equipped with a machine EAGLE laser, reserve the use of oxygen for cutting thick layers only. These technological advances logically allow a significant reduction in energy costs. A profitable argument, which amply justifies a transition to fiber laser. To accompany this transition, we offer our customers the possibility of generating their own nitrogen.

The nitrogen generator: an all-in-one solution

Faced with this observation, many companies such as Isocell have decided to expand their range of nitrogen generators. An equipment that automatically feeds the nitrogen tank for laser cutting.

Thanks to our nitrogen generators, you are perfectly autonomous and are no longer subject to gas delivery problems. Moreover, you have a major advantage in complex economic situations, such as the VID-19 health crisis.

Of course, to be efficient it is important that your nitrogen generator is adapted to the consumption of your laser production, which is itself variable according to the periods.

Specific case of the use of a nitrogen generator

To illustrate our point, we will demonstrate the efficiency of the Isocell nitrogen generator with concrete figures.

Indeed, thanks to our model with a production capacity of 27 m3/h and a tank storage capacity of 480 Nm3, it is possible to cut stainless steel up to 2mm continuously without interruption! However, it will be important to evaluate your average consumption over a production day, knowing that your tank fills up preferentially at night. In order to avoid stoppages in your production.

Of course, if you wish to have a personalized study according to your needs, do not hesitate to contact us.

Citynox invests in the dynamics of the Eagle fiber laser!

Great news at the beginning of the year 2020! The company Citynox based in Alès (30) has just chosen our brand, EAGLE laser, for his next fiber laser investment. A choice that was made for our brand for its capacity for innovation, its rapid evolution worldwide and the intrinsic performance of our machines.

Indeed, today, EAGLE is present in many countries throughout Europe, but also across the Atlantic with already 4 15kW machines in the USA!

A high-performance fibre laser machine for an ambitious project

Citynox, as its name suggests, is a company specialising in working with stainless steel in all its forms. It is moreover one of the most respected French companies in this field. In order to be even more flexible with regard to the requests of its customers, the company is able to create everything with stainless steel. No project is too complex for their teams! Thanks to this expertise acquired over 4 generations, they respond to the different actors and creators of urban spaces: architects, designers or installers...

As part of a major project, the company needed to invest in new laser cutting equipment. Of course, in order to remain in a constant innovation of its means of production, the company logically turned to fiber laser technology. Moreover, the choice of a high cutting dynamics was an indispensable variable for the manager of the company Citynox: "Eagle was our preferred choice, because Citynox must always remain at the forefront of production technologies, and Eagle is the leader in this field. Eagle is to cutting lasers what Tesla is to cars."

With this in mind, Citynox chose the iNspire range, with an acceleration capacity of nearly 6G and a cutting speed of up to 150mm/min.

Finally, in order to optimize production capacity, it was important to combine this high dynamic with power adapted to the volumes of parts to be produced. The aim was to optimize the cost of this project. Following multiple strategic reflections, the 8kW power was chosen. It will therefore be the most powerful machine installed in France to date for our brand!

Flexibility, EAGLE Laser's core competence

Given the scope and multiple deadlines of the project, it was important for Citynox to be able to count on the production of this new laser machine starting in April 2020! A delay of only 2 months for manufacturing, delivery and installation.

A challenge that is entirely possible, thanks to a clear improvement in the manufacturing lead times of our machines. Indeed, the worldwide success of the group has enabled the EAGLE teams to double the production plant at the headquarters in Walcz, Poland. We are now able to offer lead times twice as fast compared to 2019, i.e. a machine put into production in only 2 to 3 months. Of course, these lead times may vary slightly, depending on the configuration chosen for the machine.

Industrial Laser Logbook - #1

Since our creation, we have been working to create a relationship of trust with each customer, especially around their industrial laser cutting issues. To do this, we strive to have a long-term vision of all the accompaniments carried out around our service provision and products. Today, we are proud to say that many of our customers have been working with us since the creation of SERVILASE. That's more than 15 years! 

The complex problems of the industrial laser

One of these long-standing customers is a world-famous steel group: ThyssenKrupp AG. Today, the company calls upon the SERVILASE team for a complex industrial laser problem.

No laser cutting as such, but a complex process using laser technology, such as Trumpf laser sources for example. Of course, these machines are custom-made for the production sites of the German industrial group. In this approach, our team has an expert role from the design, then the implementation of the process and finally the maintenance and optimization, in order to achieve better results every day. 

Discovering the Indian Laser Industry

Thanks to the confidence and experience accumulated in recent years on this type of machine, ThyssenKrupp has chosen SERVILASE for the development of this industrial laser process on another site of the group, in India. A proof of confidence shown by a group in full international expansion. 

José Manuel MENARGUES, President of Servilase and an expert in this laser process, then went to the Nashik site near Mumbai in India. Once on site, he was in charge of installing and starting up the machine. An enriching experience from a technical and human point of view, which allowed us to develop the network of our SME and, at the same time, to discover a totally different working culture.

industrial laser team

Two weeks of intervention were necessary to make all the adjustments, launch production and optimize the results. As for the French site and their laser machines, our team will now be in charge of the maintenance and optimization of the results.

It will therefore be necessary to travel to India 2 to 3 times a year to carry out the necessary operations. Great future prospects for SERVILASE, in order to export our knowledge of industrial lasers internationally.

First Warcom laser machine in France!

As mentioned since the beginning of the school year in September, we now represent 3 laser machine brands in France. The objective of this range is to offer equipment adapted to the needs of our customers and to have a 360° vision around the laser. (laser range, deburring machine, nitrogen generator and press brake)

In this range is the Italian brand Warcom. A historical manufacturer that did not yet have a fibre laser machine in France. It is now official, our client, the company EDM-SODUSI has just ordered a W-FIBER 3kW from us.

The company located near Voiron (38) is specialized in the stamping and cutting of all types of metals (steel, stainless steel, aluminium, brass...).

It employs nearly 100 people and has trusted partners for the provision of additional services. This machine will be delivered and installed in February 2020. It will be the first Warcom laser cutting machine in France!

A relationship of trust for more than 15 years

This new investment represents a mark of confidence from our client EDM-SODUSI and its president Eric Marciano towards the SERVILASE team. Indeed, we support this company on the laser maintenance of their Bystronic machine for over 15 years. A long-standing customer with whom we have built a relationship of mutual trust, accompanying them on their daily laser problems.

Today, we are delighted to have been able to offer a product and customer experience that meets their expectations and requests.

Good prospects for the future 

This new machine, equipped with fiber laser technology, will allow EDM to benefit from significant economies of scale. Indeed, between maintenance and reduced energy consumption, we no longer present the multiple advantages of this technology, in comparison with CO2 technology! Thanks to this new laser equipment, the company will be able to enter a new dimension, thanks to optimized productivity.

Finally, this success confirms our choice to build a laser range for our customers. Now our objective is clear. It is to serenely support our customers and all companies wishing to start their transition to fiber laser.
