How Proper Maintenance Affects Laser Cutting Quality

Lasers can produce some of the highest quality and most accurate cuts for fabrication. However, laser cutting can only be successful when fabricators consistently perform proper maintenance on their equipment. Without proper preventative maintenance, lasers will not perform optimally. Lack of preventative maintenance can lead to lower quality, imprecise cuts and an improperly functioning machine. Fortunately, as long as you perform regular maintenance, your laser will function optimally at all times. We’ve compiled a list of the top preventative maintenance steps you can take to keep your laser in optimal condition.

Keep Optics in Check

After performing any maintenance on the optics of your laser, you should make sure they are returned to OEM specifications. Out-of-spec optics can affect mode quality, beam quality, cutting performance, and optics life. Beam analyzers and beam profilers can address this issue. These tools are large camera-based systems that measure beam characteristics when the laser beam passes through. However, this equipment is very expensive.

Fortunately, fabricators can avoid the need for this expensive equipment by imprinting and attaching the original mode burn profiles on a piece of acrylic attached to each machine before it leaves the factory. This action allows fabricators to reference and check quickly for proper shape, size, power setting, and beam optic specifications. Advanced CNC machines are now programmed with step-by-step instructions both for performing maintenance checks and for simplifying optics checks. This is the benefit of utilizing the most modern technology. These instructions make it easy to keep your laser’s optics in check and ensure proper maintenance at all times.

Monitor Temperature

The chiller performance is important to the functionality of your laser, so it’s important to keep an eye on its temperature gauge at all times. Variations in operating temperature can affect the machine’s performance. Extreme temperature changes can even result in resonator damage, which will require a costly, time-consuming repair. All chillers have temperature sensors or temperature display to help fabricators monitor the temperature to prevent problems.

With newer control technology, fabricators can set the temperature to remain constant, eliminating the need for constant monitoring. However, even in this instance, fabricators will still need to monitor water levels in chiller units. Water can build up, especially when left idle for long periods of time, such as a long weekend. When water collects, it will build up conductivity. When the conductivity in the chiller unit is high, the machine’s self-diagnostic features will not allow the resonator to start until the level lowers. However, this operator can easily lower the chiller’s conductivity level by running the unit for a few minutes before cutting. Additionally, the operator should change the resin when necessary, which deionizes the water and helps lower conductivity.

Keep Equipment Clean

Keeping equipment clean is one of the most obvious maintenance steps to take. However, it is often the most neglectful. Especially processing areas, support slats, scrap drawers, slugs, and pallet ways. However, these areas can all contain a buildup of debris, dust, grease, and grime, which will affect the machine’s performance. A buildup on machine slats can affect slat support, causing the material to shift. This shifting can affect cut consistency, accuracy, and productivity.

Additionally, unclean processing areas, scrap drawers, dust collectors, and ducting can create a thermite hazard. Thermite is a mixture of aluminum and the oxide of another metal, typically mild steel that occurs in fabricating environments. When thermite is ignited, high temperatures can be produced that will cause significant damage to equipment. Fortunately, with regular cleaning of all parts of the laser, you can avoid these issues easily.

Fiber laser cutting machine help you save cost and energy

Fiber laser cutting machine help you save cost and energy.

The use of fiber lasers occupies a small area, the laser light source and the cooling system are smaller in size.

There is no laser gas line and there is no need to calibrate the lens. A fiber laser with a power of 2kw or 3kw only requires 50% of the energy of a 4kw or 6kw CO2 laser source to achieve the same performance.But with faster speeds, lower energy consumption, and less environmental impact.

The fiber laser uses a solid-state diode to pump molecules in a fiber. And the stimulate light passes through the core several times. And then forms a laser output through a transmission fiber to a focusing head for cutting.

Since all collisions between molecules occur in the fiber, laser gas is no need.So the energy is greatly reduce – about one third of the CO2 laser. Since the less heat is generate, the volume of the cooler can be reduce accordingly. In short, the overall energy consumption of a fiber laser is 70% lower than that of a CO2 laser, with the same performance.

The edge of the cover film cut by this laser system is neat, smooth, smooth and free of burrs. The burrs and glue after punching will be near the windows where the windows are inevitably by molds, etc. Such burrs and glues are difficult to remove after being laminate on the bonding pads. And will directly affect the subsequent Plating quality.

The characteristics of advance manufacturing technologies such as high flexibility. High precision, and high speed can enable circuit board manufacturers to change the traditional processing. And delivery methods of flexible boards in terms of technical level,economy, time, and autonomy.

Fiber laser cutting machine help you save cost and energy.

Features

1. The advantages of laser cutting.

2. The laser has three main functions in the manufacturing process of the flexible circuit board.

3. Use laser cutting directly according to CAD data, which is more convenient and faster, and can shorten the delivery cycle greatly;

4. It does not increase the processing difficulty due to complex shapes and tortuous paths;

5. When the cover film is opened, the edge of the cut cover film is neat, smooth, smooth and free from burrs. The use of molds and other machining methods to open the window will inevitably lead to burrs and overflow after punching near the window.

6. Flexible plate sample processing often results in the change of the cover film window due to the customer’s need to modify the line and pad positions. The conventional method requires the replacement or modification of the mold.

With laser processing, this problem can be solve, because you only need to import the modified CAD data, you can quickly and easily process the film you want to open the window, and you will win the market in terms of time and cost. Competition opportunities.

7. High precision laser processing is an ideal tool for flexible circuit board forming processing. The laser can process the material into any shape.

8. In the past mass production, many small parts were formed by pressing using a mechanically hard stamped mold. However, the large wear and long lead times of the hard dies are impractical and costly for the processing and forming of small parts.

Laser cutting machine basics These six core components—Winnie

/in , /by

Laser cutting machine basics These six core components

In the metal processing, fiber laser cutting machine has gradually replaced the traditional technology with its advantages, and has become a weapon in the metal processing industry.
But even if it is also calle fiber laser cutting machine, the processing efficiency and effect of different equipment in the inside will be very different. For fiber laser cutting machine, the six core parts must be seen when purchasing.

1. Fiber laser

Lasers are the „power source“ of the core of laser equipment, just like automotive engines, and are expensive components in fiber laser cutting machines. At present, the imported brands of fiber lasers in the market include German IPG, ROFIN, British SPI, American coherent, etc. With the development of technology, domestic laser brands such as Ruike and Chuangxin have also emerged, and they are gradually recognized by the market with high cost performance.
For a long time, China’s lasers have basically relied on imports, which are expensive and have long lead times, resulting in high prices for high-power fiber laser cutting machines. The emergence of China’s fiber laser manufacturers has broken the monopoly of foreign companies in the field of lasers, and directly lowered the price of imported products.

2, cutting head

The cutting head is a laser output device of a fiber laser cutting machine, which is composed of a nozzle, a focusing lens and a focus tracking system. The cutting head of the laser cutting machine will walk according to the set cutting trajectory, but the height of the laser cutting head needs to be adjusted and controlled under different materials, different thicknesses and different cutting methods.

 

3, CNC system

The control system is the leading operating system of the fiber laser cutting machine, which mainly controls the machine tool to realize the movement of the X, Y and Z axes, and also controls the output power of the laser. Its quality determines the stability of the operation performance of the fiber laser cutting machine, and the cutting effect can improve by software control. Currently used Beckhoff CNC system, PA numerical control system, Falyan card system, etc.

 

4, the motor

The motor of the laser cutting machine is the core component of the motion system. The performance of the motor directly affects the processing effect and production efficiency of the product. At present, the commonly used motors include stepping motor and servo motor, which are configure according to the industry type and product type of the processing object. Suitable motor.
Firstly, Stepper motor: It has fast starting speed and sensitive response, and is suitable for engraving and cutting processing. The price is lower. Stepper motors have many brands and different performances.
Secondly, servo motor: fast moving speed, smooth movement, high load, stable performance; smooth edge processing and fast cutting speed; high price, suitable for industries and products with high processing requirements.

 5, machine Bed

Mostly fiber laser cutting machines have very high requirements for machine tool stability. So at present, mainstream machine tools on the market include gantry, cantilever, beam, etc. Different machine tools have different functions. For example, beam type machine tools are mainly use for material cutting by large manufacturers. And also for specific fields, such as three-dimensional fiber laser cutting. Mainly used in the automotive industry.

 

6, laser lens

Laser lenses are use in the whole fiber laser cutting equipment. Many optical devices contain laser lenses. Different lenses have different functions, such as full-reverse lenses, semi-reverse lenses, and focusing lenses.
In general,The quality of the lens directly affects the output power of the laser. Which also affects the performance of the whole machine. The same lens is also divide into domestic and imported. The life and cutting effect of domestic lenses are not as good as imported lenses. But the price is far cheaper to import lenses.

Plate fiber laser cutting machine different powers:Charry XT LASER

/in , /by

Plate fiber laser cutting machine different powers

Plate fiber laser cutting machine different powers.

In thin sheet cutting field, most users like to use fiber laser cutting machine.

But what is sheet, what is plate, what is cut deal? Do you know how to distinguish so many different metal plate?

1.Thin Plate(take carbon steel as example)

Sheet Thickness:≤4mm

Sheet means metal plate less than 4mm, usually we call it thin plate.

Mild steel and Stainless steel as two main cutting material,

most company select laser cutting machine on this field.

750W fiber laser cutting machine is popular in this field.

2.Medium Plate(take carbon steel as example)

Thickness: 4mm~20mm

Also we call it middle plate, 1kw & 2kw laser machine is popular in this field.

If carbon steel plate thickness under 10mm, and stainless steel is under 5mm,

1kw fiber laser cutting machine is suitable.

If plate thickness is from 10~20mm,2kw machine is suitable.

3.Heavy Plate(take carbon steel as example)

Thickness: 20~60mm

Usually we call it thick plate, it need 3kw laser machine at least.

Fiber laser cutting machine is not very popular in this field.

Because when the power is more than 3kw, the price is much higher and higher.

Most metal fabricators will choose a plasma cutting machine to finish the work.

Usually when cutting heavy plate, most customers choose plasma cutting machine.

But its cutting precision is not very high.

4.Extra thick plate

Thickness: 60~600mm. some country could reach to 700mm

No fiber laser cutting machine could used in this field.

On thick plate cutting fields, co2 laser cutting machine and plasma cutting machine have big advantage than fiber laser.

These kind of machine have very good complementary relationship.

Some large metal fabricating company have all these machine in order to meet different cutting demand.

Correct operation for fiber laser cutting machine:Charry

/in , /by

Correct operation for fiber laser cutting machine

Correct operation for fiber laser cutting machine.

Fiber laser cutting machine is a high-tech large-scale machine in the division of machinery.

This kind of machinery is very expensive and the demand of technicians‘ operation level is also very high.

In the cutting process, this machine must be always maintained in order to extend the lifespan.

Today we will talk about the use and maintenance skills of this machine.

First, let the steel strip stay tight at all times.

The steel belt plays a very important role in the transmission of the laser cutting machine.

The steel strip is made of steel,if the steel is not tightened during use, it will easily being cut.

Out of the track, even the steel strip may cause slipping, which poses a great threat to the safety of the workers,

so no matter when or where, the steel belt must be kept in tension.

Second, often check the angle of the tool

Because the most important part of the whole fiber laser cutting machine is the cutting head.

If the angle of the cutting head shows a certain deviation,

the final precision of the cut object will be less accurate during the cutting process.

Third, often sweep dust inside of the machine.

Since the laser cutting machine directly vaporizes the metal surface during cutting,

a lot of dust is often generated on the surface and inside of the cutting machine.

We should always suck the dust out with a vacuum cleaner to ensure zero inside the machine.

The parts are spotless, so that can operate normally.

Fourth, parts and components should be treated frequently with lubricating oil.

We need to lubricate the racks, rails and many cutting machine parts from time to time

so that they can ensure that the gears are very precise during operation.

In this way, the mechanical operation will be in the normal running track,

and the precision of the cut products will be higher.

In addition to the daily maintenance of the fiber laser cutting machine,

we must strictly check the parts when we buy the machine,

so that the mechanical damage can be eliminated from the root.

At the same time, if any parts are damaged during the use of the machine, it must be replaced in time,

which is a kind of protection for the machine, and the ideal cutting effect of the laser cutting machine.

Only after the above two points are achieved can the service life of the cutting machine be extended.

You are looking for fiber laser cutting machine?

You are looking for fiber laser cutting machine?

If you are user of fiber laser cutting machine, or you are going to buy fiber laser cutting machine,

maybe following information is helpful to you.

Water Chiller of Fiber laser cutting machine:

Question 1:What kind of water pour into chiller?

Answer 1:Water cooler inside need to add purified water or distilled water

Question 2: How long need to change water?

Answer 2:If the quality of pure water is not particularly good,

it is recommended to change the water once every 2 weeks. Good quality water, once a month for water.

Water inside do not need to add special substances.

However, if for customers, local weather is very cold,

you may need add antifreeze or industrial alcohol into the water-cooler,in order to avoid freezing.

When the weather is cold, if you do not use water chiller often , please pour out all the water timely.

Questions 3:What is the oxygen consumption of the 10 and 20 mm carbon steel laser 3000w?

In China, one bottle of Liquid Oxygen is 50$/bottle,

Standard oxygen bottle is 40L/bottle , when 3000w cut 10mm and 20mm carbon steel,

air pressure is lower, about 1-2kg, so one 40L bottle of Oxygen can be used for about 1-1.5 hours.

NOTE: For example. In China, one bottle of Liquid Oxygen is 50$/bottle,

Standard oxygen or nitrogen gas bottle is 40L/bottle

1mm Carbon steel 40L/40minutes

2mm Carbon steel 40L/50minutes

3mm Carbon steel 40L/60minutes

4mm Carbon steel 40L/70minutes

5mm Carbon steel 40L/80minutes

6mm Carbon steel 40L/90minutes

8mm Carbon steel 40L/110minutes

10mm Carbon steel 40L/130minutes

For carbon steel, The thicker metal you cut, the less Oxygen pressure you need,

because if use higher Oxygen pressure for thicker metal sheet, it will be burned.

1mm stainless steel 40L/30minutes 20

2mm stainless steel 40L/30minutes

3mm stainless steel 40L/30minutes

4mm stainless steel 40L/30minutes

Generally speaking, the thicker metal sheet, the higher Nitrogen pressure it needs.

For example, if cut 1mm ss, use 10kg Nitrogen. If cut 4mm ss, need 20kg Nitrogen.

But in order to keep high cutting speed for thin metal sheet , such as 1mm.

So we suggest client to adjust same pressure, all of them are 20kg, in this way,

it can not only make sure of high speed of cutting thin metal sheet, also it can make sure of cutting thick metal sheet.

Any questions,we can have a further discussion.

Auxiliary gas of fiber laser cutting machine-Teresa

/in , /by

Auxiliary gas of fiber laser cutting machine.

Auxiliary gas of fiber laser cutting machine.

When cut the fiber laser cutting machine, different cutting gases according to the material of the cutting plate. The choice of gas and pressure has a great impact on the quality of fiber laser cutting machines.

Effect of cutting gas and pressure on cutting quality

1) The cutting gas helps to dissipate heat and assist combustion.And blows off to obtain a better quality cut section.

2) When the pressure of the cutting gas is insufficient, the melting will occur during cutting, and the cutting speed cannot meet the production efficiency.

3) When the pressure of the cutting gas is too high, the influence on the cutting quality: the cutting surface is rough, and the slit is wide; at the same time, the cut section is partially melted, and a good cutting section cannot be formed.

The effect of cutting gas pressure on perforation.

1) When the gas pressure is too low, the laser does not easily penetrate the cut sheet, and the punching time increases, resulting in low productivity.

2) When the gas pressure is too high, the penetration point is melted to form a large melting point, which affects the quality of the cutting.

3) When laser drilling, generally, a higher gas pressure is to the punching of the thin plate member.

And a specific punching method for the punching of the thick plate member.

Tthereby eliminating the disadvantage of the low air pressure to protect the lens.

4) When the laser cutting machine cuts ordinary carbon steel, the thicker the material, the lower the pressure of the cutting gas. When cutting stainless steel, the cutting gas pressure increases relatively with the thickness of the material. In short, we need choose cutting gas and pressure during laser cutting according to the actual situation during cutting. In specific applications,Select different cutting parameters according to the specific conditions.

Relationship between cutting speed and cutting effect of fiber laser cutting machine-Anne

/in , /by

Relationship between cutting speed and cutting effect of fiber laser cutting machine

The choice of speed is very important when the CNC fiber laser cutter is on work. If the speed is too slow, the effect will affect production.

If the speed is fast, but the quality is not good, it will not be worth the loss. In fact, the fiber laser cutting machine is not so simple in terms of control speed.

The cutting speed is often tested according to a range provided by the technician to find a suitable cutting speed.

The cutting speed is also different because of the metal thickness, the composition of the metal, and the difference in ductility and thermal conductivity.


1.Properly improving the speed of the laser cutting machine not only improves the quality of the slit, but also makes the slit narrow and flat, and also reduces the deformation of the slit.

2.If the cutting speed is too fast, the line energy of the cutting will be lower than the required amount.

During the slitting process, the blowing cannot quickly blow off the molten material, which will result in a large amount of back drag, which affects the integrity of the slit. Even the case of secondary processing may occur.
3.If the speed is too low, the cutting position will be exposed to the high temperature of the laser for a long time, which not only causes the cutting seam to become large, but also may affect the appearance of the slit due to too much heat conduction. Forming the phenomenon of hanging slag.
4.At very low speeds, the slit melts too much, the slit is wider, and even the arc is extinguished, and the cutting cannot occur.

Therefore, the cutting speed will affect the cutting quality, not just from the cutting speed,

we hope everyone should be careful when operating the optical fiber laser cutter.
If you want to learn more when operating the machine,just leave us message,our engineer will help you in 24 hours.

Hope it is helpful for you ,if you have any questions of machine,please feel free contact us.
