Laser cutting works by having focused and precise laser beam run through the material that you are looking to cut. Initially, the laser is used to pierce the material with a hole at the edge. And then the beam is continued along from there.
The laser being used essentially melts the material away that it is run over. so is more like melting than cutting. This means it can easily cut light materials such as cloth up to tougher metals and gemstones such as diamonds.
You can use either a pulsed laser beam or a continuous wave laser beam, with the former being delivered in short bursts while the latter works continuously. You can control the beam intensity, length and heat output depending on the material you are working with, and can also user a mirror or special lens to further focus the laser beam.
Laser cutting is a highly accurate process, thanks to this high level of control that you are offered. Thanks to this, slits with a width as small as 0.1mm can be achieved when using the laser cut process.
There are three main types of laser cut:
C02 laser cutting
C02 laser cutting process is done using a gas laser. The gas in question is a carbon dioxide mixture which has been electrically stimulated. C02 laser cutting is most often used on non-metal materials as they have a wavelength of 10.6 micrometres.
Crystal laser cutting
Crystal laser cutting uses nd:YAG (neodymium-doped yttrium aluminium garnet) and nd:YVO (neodymium-doped yttrium ortho-vanadate) lasers. These are crystals which belong in the solid state group of lasers, and have the same wavelength as fiber lasers, around 1.064 micrometres. This means that they are useful for both metals and non-metals.
However, this type of laser machine is made up from expensive pump diodes, which can be costly when needed to be replaced; typically, after 8,000 – 15,000 hours of use. The crystal used also has a much shorter service life than that of a fiber laser.
There are other types of laser cutting process, such as gas laser cutt
Fiber laser cutting
This type of laser cutting process is completed using a fiber laser, the type of lasers that we have here at SPI Lasers. Like the method of crystal laser cutting above, fiber lasers belong to the solid state group too.
A beam is created using a ‘seed laser’, which is then amplified using glass fibers and pump diodes. They have the same wavelength as above, 1.064 micrometres. This means that the laser beam for a fiber laser is roughly 100 times greater than that of a C02 laser when it comes to intensity. It also means that they can work with both metal and non-metal materials.
A fiber laser is the most useful of the three laser types. Alongside the benefits listed above, they are often maintenance free, require much cheaper replacement parts, and have a much longer service life of around 25,000 usage hours.

There is so many different metal cutting equipment in the market. So it may let us confused when choice suitable machine. In this case, how can choose suitable laser cutting equipment or other cutting equipment?
fiber laser cutting machine
1. Fine plasma cutting
Precision plasma cutting most suitable 0.45 ~ 50mm thick carbon steel, stainless steel and aluminum as well as within the thickness of 160mm. But it is not belong to laser cutting equipment.
(1) the length of the cutting unit costs in part or 6.35 ~ 50mm thick carbon steel with respect to the other process is the lowest.
(2) ease of use and software equipped with the latest CNC, plasma is very easy to use. Because professional process parameters have been built in the nesting software, so the operator does not experience requirements.
(3) productivity thickness greater than 6.35mm, cutting speed of the laser. When the thickness is less than 50mm, cutting speed in flames. Plasma cutting technology is the fastest of all, efficient.
(4) cutting precision steel cutting element tolerance ± (0.38 ~ 0.5) mm. For less than the thickness (9.5mm) sheet, the slope of the 2o ~ 3o. For thicker than 12.7mm thick plate, the slope within 1o.
(5) edge quality and metallurgical properties of the heat-affected zone is very small, typically <0.25mm. Section good weldability, smooth dross.
(6) Maintenance requirements are relatively simple.
2. Fiber laser cutting
Fiber laser metal cutting machine is the latest laser technology and laser cutting equipment. The use of solid-state laser generator is more efficient than conventional CO2 laser, and the wavelength of the fiber laser is suitable for conducting the valuables of fiber, compared to only use CO2 laser mirror reflection conducted more flexible, easier to maintain. By focusing the laser energy, the molten material being cut, the auxiliary gas blow off the molten metal. A 3kW fiber laser metal cutting equipment is equivalent to 4 ~ 5kW CO2 laser on the cutting ability and speed. Its cutting ability generally can achieve 19mm thick carbon steel.
(1) Unit cost of parts, or the length of the cut when the thickness is less than 6.35mm, most advantage of laser cutting costs. With the increase in thickness, the cutting speed significantly reduced, although the cutting quality and accuracy is very good, but the cost is higher than plasma cutting.
(2) ease of use and the latest plasma system is similar, when equipped with the latest CNC and software, laser cutting machine is also easy to use, since all settings are automatic.
(3) The productivity of the most efficient sheet, when the thickness is increased to 6.35mm, and plasma cutting flat.
(4) The best fiber laser cutting equipment precision cutting element within a tolerance of ± 0.25mm. Better than plasma cutting, water-jet cutting comparable. Slope within 1o.
(5) edge quality and metallurgical properties of the heat-affected zone is slightly smaller than plasma.
(6) maintenance requirements compared to the previous CO2 laser, dramatically reducing the difficulty of maintaining fiber laser.
3. The flame cutting
Flame metal cutting and more for 6.35 ~ 150 mm steel cutting cutting, when more than 50mm thick cutting speed than other processes.
(1) Unit cost of parts, or the length of the cutting gas quite a bit, cutting slow. The thicker steel plate, with respect to the plasma, which cut the cost advantage. Typically the cost per foot than plasma cutting height, more than 50mm thickness, the cost is relatively low.
(2) ease of CNC flame cutting machine tools require the operator a lot of experience in order to achieve the fastest cutting speed and best cutting quality.
(3) Productivity flame cutting due to the long warm-up time, cutting speed is slow, so low productivity.
(4) good precision cutting member operatives in the most suitable speed, altitude, the gas nozzle, the cutting element is about tolerance ± 0.76mm, pitch <1o.
(5) edge quality and metallurgical properties of the heat-affected zone flame cutting large cross-section and has a rough dross.
(6) Maintenance is relatively simple.
4. Waterjet Cutting
Compared to other metal cutting process, water jet two biggest advantage is that there is no heat affected zone and can cut almost any material. Also good water jet metal cutting accuracy. But the biggest disadvantage water jet cutting in its very slow.
(1) Unit cost of parts, or the length of the cut by water jet cutting speed is too slow, so cut the cost per part compared to other process is the highest.
(2) ease of use is similar to the latest plasma system, when equipped with the latest CNC and software, waterjet cutting machines are easy to use, the operator’s experience requirements are very low.
(3) productivity in carbon and stainless steel is very slow, can quickly cut aluminum.
(4) precision waterjet cutting member of accuracy is the best of all the cutting process, the cutting element is about tolerance of ± 0.13mm. Slope within 1o.
(5) edge quality and metallurgical properties has no effect on the metallurgical properties of the material being cut. Smooth section, cut quality and grit and cutting speed.
(6) Maintenance requirements are relatively simple.

Now there is many different metal cutting equipment in the market. Fiber laser cutting machine is one of the most advanced solution. It is becoming more and more popular as its excellent cutting effect and low running cost. Compared with tradition cutting equipment, fiber laser cutter should be the most economic machine.
Fiber laser cutting machine may include 3 parts running cost, electric power, auxiliary gas and quick wear parts.
Electric power cost for fiber laser cutting machine
There is three main part need use electric power, laser source, machine bed and water chillier. Follow date based on 1000w fiber laser source.
We know fiber laser source have very high photoelectric conversion, and it is about 25%. So one set 1000w laser source will cost 4kw power per hour. About machine bed, the main electric power cost parts are servo motor, reducer and control system, and servo motor is main. Now we total use 4 sets servo motor for 1500*3000mm fiber laser cutting machine. Its total power is about 4kw. Water chiller also have high power cost, for 1000w laser source, the suitable chillier will cost about 3kw per hour. In this case, one set 1000w fiber laser cutter’s total power cost is 11kw.
But actually, one machine’s real cost is only about 60%. As it is not possible if all parts keep running with full power. So one 1000w fiber laser machine only cost about 6.6kw/hour. We get this date from thousands of test. Nearly no any machine can cost less then fiber laser.
Auxiliary gas
Fiber laser cutting need use auxiliary gas. Mild steel need use O2 gas, and other metals main use N2 gas. Also we can use compressed gas when cut thin ss and ms less than 2mm. Auxiliary gas cost have relation with metal thickness, so we can’t list it here, and just some recommend for reference.
According to our experience and customers‘ feedback, liquid nitrogen and liquid oxygen is better. First, liquid gas is cheaper. Second, each tank have some rest when using. As its pressure become low so that we can’t use it on running. But when we use liquid gas, it is one big tank, no need change tank always. So all gas will be use.
Quick wear parts
Fiber laser cutting machine quick wear parts main include protective lens, focus lens, nozzle and ceramic rings. Their lifetime is about 500 hours and Ceramic rings lifetime is about 1 year. Protective lens and nozzle is cheap and about 15~30usd/piece. Ceramic ring not more than 100usd/piece. Focus lens is about 150usd/piece.
Except above cost, fiber laser cutting machine near have no any other running cost. Even its price is very high when we buy, but running cost should be the cheapest.
Besides the main machine configurations,you should also focus on the machine body.
Metal sheet fiber laser cutting machine
Sharing the difference between the metal sheet welding lathe bed and the square tube welding lathe bed
The weight of the lathe bed:
square tube welding lathe bed
2.6 MT
metal sheet welding lathe bed
3.3 MT
The heavier lathe bed with a great stability,when cutting, it will not has much shaking,the cutting speed and cutting precision will better.
Cross beam
square tube welding lathe bed
Cast Iron cross beam
metal sheet welding lathe bed
Aluminum cross beam
The aluminum cross beam are integrated,with higher precision when with a higher cutting speed.
The cast iron cross beam link two part into one beam,the precision will be lower.
But the Aluminum is easy to change shape,cause the dentity of the Aluminum is smaller than iron,if you want one Aluminum cross beam,the most important is to notice its thickness,must more than 16mm is okay,or else the cross beam will easy to change the shape,the machine life span time will be reduced.
The guide rail,rack and pinion:
Fixed parts:
The metal sheet welding lathe bed has the block to fix the guide rail to avoid changing the shape.
According to the comparison,the metal sheet laser welding lathe bed with a higher stability,precision,when cutting,the cutting effect will be better than the usual square pipe welding lathe bed.
So when you have a visiting of the factory before your decision,its better to confirm the lathe bed is also great,can meet your cutting precision and stand the higher cutting speed,the heavier material.

What is the difference between laser cutting machine and plasma cutting machine?
Many customers who have just touched the laser cutting machine when consulting laser cutting equipment,
a laser cutting that is part of the thermal processing and plasma cutting machine that is the same.
May be in the early stage of the purchase of equipment, these two devices are not familiar with,
do not know what kind of processing equipment to buy confused.
Therefore, We make these two cutting equipment to do a comparison,
so that we better understand these two devices.
Plasma cutting machine is a thermal cutting equipment, the main working principle is compressed air as the main body to high temperature and high speed plasma arc as heat source,
will melt cut metal partial, and at the same time with high-speed air flow will melt metal blowing, Forming a narrow slit.
Plasma cutting machine can cut stainless steel, iron, aluminum, copper and other metal materials, and cutting speed, slit narrow, incision smooth.
Plasma cutting machines are generally used in the construction, installation and maintenance of mechanical and metal structures.
Laser cutting machine is the use of high-power high-density laser beam scanning material surface,
in a very short period of time can heat to thousands of things or even tens of thousands of degrees Celsius,
the material can melt or vaporize, and then high-pressure gas will melt or blown away other substances are from the slits.
Laser cutting using the invisible beam instead of the traditional mechanical knife,
laser cutting speed, smooth incision, generally do not need post-processing, cutting heat less affected, small deformation plate.
Comparison of the two cutting equipment processing principles, summed up the differences in processing performance in the following areas:
1.Cutting the thickness of the difference, the plasma cutting ability is very strong, able to cut relatively thick metal sheet,
but the accuracy is not high, the speed is not fast,
but also scraping slag, the basic must be secondary processing.
Laser cutting machine only for sheet metal processing, fast, and the accuracy can reach over 0.01mm,
no scraping slag, are basically a molding, no secondary treatment,
but with the laser power is constantly increasing , the current high-power laser Cutting machine can also qualify for the processing of metal plate.
2.The difference in cutting costs, laser cutting equipment, the price is higher than the plasma equipment,
but in the latter part of the processing costs, as well as the cost of recovery than the plasma has an advantage.
Through the above comparison：
I hope everyone on the laser cutting machine and plasma cutting machine have a more profound understanding,
hoping to those who have questions on the choice of equipment friends have some help.
