What is precision laser cutting machine?

Precision laser cutting machine is a laser processing equipment specially designed and manufactured for high-precision and high-quality processing requirements in the field of metal material cutting.

The equipment can cut complex graphics with high efficiency and precision at one time, especially in the dynamic cutting of sharp corners and complex geometric graphics.

The equipment is mainly used for the precision cutting of precision electronic components and high-precision metal small parts.

Current application scenarios include:

  • High quality band saw blade and cutter cutting;
  • Cutting of high-precision components such as cameras and mobile phones;
  • Customized processing of special parts, etc.

Laser precision machining has the following remarkable features:

(1) Wide range:

The object range of laser precision machining is very wide, including almost all metal materials and non-metallic materials;

Suitable for sintering, punching, marking, cutting, welding, surface modification and chemical vapor deposition of materials.

While electrochemical machining can only process conductive materials, photochemical machining is only applicable to corrosive materials, and plasma machining is difficult to process some materials with high melting point.

(2) Precise and meticulous:

The laser beam can be focused to a very small size, so it is particularly suitable for precision machining.

Laser precision machining quality has few influencing factors and high machining accuracy, which is generally superior to other traditional machining methods.

(3) Fast:

From the perspective of machining cycle, the tool electrode of EDM requires high precision, large loss and long machining cycle;

The design of cathode mould for machining cavity and surface of ECM is heavy and the manufacturing cycle is long;

The photochemical processing process is complex;

The laser precision machining is easy to operate and the cutting width is easy to adjust.

It can immediately carry out high-speed engraving and cutting according to the computer output pattern.

The processing speed is fast, and the processing cycle is shorter than other methods.

(4) Safe and reliable:

Laser precision processing is non-contact processing, which will not cause mechanical extrusion or mechanical stress on the material;

Compared with EDM and plasma arc machining, its heat affected zone and deformation are very small, so it can process very small parts.

(5) Low cost:

It is not limited by the processing quantity, and laser processing is cheaper for small batch processing services.

For the processing of large products, the mold manufacturing cost of large products is very high. Laser processing does not need any mold manufacturing, and laser processing completely avoids the edge collapse formed during material punching and shearing, which can greatly reduce the production cost of enterprises and improve the quality of products.

(6) Small cutting seam:

The laser cutting seam is generally 0.1-0.2mm.

(7) Smooth cutting surface:

The cutting surface of laser cutting shall be free of burrs.

(8) Small thermal deformation:

The laser cutting of laser processing is thin, fast and concentrated, so the heat transferred to the cut material is small, and the deformation of the material is also very small.

(9) Material saving:

Laser processing adopts computer programming, which can carry out material nesting for products of different shapes, maximize the utilization rate of materials, and greatly reduce the material cost of enterprises.

(10) It is very suitable for the development of new products:

Once the product drawing is formed, laser processing can be carried out immediately, and you can get the physical object of the new product in the shortest time.

In general, laser precision processing technology has many advantages over traditional processing methods, and its application prospects are very broad.

Working principle of precision laser cutting machine

Precision laser cutting machine uses high-energy pulsed laser to cut objects.

The xenon lamp is pulsed by the laser power supply to form a light wave with a certain frequency and pulse width, which is radiated on the workpiece by the condenser cavity to make local melting and vaporization to achieve cutting.

The equipment is equipped with a high-precision CNC worktable controlled by a working PC. During cutting, high-precision cutting and drilling are carried out through laser frequency, pulse width, worktable speed and moving direction.

Laser cutting processing uses the high density energy of the laser beam to focus through the lens and gather a tiny spot at the focal point.

The laser power density at the focal point is as high as 106~109 W/cm2.

Local high temperature of more than 10000°C will be generated on the material, which will vaporize the workpiece instantaneously, and then the vaporized metal will be blown away with auxiliary cutting gas to cut the workpiece into a small hole.

With the movement of the CNC machine tool, countless small holes will be connected to form the external shape to be cut.

Because the frequency of laser cutting is very high, the connection of each small hole is very smooth, and the finished product is very high.

As the beam moves to the material, the hole continuously forms a narrow slit (such as about 0.1m) to cut the material.

Precision laser cutting machine is mainly used for non-contact cutting and punching of metal plates and pipes, with a minimum cutting seam of 0.1mm, especially suitable for cutting and punching of stainless steel plates, iron plates, silicon chips, ceramic chips and other materials.

Advantages of precision laser cutting machine

All laser cutting processes have their inherent advantages and disadvantages, but it seems that the advantages of fiber laser cutting machine far exceed any other process.

Optical fiber laser has only begun to attract attention in the past few decades or so, but its benefits have been rapidly realized by metal manufacturers across the country.

We found that the fiber laser cutting machine has many advantages, and many application industries have been derived, such as stainless steel, carbon steel, and manganese steel processing can not be separated from the fiber laser cutting machine.

The high-precision fiber laser cutting machine is well distinguished from other laser cutting machines, with small size, small power, small size, high precision and fast speed.

With the continuous updating and development of high-precision fiber laser cutting machine, more advantages will bring more convenience.

1. Small precision optical fiber laser cutting machine can ensure the cutting processing of small size, and is suitable for some small metal materials, such as advertising, kitchen utensils, etc.

Comparatively speaking, the power is also lower than that of ordinary fiber laser cutting machines.

2. The cost of small precision fiber laser cutting machine is relatively low, which is very suitable for small enterprises or enterprises with small processing volume.

The small precision fiber laser cutting machine covers a relatively small area, so it is more convenient for placement and handling.

3. The precision of the small precision fiber laser cutting machine is relatively high, and the focus spot is relatively fine, the cutting accuracy can reach 0.1mm, and the cutting surface is also very smooth.

In addition, its cutting speed is also very fast, more than 100 times that of wire cutting.

4. The cost of small precision fiber laser cutting machine is relatively low.

Its price is only one-third of that of the same-energy fiber laser cutting machine, and two-fifths of that of the numerical control punch with the same effect, and the use cost is low.

In addition, the maintenance cost of small precision fiber laser cutting machine is also relatively low.

It is mainly applicable to the glasses industry, craft gifts, hardware accessories, electronics, electrical appliances and other precision metal products industries.

Complex cutting with good edge quality can be accurately completed on laser cutting equipment.

Precise laser beams can create components with precise tolerances in a fast, clean and efficient manner, with little operator intervention.

Advanced software and narrow cut make parts closely nested, so as to maximize production and reduce material waste.

Parts & functions of precision laser cutting machine

The main structure of the precision fiber laser cutting machine includes:

Fiber laser: it is the core component of the fiber laser cutting machine, and also the “power source” of the fiber laser cutting machine to realize the cutting operation.

Compared with other types of lasers, fiber lasers have the advantages of higher efficiency, longer service life, less maintenance and lower cost.

Cutting head: the cutting head of the laser cutting machine is a laser output device, which is composed of the nozzle, focusing lens and focusing tracking system.

The cutting head of the laser cutting machine will walk according to the set cutting path, but the height of the laser cutting head needs to be adjusted and controlled under different materials, different thicknesses and different cutting methods.

Servo motor: servo motor refers to the engine that controls the operation of mechanical components in the servo system, and is an indirect speed change device for the auxiliary motor.

The servo motor can control the speed and position accuracy very accurately, and can convert the voltage signal into torque and speed to drive the control object.

The high-quality servo motor can effectively guarantee the cutting accuracy, positioning speed and repeated positioning accuracy of the laser cutting machine.

Water chiller: The water chiller is the cooling device of the laser cutting machine. It can cool the laser, spindle and other devices quickly and efficiently.

The current chillers have advanced functions such as input and output control equipment switch, cooling water flow, high and low-temperature alarm, and the performance is more stable.

There are two kinds of gas sources: bottled gas and compressed air.

Body: The bed, beam, workbench and Z-axis system of the laser cutting machine are collectively referred to as the host.

When the laser cutting machine is cutting, first place the workpiece on the bed, and then use the servo motor to drive the beam to control the movement of the Z axis.

The user can adjust the parameters according to his own needs.

Control system: It mainly controls the machine tool to realize the movement of X, Y and Z axes, and also controls the output power of the laser.

Stabilized power supply: connected between laser, CNC machine tool and power supply system.

It mainly plays the role of preventing external power grid interference.

It is suitable for marking, cutting and punching of various metal sheets and micro-precision metals, mainly used in LED, precision machinery, semiconductor control devices and 3C parts industries.

How to choose the right precision laser cutting machine?

Where to buy a professional precision laser cutting machine?

I’m afraid that is the concern of many of our customers engaged in precision sheet metal and sheet metal processing.

There are so many manufacturers producing precision laser cutting machines in the market. Which manufacturers can produce professional precision laser cutting machines? What should we pay attention to when we buy?

Related reading: Top 20 Laser Cutting Machine Manufacturers

First, look for professional precision laser cutting machine manufacturers

When purchasing precision laser cutting machines, we should pay attention to the fact that many precision laser cutting machine manufacturers cannot produce professional precision laser cutting machines.

We should be alert to these manufacturers using conventional precision laser cutting machines to fool us.

How to distinguish whether precision laser cutting machine manufacturers can produce professional precision laser cutting machines, the most direct way is to take samples to the manufacturer for sample testing.

Second, looking for manufacturers should start from product quality and function

No matter which manufacturers we can find, it is most important to pay attention to the precision laser cutting machine itself.

We can test the quality of the precision laser cutting machine from several aspects:

  • The thickness of the machine tool can reflect the bearing capacity of the precision laser cutting machine;
  • The internal structure of the precision laser cutting machine can reflect the use performance and function as well as the stability of the frame;
  • The spraying process of the surface can reflect the manufacturing process;
  • The operating system can reflect the convenience of dense shelves.
  • From these aspects, we can know whether the products produced by the precision laser cutting machine manufacturers are suitable for our use.

Third, the conventional precision laser cutting machine can not meet the needs and may have to be customized!

Sometimes, if the professional precision laser cutting machines produced by manufacturers can not meet our needs, we should consider customization.

Not all precision laser cutting machines are the same, and the products required are naturally different.

This is why many manufacturers provide customized services for precision laser cutting machines. If we want manufacturers to provide customized precision laser cutting machines, we must communicate the details with the manufacturers. 

Some structural requirements of precision laser cutting machine should be clearly expressed to avoid invalid communication.
