What is precision laser cutting machine?
Precision laser cutting machine is laser processing equipment specially designed and manufactured for high-precision and high-quality processing requirements in the area of metal materials cutting.
The equipment can cut complex graphics with high efficiency and precision at the same time, especially in dynamic cutting of sharp corners and complex geometric graphics.
The equipment is mainly used for precision cutting of precision electronic components and high-precision small metal parts.
Current application scenarios include:
- High quality band saw blade and cutter cutting;
- Cutting high-precision components such as cameras and cell phones;
- Customized processing of special parts, etc.
Laser precision machining has the following notable features:
(1) Wide range:
The range of laser precision machining objects is very wide, including almost all metallic and non-metallic materials;
Suitable for sintering, punching, marking, cutting, welding, surface modification and chemical vapor deposition of materials.
Although 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 points.
(2) Precise and meticulous:
The laser beam can be focused to a very small size, so it is particularly suitable for precision machining.
The quality of laser precision machining has few influencing factors and high machining precision, which is generally superior to other traditional machining methods.
(3) Fast:
From the perspective of the machining cycle, the EDM tool electrode requires high precision, large losses and long machining cycle;
The cathode mold design for machining the ECM cavity and surface is heavy and the manufacturing cycle is long;
The photochemical processing process is complex;
Laser precision machining is easy to operate and the cutting width is easy to adjust.
It can immediately perform high-speed engraving and cutting according to the computer's output standard.
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 processing quantity, and laser processing is cheaper for small batch processing services.
For the processing of large products, the manufacturing cost of large product molds is very high. Laser processing does not require mold manufacturing, and laser processing completely prevents the edge collapse formed during punching and shearing of the material, which can significantly 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 must be free of burrs.
(8) Small thermal deformation:
The laser cutting of laser processing is fine, 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 savings:
Laser processing adopts computer programming, which can realize material grouping for products of different shapes, maximize the material utilization rate, and significantly reduce the material cost of enterprises.
(10) It is very suitable for new product development:
Once the product design is formed, laser processing can be carried out immediately, and you can obtain the physical object of the new product in the shortest possible time.
In general, laser precision processing technology has many advantages over traditional processing methods, and its application prospects are very broad.

Precision laser cutting machine working principle
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 onto the workpiece through 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 functional PC. During cutting, high-precision cutting and drilling are realized through laser frequency, pulse width, worktable speed and movement direction.
Laser cutting processing uses the high-density energy of the laser beam to focus through the lens and gather a small spot at the focal point.
The laser power density at the focal point is as high as 10 6 ~10 9 C/cm 2 .
Local high temperature of more than 10,000°C will be generated in the material, which will vaporize the workpiece instantly, and then the vaporized metal will be blown 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 outer shape to be cut.
Because the laser cutting frequency is very high, the connection of each small hole is very smooth and the final product is very high.
As the beam moves towards the material, the hole continuously forms a narrow slit (like about 0.1 m) to cut the material.
Precision laser cutting machine is mainly used for non-contact cutting and punching of metal plates and tubes, 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.

Precision laser cutting machine maintenance
Routine maintenance and precautions include:
The machine must be placed in a well-ventilated, clean and well-lit place.
To ensure good ventilation, the distance between the machine and the wall and other obstacles must be at least 1 meter.
After positioning the machine, it is necessary to adjust the shockproof feet according to the ground conditions, so that the equipment table can contact the ground smoothly and be horizontal.
The working conditions of the machine are as follows:
Environmental conditions: working temperature: 5 ~ 35 ℃, relative humidity: 70%, power supply conditions: single-phase two-wire, 220VAC, 4KVA.
The equipment must be installed with grounding resistance (4 ohms grounding resistance to ensure the safe use of the equipment).
The processing site must be equipped with smoking equipment and ventilation ducts to remove smoke and exhaust gases generated during the work process.
Precautions for machine maintenance:
1. When the machine is working, the circuit is in a high voltage state. Non-professional personnel should not check and repair when starting the machine to avoid electric shock.
2. In case of machine failure (such as water leakage, power supply cut off, fuse burnout, laser abnormal, etc.), immediately connect the emergency stop button and turn off the power supply.
3. Regularly check the operating condition of the laser water chiller.
In case of small water flow, water leakage and the temperature cannot be reduced, stop using the laser and repair it before using it.
4. If the equipment is not used for a long period, the internal cooling water must be drained.
In winter, the working environment temperature should not be lower than 10℃, otherwise it is very easy to cause laser failure.
When the working ambient temperature is lower than 0℃, the internal circulating water will be drained in time.
Otherwise, it is easy to cause the water circuit to freeze and break the water tube and internal water circuit of the laser.
5. Maintenance of the optical path system Due to the long-term use of the equipment, the use environment is relatively poor.
Dust in the air may be adsorbed on the protective lens, which may reduce the laser power or cause the optical lens to absorb heat, resulting in burns or cracks.
Dust must be cleaned regularly, otherwise the laser will overheat or the lens will burn.
