Components of Intelligent Laser Cutting Head
Laser delivery fibre
Right at the top (or side) of the head is the laser delivery fibre. This brings the beam from the laser resonator to head, via a length of glass fibre. At this point the beam is tiny. It's been compressed inside the resonator ready to be sent to the head through the fibre.
Collimation lens
The collimation lens expends the compressed beam from the laser delivery fibre, up to a usable size. When the beam leaves this optic its ready for delivery to the focusing lens. This optic is not user serviceable.
Focus or cutting lens
The focus or cutting lens takes the expanded beam and focuses it to a very small spot. This is generally focused on or into the work piece. The energy density of this spot is what allows the processing of materials with the laser. This optic is not user serviceable.
Focus adjustment drive
Most modern heads have a lens positioning system within them. These are generally servo controlled and are very accurate. These systems allow the focal position of the cutting lens to be placed very accurately on to the work piece, via the control system, and tech tables of the machine. This system is very fast in operation and makes switching cutting styles simple, and seamless for the operator.
Protective window or cover slide
It's very important to keep the optics mounted in the head completely clean and free of contamination. To this end, most modern heads contain protective window or cover slide to keep the cutting process isolated from the main optical components of the head. The protective window is relatively inexpensive when compared to the cutting or collimating lens and is consumable. The protective window is operator serviceable.
Assist gas cavity
The cutting process requires an assist gas. This gas is introduced through the assist gas inlet into the assist gas cavity, directly below the protective window. The gases in this cavity can be at extremely high pressure and are there to assist cutting.
Copper nozzle
The main function of the nozzle is to deliver a jet of gas to the cutting process in a controlled and stable manner. This relatively low-cost component is key to good processing. It must be kept in good condition and should be inspected frequently.
How to Choose a Intelligent Laser Cutting Head
Type and structure of cutting head
The types and structures of intelligent laser cutting heads are varied and suitable for different materials and cutting requirements. When choosing a laser cutting machine, you must understand the type and structure of the cutting head used and choose the appropriate cutting head according to the processing requirements. For example, cutting thick metal materials requires a cutting head with greater power and larger nozzle diameter, while cutting thin metal or non-metallic materials requires a high-precision cutting head.
Optical parameters
Optical parameters are key factors affecting the performance of intelligent laser cutting heads. These parameters include collimation focal length, focusing focal length, spot size, effective working focal length, adjustable focusing range, etc. They are closely related to the cutting process of the laser cutting head. Whether different cutting processes can be effectively implemented and whether the intelligent laser cutting head can meet the requirements of a certain process depends on the appropriate optical parameters. When choosing an intelligent laser cutting head, various optical parameters should be given priority.
Nozzle design
The design of the cutting head nozzle is one of the key factors affecting cutting efficiency. The design of the nozzle needs to consider factors such as the focusing method of the laser beam, the nozzle material, and the nozzle diameter. A well-designed laser nozzle can effectively control the shape and size of the laser beam and improve cutting accuracy and speed. Therefore, when choosing a laser cutting machine, you should pay attention to choosing a cutting head with a reasonable nozzle design.
Compatibility
The intelligent laser cutting head needs to be used with a variety of equipment such as laser cutting machines, chillers, lasers, etc. The compatibility of the intelligent laser cutting head is determined by the strength of the manufacturer. The intelligent laser cutting head with good compatibility has strong synergy ability and will not affect the performance of other equipment, effectively improving work efficiency.
Power and heat dissipation
When choosing an intelligent laser cutting head, power and heat dissipation are crucial factors. The power of the intelligent laser cutting head determines its cutting ability, that is, the thickness and speed of the material it can cut. The more powerful the cutting head is, the easier it is to penetrate thicker materials, but it also requires a more effective heat dissipation system to avoid overheating and damage to the equipment. Overheating can cause the performance of the intelligent laser cutting head to deteriorate or even damage, affecting the cutting quality and stability. Therefore, it is crucial to choose an intelligent laser cutting head with a good heat dissipation system.
Cutting accuracy
Cutting accuracy is the basis for selecting an intelligent laser cutting head. This accuracy refers to the contour accuracy of the workpiece during cutting, not the static accuracy marked on the sample. The difference between the quality of an intelligent laser cutting head lies in whether the accuracy changes when the part is cut at high speed, and whether the consistency of different positions of the workpiece changes.
Cutting efficiency
Cutting efficiency is a key indicator of the performance of intelligent laser cutting heads. Cutting efficiency refers to the time required to cut a workpiece, rather than simply looking at the cutting speed. Cutting efficiency is affected by factors such as power and speed matching, cutting quality and stability, automation and intelligence, cutting head design and material. Comprehensive consideration of these factors can improve cutting efficiency, improve production efficiency, and reduce costs.
Durability and maintenance cost
The durability and maintenance cost of the cutting head are also factors to consider when choosing a laser cutting machine. Generally, a good quality cutting head has a longer service life and lower maintenance cost. When choosing a laser cutting machine, you need to understand the durability and maintenance cost of the cutting head, and consider comprehensively to choose a cost-effective cutting head.
Beam generation
The laser beam is a column of very high-intensity light, of a single wavelength, or colour. In the case of a typical co2laser, that wavelength is in the infrared part of the light spectrum, so it is invisible to the human eye. The beam is only about 3/4 of an inch in diameter as it travels from the laser resonator, which creates the beam, through the machine's beam path. It may be bounced in different directions by several mirrors, or "beam benders", before it is finally focused onto the plate. The focused laser beam goes through the bore of a nozzle right before it hits the plate. Also flowing through that nozzle bore is a compressed gas, such as oxygen or nitrogen.
Beam focusing
Focusing the laser beam can be done by a special lens, or by a curved mirror, and this takes place in the laser cutting head. The beam has to be precisely focused so that the shape of the focus spot and the density of the energy in that spot is perfectly round and consistent, and centred in the nozzle. By focusing the large beam down to a single pinpoint, the heat density at that spot is extreme. Think about using a magnifying glass to focus the sun's rays onto a leaf, and how that can start a fire. Now think about focusing 6 kwatts of energy into a single spot, and you can imagine how hot that spot will get.
Localised heating
The high power density results in rapid heating, melting and partial or complete vaporising of the material. When cutting mild steel, the heat of the laser beam is enough to start a typical "oxy-fuel" burning process, and the laser cutting gas will be pure oxygen, just like an oxy-fuel torch. When cutting stainless steel or aluminium, the laser beam simply melts the material, and high-pressure nitrogen is used to blow the molten metal out of the kerf.
Beam movement
On a cnc laser cutter, the laser cutting head is moved over the metal plate in the shape of the desired part, thus cutting the part out of the plate. A capacitive height control system maintains an exactly accurate distance between the end of the nozzle and the plate that is being cut. This distance is important because it determines where the focal point is relative to the surface of the plate. Cut quality can be affected by raising or lowering the focal point from just above the surface of the plate, at the surface or just below the surface.
Safety Precautions When Using the Intelligent Laser Cutting Head
