procedure laser cutting
Laser cutting of metal - the most progressive and promising technique, which generate high-quality elements, although it is a relatively young technology.The procedure is carried out with the help of technically focused high-power lasers, which are characterized by a high concentration of the beam and can cut any materials - from wood to met
On the metal surface with the formed oxides, and increasing the energy absorption causing the temperature to the melting point.At the point of contact laser beam creates heat, causing the metal melts and abroad contact area only heats up.Simultaneously a reactive gas is fed, usually oxygen, which blows combustion gases and causing an increase in cutting speed.The video laser cutting can be seen that by blowing the molten metal and oxides, the oxygen heats the following layers.
This process occurs until the metal is not be cut to the full depth.A stream of oxygen is able to actively cool the metal near the cutting lines.A small area of thermal effect provides the possibility of creating parallel edges at small distances - up to about 0.2 millimeters.Often, in order to achieve the necessary precision cutting operation, the workflow is controlled by computer, through which will sprogramirovat any product.
mainly for laser cutting of sheet metal using machines based on gas and solid state lasers.Laser cut metal goes perfectly flat without deformations which are present in the mechanical aspect.Besides laser cutting technology allows for significant accuracy of, minimum waste and fast execution.
advantages of laser cutting
Due to its advantages of laser cutting technique - the most demanded in the market.It is this procedure greatly facilitated work carbide materials, which are very difficult to process and often lead to a deterioration in quality after processing.For laser cutting most suitable non-ferrous metals, steel and aluminum alloys.
laser cutting simplifies the handling of the thickened sheets of thick materials and alloys of complex parts of parts, as well as cut holes in superhard materials of small diameter.The geometry of the product is limited to only a fantasy design.On the other hand due to the nature of contactless technology for laser cutting of metal can be cut thin and fragile materials.
To automate the operation of the system it is only necessary to prepare for a computer file.Since in this case there is no mechanical stress on the material, the metal product does not require further machining.
Another advantage of laser cutting of metal - thanks to program the cutting of sheet metal it is possible to reduce the cost to produce small batch production, because there is no need for the manufacture of molds.Simple management tools allow workers to cut contours in bulk and flat parts.If you compare the laser cutting of metal with their hands with plasma, then today preferred the first option, because the laser cutting of metal is much cheaper.
Using laser cutting
procedure for laser cutting of metal can be used not only for direct cutting and engraving for various products.Laser cutting is also designed for short-run production.For this purpose customary to use equipment which is characterized by a low laser power and small size.
If there is a problem to release a series of parts, is to work with more powerful unit - a laser system that includes a laser coordinate table and a computer with special software to maintain vector graphics.
at similar equipment can be done with minimal errors (0.001 millimeters) rather complex processes, such as laser cutting volume and cutting parts of a complex circuit.
Using similar technology materials cut out sheets - structural and stainless steel, aluminum, wood and even plastic.Works are carried out in a short period of time with affordable price for laser cutting of metal and impeccable quality.Laser cutting allows us to produce parts that have complex contours, producing products such as a variety of logos, signs, souvenirs and decorations.
Laser equipment - pretty standard.The machine consists of a work table and the laser cutting head that is moving in its plane.The movement of the laser head is provided with precision drives along the perpendicular guide to provide a clear outline details.
principle of operation of the machine
The device is equipped with a laser cutting of metal cutting optics for bezoksidnoy cutting.The optical focusing system helps to maintain a predetermined position of the focus, which helps to get the result of the processing circuit more precise and clear.Controls the movement of the cutting head by means of a special computer program cutting.
With the program set the sequence of commission of current and future operations.The program adjusts the strength of radiation regardless of the depth of cut and, therefore, allows to make the most complex decorative elements and parts for various equipment.To automatically cutting sheet metal, you must be a drawing file that is transferred to the computer of the cutting unit.
For laser equipment requires minor costs of electricity, and the high cutting speed and a lack of consumables create the conditions for an efficient workflow.The performance of the machine can be increased by increasing the power of the radiation, which is regulated in the process.The cost of laser cutting of metal with a special machine is dependent on the sheet thickness and the length of the cutting line.
used technological principles, which are based on the device of gas and fiber lasers, which are capable of operating in a continuous and pulsed mode.Work carried out on the machine by means of burning through the sheet material by the laser beam.
Due to the absence of direct contact of the product and the cutting head equipment to safely handle fragile items, carbide material is easy to cut sheet steel at high speed, it is advantageous in output is produced in small batches.Laser cutting of metal colored or black no physical deformation and micro-cracks on the surface of the finished products.
Prices for laser cutting machine of the new generation are very different, depending on the brand of the manufacturer and installed options.For the installation of the complex there is no need to arrange special training for the foundation, you can place the machine in any location that provides technological access.
laser equipment for laser cutting machines are classified according to the operating parameters - the intensity of the radiation, the type of workpiece material, pressure and composition of the cutting gas jet.Equipment for laser cutting of metal is divided into the following types of cutting: oxygen, oxygen-enabled laser vaporization in an inert gas, termoskalyvayuschee.Produced specialized machines for laser cutting of pipes that protrude suitable for all profiles, the processing can be performed directly over the entire length of the workpiece.
Laser machines proved themselves in cutting steel sheets with thickness 0,2-25 mm, stainless steel having a thickness of 0,2-30 mm, aluminum alloy thickness of 0.2-20 mm, brass with a thickness of 0.2-12millimeters thick copper 0.2-15 millimeters.For the treatment of different materials used different types of technologies and lasers, photo laser cutting of metal can be seen on the network.
machine has found wide application for the production of metal parts, decorative elements of the interior, when working with plastic and soft metals.The cost of laser cutting machine with the correct operation justifies itself and quickly pays for itself.Products that are manufactured using laser machines equipped with different economic feasibility and high profitability.
Thus, the laser cutting is advanced technology in the world of work with metals that every day is gaining momentum.This technique allows to facilitate workflow.Besides the metal treated has a quality cut and contains no microcracks and deformation.
