The equipment of compositive Laser Cutting of Laser Cutting equipment differs by laser job material, can divide for equipment of solid Laser Cutting equipment of gentle style Laser Cutting; By laser working way differs, cent is equipment of successive Laser Cutting and equipment of pulse Laser Cutting. Laser Cutting uses CO2Laser Cutting device mostly, main by laser, guide source of system of optical system, numerical control campaign, cutting torch, work station, gas, fountainhead and smoking system are comprised. The basic form prejudice of typical CO2Laser Cutting equipment pursues 1. Laser Cutting equipment the action of each structure is as follows. The high-pressured power source that oscillation of laser of supply of ① laser power source uses. The main facility ③ of laser of generation of ② laser oscillator refracts illuminator to be used at the way that laser oriented place needs. To make access of beam of light does not malfunction, all illuminator want to try to protect with protective cover. ④ cutting torch basically includes the part such as lens of gun put oneself in another's position, focusing and auxiliary gas nozzle. Platform of ⑤ cut work is used at putting by cut workpiece, can have shift accurately by control, normally by drive of electric machinery of wait for one's chance. Actuating device of ⑥ cutting torch is used at moving according to direction of axis of X of edge of program drive cutting torch and Z axis, wait for transmission by servo electromotor and filar lever composition. Device of ⑦ numerical control undertakes controlling to the motion of cut platform and cutting torch, also control the output power of laser at the same time. ⑧ handles dish of job process that is used at controlling whole cut apparatus. ⑨ gas cylinder includes gas cylinder of laser job medium and auxiliary gas cylinder, the working gas that is used at compensatory laser oscillation and supply cut use auxiliary gas. Device of loop of ⑩ cooling water is used at cooling laser oscillator. Laser is the device that uses electric energy to be changed into light energy, like the changeover of CO2 gas laser efficiency is commonly 20% , the rest 80% energy are quantity of heat with respect to commutation. Cooling water takes away redundant quantity of heat in order to hold the regular job of the oscillator. ⑾ air desiccator uses the dry air with Yu Xiangji smooth oscillator and clean supply of access of beam of light, in order to hold the regular job of access and illuminator. Laser Cutting basically has laser of solid of aluminous garnet of He Yi of CO2 gas laser with laser with laser cut (call YAG laser normally) . The main character of CO2 laser and YAG laser and main use see a table 1, cut processability can see a table quite 2. The main character that expresses 1 CO2 laser and YAG laser and wavelengh of main use laser / ① of efficiency of power of output of µm oscillation form / laser of % utility CO2 1.

6 pulse / successive 20kW20 stiletto, cut, solder, efficiency of heat treatment ① shows the energy of medium of devoted laser job and laser output energy than. The cut processability that expresses 2 CO2 laser and YAG laser can compare role of diverge of beam of light of function of focusing of laser of YAG of project CO2 laser small, easy obtain base model, focusing gloriole spot is small, part of diverge of power density tall beam of light is small, obtain odd mode not easily (only laser of YAG of ultrasonic Q switch can produce odd pattern) , focusing gloriole spot is bigger, power density low metal is right the absorptivity of laser (normal temperature) character of small tall cut is good (cut ply is big, cut rate is rapid) poorer (cut capacity is small) structural character structure is complex, volume is minor, ask to the precision of smooth road high structure is compact, volume is minor, sex of simple care and maintenance needs smooth road and optical part favorable treatment is flexible poor (of beam of light communicate support illuminator, convey hard different working station) good (can use fiber-optic dimension to transmit light beam, a laser can be used at many labour, also can much stage is the same as model laser use consecutively) laser of gas of CO2 of laser of ⑴ CO2 gas is to use close the CO2 gas inside container (the mixture body that is N2 and CO2, He actually) endure the generation after stimulating oscillation as working material. The basic structure of CO2 gas laser sees a picture 2. Gas through bringing to bear on high-pressured report forms glow discharge state, have the aid of is set in container the illuminator of two end makes its suffer drive to produce laser ceaselessly in the area between illuminator. CO2 gas laser basically has gas to close axis of container type, low speed sheds axis of type, high speed to sort type and crosscurrent type (discharge namely direction, smooth axis direction and aeriform flow direction become orthogonality) wait for a type. Laser Cutting uses an axis to shed laser of type CO2 gas commonly. The major attribute of laser of a few kinds of CO2 sees a table 3. The structural principle of laser of solid of YAG of laser of ⑵ TAG solid sees a picture 3. It is optics of have the aid of the energy that pump action changes electric energy conveys in working medium, make in laser room of a pump is formed all round club and electric arc lamp. Pass laser bar at the same time the viewfinder of two end, make light aims working medium, undertake drive magnify in order to produce light to its, obtain laser thereby. Cut sees a table with the sort of YAG laser and main use 4. The sort that expresses 4 cut to use YAG laser and main use project are successive drive of oscillation of switch of Q of general and successive oscillation uses laser pulse laser lamp of lamp electric arc, flashlight Q switch, ultrasonic Q switch, pulse width, 50 ～ 500ms0.

1 ～ 20ms repeats frequency / KHz, ＜ 50 (1 ～ 500) frequency of × 10-6 peak value / KW, 2501 ～ of 10 ～ power of 20 average output / W1 ～ 18001001000 pulse energy / MJ, 150000 main use use 30100 ～ of 1 ～ at thin plate of carbon steel, stainless steel (. Basically wait for composition by lens of cutting torch body, focusing, illuminator and auxiliary gas nozzle. When Laser Cutting, cutting torch must satisfy following requirement: ① cutting torch can eject gives enough breath; The eject direction of the gas inside ② cutting torch must be mixed the smooth axis of illuminator is coaxial; The focal length of ③ cutting torch can go to the lavatory adjust; When ④ cut, those who assure metallic steam and cut metal splatter won't injure illuminator; The shift of cutting torch is to pass system of numerical control campaign to undertake modulatory, the opposite shift between cutting torch and workpiece has 3 kinds of cases: ① cutting torch is not moved, workpiece moves through workbench, basically use at the workpiece with lesser dimension; ② workpiece is not moved, cutting torch is mobile; ③ cutting torch and workbench move at the same time.
