The kinds of laser cutting machine and structure is introduced

1, from the point of view of cutting head, the workbench mutual movement, CNC laser cutting machine can be divided into fixed beams, flight path and three types of fixed and mobile hybrid optical path. In addition, there is a hinge arm is fixed optical path flight beam transmission form, known as the fixed flying light path, referred to as a fixed optical path.



in the cutting process, as long as the cutting head along the X, Y direction move, workbench fixed position. The cutting machine, large range of processing board, the quality is great; Equipment of the air volume is small, do not need to clamp workpiece processing, loading and unloading lunch; Machine acceleration performance is good, high positioning accuracy. As a result, it was the height of the love, is known as the mainstream of the international market.



2, at present, the common laser cutting machine, the products are: gantry moving type flying light path structure, beam, beam is moved down move or move, fixed cantilever beam gantry half a flight path, cross table move type fixed optical path, gantry and cantilever constant light path, the robot structure mode and several typical structure such as air. Bearing mixed light path area is large, laser sensitive disposal system, etc.



3, in terms of the structure of the machine, and lathe bed and other large parts of data for the casting structure, welding structure, and marble, the beam is made up of aluminium alloy casting or welding parts and its profile. Other components include engineering plastics, glass fiber and the application of stainless steel.



4, when choosing laser, should be based on the machining performance, materials, shape, size and other factors, choose a different laser. Be able to select the laser are: fast CO_2 axial flow laser, radio frequency (rf) board debugging laser, laser, solid laser and fiber laser, etc.



5, from the perspective of the driving mode of equipment, X, Y axis by the corresponding single servo motor driven gear reducer, gear rack; X axis by corresponding gear reducer, gear rack on both sides of the servo motor drive; Double eliminate reverse gear clearance; Servo motor directly by high precision ball screw drive, the disk A big inertia motor used in straight tooth, wheel rack drive; A linear motor direct use, direct drive structure.



6, in the structure of the CNC laser cutting machine, guide usually give priority to with high precision linear guide, and is equipped with automatic smooth installation. With unilateral linear guide of roller structure is a kind of typical structure than good performance price, economic, applicable, prepared lunch. Another structure is the direct use of drive, guide rail group collaboration as one of the structure of the drive unit, device has the advantages of simple analogy, debugging match bento, easy to guarantee accuracy, but capital is higher.
