Q & A of Heli Fiber Laser Cutting Machine

Release time: 2014.09.19 News source: Laser cutting machine, laser engraving machine, laser marking machine, laser equipment brand manufacturer-Dongguan Heli Laser Equipment Co., Ltd. Browse times:
What are the characteristics of fiber laser cutting machine ?
The application of fiber laser cutting machine in industrial products has developed rapidly in recent years. Its near-infrared wavelength (1080nm) is more conducive to the absorption of metal materials, especially in the field of high-power welding and cutting, showing good processing capabilities and Economical. Compared with gas CO2 laser, fiber laser cutting machine has the following characteristics: low maintenance, low energy consumption, low operating cost; fiber transmission, no reflective lens, no need to adjust the external light path; low power consumption, energy saving and environmental protection, laser does not consume work gas. At the same time, the near-infrared wavelength laser is more likely to cause harm to the human body, especially the damage to the eyes, which requires the device to have better protection functions such as sealing.
2.What are the characteristics of the fiber cutting process?
Compared with the traditional CO2 laser cutting, the application of the fiber laser cutting machine in the cutting of metal plates lies in the external optical path, cutting head, auxiliary gas, etc. The laser is directly transmitted to the cutting head through the optical fiber. The optical path is stable and reliable, ensuring the uniform cutting of the machine tool. Focusing can usually be configured with a focal length of 125mm or 200mm. A protective lens is installed between the focusing lens and the nozzle to prevent the focusing lens from being contaminated; the fiber laser has good focusing performance, short focal depth, and narrower slit width (Up to 0.1mm), higher speed, suitable for fast cutting of medium and thin plates.
3.Why use a gantry structure?
NC laser cutting machines often use structural types such as gantry type, cantilever type, middle inverted beam and so on. With the development requirements of high-speed, high-precision, high-stability laser processing applications, and the development and improvement of control technology, the gantry structure has become the mainstream model in the world with its unique structural advantages, and is also a well-known brand laser cutting The type of structure adopted by the machine .
4.What are the characteristics of bilateral drive?
The laser cutting machine of the gantry structure has two movement forms, one is that the gantry is moved and the table is fixed during processing, and the other is that the gantry is fixed and the table is moved. For large-format, high-speed, high-performance laser cutting machines , the first form is often used because the worktable with the workpiece moved is not suitable for high-speed and thick plate cutting. Our company's DF series CNC fiber laser cutting machine is the first type, and it is bilaterally driven and driven, that is, racks and servo motors are symmetrically installed on both sides of the gantry beam to achieve dual gear rack drive and dual servo motor drive. . The bilateral drive ensures that the beams are balanced and the beams run synchronously. However, some other manufacturers' laser cutting machines use gantry unilateral driving. The servo motor is installed at one end of the gantry beam, and then the driving force is transmitted to the other end through a long shaft to achieve dual gear rack transmission and single servo motor driving. Unilateral driving makes the two ends of the beam unsymmetrical, which affects the synchronization accuracy and reduces the dynamic performance of the machine.
5.Why helical gear rack drive?
Several linear axis transmission methods commonly used in CNC machine tools include ball screws, rack and pinion, and linear motors. Ball screw drive is commonly used in CNC machines with low and medium speeds and small strokes; rack and pinion drives are widely used to achieve high speeds and large strokes; linear motors are mostly used in high speed, high acceleration, and CNC machine tools with special structures. In addition, the rack and pinion are divided into two types: straight teeth and helical teeth. Compared with straight teeth, helical teeth have a larger meshing area, and the transmission between gears and racks will be smoother.
