The use of laser cutting machine in industrial products has developed rapidly in recent years, showing high processing ability and economy. Its near-infrared wavelength (1080nm) is also more conducive to the absorption of metal materials. Low operating cost; Optical fiber transmission and optical fiber laser cutting equipment have the following characteristics: low maintenance, compared with the gas CO2 laser, it does not need reflective lenses, the laser does not consume working gas, and it does not need to adjust the external optical path; Low power consumption, low energy consumption, energy conservation and environmental protection.

1. Why does the laser cutting machine adopt gantry structure

CNC laser cutting equipment generally adopts gantry type, cantilever type, middle inverted beam, etc. It is also the structural type adopted by many famous brand laser cutting machine manufacturers. The gantry structure has also become the mainstream model in the world with its special structural advantages. However, with the development of high-speed and high volatility requirements and control technology, the use of laser processing has progressed. Compared with the traditional CO2 laser cutting machine, the changes lie in the external optical path, cutting head, auxiliary gas, etc,

2. What are the characteristics of laser cutting machine process

The use of optical fiber laser cutting equipment in metal plate cutting. The fluctuation of the optical path is firm to ensure the consistency of the full width cutting of the machine tool. Generally, a focusing lens with a focal length of 125mm or 200mm can be configured. The focal depth is short, and the machine tool does not need the protective gas of the external optical path. A protective lens must be installed between the focusing lens and the nozzle to prevent the focusing lens from being polluted; The optical fiber laser has a good focusing function. The cutting seam is narrower (up to 0.1mm). It is suitable for fast cutting of medium and thin plates. The speed is higher. The laser can be transmitted to the cutting head indirectly through the optical fiber. No air compressor or other disposal systems will be equipped; The laser is collimated and focused after it reaches the cutting head.

3. Why is the laser cutting machine driven by helical gear and rack

Several common linear shaft transmission modes of CNC machine tools include ball screw, gear rack and linear motor. High speed and large stroke can be realized; Linear motor is mostly used for CNC machine tools with high speed, high acceleration and special structure, and ball screw is commonly used for CNC machine tools with medium and low speed and small stroke; The gear rack is widely used. In addition, the gear rack is divided into straight teeth and helical teeth. Helical gear is relative to straight gear, and the transmission between gear and rack will be more stable and the meshing area will be larger. Second, the gantry is fixed while the workbench moves,

4. What are the characteristics of laser cutting machine bilateral drive

The gantry type laser cutting machine has two motion modes. One is that the gantry moves while the workbench is fixed during processing. The first method is commonly used. As for the large format, high-speed and high-performance laser cutting machine, the worktable is not suitable for high-speed and thick plate cutting because of the worktable moving with the workpiece. Bilateral driving ensures the force balance of the beam and the synchronization of the beam operation. The laser cutting machine of some manufacturers adopts gantry unilateral drive, and then transmits the driving force to the other end through a long shaft to achieve double gear rack drive and single servo motor drive. The servo motor is installed at one end of the gantry beam. The synchronization accuracy is affected. Unilateral driving makes the force on both ends of the beam asymmetric, reducing the dynamic function of the machine tool.
