The driving technical indicators of the optical fiber laser cutting machine are:
Positioning accuracy: As a special processing machine tool, the optical fiber laser cutting machine is similar to the traditional cold processing machine tool. The overall structure of the transmission pair is basically the same, but in general, laser cutting is not used for precision processing. Therefore, compared with precision processing equipment, its processing accuracy is slightly reduced. The laser cutting machine will focus the laser emitted from the laser into a high power density laser beam through the optical path system. The laser beam shines on the surface of the workpiece to make the workpiece reach the melting point or boiling point, while the high-pressure gas coaxial with the beam will blow away the molten or vaporized metal. Optical fiber laser cutting machine is a laser cutting machine that uses the optical fiber laser generator as the light source.
Fiber laser is a new type of fiber laser developed internationally that outputs high energy density laser beam and gathers on the surface of the workpiece to melt and vaporize the area on the workpiece illuminated by the ultra-fine focus spot instantly. Automatic cutting is realized by moving the spot irradiation position through the numerical control mechanical system. The positioning accuracy of the machine tool can also reflect the products of various manufacturers from the side, providing an accurate basis for the design of equipment and the selection of transmission components.

Automatic cutting is realized by moving the spot irradiation position through the numerical control mechanical system. This will not have a significant impact on the participation in the sheet metal processing industry, but the positioning accuracy is very important for slits with accurate cutting tools exceeding 10 microns. Transmission stiffness, in the high-speed transmission process of optical fiber laser cutting machine, the internal stress of the transmission chain will also fluctuate violently. If the transmission stiffness is not large enough, it is easy to cause the distortion of the final output trajectory and the corresponding stagnation. The dynamic motion accuracy is far from the low speed or static measurement value, which affects the dimensional accuracy and roughness of the workpiece.
The repositioning accuracy of the optical fiber laser cutting machine depends on the reverse clearance of the transmission chain to a large extent. As with the traditional cold working, the reverse clearance of the optical fiber laser cutting machine also has a certain impact on the roughness of the section. As the most obvious technical parameter of visual effect, positioning speed is the key indicator concerned by manufacturers, which is often used as the main basis for classifying mechanical properties and grades. High positioning speed plays an obvious role in improving the processing efficiency of thin plates. However, for medium and heavy plates, due to the limitation of cutting speed, it does not play a significant role in shortening the overall processing time. Due to the high flexibility of laser processing, high-speed cutting of complex parts has become the main means for manufacturers to show their mechanical properties. High speed cutting requires high motor output torque, high transmission chain efficiency and fast response speed to ensure accurate trajectory and meet the requirements of blanking.
Therefore, the acceleration is no less important than the positioning speed. While ensuring high speed and high acceleration, there are also some contradictions. This requires the manufacturer of laser cutting machine to carefully measure the relationship between the two, and find out the best matching value through repeated experiments and calculations.
