From the gantry structure to the bilateral drive laser cutting machine how much do you know?

  With the laser processing applications to high-speed, high-speed, high stability of the development requirements and control technology development, gantry structure with its unique structural advantages to become the world's mainstream models.

  Gantry structure, helical gear rack, bilateral drive ... ... laser cutting machine these features you understand?

  1. what are the characteristics of laser cutting machine?

  The application of laser cutting machine in industrial products has been developed rapidly in recent years. Its near infrared wavelength (1080nm) is also more favorable for the absorption of metal materials, especially in the field of high power welding and cutting. Processing capacity and economy. Compared with the gas CO2 laser, fiber laser cutting equipment has the following characteristics: low maintenance, low power consumption, low operating costs; fiber transmission, no reflection lens, no need to adjust the external optical path; low power consumption, laser no working gas consumption, Energy saving and environmental protection. At the same time, near-infrared wavelength laser is more likely to cause harm to the human body, especially for eye damage, requiring better sealing equipment and other protective functions.

  2. why should the use of laser cutting machine gantry structure?

  CNC laser cutting equipment is usually used in the structure of gantry type, cantilevered, the middle inverted beam and so on. But with the laser processing applications to the high-speed, high-speed, high stability of the development requirements and control technology development, gantry structure with its unique structural advantages to become the world's mainstream models, but also many well-known brand laser cutting machine The type of structure used by the manufacturer.

  3. what is the characteristics of laser cutting machine?

  Fiber laser cutting equipment in the metal plate cutting applications, compared with the traditional CO2 laser cutting machine, the change is outside the optical path, cutting head, auxiliary gas. The laser can be transmitted directly to the cutting head through the optical fiber, the optical path is stable and reliable to ensure the consistency of the whole frame cutting, and the machine does not need outside the optical path to protect the gas, will not be equipped with air compressor and other processing system; laser to the cutting head after collimation , Focusing can usually be configured focal length 125mm or 200mm focusing mirror, focusing lens and nozzle should be equipped with protective lenses to prevent the focus mirror from contamination; fiber laser has a good focusing performance, short focus, narrow cutting width (Up to 0.1mm), higher speed, suitable for rapid cutting of the thin plate.

  4. laser cutting machine Why use helical gear rack to drive?

  CNC machine tools commonly used in several linear shaft drive ball screw, rack and pinion, linear motor. Ball screw is usually used in the low-speed small trip CNC machine tools; gear rack is widely used to achieve high speed, large travel; linear motor used in high speed, high acceleration, a special structure of CNC machine tools. In addition, the rack and pinion is divided into two kinds of straight and helical teeth. Helical teeth relative to the straight teeth, meshing area larger, gear and rack drive will be more stable.

  5. laser cutting machine bilateral drive what are the characteristics?

  Gantry-type structure of the laser cutting machine has two forms of movement, one is to move the gantry moving but the table fixed, the second is the gantry fixed and the table to move. For large format, high speed and high performance laser cutting machine, usually using the first form, because the table with the workpiece movement is not suitable for high-speed and thick plate cutting. The bilateral drive ensures that the beam is balanced and the beam runs synchronously. And some manufacturers of laser cutting machine using gantry unilateral drive, servo motor installed in the gantry beam one end, and then through a long axis will drive to the other end, to achieve double gear rack drive, single servo motor drive. Unilateral drive makes the beams at both ends of the force asymmetry, affecting the synchronization accuracy, reduce the dynamic performance of the machine.
