The daily application of laser cutting machine is very widespread, but many customers do not understand the structure of laser cutting machine i, so that they are confused when the laser cutting machine needs maintenance, so in order to let everyone in the laser cutting machine It is more convenient in daily operation, let’s introduce the structure of CNC laser cutting machine.  According to the relative movement of the cutting head and the worktable, the CNC laser cutting machine can be divided into three types: a fixed beam of fixed light path, a moving beam of flying light path, and a mixed light path of semi-fixed and semi-moving hybrid form. In addition, there is also a fixed optical path flying beam transmission form with an articulated movable arm, which is called a constant flying optical path, or a constant optical path for short.  The cutting machine adopts the flying light path. During the cutting process, only the cutting head moves in the X and Y directions, and the position of the worktable is fixed. The plates processed by this type of cutting machine are large in size and quality; the equipment occupies a small area, the workpiece does not need to be clamped, and the loading and unloading are convenient; the machine has good acceleration performance and high positioning accuracy. Therefore, it is highly regarded by the market and is called the mainstream model in the international market. There are many types of plane cutting machines. Several typical structures common to modern laser cutting machines are mainly gantry frame movable flying light path structure, beam movable flying light path, beam upside down movable flying light path, cantilever movable flying light path structure, fixed beam gantry type Semi-flying optical path, fixed optical path with movable cross table, gantry and cantilever constant optical path, robot structure and large format airborne hybrid optical path, laser flexible processing system, etc. No matter what kind of laser cutting machine has its own characteristics and advantages, users can choose the corresponding laser equipment according to their own production characteristics when selecting the equipment. As far as the structure of the cutting equipment is concerned, the large parts of the bed are made of casting structure, welded structure, marble structure, beams are made of aluminum alloy castings or welded parts and their profiles, and other parts include engineering plastics, glass steel, stainless steel, etc. Application of materials, etc. The laser configured in the equipment should be selected according to the user’s processing performance, processing material, shape, size, etc. Different lasers are available. The available lasers are co2 axis fast flow lasers, radio frequency board debugging lasers, swirl lasers, solid-state lasers and Fiber laser, etc. In terms of the driving mode of the equipment, the X and Y axes use unilateral servo motors with corresponding reducers, and use high-precision rack and pinion drive structures. Both X-axis and both sides use servo motors with corresponding reducers. Rack and pinion drive structure, there are double gears to eliminate the backlash drive; there is a servo motor equipped with high-precision ball screw direct drive, using disk-type large inertia motor direct gear, rack drive; there is also a linear motor directly driven Structure method.   CNC laser cutting machine is usually equipped with high-precision linear guide rails, and equipped with automatic lubrication device. The single-sided linear guide rail is equipped with a roller structure as the main guide rail, which is a typical structure that is cost-effective, economical, and convenient to adjust.   Another structure is to directly adopt the drive unit structure that combines the drive and the guide rail into one, which is easier to install, more convenient to debug, and easy to ensure accuracy, but the cost is a bit higher. The Z-axis usually uses high-precision ball screws and linear guides or drive units, and is equipped with a high-quality laser cutting head with automatic tracking of the focus height position. Usually the Z-axis selects the cutting head with automatic tracking of the focus position. For example, the cutting head adds an F-axis that can control the independent movement of the focus lens, adds a CNC-controlled compensation optical path system, and adopts an optical lens that can be controlled to change the focus curvature.   Wuhan Gaoneng Laser Equipment Manufacturing Co., Ltd. is a high-tech enterprise integrating Ru0026D, production and sales of professional laser complete sets of equipment. Not only successfully developed laser equipment with advanced technology, but also used self-support import and export rights to promote products to more than 40 global markets including Hong Kong, South Korea, Vietnam, Malaysia, Thailand, Australia, the United States, Japan, Germany, the Netherlands, Jordan, etc. The country has an advantage in the international market in the same industry.
