What is a five-axis machining center
The five-axis machining center is also called the five-axis linkage machining center. It is a machining center with high technology content and high precision specially used for machining complex curved surfaces. This machining center system has a decisive influence on a country’s aviation, aerospace, military, scientific research, precision instruments, high-precision medical equipment and other industries. At present, the five-axis linkage CNC machining center system is the only means to solve the processing of impellers, blades, marine propellers, heavy generator rotors, steam turbine rotors, large diesel engine crankshafts, etc.
Five-axis machining centers are not only used in civil industries, such as wood mold manufacturing, bathroom trimming, automotive interior parts processing, foam mold processing, European-style furniture, solid wood chairs, etc., but also widely used in aviation, aerospace, military, medical equipment, Teaching, rail transit, wind power and other industries. The five-axis machining center is a high-tech method, which makes the impossible possible, and all spatial surfaces and special-shaped machining can be realized. It can not only complete the task of mechanized processing of complex workpieces, but also can quickly improve the processing efficiency and shorten the processing flow.
Advantages of five-axis machining centers
Advantages of five-axis machining center: It can process free-form surfaces that ordinary three-axis CNC machine tools cannot process or that it cannot process at one time. For example, the blades of aircraft engines and steam turbines, the propellers of ships, and other complex molds with special curved surfaces. Since the tools and angles of the five-axis machining center can be adjusted at any time during the machining process, the interference of other tools can be avoided and all machining can be completed at one time.
Five-axis CNC machining center, five-axis CNC milling machine, good at space surface processing, special-shaped processing, hollow processing, punching, oblique drilling, chamfering, etc., widely used in aerospace, military scientific research, precision machinery and other fields, high-precision medical equipment, conventional manufacturing, etc. The five-axis machining center with automatic tool change function can easily complete the complete processing of complex parts such as milling, grooving, drilling, sawing, mortising, tenoning, etc. The five-axis machining center accessories designed by Jiabang CNC adopt international Well-known brand, more durable.
The reliability of the five-axis machining center has always been an important indicator that users are most concerned about. The numerical control system will adopt higher-integrated circuit chips, and use large-scale or ultra-large-scale dedicated and hybrid integrated circuits to increase the number of components and improve reliability.
CNC programming automation
At present, the interactive automatic programming of CAD/CAM graphics has been widely used, which is a new trend in the development of five-axis machining centers.
Modern five-axis machining centers will introduce adaptive control technology to automatically adjust task parameters according to changes in cutting conditions, so that the best task conditions can be maintained during the machining process, so as to obtain higher machining accuracy and smaller surface roughness. It can also improve the service life of the tool and the production efficiency of the equipment.
Control system miniaturization
The miniaturization of the numerical control system facilitates the integration of mechanical and electrical installations. At present, it is important to adopt ultra-large-scale integrated components, multi-layer printed circuit boards, and three-dimensional installation methods to enable high-density installation of electronic components and reduce the occupied space of the system in a large range.
Various machining centers equipped with automatic tool changing mechanism (tool magazine capacity can reach more than 100) can simultaneously complete milling, boring, drilling, turning, reaming, reaming, tapping, etc. on the same machine tool This kind of process processing, the modern five-axis machining center also adopts multi-spindle and polyhedron cutting, that is, different methods of cutting processing are performed on different parts of a part at the same time.
High speed and high precision
Speed and precision are two important indicators of a five-axis machining center, which are indirectly related to processing efficiency and product quality. At present, the numerical control system adopts a processor with a higher number of digits and a higher frequency to improve the basic operation speed of the system. At the same time, a large-scale integrated circuit and multi-microprocessor structure are adopted to improve the data processing capability of the system, that is, to improve the speed and accuracy of interpolation operations. And the linear servo feeding method in which the linear motor indirectly drives the machine tool task table is adopted, and its high speed and static response characteristics are commensurately superior. The feedforward control technology is adopted to greatly reduce the tracking lag error, thereby improving the machining accuracy of corner cutting.
