The five-axis linkage machining center is a machining center with high technology content and high precision, which is specially used for machining complex curved surfaces. This machining center system has a significant influence on a country's aviation, navigation, military, scientific research, precision equipment, high-precision medical equipment and other industries. Let's explain to you what a five-axis linkage machining center is and its advantages. The specific content is as follows:
1. What is a five-axis linkage machining center
Five-axis linkage machining has the characteristics of high efficiency and high precision. The workpiece can complete complex machining in one clamping. It can adapt to the processing of current molds such as automotive parts and aircraft structural parts. There is a big difference between a five-axis linkage machining center and a pentahedron machining center. Many people don't know this and mistakenly regard the pentahedron machining center as a five-axis linkage machining center. The five-axis linkage machining center has five axes, X, Y, Z, A, and C. The XYZ and AC axes form five-axis linkage machining, which is good at spatial curved surface processing, special-shaped processing, hollowing processing, punching, oblique holes, bevel cutting, etc. The "pentahedron machining center" is similar to a three-axis machining center, except that it can process five surfaces at the same time, but it cannot perform special-shaped processing, such as drilling oblique holes and cutting bevels.
In addition, the application scope of the five-axis linkage machining center is very wide. It is understood that the five-axis linkage CNC machining center system is currently the only means to solve the processing of impellers, blades, marine propellers, heavy generator rotors, automobile wheels, large diesel engine crankshafts, etc.
2. Advantages of the five-axis linkage machining center
1. Reduce processing time and improve processing accuracy.
The biggest feature of the five-axis linkage machining center is that all five surfaces can be processed in one clamping. This is also the so-called processing angle avoidance. If it is a linkage machine tool, the C axis can rotate without limit, and the A axis can rotate about 130 degrees. These equipment characteristics prevent interference during processing.
The advantage of this is that one clamping can complete the processing, that is, avoiding the repeated positioning error caused by multiple clamping. At the same time, one clamping also saves a lot of time and improves work efficiency. It can reduce the time from product to delivery and reduce inventory.
2. Reduce equipment investment costs, workshop space and the number of workshops.
The left and right compound processing machines of the five-axis linkage machining center usually have lathe functions, ranging from lathes to milling machines to vertical mills. Everyone knows that the current price of vertical mill equipment is very expensive. Through cost, processing cycle and other calculations, it can be found that the five-axis has a high cost performance. Previously, everyone's production and processing may be mainly based on engineering segmentation. The problem with this production method is that there is a lot of waiting time that cannot be eliminated. However, the engineering intensive production represented by the five-axis compound processing equipment only requires the initial waiting and debugging time, and with the popularization of various types of whole machine simulation software in China, even only the blank data needs to be imported to complete the programming, which can also greatly shorten the preliminary preparation. Therefore, foreign auto parts and high-end manufacturing are basically based on five axes.
3. No special fixture is required, and automation can be achieved.
Another significant feature of the five-axis is that the dependence on fixtures will be reduced. Regular workpieces can be clamped directly with three-jaw and four-jaw chucks, and irregular workpieces can be clamped with one side and two pins. At the same time, the five-axis linkage machining center can realize the automation and less manpower of the factory. For example, the joints and bases of the processing robot. Previously, horizontal and vertical machining were used for combined processing, but now only a zero-point pallet and a five-axis linkage machining center are needed to achieve 24-hour processing.
