What are the characteristics of precision parts processing? The five-axis linkage machining center is a machining center with high technology content and high precision, which is specially used for processing complex curved surfaces. This machining center system is for a country's aviation, navigation, military, Scientific research, precision instruments, high-precision medical equipment and other industries have a significant influence.
1. What is a five-axis machining center?
The five-axis linkage machining has the characteristics of high efficiency and high precision, and the workpiece can be assembled in one time. It can adapt to the processing of current molds such as auto parts and aircraft structural parts. The five-axis linkage machining center and the pentahedron machining center are very different. Many people don't know this and mistake the pentahedron machining center as a five-axis linkage machining center.
The five-axis linkage machining center has five axes of X, Y, Z, A, and C. The XYZ and AC axes form a five-axis linkage machining. They are good at space surface machining, profile machining, hollow machining, punching, oblique hole, and beveling. The “pentahedral machining center” is similar to the three-axis machining center, except that it can make five faces at the same time, but it can't be shaped, such as slanting holes and cutting bevels.
In addition, the five-axis linkage machining center has a wide range of applications. It is understood that the current five-axis linkage CNC machining center system is the only means to solve the processing of impellers, blades, marine propellers, heavy-duty generator rotors, automobile wheels, large diesel crankshafts, etc. .
Second, five-axis machining center advantages
1. Reduce processing time and improve processing accuracy.
The biggest feature of the five-axis linkage machining center is that it can process all five faces with one-time clamping. It is also called the processing angle avoidance. In the case of a linked machine, the C-axis can rotate without limit, and the A-axis can rotate about 130 degrees. These device characteristics allow for interference without machining.
This has the advantage that the machining can be completed in one clamping, that is, the repeated positioning error caused by multiple clamping is avoided. At the same time, it also saves a lot of time and improves work efficiency. It can reduce the time from product to delivery and reduce the inventory volume.
2. Reduce equipment investment costs, workshop floor space and number of workshops.
The five-axis linkage machining center left and right compound processing machine usually has a car function, which can be included from the lathe to the milling machine to the vertical mill. Everyone knows that the current vertical grinding equipment is very expensive, and can be calculated by cost, processing cycle, etc. It is found that the five-axis is more cost-effective. Previously, everyone's production and processing may be based on engineering division. The problem with this production method is that there is a large amount of waiting time that cannot be eliminated.
However, the engineering intensive production represented by the five-axis composite processing equipment only needs the waiting time for debugging in the early stage, and with the popularization of various types of complete machine simulation software in China, even the blank data can be imported to complete the programming. Greatly shorten the preliminary preparation. Therefore, the current foreign auto parts and high-end manufacturing are basically based on five axes.
3, no special fixtures are needed, and automation can be achieved.
Another significant feature of the five-axis is that the dependence on the fixture is reduced. The regular workpiece can be clamped directly with the three-jaw four-jaw chuck, and the irregular workpiece can be used with one side and two pins. At the same time, the five-axis linkage machining center can realize the automation and less people of the factory. For example, the joint and base of the processing robot. Previously, the use of horizontal and vertical composite machining, now only need to use the zero pallet with the five-axis linkage machining center, you can achieve 24-hour operation.
The above information about the characteristics of precision parts processing is shared here, we must strictly follow the additional drawings for processing, the actual size of the processing will certainly not be the same as the theoretical size of the drawings, but as long as the processing size is in error All parts are allowed to be qualified parts, so the requirements for precision parts processing are strictly in accordance with the theoretical size.
