What are the characteristics of precision parts processing? The five-axis linkage machining center is a machining center with high technology and high precision, which is specially used for machining complex curved surfaces. This machining center system is useful for a country's aviation, navigation, military, Scientific research, precision equipment, high-precision medical equipment and other industries have a significant influence.


What is a five-axis machining center


The five-axis simultaneous machining has the characteristics of high efficiency and high precision, and the workpiece can be completed with a single clamping. It can adapt to the processing of current molds such as automobile parts and aircraft structural parts. There is a big difference between a 5-axis linkage machining center and a pentahedron machining center. Many people do not 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, C. XYZ and AC axes form five-axis linkage processing. It is good at space curved surface processing, special-shaped processing, hollow processing, punching, oblique drilling, and oblique cutting. The "pentahedron machining center" is similar to a three-axis machining center, except that it can do five faces at the same time, but it cannot do special-shaped machining, such as beveling holes and cutting bevels.


In addition, the scope of application of five-axis linkage machining centers is very wide. 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 generator rotors, automotive engine wheels, large diesel engine crankshafts, etc. .


Advantages of two- and five-axis machining centers


1. Reduce processing time and improve processing accuracy.


The biggest feature of the 5-axis linkage machining center is that it can process all five faces at one time. This is the so-called processing angle avoidance. If it is a linked machine tool, the C axis can rotate without restriction, 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, repeated positioning errors caused by multiple clampings are avoided. At the same time, a single clamping 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 space and number of workshops.


Five-axis linkage machining center left and right composite machining machines, usually with turning functions, can be included from even lathes to milling machines to vertical grinding. Everyone knows that the current price of vertical grinding equipment is very expensive. It can be calculated by cost and processing cycle It is found that the cost performance of the five-axis is high. Previously, everyone's production and processing may be based on engineering division. The problem with this production method is that there is a lot of waiting time that cannot be eliminated. However, the intensive production of engineering represented by the five-axis composite processing equipment requires only the initial waiting time for debugging, and with the popularization of various domestic machine simulation software, programming can be completed even by importing the rough data, and it can also Significantly shorten the preliminary preparation. So at present, foreign auto parts and high-end manufacturing are basically based on five axes.


3. No special fixture is needed, and automation can be realized.


Another significant feature of the five-axis is that the dependence on the fixture will be reduced. Regular workpieces can be clamped directly with three-jaw four-jaw chucks, and irregular workpieces can be used with two pins on one side. At the same time, the five-axis linkage machining center can realize factory automation and less humanization. Such as processing robot joints and bases. In the past, horizontal plus vertical machining was used. Now it only needs to use a zero-point pallet with a five-axis linkage machining center to achieve 24-hour operation.


What is the above about the characteristics of precision parts processing? We must share it here. We must strictly follow the additional drawings for processing. The actual size of the processing will certainly not be exactly the same as the theoretical size of the drawing, but as long as the processing size is within the error Within the allowable range are all qualified components, so the requirement for precision component processing is to strictly follow the theoretical dimensions.
