What are the characteristics of precision parts processing

What are the characteristics of precision parts processing? Five axis linkage processing center is a processing center with high technology content and high weekly density, which is specially used to process complex curved surface. This processing center system has full weight lifting influence on aviation, sail sea, military, scientific research, sophisticated equipment, high-precision medical equipment and other industries in a country.

1、 What is a five axis machining center

Five axis linkage machining has the characteristics of high efficiency and high precision, and the complex machining can be completed as soon as the workpiece is clamped once. It can be suitable for the processing of present moulds such as auto parts, aircraft structural parts, etc. There is a big difference between five axis machining center and pentahedral machining center. Many people don’t know this. They mistakenly regard the pentahedron machining center as a five axis linkage machining center. Five axis machining center has x, y, Z, a, C five axis, XYZ and AC axis to create five axis machining, specializing in space surface processing, special-shaped processing, hollow processing, drilling, oblique hole, oblique cutting, etc. The “pentahedron machining center” is the same as the three-axis machining center, but it may as well do five faces at the same time, but it can not do special-shaped processing, such as drilling, cutting bevel, etc.

For the rest, the practical boundary of the five axis CNC machining center is quite ordinary. It is understood that the current five axis CNC machining center system is the only way to process impellers, blades, marine propellers, heavy-duty generator rotors, automobile wheels, large diesel engine crankshafts, etc.

2、 Advantages of five axis machining center

1. Reduce processing time and improve processing accuracy.

The big characteristic of five axis machining center is that it is advisable to process all five surfaces by one-time clamping. That is the so-called processing angle avoidance. If it’s a linked bed, axis C can rotate endlessly, and axis a can rotate by 130 degrees. These characteristics of the equipment make it possible to process without interference.

The advantage of this method is that one-time clamping can not only finish the processing, but also prevent the repeated positioning deviation caused by repeated clamping. At the same time, it also saves a lot of time and improves the working efficiency. It can reduce the time from product to delivery and reduce the inventory.

2. Reduce equipment investment cost, workshop area and workshop number.

The five axis linkage machining center controls the compound machining machine, usually with turning performance, which can be included from lathe to milling machine to vertical mill. Everyone knows that the value of vertical mill equipment is quite high at present. After cost, processing beat and other accounting, we can find that the value of five axis is high. Before that, many people’s production and processing may be based on engineering segmentation. The problem with such a 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 needs the early waiting time for debugging, and with the popularity of all kinds of complete machine simulation software in China at present, even if only the introduction of rough data is required, the programming can be completed and the early planning can be greatly reduced. So at present, overseas auto parts and high-end manufacturing are basically based on five shafts.

3. No need for unique fixture, can complete automation.

Another prominent feature of the five axis is that the dependence on the fixture will be reduced. The rule workpiece can be clamped directly with three claws and four claws chuck, while the rule workpiece can be clamped with one side and two pins. At the same time, the five axis machining center can complete the automation of the workshop and reduce the number of people. For example, machining robot’s key point and base. In the past, horizontal plus and vertical plus combined processing were used. Now, only zero point tray and five axis linkage processing center are used to complete 24-hour operation processing.
