What is 5 axis cnc machining
5 axis cnc machining means that the workpiece can be operated automatically from five sides at the same time. In addition to automatically moving along the X, y and Z axes, the five axis NC machine tool can also select two of the three rotating axes (a, B and C). A. The B and C axes rotate 180 ° around the X, y and Z axes respectively. This type of processing is used in the automotive, aerospace and marine industries. It is usually very suitable for extremely complex and strong components that must be cast.
5-axis machining requires longer CNC programming preparation time to accommodate complex rotary motion, but allows machining of all five faces of the workpiece in one operation. This multi-dimensional rotation and tool movement make the b-axis have unparalleled accuracy, finish and speed in the production of workpieces. It can manufacture complex and precision parts for artificial bones, aerospace products, titanium alloy parts, oil and gas machinery parts, automobile molds, medical, construction and military products.
Do not confuse 5-axis indexing milling with real 5-axis machining. Five axis indexing machining, also known as 3 + 2 machining, cannot maintain continuous contact between the tool and the workpiece on all rotating axes. True 5-axis machining uses three linear axes (x, y and z) and two rotating axes (A and b) of the machine tool at the same time, resulting in more complex contour surface machining. 5-axis indexing is ideal for parts that do not require extreme contour control, such as fixtures, fixtures, housings and other components often used in manufacturing. If you need to make a design with excellent functions, the real 5-axis machining may be your best choice.
5-axis machining configuration five axis machine tools have two main configurations: rotary type: these machines use the rotating shaft by rotating the main shaft. This style is most suitable for machining heavy parts because the workbench is always horizontal. Trunnion type: trunnion type machines have a movable worktable, which is very useful for processing large quantities because the spindle does not occupy space. The specific type of machine used depends on various factors of your work, including the weight of parts and the number of finished products.
Advantages Of 5 Axis CNC Machining
Reduce the processing time. In five axis machining, the flat end milling cutter is used to keep the complex die processing surface vertical, which can greatly shorten the processing time. The principle of five axis machining center is also applicable to inclined side milling, which can eliminate the rib pattern caused by ball end milling cutter, make the surface quality of die more ideal, and reduce the workload of manual milling and manual operation. Complex design the additional motion available in 5-axis machining enables you to achieve complex shapes and designs.
Using the five axis machine tool, you can access the machining angles and arcs that previously could only be achieved through a variety of settings and countless special fixtures. Finally, five axis machining eliminates the need to create complex fixtures because you can fix the part at once and rotate it in one process to obtain the required geometry. Improve the machining accuracy. Through the five axis machining technology, the problem that the workpiece needs to reposition the complex angle and needs to be debugged for many times is solved, which not only shortens the time, but also greatly reduces the error.
The tooling fixture required for installing the workpiece also saves a lot of costs. The machine tool also realizes the processing of complex parts, such as drilling, taper processing, cavity groove and so on, which can not be processed by traditional methods. Faster material removal in 5-axis machining, the tool remains tangent to the cutting surface, thus reducing the cycle time, which helps to save costs because you have to remove more material each time you cut the tool.
Better surface finish the fourth and fifth axes can help you position the part and bring it closer to the cutting tool, so that you can use shorter cutting tools and are not vulnerable to vibration at very high cutting speeds, thus helping you achieve better surface finish. High productivity five axis machining center can effectively reduce the processing time and auxiliary time of parts. The five axis machining center has a wide spindle speed and feed range, so that the machine tool can carry out strong cutting with large cutting amount. At present, the five axis machining center is entering the era of high-speed machining. The fast moving positioning and high-speed cutting of the moving parts of the five axis machining center reduce the turnover time between semi-finished products and improve the production efficiency.
Although the advantages of five axes over four axes and three axes are very prominent, not all products are suitable for five axes processing, and those suitable for three axes processing are not necessarily suitable for five axes processing. If you use products that can be processed in three-axis and five axis, it will not only increase the cost, but also the effect is not necessarily good. Only by making reasonable arrangements for products and formulating appropriate machine tools can the value of machine tools be brought into play.
