What is 5 axis CNC machining center

5 axis CNC machining center means that the workpiece can be automatically operated from five sides at the same time. In addition to automatic movement along the X, Y, and Z axes, a five-axis CNC machine tool can also select two of the three rotation axes (A, B, C) for use. The A, 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. Usually very suitable for extremely complex and strong parts that must be cast. 5-axis machining requires longer preparation time for CNC programming to accommodate complex rotary motion, but allows all five faces of the workpiece to be machined in one operation. This multi-dimensional rotation and tool movement give the B axis unparalleled accuracy, smoothness and speed in the production of workpieces. It can manufacture complex 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 true 5-axis machining. Five-axis indexing machining is also called 3+2 machining, which cannot maintain continuous contact between the tool and the workpiece on all rotating axes. True 5-axis machining simultaneously uses the three linear axes (X, Y, and Z) and two rotary axes (A and B) of the machine tool to produce more complex contour surface machining. 5-axis indexing is very suitable for parts that do not require extreme contour control, such as fixtures, fixtures, housings and other parts often used in manufacturing. If you need to make a functionally superior design, then true 5-axis machining may be your best choice. Five-axis machining configuration Five-axis machine tools have two main configurations: Rotary Rotary Type: These machines utilize the rotating shaft by rotating the main shaft. This style is best for processing heavier parts, because the workbench is always level. Trunnion type: The trunnion type machine has a movable table, which is very useful for processing large batches because the spindle does not take up space. The specific type of machine used depends on various factors of your work, including the weight of the parts and the number of finished products. The advantages of five-axis machining: reduce processing time. In five-axis machining, flat-bottomed end mills are used to keep the complex mold processing surface in a vertical state, which can greatly shorten the processing time. The principle of the five-axis machining center is also suitable for bevel side milling, which can eliminate the ribbed lines caused by the ball-end milling cutter, make the surface quality of the mold more ideal, and reduce the need for cleaning the mold. Manual milling and manual work workload. Complex designs The additional motion available in 5-axis machining enables you to achieve complex shapes and designs. With a five-axis machine, you can access machining angles and arcs that were previously only possible with multiple settings and countless special fixtures. Ultimately, five-axis machining eliminates the need to create complex fixtures because you can fix the part at a time and rotate it in one process to obtain the desired geometry. Improve machining accuracy. The five-axis machining technology solves the problem that the workpiece needs to be repositioned at a complex angle and needs to be debugged multiple times, which not only shortens the time, but also greatly reduces the error generated. The tooling and fixture required to install the workpiece also saves a lot of costs. The machine tool also realizes the processing of complex parts, such as the drilling, taper processing, and cavity grooves required for complex curved surfaces. These are not traditional methods that can be used. Faster material removal In 5-axis machining, the tool stays tangent to the cutting surface, thereby reducing cycle time. This helps save costs because you have to remove more material every time you cut the tool. Better surface finish The fourth and fifth axis can help you position the part and bring the part closer to the cutting tool, allowing you to use a shorter cutting tool and being less susceptible to vibration at extremely high cutting speeds, thus helping you Get a better surface finish. The high-productivity five-axis machining center can effectively reduce the machining time and auxiliary time of the parts. The five-axis machining center has a wide spindle speed and feed range, which enables the machine tool to perform powerful cutting with a large amount of cutting. The five-axis machining center is currently 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 reduces the turnaround time between semi-finished products and improves production efficiency. Although the advantages of five-axis over four-axis and three-axis are very prominent, not all products are suitable for five-axis machining, and those suitable for three-axis machining are not necessarily suitable for five-axis machining. If you use products that can be processed by three-axis and five-axis, not only will it increase the cost, but the effect may not be good. Only by rationally arranging products and developing suitable machine tools can the value of machine tools be brought into play.
