What Is Five-Axis Linkage Machining Center
The five-axis linkage machining center has the characteristics of high efficiency and high precision, and the pentahedron can be processed in one clamping of the workpiece. If it is equipped with a high-end CNC system with five-axis linkage, it can also perform high-precision machining of complex spatial surfaces, and it is more suitable for the processing of modern molds such as auto parts and aircraft structural parts. There are two ways for the rotary axis of the vertical five-axis machining center. One is the rotary axis of the worktable. The worktable set on the bed can rotate around the X-axis, which is defined as the A-axis. The general working range of the A-axis is +30 degrees to – 120 degrees. There is also a rotary table in the middle of the worktable, which rotates around the Z-axis at the position shown in the figure, which is defined as the C-axis, and the C-axis rotates 360 degrees. In this way, through the combination of A-axis and C-axis, except for the bottom surface of the workpiece fixed on the table, the other five surfaces can be processed by the vertical spindle. The minimum division value of A-axis and C-axis is generally 0.001 degrees, so that the workpiece can be subdivided into any angle, and inclined surfaces, inclined holes, etc. can be processed.
If the A-axis and C-axis are linked with the XYZ three linear axes, complex spatial curved surfaces can be processed. Of course, this requires the support of high-end CNC system, servo system and software. The advantage of this setting is that the structure of the spindle is relatively simple, the rigidity of the spindle is very good, and the manufacturing cost is relatively low. But generally, the worktable should not be designed too large, and the load-bearing capacity is also small, especially when the A-axis rotation is greater than or equal to 90 degrees, the workpiece cutting will bring a large load-bearing moment to the worktable. The other is to rely on the rotation of the vertical spindle head. The front end of the spindle is a swivel head, which can revolve around the Z-axis 360 degrees to become the C-axis. The swivel head also has an A-axis that can rotate around the X-axis, generally up to ±90 degrees or more, to achieve the same function as above. The advantage of this setup is that the machining of the spindle is very flexible, and the worktable can also be designed to be very large. The huge fuselage of a passenger aircraft and the huge engine casing can be processed on this type of machining center.
This design also has a big advantage: when we use a spherical milling cutter to process a curved surface, when the centerline of the tool is perpendicular to the processing surface, since the linear velocity of the vertex of the spherical milling cutter is zero, the surface quality of the workpiece cut out by the vertex will be very poor. The design of the spindle rotation is adopted, so that the spindle rotates at an angle relative to the workpiece, so that the spherical milling cutter avoids the vertex cutting, and ensures a certain linear speed, which can improve the surface processing quality. This structure is very popular for high-precision surface machining of molds, which is difficult to achieve with rotary machining centers. In order to achieve the high precision of rotation, the high-grade rotary shaft is also equipped with a circular grating scale feedback, and the indexing accuracy is within a few seconds. Of course, the rotary structure of this type of spindle is relatively complex, and the manufacturing cost is also high.
The Features And Advantages Of 5 Axis CNC Machines
The five-axis linkage CNC machine tool system is the only means to solve the machining of impellers, blades, marine propellers, heavy generator rotors, steam turbine rotors, large diesel engine crankshafts, etc. It is a high-tech, high-precision machine tool specially used to process complex curved surfaces. The machine tool system has a pivotal impact on a country’s aviation, aerospace, military, scientific research, precision instruments, high-precision medical equipment and other industries. force. The use of five-axis linkage machine tool makes it easy to clamp the workpiece. There is no need for special fixtures during 5 axis machining , which reduces the cost of fixtures, avoids multiple clamping, and improves mold manufacturing accuracy.
Using five-axis linkage technology to process molds can reduce the number of fixtures used. In addition, the tool cost is reduced because the five-axis simultaneous machine can save many special tools in machining. The five-axis linkage machine tool can increase the effective cutting edge length of the tool, reduce the cutting force, improve the tool life and reduce the cost during 5 axis machining .
Using the five-axis linkage machine tool to process the mold can quickly complete the mold manufacturing, fast delivery, better guarantee the cnc machining quality of the mold, make the mold manufacturing easier, and make the mold modification easier. In traditional mold manufacturing, vertical machining centers are generally used to complete the milling of workpieces.
With the continuous development of mold manufacturing technology, some weaknesses of the vertical machining center itself are becoming more and more obvious. Modern mold manufacturing generally uses ball-end milling cutters. The benefits of ball-end milling cutters in mold manufacturing are very obvious. However, if a vertical machining center is used, the linear speed of the bottom surface is zero, so the finish of the bottom surface is very poor. , If the four- and five-axis linkage machine tool manufacturing technology is used to process the mold, the above shortcomings can be overcome.To sum up, the five-axis linkage machine tool mainly has the following characteristics:
- Can effectively avoid tool interference;
- For straight-grained surface parts, side milling can be used for one-knife forming;
- For general three-dimensional profiles, especially large flat surfaces, the end face of a large-diameter end mill can be processed close to the surface;
- Multi-surface and multi-process machining can be performed on multiple spatial surfaces on the workpiece at one time;
- During five-axis machining, the tool can be in the most effective cutting state relative to the workpiece surface. The error distribution on the surface of the part is uniform;
- In some machining occasions, a larger size tool can be used to avoid interference for machining .
The Development Status And Trend Of 5 Axis CNC Machine
Foreign five-axis CNC machine tools appeared to adapt to the cnc machining of polyhedron and curved parts. With the new development of machine tool composite technology, on the basis of CNC lathes, turning and milling centers that can perform milling are quickly produced. The machining efficiency of five-axis CNC machine tools is equivalent to two three-axis machine tools, and sometimes it can even completely save the investment of some large-scale automated production lines, which greatly saves the floor space and the turnaround time and cost of working between different manufacturing units.
At present, the domestic five-axis linkage CNC machine tools already have vertical, horizontal, gantry and floor-type machining centers in terms of varieties, which are suitable for the cnc machining of miscellaneous parts of different sizes, plus five-axis linkage milling machines and large boring and milling machines, as well as turning and milling. The development of the center basically covers the needs of the domestic market. In terms of accuracy, the high-precision machining center of Beijing Machine Tool Research Institute, the NJ25HMC40 horizontal machining center of Ningjiang Machinery Group Co., Ltd., and the TH61160 horizontal boring and milling machining center of Jiaoda Kunji Technology Co., Ltd. Products from developed countries are comparable. The first is the use of linear motor drive technology.
After more than ten years of development, linear motor technology has become very mature. The problems that linear motors are susceptible to interference and large heat generation have been solved. The positioning technology of linear motors not only stops quickly during high-speed movement, but also some machine tool manufacturers use damping technology to solve them. The advantages of linear motors are linear drive, no transmission chain, no wear, and no backlash, so they can achieve the best positioning accuracy. Linear motors are highly dynamic, with accelerations exceeding 2g. The use of linear motor drive also has the characteristics of high reliability and maintenance-free.
The second is the use of dual-drive technology. For a wider worktable or a gantry type, if an intermediate drive is used, the actual driving force cannot be guaranteed to be in the center, and it is easy to cause tilting, resulting in poor dynamic performance. With dual drives, dual scales, and one drive module, the dynamic performance is perfect. One drive command, two drives work at the same time, the grating ruler detects whether the two points are balanced, if not, it will be balanced by different commands. Of course, the development of five-axis linkage machine tool technology is far more than that, and many technologies will be reflected in DMG’s machine tool products.
