The more axes the new cnc 5 axis milling machines have, the better. How should I choose a five-axis machine tool?

Among the many parameters of the machine tool, one data attracts special attention, that is the number of axes. Especially when some new machine tool products are released, companies will always emphasize the number of axes to highlight the good performance of the machine tool. Recently, the editor also discovered in the communication with some netizens that many people like to "discuss the level by the axis", especially some non-industry netizens, always think that multi-axis is really powerful. So is it true that the more axes the machine tool has, the better? What parameters should be considered when selecting a five-axis machine tool? Today I am here to talk to you about this issue.

About the number of machine axes

The machine tool axis mentioned here refers to the degree of freedom of the machine tool, and several axes represent several degrees of freedom. For example, the usual three-axis refers to the plane movement of the worktable plus the up-and-down movement of the tool, and the four-axis refers to the rotation of the workpiece or the rotation of the worktable in addition to the previous three axes. Theoretically speaking, the more the number of axes, the higher the degree of freedom of machine tool processing, and the stronger the functionality of the machine tool, but this does not mean that the more axes the better, the reasons are as follows.

1. In addition to the number of axes, but also the linkage

Whenever it comes to several axis machine tools, it is followed by a few linkages. As mentioned earlier, the axis of the machine tool refers to the degree of freedom of machine tool processing, and the linkage of the machine tool means that the servo axes (excluding the spindle) can perform interpolation at the same time. For example, the five-axis five-linkage means that the five motion axes can coordinate the movement at the same time when processing the workpiece. If one or two of the five axes cannot move simultaneously with other axes, then this machine tool is called "five-axis four-linkage" or "five-axis three-linkage". Theoretically speaking, the number of axes can reach more than a dozen, dozens or even hundreds of axes, but the linkage may not be so high, which is why five-axis and five-linkage machine tools are regarded as important national equipment resources. So whenever a multi-axis machine tool comes out, there are always netizens who want to emphasize linkage, because linkage can more three-dimensionally show the performance of the machine tool.

2. In addition to degrees of freedom, precision and rigidity are also important

Machine tools refer to machines for manufacturing machines. There are many types and wide ranges, and they play an important role in the modernization of the national economy. For different processing, the requirements for the type and performance of the machine tool are also different. Therefore, although multi-axis can bring higher processing freedom and functionality, in many cases, the workpiece to be processed is not so complicated, but it affects the accuracy and performance of the machine tool. Rigidity requirements are higher. At present, multi-axis machine tools have obvious advantages in complex workpiece processing and efficiency, but do not have an absolute advantage in precision. On the contrary, the rigidity of the machine tool is slightly weak because of the complex body design. In short, it is best to be suitable for processing. In the face of different workpieces to be processed, the more axes of the machine tool, the better.

About the selection of five-axis linkage machine tools

Although not all processing requires the use of five-axis linkage machine tools, five-axis linkage machine tools do represent the high-end level of machine tools and are an effective means to solve complex machining of impellers, blades, marine propellers, and heavy-duty generator rotors. With the development of the manufacturing industry, the processing requirements for machine tools are getting higher and higher, and the consumer market for five-axis linkage machine tools is also expanding. So what parameters can be referred to when selecting a five-axis linkage machine tool? The following editor briefly introduces that the five-axis linkage processing machine tool is still a special machine tool due to the diversity of the parts to be processed and the constraints of the speed, precision and rigidity of the machine tool. Therefore, the design and selection of a five-axis machine tool must first start with the processed part and the typical machining trajectory, that is, the relative motion trajectory characteristics of the tool and the part, the tool motion accuracy/speed/space, the classification and accuracy inspection of the five-axis machine tool motion axes Wait.

In addition, in the design and selection of high-speed five-axis linkage machine tools, the following basic principles must be observed. 1. Do the machine tool structure motion characteristics conform to the motion trajectory characteristics of the tool relative to the part surface? 2. Does the "composite motion accuracy" of the machine tool meet the requirements of the tool motion trajectory accuracy and motion speed? 3. Does the size and specification of the machine tool meet the space required for the tool movement track? If there are no problems with the above, it can basically be determined that the selected five-axis linkage machine tool meets the processing needs.
