No matter what kind of work we do, we should understand its various indicators, especially in CNC processing, so as not to affect our work. In the process of CNC processing, we need to master certain knowledge, to be familiar with its process, so that the production process can be more smooth. When it comes to CNC machining, it is a very high precision process. There are a lot of preparations to be made. What are the main requirements? Let’s introduce CNC processing professionals to you. After understanding, I believe you will master a lot of knowledge in this area.
CNC machining in the quality requirements are very strict, and we want to do more refined and high-quality, first of all, our CNC precision has a great impact on the processing, so we should pay attention to its machining accuracy and machine tool accuracy these two different concepts. Therefore, in order to better do these aspects, we need to know more about CNC processing, because this is the most basic. First of all, we regard the position accuracy on the manufacturer’s sample or product certificate as the machining accuracy of machine tool, which is wrong. The position accuracy indicated on the sample or certificate is the accuracy of the machine itself, while the machining accuracy is the sum of the errors caused by various factors of the whole process system including the allowable error of the machine tool itself. The evaluation method of process capability can be used as the basis of precision selection. Generally speaking, the calculation result should be greater than 1.33, which is a relatively accurate basis.
In addition to the influence of precision on CNC machining, the rigidity of our machine tool will also directly affect the productivity and machining accuracy. The processing speed is much higher than that of ordinary machine tools, and the motor power is also higher than that of the common machine tools of the same specification. Therefore, the rigidity of the structural design is far higher than that of the ordinary machine tools. Therefore, we can make orders according to the technological requirements, allowable torque, power, axial force and maximum feed force. According to the value provided by the manufacturer, we will check the value of awesome products. If we understand it, it will be of great help to the quality of the products. Secondly, in order to obtain the high rigidity of the machine tool, it is not limited to the size of the parts, but the machine tool with 1 or 2 sizes relative to the size of the parts is selected.
