I believe that everyone does not know much about the technical processing of impellers, and even if they do, they are not very thorough. Many people think that processing technology is relatively difficult. Indeed, no matter what aspects of this processing technology, its technical content is relatively high, and programming operations are also extremely difficult. It can be said that its difficulty level is high in all aspects. Very high. The selection of processing technology for five-axis machining impellers is very important. The correctness of the selection, the rationality of the heat treatment process of the part itself, the scientific formulation of the processing technology, the accuracy and reliability of the tool selection, and the impact of temperature changes on the machine tool There are many factors such as the influence of parts and the technical level of the operator. So what are its positioning principles? Next, let me briefly introduce it to you.

1. When processing the datum and completing the processing of each station on the machining center, the selection of the positioning datum must consider completing as much processing content as possible. Generally, the processes completed on the machining center are arranged at the back. In order to prevent the finished parts from undergoing multiple unimportant dimensional processing, resulting in deformation, bumps and scratches, the subsequent processes need to be considered to a certain extent. .

2. When processing, we should try our best to make the positioning datum coincide with the design datum, which can ensure the processing accuracy to a certain extent. Through the calculation of the dimensional chain, the geometric tolerance range between the positioning datum and the design datum is strictly specified, and the processing of all key precision parts can be completed in one clamping.

3. We will inevitably encounter some major problems when we are technicians. When the positioning datum of a part is difficult to coincide with the design datum, we should analyze the assembly drawings to determine the design function of the design datum of the part.

In summary, the above is the editor’s preliminary understanding of this product. If you want to know more, please call us at Xiehe Processing.
