We all know that the impeller is the core component of the aeroengine and an important part of five-axis machining. It can play its main role to a certain extent. However, its structure is complex and the blades are severely twisted. The processing difficulty factor is very high. Generally, it is very easy to cause problems such as tool collision and interference during processing. Therefore, in order to avoid multiple unexpected phenomena, many CNC manufacturers often perform pre-processing simulation work when processing impellers. This is a very important step and indispensable! Generally, we use UG software to build a virtual manufacturing simulation platform. This platform can simulate the processing program in real time and accurately, and can effectively and efficiently avoid all impacts and collisions under a series of operations. So how much do you know about the processing process of five-axis machining of impellers? Next, let me briefly introduce it to you.

Five-axis machining is a relatively difficult process in terms of programming difficulty, with relatively high technical content and relatively high machining precision. Therefore, the requirements for processing are very large. If it is not a professional person, it is impossible to successfully complete the processing project. The geometric selection and usage requirements of the impeller have very high standards, and its basic processing flow is also based on its usage requirements.

Its processing flow is as follows:

The first step is to turn the basic shape of the rotary body on the forged aluminum material, and the whole body can be basically formed.

The second step is to roughen the flow channel. This process is very important to the overall process. It can also be said to open a "path" for later projects.

The third step is to semi-finish the flow channel part;

The next step is blade finishing. The impeller is an integral part of the impulse turbine rotor. It can be classified according to its shape and opening and closing conditions. The processing of the blades can make the later processing effect more refined.

Then clean the rounded part.
