5 axis milling machining of turbine impeller

Before adopting 5-axis CNC machining centers, most turbomachinery manufacturers used 3-axis or 4-axis machine tools to process impellers, and most of them used point machining. That is, every point on the blade surface is processed into a point by the tool tip. When the tool moves along the surface of the blade, it will leave some pits or residual sharp corners, and the height of these pits or sharp corners depends on the programming skills. Point processing is also a feasible method, but this method has some unavoidable disadvantages:

Difficulties in milling large blades of impellers

In the CNC machining of the impeller blades, the machining of large impeller blades is the most difficult. Mastering the measures to solve the processing difficulties of large blades has a very positive effect not only on the large blade itself, but also on the impeller moving blades, impeller stationary blades, guide impeller blades and impeller end blades.

3-axis and 5-axis drilling technology for aluminum parts

CNC machining holes in the solid part of the workpiece with a drill is called drilling. The drilling is rough machining, the achievable dimensional tolerance grade is IT13~IT11, and the surface roughness value is Ra50~12.5μm. Due to the long length of the twist drill, the small core diameter and poor rigidity, as well as the influence of the chisel edge, the drilling has the following technological characteristics:

Tool interference prevention for 5 axis milling

With the increase in the design of multi-faceted and complex curved parts, 5-axis machining will account for an increasing proportion of CNC machining. Because 5-axis CNC machining adds two degrees of freedom of rotation, it increases the difficulty of CNC machining motion simulation calculation and tool interference checking, especially when machining parts with extremely complex shapes.

The advantages of 5-axis machine tools

5-axis machining of 28 parts at a time
5-axis simultaneous machining of 28 parts
How do you realize the advantages of the five-axis machine? Here is an example of a Haas UMC-750P machine that processes 28 parts at the same time. Through the design of the turntable and the fixture, and the three processing surfaces of the part are combined into one processing program in the five-axis processing program, the purpose of reducing the cycle time is achieved.

What is 5-axis CNC technology? Application of 5-axis machining?
Among the different machining technologies for chip removal that exist, 5-axis machining is one of the most complex.
The 5-axis machining centers have the ability to carry out translations through the X, Y, Z axes; and rotations through two other axes A and B that can be carried out by the table or by the machine head, thus making the tool more accessible to the part to be machined.
