Why do complex parts need to choose 5-axis CNC machining?

When we want to make complex and precise parts, our preferred process is CNC machining. CNC machine tools are also divided into three-axis, four-axis and five-axis machining, depending on the complexity and precision requirements of the parts. Five-axis machining is the most efficient because it operates in a more complex and flexible manner. And the five-axis CNC machining center is a type of CNC machining center to meet the special needs of CNC machining.

What is CNC five-axis machining?

Five-axis machining is a way of CNC machine tool machining. Compared with the common three-axis machining (X, Y, Z three degrees of freedom), it refers to the machining of parts with complex geometry, which requires the tool to be able to be positioned and connected in five degrees of freedom.

Some Reasons to Choose Five-Axis CNC Machining

1. Suitable for manufacturing complex parts

Five-axis machining is often used in the aerospace field to process more complex parts, such as body parts with free surfaces, turbine parts and impeller parts. The five-axis machine tool can process different sides of the workpiece without changing the position of the workpiece on the machine tool, which can greatly improve the processing efficiency of prismatic parts.

2. Maintain the best cutting state of the tool and improve cutting conditions

When the part has a curved surface, as the three-axis tool moves towards the top or edge of the workpiece, the cutting state gradually deteriorates. To maintain optimum cutting conditions here, the table rotates. If we want to finish an irregular plane, we have to rotate the table multiple times in different directions. It can be seen that the five-axis machine tool also avoids the situation that the center point line speed of the ball end milling cutter is 0, and achieves better surface quality.

3. Reduce the number of clamping, one fixture can complete five-sided processing at the same time

In actual processing, only one clamping is required, and the processing accuracy is easier to be guaranteed. At the same time, due to the shortening of the five-axis machining center process chain and the reduction in the number of equipment, the number of fixtures, workshop area and equipment maintenance costs are also reduced. That means more efficient, higher quality machining with fewer fixtures, less floor space and less maintenance!

In fact, for the five-axis machine tool, it is just a tool for us to achieve the processing effect. The most important thing is our process determines which processing method to choose. We have good judgment on the processing methods of products, which can effectively improve production efficiency. If you are interested in CNC machining, welcome to contact us for a quotation.
