What Is 5-Axis CNC Machining?

Five-axis machining is a mode of CNC machining, including all axes of four-axis machining, and an additional rotation axis. Five-axis machine tools are today's most efficient CNC machine tools, capable of creating precise and complex parts for automotive molds, oil and gas machinery parts, titanium parts, medical, construction and aerospace products.

The fifth axis in a five-axis machine tool revolves around the B axis, and the B axis rotates around the Y axis in the X, Y, and Z planes. This multi-dimensional rotation and tool movement enable the B-axis to have unparalleled precision, smoothness and speed in the production of workpieces. Five-axis machining is suitable for very complex parts, which is why it is so important in advanced applications such as aerospace applications.

Five-axis machining is becoming more and more popular, not only because it provides the option of single-step machining (reducing delivery time), it also allows better access to the geometry of the part and increases tool life by tilting the table And processing efficiency. Ideal cutting position.

Advantages of CNC 5-axis machining

1. Single setting: Three-axis machine tools need to be set multiple times, which may lead to incorrect alignment, higher costs and other errors. Using CNC five-axis machining, we can machine complex shapes with a single setting, which improves efficiency, saves time, reduces costs and prevents operator errors.

2. Shorter cutting tools: CNC five-axis machining allows us to use shorter cutting tools because we can lower the tool head and orient the tool appropriately. This helps to achieve higher cutting speeds without putting too much pressure on the cutter. Shorter cutting tools can also reduce tool vibration, which can lead to cavities and cores. Since the vibration of the five-axis machine tool is smaller, we will see a better surface finish.

3. Complex parts: This process allows us to process complex parts that would otherwise require casting. If we have small batch production or prototype manufacturing, we can process parts in a few weeks instead of waiting for months to finish casting.

Extend tool life: We can maintain a constant chip load and the best cutting position, thereby extending the cycle time and life of the tool.

4. Hole drilling: CNC five-axis machining provides the ability to drill a series of holes with various compound angles in time. This can save a lot of time. If we use a 3-axis machine tool, we need to use different settings for each hole.

5. Avoid collision: the ability to tilt the workbench or cutting tool to prevent collision with the tool holder.

Although this manufacturing process is more popular in the aerospace industry, these useful attributes have prompted more industries to adopt this manufacturing process. Industries that benefit from this process include oil and gas, medical, alternative energy, and compressors.
