Custom Aluminum 5-Axis CNC Milled Expansion Tank

It was directly processed by a 5-axis machining center. Unlike traditional 3-axis machining, which operates along three linear axis, 5-axis milling adds two rotational axes, enabling the cutting tool to approach the workpiece from virtually any angle.

Material and process

These expansion tanks are made from aluminum alloy.  Aluminum's low density reduces overall system weight, an important consideration in automotive applications. Additionally, aluminum's thermal conductivity helps dissipate heat from the fluid, preventing overheating, while its resistance to rust and chemical degradation ensures longevity.

Below are the tanks' 3D drawings:

The expansion tanks are milled by 5-axis machine with machining surface. This multi-axis machine enables the cutting tool to work from virtually any angle with high precision and efficiency. A key benefit is it can complete complex machining operations in a single setup. This not only enhances dimensional precision but also decrease setup time.

Below are the finished products:

The cost of five-axis machining machines is relatively high, the customers pursue cost-effectiveness and have no strict requirements for the surface. To reduce the cost, the lines are relatively thick and the machining marks are obvious.
