How to CNC machining aluminum?



Step 1. Convert the CAD file into a language that CNC machines can work with, that's G-code.


Step 2. The operator will place the aluminum workpiece that is cut to a specific size on the machine bed. Then it is time to mount the aluminum workpiece on the machined bed or by a vice.


Step 3. As the computer controls the CNC cutting tools to move to the pre-set coordinates, so precise positioning and alignment of the aluminum workpiece is significant to manufacture high-accuracy parts. Special metrology tools, probes, for instance, are ideal solutions for this step.


Step 4. Then, the aluminum workpiece is ready for machining. The machine uses professional cutting tools and rotating the at high speeds to remove material from the workpiece. However, at the very first steps, the machine removes at a relatively low speed and accuracy to gain an approximate geometry.


Step 5. Sometimes, the model is not being to achieve full features by single setup from the cutting tools, then to flip the aluminum workpiece is necessary.

Frequently Asked Questions

1. How much does it cost to CNC machining aluminum parts?

Prices are based on the structure of the part, order volume, machining processes, etc. You can use our instant quoting engine to get price, or you can email for more information.

2. What is aluminum CNC machining?

Aluminum CNC machining is the process of cutting and removing excess materials on the aluminum workpiece until the final object with desired geometries. Aluminum CNC machining can create complex aluminum parts with high accuracy.

3. What kind of finishes are possible with aluminum CNC machining?

We provide various surface finishing options, including as machined, polishing, sandblasting, plating, coloring, lase etching, heat treatment, screen printing, anodizing, etc. Please check details Here.

4. Is aluminum CNC parts durable?

Aluminum is the ideal material to make mechanical parts, anodizing will help aluminum parts have harder outer layer which is resistant to corrosion and impact.

5. Will aluminum CNC parts rust?

Aluminium doesn't rust. But please keep in mind that pure aluminum is a highly reactive metal.
