People seem to think that CNC machines can only do wood and plastics, but you can also cut aluminum if you take the proper procedures. Depending on the machine, there will be a sweet spot that you need to maintain. Since it is metal, you will have to take it a little slower. Using a calculator is extremely important as it will give you the right data so you don’t mess up or destroy you machine.
- CNC routers are most usually seen cutting through wood or plastic. This explains why some users are unaware of its proficiency with aluminum.
- Aluminum, in common with other metals, has a smaller sweet spot for feeds and speeds than is the general case with woods and plastics.
- Using a CNC router to cut aluminum is a task that requires skill. It’s best to use a speeds and feeds calculator.
“Once you know the secrets, you’ll find machining aluminum with a CNC Router is not only easy, but very productive.”
