3 important Tips for Cutting Aluminum with your CNC Router
Most people often use the CNC wood routers to cut wood or acrylic. But CNC routers also can cut aluminum. Here are 3 tips to help you.
1. Use Carbide router bits
Carbide-coated cutters can handle the high RPMs that you need for routing aluminum. Even HSS won’t be able to handle the job. Don’t forget to tell you feed and speed calculator that your bit is carbide-coated; it will give you more RPMs.
2. Feed and Speed Rates
Cutting Aluminum is different with wood cutting. This is why you need to calculate your feed and speed rates. The best way to do this is to use and online feed rate calculator.
3. Use Fewer Flutes
You may be used to using a four-flute cutter for your woodwork, however when you’re cutting aluminum, a three-flute cutter is your maximum. This will prevent overly large chips which can cause your router to jam. The fewer the flutes, the better. If you have 4 or more flutes, chips jam your flutes, and your bit breaks.
