Cutting Aluminum With A Router

Bottom pilot bits trim material from an upper layer of the workpiece so that it is flush with the layer below.

Cutting aluminum with a router.

The pilot location is reversed when using the bit with a router table. You should also begin the routing process by first drilling a inch hole near the corner so as to avoid plunging the router bit through the material. Cut layers of material flush to one another or make cuts along a template. Now it is also used to cut weak metals like aluminum.

A normal carbide bit would be enough. Small hobby routers and the big 100k machines are very different. Generally a cnc router is a computer controlled machine used for cutting wood and plastic which are comparatively softer than metals. Due to the bit sticky nature of aluminum the cnc router is the best tool for cutting it without making any mess.

Any normal cnc router like benchtop or table top cnc routers are strong enough to make a hole in aluminium. Therefore in this case you need to be particularly precise when calculating the feeds and speeds. When cutting aluminum unlike cutting plastic or wood you would have a much narrower window for your feeds and speeds. However cutting aluminum using a cnc router is not a walk in the park.

There s a world of difference for a cnc router cutting thin aluminum sheet vs a cnc router cutting thicker aluminum plate. Aluminum needs a lot more rigidity that wood or plastic. The thicker the material and the greater the depth of cut the more important it is to follow these tips.

Cutting aluminum with a cnc router is very easy. Your router should be well supported when cutting the aluminum material and ensure it has a level base. While using the router on aluminum the tool may at times get into some places that are. Used a basic 1 4 shaft wood edging router bit to quickly trim the edge of 1 4 thick 6160 aluminum sheet.
