CNC machines are great at churning out custom parts, but they tend to make a mess in the process. [Darcy] has built up his own CNC dust collection rig to collect the dust and keep his workspace clean.
To capture the dust, a custom dust skirt encloses the cutting tool and directs the vacuum. This was made by gluing acrylic parts together, creating a box that contains the dust and provides a connection for the vacuum system.
For $1, [Darcy] built a cyclone dust extractor. This spins air around in circles, causing the dust to fall to the bottom of a container. The result is less dust reaching the vacuum, and much less money spent on vacuum bags.
Since the vacuum makes quite a bit of noise, a muffler was needed. This is just a simple wood box to contain the machine. It can also be used to vent the exhaust outside to further prevent polluting the workspace.
While we’ve seen some similar builds in the past, [Darcy]’s design could be helpful for those looking to build their own system. He also gives us a video which shows the effectiveness of the dust skirt, which you can find after the break.
