Owning a few machines for your own use is a luxury, many of us cannot afford it, and it is usually expensive. However, this is something that a large number of us may dream of, and through some common tools and cheap electronic products, some people have assembled some very cheap CNC machines.The latest is Minamil, which uses a rotating tool and binds it to an economical frame In order to make a fully functional CNC milling machine set up to work.
The cost of the project is very low, about $15 per axis. Each shaft uses off-the-shelf parts, such as bearings and threaded rods, which are easy to install in the mill, and for the cutting head, which is built based on rotating tools like Dremel, its price is also low. Let us not neglect the basic free weights used.
For control, the Arduino with CNC shield powers the three-axis device, which may be most of the cost of the project. [Paul McClay] He also pointed out that many of the materials he needed to build this project can be recycled from old printers and other things, so the $45 price tag is the ceiling, not the floor.
Minamil has proven that it can mill various materials with outstanding precision.Both acrylic and aluminum can be processed with this machine, but [Paul] It also demonstrated its ability to mill PCBs. It does have some limitations, but in terms of price, even when compared with his previous CNC builds that repurpose old CD drives, this factory seems to be unmatched.
