I built a CNC router for machining enclosures, from a kit. The machine weighs about 200kg. I built it because I needed to machine specific types of materials and wanted a high RPM spindle and special cutters to achieve certain finishes. I was not very concerned about achieving crazy tolerances. Ready to go serious CNC mills were going to cost 50K+ and were not built for the type of parts I wanted to machine. The machine ended up costing about 5K and I spent a month building it. It was a crazy difficult process and I cannot recommend this to anyone. The result is great, but then I realized I have no time to machine stuff and that it is hardcore labour even if you are not doing the actual work, the machine is. I also have to point out that the major hurdle is mounting and holding parts, and switching tools. So if you are serious about production you need really good/fast tool changers and advanced work holding tools, and automatic tool measurement/touch off. Having to screw around with workholding and switching/touching off tools eats away massively at your time. These days if I would buy a new machine I would go for a brother speedio or robodrill (rumoured to be used for the apple watch). But I would not buy a new machine unless I could afford someone to operate it. So TL;DR - don't build a machine unless you have a really good reason to do so, and realize that machining is labour intensive work that can potentially be very dangerous if you don't know what you're doing.
In your case it sounds like you don't need very high precision parts and the parts are not very complicated? Perhaps you can go to a metal shop to have these made and you might not even need CNC machining. In any case, I would seriously just consider outsourcing the parts and not buying/building a machine and doing this yourself.
- levinb 5y agoI think y'all are right that the aluminum work should be outsourced - though I'd love to see the machine you built or details if there's a link.
