This project started with a relatively simple goal: enclose my DIY CNC mill to prevent metal shavings from flying all over my garage. However, I decided that if I was going to build an enclosure then it must support flood coolant for improved surface finish of machined parts and increased tool life. Of course, this requirement led me down a rabbit hole as I designed, plasma cut, welded, machined, and even large format 3D printed components for a project that quickly grew in complexity. The complete build took about 5 months of weekends, but all this work resulted in what I believe to be one of my most entertaining videos to date. Further, improvements in quality of life (no more spending hours cleaning up after milling) and surface finish of parts has made this investment of time and money worth it. So worth it that I thought everyone should have access to my design to build their own enclosure. Find my free parametric model on my website: drdflo.com/CNC-Mill.html
This video also features several upgrades to my mill, including double nut ball screws, variable lubrication system, and new spindle bearings.
