this is the build thread of my 5 axis mill turn. I am in very early stages of design but I needed somewhere to discuss a spindle lock design before I spend forever designing a spindle lock. In the end I hope this machine will have a 300*300*300 working volume. Pneumatic brakes on all rotary axis to increase rigidity for positional 5 axis and still allow for simultaneous 5 axis under lighter loads. A custom 10k rpm bt30 spindle with at least a 15 tool automatic tool changer. 5 axis with the 5th having the ability to attach a lathe chuck spin at 4000rpm then locking the spindle and adding a lathe cutting insert and turning it self into a lathe. the machine is similar to the matsurra cublex but a lot smaller, less ridged and without the whole robot pallet system.
