i am completely new but would like to get into milling parts for my business. I need to carve out molds in graphite. mostly the shape of cups and marbles. around 4" deep in a 6" deep slab. i dont need anything bigger than 12"x12" table. if someone could guide me in the right direction that would be great. i am in no hurry and have plenty of time to research how everything works.
The first thing I would do is try and find the endmills you need in those longer lengths. Kodiak cutting tools makes some, but they are pricey. Extra Extra Long Length End Mills | Kodiak Cutting Tools Then maybe modify one of the Cbeam kits and make the Z axis taller. OpenBuilds C-Beam Machine
