What others call fine-gloss finish we call roughing
Yesterday we undertook a practical exercise; the roughing of a piece of 316L steel. Roughing simply means removing the top layer of material rapidly in order to prepare a surface for machining. In other words, think of it as levelling your block before starting the build of a house.
The tool of choice was a 4mm end mill. The machining was done in the Kern Pyramid Nano and it was Andrew and Josh's first job in the workshop.
After the milling operation the surface finish was so smooth and even that it left them speechless. Actually it's so good that the process can be applied straight away to watch bridges and finish.
We can only imagine what kind of surface we will achieve with a diamond or ceramic tool.
Certainly the credit goes to the hydro-static guides of the Pyramid Nano.
