I wanted to machine a part out of aluminum that I attached.
Basically it is a 15mm hole, surrounded on two sides of a flange with cylinders that are close to the same size (20mm and 21mm). The 20mm cylinder needs an o-ring to fit in a groove.
That groove is 1mm tall x 0.85mm deep (cut into the cylinder wall from outside).
I know I should have a lathe for this specific part, but I do not have access to one. I have access to a Tormach 770m (thanks to all the people here that helped me try to pick a mill).
It seems I could machine this part by doing half, flipping it and doing the other half except that groove for an o-ring to sit in. I have been trying to figure out what sort of bit I would need to cut that. There is no rotary so I cannot put the part sideways and rotate (like a lathe too bad I don't have one). Anyway if someone can give me a heads up on the type of bit that might work I would appreciate it. I found some stuff at seco that might work, but am not sure if I am looking in the right place. Maybe an abrasive wheel could even work, but those change size so quickly I doubt it would be useful.
