OK, so if you came to this question from the tittle to help out someone with little experience, I thank you in advance.
So I am happy with feed and speeds etc, but I am having some issues making a particular part. It is 316 stainless, so I am taking fairly easy cuts. I mention that only in relation to the forces being put on the part for holding it.
Ignore the click ring and the glass of course, on the first picture.
I do not have a probe on my milling machine and so have attempted to first prep some stock from a solid piece of round bar , pre cut to a few mm thicker than I need in my vice and machine out the seat where the glass goes (in that first picture) and then a hole through the middle so I can use an expanding clamp and tighten the bolt down.
I did add a feature to the drawing to try and locate the part onto another expanding clamp when I flip it over and then planned to machine that feature out near the end. It has to be located perfectly of course, or it is just not going to work out. I made a mistake on the clamp , so have not been able to use that and have to order some online.
I still need to then take the case after I have machined the inside steps, which include three different dimeters inside from the back, a slot and threads where the case back will screw on, the top side done and getting that lug profile perfect (where the strap attaches) to then machine out the area on the winding crown and drill the holes for the that and the straps.
So I thought that before I order more clamps (not the cheapest things) I would ask here, how others might make this part. It is not a one off, but will be made in very low volume though.
I have no access to a lathe or probe at this time and what I need to do is prove I can actually make this, before I can invest in another machine, which I am ready to do once I have made several of these parts and they are up to spec.
So given that information, can I ask how you would attack this part?
